References KisTool::currentNode(), and KisNode::setDirty().

◆ beginPrimaryAction()

void KisToolGradient::beginPrimaryAction ( KoPointerEvent * event )

overridevirtual

Called by KisToolProxy when a primary action for the tool is started. The event stores the original event that started the stroke. The event is accepted by default. If the tool decides to ignore this particular action (e.g. when the node is not editable), it should call event->ignore(). Then no further continuePrimaryAction() or endPrimaryAction() will be called until the next user action.

Reimplemented from KisTool.

}

◆ continuePrimaryAction()

void KisToolGradient::continuePrimaryAction ( KoPointerEvent * event )

overridevirtual

Called by KisToolProxy when the primary action is in progress of pointer movement. If the tool has ignored the event in beginPrimaryAction(), this method will not be called.

TODO: The gradient tool is still not in strokes, so the end of its action can call processEvent(), which would result in nested event handler calls. Please uncomment this line when the tool is ported to strokes.
