Subprograms & Entries

From_Object_Free

function From_Object_Free 
(B: access Gtk_Text_Iter) return Gtk_Text_Iter;

Get_Type

function Get_Type return Glib.GType;

Assign

procedure Assign 
(Iter: Gtk_Text_Iter;
Other: Gtk_Text_Iter);

Backward_Char

procedure Backward_Char 
(Iter: in out Gtk_Text_Iter;
Result: out Boolean);
Moves backward by one character offset. Returns True if movement was possible; if Iter was the first in the buffer (character offset 0), gtk_text_iter_backward_char () returns False for convenience when writing loops.

Backward_Chars

procedure Backward_Chars 
(Iter: in out Gtk_Text_Iter;
Count: Gint;
Result: out Boolean);
Moves Count characters backward, if possible (if Count would move past the start or end of the buffer, moves to the start or end of the buffer). The return value indicates whether the iterator moved onto a dereferenceable position; if the iterator didn't move, or moved onto the end iterator, then False is returned. If Count is 0, the function does nothing and returns False. "count": number of characters to move

Backward_Cursor_Position

procedure Backward_Cursor_Position 
(Iter: in out Gtk_Text_Iter;
Result: out Boolean);
Like Gtk.Text_Iter.Forward_Cursor_Position, but moves backward.

Backward_Cursor_Positions

procedure Backward_Cursor_Positions 
(Iter: in out Gtk_Text_Iter;
Count: Gint;
Result: out Boolean);
Moves up to Count cursor positions. See Gtk.Text_Iter.Forward_Cursor_Position for details. "count": number of positions to move

Backward_Line

procedure Backward_Line 
(Iter: in out Gtk_Text_Iter;
Result: out Boolean);
Moves Iter to the start of the previous line. Returns True if Iter could be moved; i.e. if Iter was at character offset 0, this function returns False. Therefore if Iter was already on line 0, but not at the start of the line, Iter is snapped to the start of the line and the function returns True. (Note that this implies that in a loop calling this function, the line number may not change on every iteration, if your first iteration is on line 0.)

Backward_Lines

procedure Backward_Lines 
(Iter: in out Gtk_Text_Iter;
Count: Gint;
Result: out Boolean);
Moves Count lines backward, if possible (if Count would move past the start or end of the buffer, moves to the start or end of the buffer). The return value indicates whether the iterator moved onto a dereferenceable position; if the iterator didn't move, or moved onto the end iterator, then False is returned. If Count is 0, the function does nothing and returns False. If Count is negative, moves forward by 0 - Count lines. "count": number of lines to move backward

Backward_Search

procedure Backward_Search 
(Iter: in out Gtk_Text_Iter;
Str: UTF8_String;
Flags: Gtk_Text_Search_Flags;
Match_Start: out Gtk_Text_Iter;
Match_End: out Gtk_Text_Iter;
Limit: Gtk_Text_Iter := Null_Text_Iter;
Result: out Boolean);
Same as Gtk.Text_Iter.Forward_Search, but moves backward. "str": search string "flags": bitmask of flags affecting the search "match_start": return location for start of match, or null "match_end": return location for end of match, or null "limit": location of last possible Match_Start, or null for start of buffer

Backward_Sentence_Start

procedure Backward_Sentence_Start 
(Iter: in out Gtk_Text_Iter;
Result: out Boolean);
Moves backward to the previous sentence start; if Iter is already at the start of a sentence, moves backward to the next one. Sentence boundaries are determined by Pango and should be correct for nearly any language (if not, the correct fix would be to the Pango text boundary algorithms).

