|
|
This class can be used to implement demand-loading of config pages.
|
|
In order to avoid the potentially heavy and unneccessary creation
|
|
of a config page that might not be needed, this class can be used
|
|
to delay the config page creation until the user explicitly asks
|
|
for it.
|
|
|
|
A typical case looks like this:
|
|
@code
|
|
#define GLOBALDOC_OPTIONS 1
|
|
#define PROJECTDOC_OPTIONS 2
|
|
|
|
_configProxy = new ConfigWidgetProxy( core() );
|
|
_configProxy->createGlobalConfigPage( i18n("My Part"), GLOBALDOC_OPTIONS, info()->icon() );
|
|
_configProxy->createProjectConfigPage( i18n("My Part"), PROJECTDOC_OPTIONS, info()->icon() );
|
|
connect( _configProxy, TQ_SIGNAL(insertConfigWidget(const TQObject*, TQWidget*, unsigned int )),
|
|
this, TQ_SLOT(insertConfigWidget(const TQObject*, TQWidget*, unsigned int )) );
|
|
|
|
...
|
|
...
|
|
|
|
void MyPart::insertConfigWidget( TQObject const * dlg, TQWidget * page, unsigned int pagenumber )
|
|
{
|
|
if ( pagenumber == PROJECTDOC_OPTIONS ) {
|
|
MyPartGlobalSettings * w = new MyPartGlobalSettings( this, page );
|
|
connect( dlg, TQ_SIGNAL(okClicked()), w, TQ_SLOT(slotAccept()) );
|
|
} else if ( pagenumber == PROJECTDOC_OPTIONS ) {
|
|
MyPartProjectSettings * w = new MyPartProjectSettings( this, page );
|
|
connect( dlg, TQ_SIGNAL(okClicked()), w, TQ_SLOT(slotAccept()) );
|
|
}
|
|
}
|
|
@endcode
|
|
|
|
Note that this replaces the functionality of typical KDevCore::configWidget() and
|
|
KDevCore::projectConfigWidget() slots.
