C++ (Cpp) DeleteDragPainter Examples

Example #1

void
UndoWidget::HandleMouseUp
	(
	const JPoint&			pt,
	const JXMouseButton		button,
	const JXButtonStates&	buttonStates,
	const JXKeyModifiers&	modifiers
	)
{
	JPainter* p = NULL;

	// Make sure that the left button is pressed,
	// and that a drag painter exists
	if (button == kJXLeftButton && GetDragPainter(&p))
		{
		// Erase the last line that was drawn
		p->Line(itsStartPt, itsPrevPt);

		// Delete the drag painter
		DeleteDragPainter();

		// Add this set of points to our JArray
		itsPoints->AppendElement(itsStartPt);
		itsPoints->AppendElement(itsPrevPt);

		// Create the undo object to undo the addition of this line

		UndoLine* undo = new UndoLine(this);
		assert(undo != NULL);
		NewUndo(undo);

		// Tell the widget to redraw itself
		Refresh();
		}
}