Backward_Sentence_Starts

procedure Backward_Sentence_Starts 
(Iter: in out Gtk_Text_Iter;
Count: Gint;
Result: out Boolean);
Calls Gtk.Text_Iter.Backward_Sentence_Start up to Count times, or until it returns False. If Count is negative, moves forward instead of backward. "count": number of sentences to move

Backward_To_Tag_Toggle

procedure Backward_To_Tag_Toggle 
(Iter: in out Gtk_Text_Iter;
Tag: Gtk.Text_Tag.Gtk_Text_Tag := null;
Result: out Boolean);
Moves backward to the next toggle (on or off) of the Gtk.Text_Tag.Gtk_Text_Tag Tag, or to the next toggle of any tag if Tag is null. If no matching tag toggles are found, returns False, otherwise True. Does not return toggles located at Iter, only toggles before Iter. Sets Iter to the location of the toggle, or the start of the buffer if no toggle is found. "tag": a Gtk.Text_Tag.Gtk_Text_Tag, or null

Backward_Visible_Cursor_Position

procedure Backward_Visible_Cursor_Position 
(Iter: in out Gtk_Text_Iter;
Result: out Boolean);
Moves Iter forward to the previous visible cursor position. See Gtk.Text_Iter.Backward_Cursor_Position for details. Since: gtk+ 2.4

Backward_Visible_Cursor_Positions

procedure Backward_Visible_Cursor_Positions 
(Iter: in out Gtk_Text_Iter;
Count: Gint;
Result: out Boolean);
Moves up to Count visible cursor positions. See Gtk.Text_Iter.Backward_Cursor_Position for details. Since: gtk+ 2.4 "count": number of positions to move

Backward_Visible_Line

procedure Backward_Visible_Line 
(Iter: in out Gtk_Text_Iter;
Result: out Boolean);
Moves Iter to the start of the previous visible line. Returns True if Iter could be moved; i.e. if Iter was at character offset 0, this function returns False. Therefore if Iter was already on line 0, but not at the start of the line, Iter is snapped to the start of the line and the function returns True. (Note that this implies that in a loop calling this function, the line number may not change on every iteration, if your first iteration is on line 0.) Since: gtk+ 2.8

Backward_Visible_Lines

procedure Backward_Visible_Lines 
(Iter: in out Gtk_Text_Iter;
Count: Gint;
Result: out Boolean);
Moves Count visible lines backward, if possible (if Count would move past the start or end of the buffer, moves to the start or end of the buffer). The return value indicates whether the iterator moved onto a dereferenceable position; if the iterator didn't move, or moved onto the end iterator, then False is returned. If Count is 0, the function does nothing and returns False. If Count is negative, moves forward by 0 - Count lines. Since: gtk+ 2.8 "count": number of lines to move backward

Backward_Visible_Word_Start

procedure Backward_Visible_Word_Start 
(Iter: in out Gtk_Text_Iter;
Result: out Boolean);
Moves backward to the previous visible word start. (If Iter is currently on a word start, moves backward to the next one after that.) Word breaks are determined by Pango and should be correct for nearly any language (if not, the correct fix would be to the Pango word break algorithms). Since: gtk+ 2.4

Backward_Visible_Word_Starts

procedure Backward_Visible_Word_Starts 
(Iter: in out Gtk_Text_Iter;
Count: Gint;
Result: out Boolean);
Calls Gtk.Text_Iter.Backward_Visible_Word_Start up to Count times. Since: gtk+ 2.4 "count": number of times to move

Backward_Word_Start

procedure Backward_Word_Start 
(Iter: in out Gtk_Text_Iter;
Result: out Boolean);
Moves backward to the previous word start. (If Iter is currently on a word start, moves backward to the next one after that.) Word breaks are determined by Pango and should be correct for nearly any language (if not, the correct fix would be to the Pango word break algorithms).

