Detailed Description
This is a base class for scanning dialogs. A baseclass and accessor for Scanning Dialogs.You can derive from this class and implement your own dialog. An implementation is available in kdegraphics/libkscan.
Application developers that wish to add scanning support to their program can use the static method KScanDialog::getScanDialog()
to get an instance of the user's preferred scanning dialog.
Typical usage looks like this (e.g. in a slotShowScanDialog() method):
if ( !m_scanDialog ) { m_scanDialog = KScanDialog::getScanDialog( this, "scandialog" ); if ( !m_scanDialog ) // no scanning support installed? return; connect( m_scanDialog, SIGNAL( finalImage( const QImage&, int )), SLOT( slotScanned( const QImage&, int ) )); } if ( m_scanDialog->setup() ) // only if scanner configured/available m_scanDialog->show();
This will create and show a non-modal scanning dialog. Connect to more signals if you like.
If you implement an own scan-dialog, you also have to implement a KScanDialogFactory.

Constructor & Destructor Documentation
|
Destructs the scan dialog.
|
|
Constructs the scan dialog. If you implement an own dialog, you can customize it with the usual KDialogBase flags.

Member Function Documentation
|
Creates the user's preferred scanning dialog and returns it, or 0L if no scan-support is available.

Reimplement this if you need to set up some things, before showing the dialog, e.g. to ask the user for the scanner device to use. If you return false (e.g. there is no device available or the user aborted device selection), the dialog will not be shown.

|
Returns the current id for an image. You can use that in your subclass for the signals. The id is used in the signals to let people know which preview and which text-recognition belongs to which scan.
|
|
Returns the id for the next image. You can use that in your subclass for the signals.
|
|
Informs you that an image has been previewed.
|
|
Informs you that an image has scanned.
Note, that those id's may not be properly implemented in the current libkscan.
|
|
Informs you that the image with the id The text is in the QString parameter. In the future, a compound document, using rich text will be used instead.
