* QWidget::isFullScreen() may reflect the new or the old state
|
|
* depending on how the action was triggered (by the application or
|
|
* from the window manager). Also don't try to track the window state
|
|
* yourself. Rely on this action's state (isChecked()) instead.
|
|
*
|
|
* Important: If you need to set/change the fullscreen state manually,
|
|
* use KToggleFullScreenAction::setFullScreen() or a similar function,
|
|
* do not call directly the slot connected to the toggled() signal. The slot
|
|
* still needs to explicitly set the window state though.
|
|
*
|
|
* Note: Do NOT use QWidget::showFullScreen() or QWidget::showNormal().
|
|
* They have several side-effects besides just switching the fullscreen
|
|
* state (for example, showNormal() resets all window states, not just
|
|
* fullscreen). Use the KToggleFullScreenAction::setFullScreen() helper function.