Backward_Word_Starts

procedure Backward_Word_Starts 
(Iter: in out Gtk_Text_Iter;
Count: Gint;
Result: out Boolean);
Calls Gtk.Text_Iter.Backward_Word_Start up to Count times. "count": number of times to move

Begins_Tag

function Begins_Tag 
(Iter: Gtk_Text_Iter;
Tag: access Gtk.Text_Tag.Gtk_Text_Tag_Record'Class) return Boolean;
Returns True if Tag is toggled on at exactly this point. If Tag is null, returns True if any tag is toggled on at this point. Note that the gtk_text_iter_begins_tag () returns True if Iter is the *start* of the tagged range; gtk_text_iter_has_tag () tells you whether an iterator is *within* a tagged range. "tag": a Gtk.Text_Tag.Gtk_Text_Tag, or null

Can_Insert

function Can_Insert 
(Iter: Gtk_Text_Iter;
Default_Editability: Boolean) return Boolean;
Considering the default editability of the buffer, and tags that affect editability, determines whether text inserted at Iter would be editable. If text inserted at Iter would be editable then the user should be allowed to insert text at Iter. Gtk.Text_Buffer.Insert_Interactive uses this function to decide whether insertions are allowed at a given position. "default_editability": True if text is editable by default

Compare

function Compare 
(Iter: Gtk_Text_Iter;
Rhs: Gtk_Text_Iter) return Gint;

Editable

function Editable 
(Iter: Gtk_Text_Iter;
Default_Setting: Boolean) return Boolean;
Returns whether the character at Iter is within an editable region of text. Non-editable text is "locked" and can't be changed by the user via Gtk.Text_View.Gtk_Text_View. This function is simply a convenience wrapper around gtk_text_iter_get_attributes (). If no tags applied to this text affect editability, Default_Setting will be returned. You don't want to use this function to decide whether text can be inserted at Iter, because for insertion you don't want to know whether the char at Iter is inside an editable range, you want to know whether a new character inserted at Iter would be inside an editable range. Use Gtk.Text_Iter.Can_Insert to handle this case. "default_setting": True if text is editable by default

Ends_Line

function Ends_Line 
(Iter: Gtk_Text_Iter) return Boolean;
Returns True if Iter points to the start of the paragraph delimiter characters for a line (delimiters will be either a newline, a carriage return, a carriage return followed by a newline, or a Unicode paragraph separator character). Note that an iterator pointing to the \n of a \r\n pair will not be counted as the end of a line, the line ends before the \r. The end iterator is considered to be at the end of a line, even though there are no paragraph delimiter chars there.

Ends_Sentence

function Ends_Sentence 
(Iter: Gtk_Text_Iter) return Boolean;
Determines whether Iter ends a sentence. Sentence boundaries are determined by Pango and should be correct for nearly any language (if not, the correct fix would be to the Pango text boundary algorithms).

Ends_Tag

function Ends_Tag 
(Iter: Gtk_Text_Iter;
Tag: access Gtk.Text_Tag.Gtk_Text_Tag_Record'Class) return Boolean;
Returns True if Tag is toggled off at exactly this point. If Tag is null, returns True if any tag is toggled off at this point. Note that the gtk_text_iter_ends_tag () returns True if Iter is the *end* of the tagged range; gtk_text_iter_has_tag () tells you whether an iterator is *within* a tagged range. "tag": a Gtk.Text_Tag.Gtk_Text_Tag, or null

Ends_Word

function Ends_Word 
(Iter: Gtk_Text_Iter) return Boolean;
Determines whether Iter ends a natural-language word. Word breaks are determined by Pango and should be correct for nearly any language (if not, the correct fix would be to the Pango word break algorithms).

Equal

function Equal 
(Iter: Gtk_Text_Iter;
Rhs: Gtk_Text_Iter) return Boolean;
Tests whether two iterators are equal, using the fastest possible mechanism. This function is very fast; you can expect it to perform better than e.g. getting the character offset for each iterator and comparing the offsets yourself. Also, it's a bit faster than Gtk.Text_Iter.Compare. "rhs": another Gtk.Text_Iter.Gtk_Text_Iter

Forward_Char

procedure Forward_Char 
(Iter: in out Gtk_Text_Iter;
Result: out Boolean);
Moves Iter forward by one character offset. Note that images embedded in the buffer occupy 1 character slot, so gtk_text_iter_forward_char () may actually move onto an image instead of a character, if you have images in your buffer. If Iter is the end iterator or one character before it, Iter will now point at the end iterator, and gtk_text_iter_forward_char () returns False for convenience when writing loops.

