* KWin client button tooltip support module

|
* Uses portions of QToolTip code
|
|
* Copyright (c) TrollTech AS
|
|
*
|
|
* Since Qt installs its own internal event filter when using
|
|
* a QToolTip, kwin doesn't obtain the necessary events and hence
|
|
* focus problems and loss of window frames occur if they are used
|
|
* for kwin styles. Thus, this small class implements a bare subset
|
|
* of QToolTip designed especially for kwin client buttons without
|
|
* installing any event filters that confuse kwin.
|
|
*
|
|
* For all normal clients, simply use the KWinButton class instead
|
|
* of QButton, which will use a KWinToolTip internally. Other clients
|
|
* which rely on QToolButton or QWidget for client buttons may use the
|
|
* KWinToolButton and KWinWidgetButton classes to automatically take
|
|
* care of tooltips.
