Property Documentation

autoMaximizeThreshold : int

This property defines a threshold for auto maximizing widgets The auto maximize threshold is only available as part of Qt for Windows CE.

This property defines a threshold for the size of a window as a percentage of the screen size. If the minimum size hint of a window exceeds the threshold, calling show() will cause the window to be maximized automatically.

Setting the threshold to 100 or greater means that the widget will always be maximized. Alternatively, setting the threshold to 50 means that the widget will be maximized only if the vertical minimum size hint is at least 50% of the vertical screen size.

Setting the threshold to -1 disables the feature.

On Windows CE the default is -1 (i.e., it is disabled). On Windows Mobile the default is 40.

This property was introduced in Qt 4.4.
