Detailed Description

A decorator which adds drag-support to widgets.

This is a decorator using an event filter to implement drag-support in widgets. You must override the virtual method dragObject() to specify the QDrag to be used.

Member Function Documentation

decoratedWidget()

QWidget * KDragWidgetDecoratorBase::decoratedWidget ( ) const

protected

Returns

the widget this decorator is attached to

Definition at line 68 of file kdragwidgetdecorator.cpp.

dragObject()

QDrag * KDragWidgetDecoratorBase::dragObject ( )

protectedvirtual

Reimplement this and return the QDrag object that should be used for the drag.

Remember to give it "decoratedWidget()" as parent.

Default implementation returns a null pointer, so that no drag is initiated.

Definition at line 73 of file kdragwidgetdecorator.cpp.

eventFilter()

bool KDragWidgetDecoratorBase::eventFilter ( QObject * watched, QEvent * event )

overrideprotectedvirtual

Reimplemented to add drag-support.

Reimplemented from QObject.

Definition at line 43 of file kdragwidgetdecorator.cpp.

isDragEnabled()

bool KDragWidgetDecoratorBase::isDragEnabled

(

)

const

Returns

if drag support is enabled or not.

Definition at line 33 of file kdragwidgetdecorator.cpp.

setDragEnabled()

void KDragWidgetDecoratorBase::setDragEnabled

(

bool

enable

)

Enables/disables drag-support.

Default is enabled.

Definition at line 38 of file kdragwidgetdecorator.cpp.

startDrag()

void KDragWidgetDecoratorBase::startDrag ( )

protectedvirtual

Starts a drag (Copy by default) using dragObject()
