QMainWindow Class Reference
[QtGui module]

unifiedTitleAndToolBarOnMac : bool

This property holds whether the window uses the unified title and toolbar look on Mac OS X.

This property is false by default and only has any effect on Mac OS X 10.4 or higher.

If set to true, then the top toolbar area is replaced with a Carbon HIToolbar or a Cocoa NSToolbar (depending on whether Qt was built with Carbon or Cocoa). All toolbars in the top toolbar area and any toolbars added afterwards are moved to that. This means a couple of things.

• QToolBars in this toolbar area are not movable and you cannot drag other toolbars to it
• Toolbar breaks are not respected or preserved
• Any custom widgets in the toolbar will not be shown if the toolbar becomes too small (only actions will be shown)
• Before Qt 4.5, if you called showFullScreen() on the main window, the QToolbar would disappear since it is considered to be part of the title bar. Qt 4.5 and up will now work around this by pulling the toolbars out and back into the regular toolbar and vice versa when you swap out. However, a good practice would be that turning off the unified toolbar before you call showFullScreen() and restoring it after you call showNormal().

Setting this back to false will remove these restrictions.

The Qt::WA_MacBrushedMetal attribute takes precedence over this property.

This property was introduced in Qt 4.3.
