我只想回答F12的钥匙,而不管谁是植被。
是否有一些容易的信号或我可以忽略的东西?
我想利用F12钥匙,把主要窗口的全插在/起飞上。

我曾尝试过,但这里我要做的是:
建立rel=“noreferer”>,并确保其context(有Context(<>t/code)>,<>t>:AppShortcut<>。
shortcut = new QShortcut(QKeySequence(Qt::Key_F12), parent);
shortcut->setContext(Qt::ApplicationShortcut);
然后,你只需要将一个位置与QShortcut:激活()信号。
为<代码>确定简短的背景 Qt:ApplicationShortcut 存在严重缺陷。 它不会在模式方言中工作。 因此,如果你希望全程适用全程适用,那么你就必须超越<条码>(指)代码>方法。 另一种办法是为申请标安装活动过滤器,但我怀疑速度较慢,需要略微增加代码。 缩略语
class MyApplication : public QApplication
{
// TODO: constructor etc.
protected:
bool MyApplication::notify(QObject *receiver, QEvent *event) override
{
if (event->type() == QEvent::KeyPress)
{
auto keyEvent = static_cast<QKeyEvent*>(event);
if (keyEvent->key() == Qt::Key_F12 && keyEvent->modifiers() == Qt::NoModifiers)
{
// TODO: do what you need to do
return true;
}
}
return QApplication::notify(receiver, event);
}
}
如果你有一个“中央植被”,而所有其他植被都是儿童,那么你就可以简单地确定,作为QShortcut的植被理由。
(Python, qt5)
self.centralwidget = QtWidgets.QWidget(MainWindow)
QtWidgets.QShortcut(QtGui.QKeySequence("F12"), self.centralwidget, self.goFullScreen)
我补充说,这只是一个答案,因为捷径旗:Qt.ApplicationShortcut
对我没有作用。
