qt 中 nofocus tabfocus clickouce strongfocus wheelfocus 的区别

[project15]

现在我用到的只是
nofocus 和strongfocus
nofocus是永远都不会获取焦点
strongfocus是激活它的时候就有焦点
其他几个是什么意思？
在什么情况下使用？

有顾名思义的冲动……

QWidget::FocusPolicy
This enum type defines the various policies a widget can have with respect to acquiring keyboard focus.
QWidget::TabFocus - the widget accepts focus by tabbing.
QWidget::ClickFocus - the widget accepts focus by clicking.
QWidget::StrongFocus - the widget accepts focus by both tabbing and clicking.
QWidget::WheelFocus - like StrongFocus plus the widget accepts focus by using the mouse wheel.
QWidget::NoFocus - the widget does not accept focus.

楼主看看mannual,然后自己试验一下,就清楚了,学QT都是这样积累的

这是与焦点策略对应的focus motion


Focus motion
The customs which have evolved for directing keyboard focus to a particular widget are these:
The user presses Tab (or Shift+Tab) (or sometimes Enter).
The user clicks a widget.
The user presses a keyboard shortcut.
The user uses the mouse wheel.
The user moves the focus to a window, and the application must determine which widget within the window should get the focus.
Each of these motion mechanisms is different, and different types of widgets receive focus in only some of them. We'll cover each of them in turn.

QWidget::StrongFocus - the widget accepts focus by both tabbing and clicking.