Forward_Chars

procedure Forward_Chars 
(Iter: in out Gtk_Text_Iter;
Count: Gint;
Result: out Boolean);
Moves Count characters if possible (if Count would move past the start or end of the buffer, moves to the start or end of the buffer). The return value indicates whether the new position of Iter is different from its original position, and dereferenceable (the last iterator in the buffer is not dereferenceable). If Count is 0, the function does nothing and returns False. "count": number of characters to move, may be negative

Forward_Cursor_Position

procedure Forward_Cursor_Position 
(Iter: in out Gtk_Text_Iter;
Result: out Boolean);
Moves Iter forward by a single cursor position. Cursor positions are (unsurprisingly) positions where the cursor can appear. Perhaps surprisingly, there may not be a cursor position between all characters. The most common example for European languages would be a carriage return/newline sequence. For some Unicode characters, the equivalent of say the letter "a" with an accent mark will be represented as two characters, first the letter then a "combining mark" that causes the accent to be rendered; so the cursor can't go between those two characters. See also the Pango_Log_Attr structure and pango_break function.

Forward_Cursor_Positions

procedure Forward_Cursor_Positions 
(Iter: in out Gtk_Text_Iter;
Count: Gint;
Result: out Boolean);
Moves up to Count cursor positions. See Gtk.Text_Iter.Forward_Cursor_Position for details. "count": number of positions to move

Forward_Line

procedure Forward_Line 
(Iter: in out Gtk_Text_Iter;
Result: out Boolean);
Moves Iter to the start of the next line. If the iter is already on the last line of the buffer, moves the iter to the end of the current line. If after the operation, the iter is at the end of the buffer and not dereferencable, returns False. Otherwise, returns True.

Forward_Lines

procedure Forward_Lines 
(Iter: in out Gtk_Text_Iter;
Count: Gint;
Result: out Boolean);
Moves Count lines forward, if possible (if Count would move past the start or end of the buffer, moves to the start or end of the buffer). The return value indicates whether the iterator moved onto a dereferenceable position; if the iterator didn't move, or moved onto the end iterator, then False is returned. If Count is 0, the function does nothing and returns False. If Count is negative, moves backward by 0 - Count lines. "count": number of lines to move forward

Forward_Search

procedure Forward_Search 
(Iter: in out Gtk_Text_Iter;
Str: UTF8_String;
Flags: Gtk_Text_Search_Flags;
Match_Start: out Gtk_Text_Iter;
Match_End: out Gtk_Text_Iter;
Limit: Gtk_Text_Iter := Null_Text_Iter;
Result: out Boolean);
Searches forward for Str. Any match is returned by setting Match_Start to the first character of the match and Match_End to the first character after the match. The search will not continue past Limit. Note that a search is a linear or O(n) operation, so you may wish to use Limit to avoid locking up your UI on large buffers. If the GTK_TEXT_SEARCH_VISIBLE_ONLY flag is present, the match may have invisible text interspersed in Str. i.e. Str will be a possibly-noncontiguous subsequence of the matched range. similarly, if you specify GTK_TEXT_SEARCH_TEXT_ONLY, the match may have pixbufs or child widgets mixed inside the matched range. If these flags are not given, the match must be exact; the special 0xFFFC character in Str will match embedded pixbufs or child widgets. If you specify the GTK_TEXT_SEARCH_CASE_INSENSITIVE flag, the text will be matched regardless of what case it is in. "str": a search string "flags": flags affecting how the search is done "match_start": return location for start of match, or null "match_end": return location for end of match, or null "limit": bound for the search, or null for the end of the buffer

Forward_Sentence_End

procedure Forward_Sentence_End 
(Iter: in out Gtk_Text_Iter;
Result: out Boolean);
Moves forward to the next sentence end. (If Iter is at the end of a sentence, moves to the next end of sentence.) Sentence boundaries are determined by Pango and should be correct for nearly any language (if not, the correct fix would be to the Pango text boundary algorithms).

