class KScanDialog |
|
|
This is a base class 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 ); if ( !m_scanDialog ) // no scanning support installed? return; 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.

Constructs the scan dialog. If you implement an own dialog, you can customize it with the usual KPageDialog flags.
dialogFace - The KPageDialog.FaceType buttonMask - An ORed mask of all buttons (see KDialog.ButtonCode) parent - The QWidget's parent, or 0 See also KPageDialog |
|
Informs you that an image has scanned. id is the same as in the preview() signal, if this image had been previewed before. Note, that those id's may not be properly implemented in the current libkscan. img - the image id - the image's id |
|
Creates the user's preferred scanning dialog and returns it, or 0L if no scan-support is available. Pass a suitable parent widget, if you like. If you don't you have to 'delete' the returned pointer yourself. parent - the QWidget's parent, or 0 Returns the KScanDialog, or 0 if the function failed |

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 current id for the image See also nextId See also finalImage See also preview See also textRecognized |
|
Returns the id for the next image. You can use that in your subclass for the signals. Returns the id for the next image See also id See also finalImage See also preview See also textRecognized

Informs you that an image has been previewed. img - the image id - the image's id |
|
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 true by default. |

Informs you that the image with the id id has been run through text-recognition. The text is in the QString parameter. In the future, a compound document, using rich text will be used instead.
text - the text that has been recognized id - the id of the image |
