qt设计师在状态栏不可以加入widget吗？ [复制链接]

void QStatusBar::addWidget ( QWidget * widget, int stretch = 0 )
Adds the given widget to this status bar, reparenting the widget if it isn't already a child of this QStatusBar object. The stretch parameter is used to compute a suitable size for the given widget as the status bar grows and shrinks. The default stretch factor is 0, i.e giving the widget a minimum of space.
The widget is located to the far left of the first permanent widget (see addPermanentWidget()) and may be obscured by temporary messages.