Forward_Sentence_Ends

procedure Forward_Sentence_Ends 
(Iter: in out Gtk_Text_Iter;
Count: Gint;
Result: out Boolean);
Calls Gtk.Text_Iter.Forward_Sentence_End Count times (or until Gtk.Text_Iter.Forward_Sentence_End returns False). If Count is negative, moves backward instead of forward. "count": number of sentences to move

Forward_To_End

procedure Forward_To_End 
(Iter: in out Gtk_Text_Iter);

Forward_To_Line_End

procedure Forward_To_Line_End 
(Iter: in out Gtk_Text_Iter;
Result: out Boolean);
Moves the iterator to point to the paragraph delimiter characters, which will be either a newline, a carriage return, a carriage return/newline in sequence, or the Unicode paragraph separator character. If the iterator is already at the paragraph delimiter characters, moves to the paragraph delimiter characters for the next line. If Iter is on the last line in the buffer, which does not end in paragraph delimiters, moves to the end iterator (end of the last line), and returns False.

Forward_To_Tag_Toggle

procedure Forward_To_Tag_Toggle 
(Iter: in out Gtk_Text_Iter;
Tag: Gtk.Text_Tag.Gtk_Text_Tag := null;
Result: out Boolean);
Moves forward to the next toggle (on or off) of the Gtk.Text_Tag.Gtk_Text_Tag Tag, or to the next toggle of any tag if Tag is null. If no matching tag toggles are found, returns False, otherwise True. Does not return toggles located at Iter, only toggles after Iter. Sets Iter to the location of the toggle, or to the end of the buffer if no toggle is found. "tag": a Gtk.Text_Tag.Gtk_Text_Tag, or null

Forward_Visible_Cursor_Position

procedure Forward_Visible_Cursor_Position 
(Iter: in out Gtk_Text_Iter;
Result: out Boolean);
Moves Iter forward to the next visible cursor position. See Gtk.Text_Iter.Forward_Cursor_Position for details. Since: gtk+ 2.4

Forward_Visible_Cursor_Positions

procedure Forward_Visible_Cursor_Positions 
(Iter: in out Gtk_Text_Iter;
Count: Gint;
Result: out Boolean);
Moves up to Count visible cursor positions. See Gtk.Text_Iter.Forward_Cursor_Position for details. Since: gtk+ 2.4 "count": number of positions to move

Forward_Visible_Line

procedure Forward_Visible_Line 
(Iter: in out Gtk_Text_Iter;
Result: out Boolean);
Moves Iter to the start of the next visible line. Returns True if there was a next line to move to, and False if Iter was simply moved to the end of the buffer and is now not dereferenceable, or if Iter was already at the end of the buffer. Since: gtk+ 2.8

Forward_Visible_Lines

procedure Forward_Visible_Lines 
(Iter: in out Gtk_Text_Iter;
Count: Gint;
Result: out Boolean);
Moves Count visible lines forward, if possible (if Count would move past the start or end of the buffer, moves to the start or end of the buffer). The return value indicates whether the iterator moved onto a dereferenceable position; if the iterator didn't move, or moved onto the end iterator, then False is returned. If Count is 0, the function does nothing and returns False. If Count is negative, moves backward by 0 - Count lines. Since: gtk+ 2.8 "count": number of lines to move forward

Forward_Visible_Word_End

procedure Forward_Visible_Word_End 
(Iter: in out Gtk_Text_Iter;
Result: out Boolean);
Moves forward to the next visible word end. (If Iter is currently on a word end, moves forward to the next one after that.) Word breaks are determined by Pango and should be correct for nearly any language (if not, the correct fix would be to the Pango word break algorithms). Since: gtk+ 2.4

