快捷鍵不被觸發

Question

這是我的類聲明：

class Browser : public QWidget {  
    Q_OBJECT 
    public: 
     Browser(QWidget *parent = 0); 
     QStringList loadSettings(QString settings_file); 
    private slots: 
     void toggleFullscreen();    
    private:  
     void createActions(); 
     QAction *aToggleFullscreen;    
}; 

而且relevand定義：

void Browser::toggleFullscreen() { 
    out << "fullscreen!" << endl; 
} 
void Browser::createActions() { 
    aToggleFullscreen = new QAction(this); 
    aToggleFullscreen->setShortcut(tr("F11"));  
    connect(aToggleFullscreen, SIGNAL(triggered()), this, SLOT(toggleFullscreen()));  
} 

我打電話從Browser::BrowsercreateActions()。

我沒有任何運行時警告，該插槽不存在等，但仍然沒有觸發如果我擊中F11。

我也試過：

aToggleFullscreen->setShortcut(QString("F11")); 

這是什麼錯我的代碼？

您忘了實際將您的操作添加到瀏覽器，因此它永遠不會被觸發。這應該工作：

void Browser::createActions() { 
    aToggleFullscreen = new QAction(this); 
    aToggleFullscreen->setShortcut(tr("F11"));  
    connect(aToggleFullscreen, SIGNAL(triggered()), this, SLOT(toggleFullscreen())); 
    addAction(aToggleFullscreen);  
}
