Detailed Description

Tool button with a menu at the side.

Copyright (c) 2007, Matevž Jekovec, Canorus development team All Rights Reserved. See AUTHORS for a complete list of authors.

Licensed under the GNU GENERAL PUBLIC LICENSE. See COPYING for details.

This widget looks like a button with a small dropdown arrow at the side which opens a custom widget (also called "buttons") where user chooses from various actions then. When the element is selected, the action's icon is replaced with the previous icon on the toolbutton and a signal toggled(bool checked, int id) is emitted.

Remarks
Subclasses must call setPopupWidget() on the floating widget once it's initialized. Showing/hiding is handled in CAToolButton. Subclasses can connect to the show() or hide() signals, which are emitted just before showing or hiding the widget.

◆ calculateTopLeft()

QPoint CAToolButton::calculateTopLeft ( QSize  size)
protected

This function returns the absolute top-left coordinate where the popup menu or whichever widget should appear when the users clicks on the button.

The problem is that the popup widget should be completely visible in whichever part of the screen the toolbutton is located. Popup widget should also always stick to one corner of the toolbutton.

Parameter size is the width and height needed for the whole widget to appear.