Forward_Visible_Word_Ends

procedure Forward_Visible_Word_Ends 
(Iter: in out Gtk_Text_Iter;
Count: Gint;
Result: out Boolean);
Calls Gtk.Text_Iter.Forward_Visible_Word_End up to Count times. Since: gtk+ 2.4 "count": number of times to move

Forward_Word_End

procedure Forward_Word_End 
(Iter: in out Gtk_Text_Iter;
Result: out Boolean);
Moves forward to the next word end. (If Iter is currently on a word end, moves forward to the next one after that.) Word breaks are determined by Pango and should be correct for nearly any language (if not, the correct fix would be to the Pango word break algorithms).

Forward_Word_Ends

procedure Forward_Word_Ends 
(Iter: in out Gtk_Text_Iter;
Count: Gint;
Result: out Boolean);
Calls Gtk.Text_Iter.Forward_Word_End up to Count times. "count": number of times to move

Get_Attributes

function Get_Attributes 
(Iter: Gtk_Text_Iter;
Values: access Gtk.Text_Attributes.Gtk_Text_Attributes) return Boolean;
Computes the effect of any tags applied to this spot in the text. The Values parameter should be initialized to the default settings you wish to use if no tags are in effect. You'd typically obtain the defaults from Gtk.Text_View.Get_Default_Attributes. gtk_text_iter_get_attributes () will modify Values, applying the effects of any tags present at Iter. If any tags affected Values, the function returns True. "values": a Gtk.Text_Attributes.Gtk_Text_Attributes to be filled in

Get_Bytes_In_Line

function Get_Bytes_In_Line 
(Iter: Gtk_Text_Iter) return Gint;

Get_Char

function Get_Char 
(Iter: Gtk_Text_Iter) return Gunichar;

Get_Chars_In_Line

function Get_Chars_In_Line 
(Iter: Gtk_Text_Iter) return Gint;

Get_Language

function Get_Language 
(Iter: Gtk_Text_Iter) return Pango.Language.Pango_Language;
A convenience wrapper around gtk_text_iter_get_attributes (), which returns the language in effect at Iter. If no tags affecting language apply to Iter, the return value is identical to that of gtk_get_default_language ().

Get_Line

function Get_Line 
(Iter: Gtk_Text_Iter) return Gint;

Set_Line

procedure Set_Line 
(Iter: in out Gtk_Text_Iter;
Line_Number: Gint);

Get_Line_Index

function Get_Line_Index 
(Iter: Gtk_Text_Iter) return Gint;

Set_Line_Index

procedure Set_Line_Index 
(Iter: in out Gtk_Text_Iter;
Byte_On_Line: Gint);

Get_Line_Offset

function Get_Line_Offset 
(Iter: Gtk_Text_Iter) return Gint;

Set_Line_Offset

procedure Set_Line_Offset 
(Iter: in out Gtk_Text_Iter;
Char_On_Line: Gint);

Get_Marks

function Get_Marks 
(Iter: Gtk_Text_Iter) return Glib.Object.Object_List.GSlist;
Returns a list of all Gtk.Text_Mark.Gtk_Text_Mark at this location. Because marks are not iterable (they don't take up any "space" in the buffer, they are just marks in between iterable locations), multiple marks can exist in the same place. The returned list is not in any meaningful order.

Get_Offset

function Get_Offset 
(Iter: Gtk_Text_Iter) return Gint;

Set_Offset

procedure Set_Offset 
(Iter: in out Gtk_Text_Iter;
Char_Offset: Gint);

Get_Pixbuf

function Get_Pixbuf 
(Iter: Gtk_Text_Iter) return Gdk.Pixbuf.Gdk_Pixbuf;
If the element at Iter is a pixbuf, the pixbuf is returned (with no new reference count added). Otherwise, null is returned.

