Package: Progress_Bar

Description

package Gtk.Progress_Bar is

The Gtk.Progress_Bar.Gtk_Progress_Bar is typically used to display the progress of a long running operation. It provides a visual clue that processing is underway. The Gtk.Progress_Bar.Gtk_Progress_Bar can be used in two different modes: percentage mode and activity mode.

When an application can determine how much work needs to take place (e.g. read a fixed number of bytes from a file) and can monitor its progress, it can use the Gtk.Progress_Bar.Gtk_Progress_Bar in percentage mode and the user sees a growing bar indicating the percentage of the work that has been completed. In this mode, the application is required to call Gtk.Progress_Bar.Set_Fraction periodically to update the progress bar.

When an application has no accurate way of knowing the amount of work to do, it can use the Gtk.Progress_Bar.Gtk_Progress_Bar in activity mode, which shows activity by a block moving back and forth within the progress area. In this mode, the application is required to call Gtk.Progress_Bar.Pulse periodically to update the progress bar.

There is quite a bit of flexibility provided to control the appearance of the Gtk.Progress_Bar.Gtk_Progress_Bar. Functions are provided to control the orientation of the bar, optional text can be displayed along with the bar, and the step size used in activity mode can be set.

Types

Gtk_Progress_Bar

type Gtk_Progress_Bar is access all Gtk_Progress_Bar_Record'Class;

Constants & Global variables

Ellipsize_Property (Pango.Layout.Property_Pango_Ellipsize_Mode)

Ellipsize_Property : constant Pango.Layout.Property_Pango_Ellipsize_Mode;
Type: Pango.Layout.Pango_Ellipsize_Mode The preferred place to ellipsize the string, if the progress bar does not have enough room to display the entire string, specified as a Pango.Layout.Pango_Ellipsize_Mode. Note that setting this property to a value other than Pango.Layout.Ellipsize_None has the side-effect that the progress bar requests only enough space to display the ellipsis ("..."). Another means to set a progress bar's width is Gtk.Widget.Set_Size_Request.

Fraction_Property (Glib.Properties.Property_Double)

Fraction_Property : constant Glib.Properties.Property_Double;
Type: Gdouble

Pulse_Step_Property (Glib.Properties.Property_Double)

Pulse_Step_Property : constant Glib.Properties.Property_Double;
Type: Gdouble

Show_Text_Property (Glib.Properties.Property_Boolean)

Show_Text_Property : constant Glib.Properties.Property_Boolean;
Sets whether the progress bar will show text superimposed over the bar. The shown text is either the value of the Gtk.Progress_Bar.Gtk_Progress_Bar:text property or, if that is null, the Gtk.Progress_Bar.Gtk_Progress_Bar:fraction value, as a percentage. To make a progress bar that is styled and sized suitably for containing text (even if the actual text is blank), set Gtk.Progress_Bar.Gtk_Progress_Bar:show-text to True and Gtk.Progress_Bar.Gtk_Progress_Bar:text to the empty string (not null).

Subprograms & Entries

Gtk_New

procedure Gtk_New 
(Progress_Bar: out Gtk_Progress_Bar);

Initialize

procedure Initialize 
(Progress_Bar: not null access Gtk_Progress_Bar_Record'Class);

Gtk_Progress_Bar_New

function Gtk_Progress_Bar_New return Gtk_Progress_Bar;

Get_Type

function Get_Type return Glib.GType;

Get_Ellipsize

function Get_Ellipsize 
(Progress_Bar: not null access Gtk_Progress_Bar_Record) return Pango.Layout.Pango_Ellipsize_Mode;
Returns the ellipsizing position of the progress bar. See Gtk.Progress_Bar.Set_Ellipsize. Since: gtk+ 2.6

Set_Ellipsize

procedure Set_Ellipsize 
(Progress_Bar: not null access Gtk_Progress_Bar_Record;
Mode: Pango.Layout.Pango_Ellipsize_Mode);
Sets the mode used to ellipsize (add an ellipsis: "...") the text if there is not enough space to render the entire string. Since: gtk+ 2.6 "mode": a Pango.Layout.Pango_Ellipsize_Mode

Get_Fraction

function Get_Fraction 
(Progress_Bar: not null access Gtk_Progress_Bar_Record) return Gdouble;
Returns the current fraction of the task that's been completed.

