QFocusFrame ¶

概要 ¶

详细描述 ¶

Normally an application will not need to create its own QFocusFrame as QStyle will handle this detail for you. A style writer can optionally use a QFocusFrame to have a focus area outside of the widget’s paintable geometry. In this way space need not be reserved for the widget to have focus but only set on a QWidget with setWidget . It is, however, legal to create your own QFocusFrame on a custom widget and set its geometry manually via setGeometry 但不会自动放置，当聚焦 Widget 改变大小或放置时。

class QFocusFrame ( [ parent=None ] ) ¶

param parent

QWidget

构造 QFocusFrame .

聚焦框架不会监控 parent for updates but rather can be placed manually or by using setWidget . A QFocusFrame sets WA_NoChildEventsForParent attribute; as a result the parent will not receive a ChildAdded event, this will make it possible to manually set the geometry of the QFocusFrame inside of a QSplitter or other child event monitoring widget.