Get_Slice

function Get_Slice 
(Iter: Gtk_Text_Iter;
The_End: Gtk_Text_Iter) return UTF8_String;
Returns the text in the given range. A "slice" is an array of characters encoded in UTF-8 format, including the Unicode "unknown" character 0xFFFC for iterable non-character elements in the buffer, such as images. Because images are encoded in the slice, byte and character offsets in the returned array will correspond to byte offsets in the text buffer. Note that 0xFFFC can occur in normal text as well, so it is not a reliable indicator that a pixbuf or widget is in the buffer. "end": iterator at end of a range

Get_Tags

function Get_Tags 
(Iter: Gtk_Text_Iter) return Gtk.Text_Tag.Text_Tag_List.GSlist;
Returns a list of tags that apply to Iter, in ascending order of priority (highest-priority tags are last). The Gtk.Text_Tag.Gtk_Text_Tag in the list don't have a reference added, but you have to free the list itself.

Get_Text

function Get_Text 
(Iter: Gtk_Text_Iter;
The_End: Gtk_Text_Iter) return UTF8_String;
Returns *text* in the given range. If the range contains non-text elements such as images, the character and byte offsets in the returned string will not correspond to character and byte offsets in the buffer. If you want offsets to correspond, see gtk_text_iter_get_slice (). "end": iterator at end of a range

Get_Toggled_Tags

function Get_Toggled_Tags 
(Iter: Gtk_Text_Iter;
Toggled_On: Boolean) return Gtk.Text_Tag.Text_Tag_List.GSlist;
Returns a list of Gtk.Text_Tag.Gtk_Text_Tag that are toggled on or off at this point. (If Toggled_On is True, the list contains tags that are toggled on.) If a tag is toggled on at Iter, then some non-empty range of characters following Iter has that tag applied to it. If a tag is toggled off, then some non-empty range following Iter does *not* have the tag applied to it. "toggled_on": True to get toggled-on tags

Get_Visible_Line_Index

function Get_Visible_Line_Index 
(Iter: Gtk_Text_Iter) return Gint;

Set_Visible_Line_Index

procedure Set_Visible_Line_Index 
(Iter: in out Gtk_Text_Iter;
Byte_On_Line: Gint);

Get_Visible_Line_Offset

function Get_Visible_Line_Offset 
(Iter: Gtk_Text_Iter) return Gint;

Set_Visible_Line_Offset

procedure Set_Visible_Line_Offset 
(Iter: in out Gtk_Text_Iter;
Char_On_Line: Gint);

Get_Visible_Slice

function Get_Visible_Slice 
(Iter: Gtk_Text_Iter;
The_End: Gtk_Text_Iter) return UTF8_String;
Like gtk_text_iter_get_slice (), but invisible text is not included. Invisible text is usually invisible because a Gtk.Text_Tag.Gtk_Text_Tag with the "invisible" attribute turned on has been applied to it. "end": iterator at end of range

Get_Visible_Text

function Get_Visible_Text 
(Iter: Gtk_Text_Iter;
The_End: Gtk_Text_Iter) return UTF8_String;
Like gtk_text_iter_get_text (), but invisible text is not included. Invisible text is usually invisible because a Gtk.Text_Tag.Gtk_Text_Tag with the "invisible" attribute turned on has been applied to it. "end": iterator at end of range

Has_Tag

function Has_Tag 
(Iter: Gtk_Text_Iter;
Tag: not null access Gtk.Text_Tag.Gtk_Text_Tag_Record'Class) return Boolean;
Returns True if Iter is within a range tagged with Tag. "tag": a Gtk.Text_Tag.Gtk_Text_Tag

In_Range

function In_Range 
(Iter: Gtk_Text_Iter;
Start: Gtk_Text_Iter;
The_End: Gtk_Text_Iter) return Boolean;
Checks whether Iter falls in the range [Start, End). Start and End must be in ascending order. "start": start of range "end": end of range

Inside_Sentence

function Inside_Sentence 
(Iter: Gtk_Text_Iter) return Boolean;
Determines whether Iter is inside a sentence (as opposed to in between two sentences, e.g. after a period and before the first letter of the next sentence). Sentence boundaries are determined by Pango and should be correct for nearly any language (if not, the correct fix would be to the Pango text boundary algorithms).

