Detailed Description

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;
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();
KScanDialog::getScanDialog
static KScanDialog * getScanDialog(QWidget *parent=0)
Creates the user's preferred scanning dialog and returns it, or 0L if no scan-support is available.
Definition: kscan.cpp:38
KScanDialog::finalImage
void finalImage(const QImage &img, int id)
Informs you that an image has scanned.

This will create and show a non-modal scanning dialog. Connect to more signals if you like.

Constructor & Destructor Documentation

◆ ~KScanDialog()

KScanDialog::~KScanDialog ( )

Destructs the scan dialog.

Definition at line 55 of file kscan.cpp.

◆ KScanDialog()

KScanDialog::KScanDialog ( int  dialogFace = Tabbed,
int  buttonMask = Close|Help,
QWidget *  parent = 0 
)
explicitprotected

Constructs the scan dialog.

If you implement an own dialog, you can customize it with the usual KPageDialog flags.

Parameters
dialogFaceThe KPageDialog::FaceType
buttonMaskAn ORed mask of all buttons (see KDialog::ButtonCode)
parentThe QWidget's parent, or 0

KPageDialog

Definition at line 44 of file kscan.cpp.

Member Function Documentation

◆ finalImage

void KScanDialog::finalImage ( const QImage &  img,
int  id 
)
signal

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.

Parameters
imgthe image
idthe image's id

◆ getScanDialog()

KScanDialog * KScanDialog::getScanDialog ( QWidget *  parent = 0)
static

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.

Parameters
parentthe QWidget's parent, or 0
Returns
the KScanDialog, or 0 if the function failed

Definition at line 38 of file kscan.cpp.

◆ id()

int KScanDialog::id ( ) const
protected

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
finalImage
preview
textRecognized

Definition at line 60 of file kscan.cpp.

◆ nextId()

int KScanDialog::nextId ( )
protected

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
finalImage
preview
textRecognized

Definition at line 65 of file kscan.cpp.

◆ preview

void KScanDialog::preview ( const QImage &  img,
int  id 
)
signal

Informs you that an image has been previewed.

Parameters
imgthe image
idthe image's id

◆ setup()

bool KScanDialog::setup ( )
virtual

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.

Definition at line 70 of file kscan.cpp.

◆ textRecognized

void KScanDialog::textRecognized ( const QString &  text,
int  id 
)
signal

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.

Parameters
textthe text that has been recognized
idthe id of the image