Set_Fraction

procedure Set_Fraction 
(Progress_Bar: not null access Gtk_Progress_Bar_Record;
Fraction: Gdouble);
Causes the progress bar to "fill in" the given fraction of the bar. The fraction should be between 0.0 and 1.0, inclusive. "fraction": fraction of the task that's been completed

Get_Inverted

function Get_Inverted 
(Progress_Bar: not null access Gtk_Progress_Bar_Record) return Boolean;
Gets the value set by Gtk.Progress_Bar.Set_Inverted.

Set_Inverted

procedure Set_Inverted 
(Progress_Bar: not null access Gtk_Progress_Bar_Record;
Inverted: Boolean);
Progress bars normally grow from top to bottom or left to right. Inverted progress bars grow in the opposite direction. "inverted": True to invert the progress bar

Get_Pulse_Step

function Get_Pulse_Step 
(Progress_Bar: not null access Gtk_Progress_Bar_Record) return Gdouble;
Retrieves the pulse step set with Gtk.Progress_Bar.Set_Pulse_Step.

Set_Pulse_Step

procedure Set_Pulse_Step 
(Progress_Bar: not null access Gtk_Progress_Bar_Record;
Fraction: Gdouble);
Sets the fraction of total progress bar length to move the bouncing block for each call to Gtk.Progress_Bar.Pulse. "fraction": fraction between 0.0 and 1.0

Get_Show_Text

function Get_Show_Text 
(Progress_Bar: not null access Gtk_Progress_Bar_Record) return Boolean;
Gets the value of the Gtk.Progress_Bar.Gtk_Progress_Bar:show-text property. See Gtk.Progress_Bar.Set_Show_Text. Since: gtk+ 3.0

Set_Show_Text

procedure Set_Show_Text 
(Progress_Bar: not null access Gtk_Progress_Bar_Record;
Show_Text: Boolean);
Sets whether the progress bar will show text superimposed over the bar. The shown text is either the value of the Gtk.Progress_Bar.Gtk_Progress_Bar:text property or, if that is null, the Gtk.Progress_Bar.Gtk_Progress_Bar:fraction value, as a percentage. To make a progress bar that is styled and sized suitably for containing text (even if the actual text is blank), set Gtk.Progress_Bar.Gtk_Progress_Bar:show-text to True and Gtk.Progress_Bar.Gtk_Progress_Bar:text to the empty string (not null). Since: gtk+ 3.0 "show_text": whether to show superimposed text

Get_Text

function Get_Text 
(Progress_Bar: not null access Gtk_Progress_Bar_Record) return UTF8_String;
Retrieves the text displayed superimposed on the progress bar, if any, otherwise null. The return value is a reference to the text, not a copy of it, so will become invalid if you change the text in the progress bar.

Set_Text

procedure Set_Text 
(Progress_Bar: not null access Gtk_Progress_Bar_Record;
Text: UTF8_String := "");
Causes the given Text to appear superimposed on the progress bar. If Text is null and Gtk.Progress_Bar.Gtk_Progress_Bar:show-text is True, the current value of Gtk.Progress_Bar.Gtk_Progress_Bar:fraction will be displayed as a percentage. If Text is non-null and Gtk.Progress_Bar.Gtk_Progress_Bar:show-text is True, the text will be displayed. In this case, it will not display the progress percentage. If Text is the empty string, the progress bar will still be styled and sized suitably for containing text, as long as Gtk.Progress_Bar.Gtk_Progress_Bar:show-text is True. "text": a UTF-8 string, or null

Pulse

procedure Pulse 
(Progress_Bar: not null access Gtk_Progress_Bar_Record);
Indicates that some progress has been made, but you don't know how much. Causes the progress bar to enter "activity mode," where a block bounces back and forth. Each call to Gtk.Progress_Bar.Pulse causes the block to move by a little bit (the amount of movement per pulse is determined by Gtk.Progress_Bar.Set_Pulse_Step).

Get_Orientation

function Get_Orientation 
(Self: not null access Gtk_Progress_Bar_Record) return Gtk.Enums.Gtk_Orientation;

Set_Orientation

procedure Set_Orientation 
(Self: not null access Gtk_Progress_Bar_Record;
Orientation: Gtk.Enums.Gtk_Orientation);