Inside_Word

function Inside_Word 
(Iter: Gtk_Text_Iter) return Boolean;
Determines whether Iter is inside a natural-language word (as opposed to say inside some whitespace). Word breaks are determined by Pango and should be correct for nearly any language (if not, the correct fix would be to the Pango word break algorithms).

Is_Cursor_Position

function Is_Cursor_Position 
(Iter: Gtk_Text_Iter) return Boolean;
See Gtk.Text_Iter.Forward_Cursor_Position or Pango_Log_Attr or pango_break for details on what a cursor position is.

Is_End

function Is_End 
(Iter: Gtk_Text_Iter) return Boolean;
Returns True if Iter is the end iterator, i.e. one past the last dereferenceable iterator in the buffer. gtk_text_iter_is_end () is the most efficient way to check whether an iterator is the end iterator.

Is_Start

function Is_Start 
(Iter: Gtk_Text_Iter) return Boolean;
Returns True if Iter is the first iterator in the buffer, that is if Iter has a character offset of 0.

Order

procedure Order 
(Iter: Gtk_Text_Iter;
Second: Gtk_Text_Iter);

Starts_Line

function Starts_Line 
(Iter: Gtk_Text_Iter) return Boolean;
Returns True if Iter begins a paragraph, i.e. if gtk_text_iter_get_line_offset () would return 0. However this function is potentially more efficient than gtk_text_iter_get_line_offset () because it doesn't have to compute the offset, it just has to see whether it's 0.

Starts_Sentence

function Starts_Sentence 
(Iter: Gtk_Text_Iter) return Boolean;
Determines whether Iter begins a sentence. Sentence boundaries are determined by Pango and should be correct for nearly any language (if not, the correct fix would be to the Pango text boundary algorithms).

Starts_Word

function Starts_Word 
(Iter: Gtk_Text_Iter) return Boolean;
Determines whether Iter begins a natural-language word. Word breaks are determined by Pango and should be correct for nearly any language (if not, the correct fix would be to the Pango word break algorithms).

Toggles_Tag

function Toggles_Tag 
(Iter: Gtk_Text_Iter;
Tag: access Gtk.Text_Tag.Gtk_Text_Tag_Record'Class) return Boolean;
This is equivalent to (gtk_text_iter_begins_tag () || gtk_text_iter_ends_tag ()), i.e. it tells you whether a range with Tag applied to it begins *or* ends at Iter. "tag": a Gtk.Text_Tag.Gtk_Text_Tag, or null

Copy

procedure Copy 
(Source: Gtk_Text_Iter;
Dest: out Gtk_Text_Iter);

Get_Char

function Get_Char 
(Iter: Gtk_Text_Iter) return Character;
Return the character immediately following Iter. If Iter is at the end of the buffer, then return ASCII.NUL. Note that this function assumes that the text is encoded in ASCII format. If this is not the case, use the Get_Char function that returns a Gunichar instead.

Iter_Or_Null

function Iter_Or_Null 
(Iter: System.Address) return System.Address;
Internal function for GtkAda

Set_Text_Iter

procedure Set_Text_Iter 
(Val: in out Glib.Values.GValue;
Iter: Gtk_Text_Iter);

Get_Text_Iter

procedure Get_Text_Iter 
(Val: Glib.Values.GValue;
Iter: out Gtk_Text_Iter);
Extract the iterator from the given GValue. Note that the iterator returned is a copy of the iterator referenced by the give GValue. Modifying the iterator returned does not modify the iterator referenced by the GValue.

Get_Slice

function Get_Slice 
(Start: Gtk_Text_Iter;
The_End: Gtk_Text_Iter) return Interfaces.C.Strings.chars_ptr;
Same as Get_Slice above, but returns the raw C string. The caller is responsible for freeing the string returned.
