How to steal focus on simple mouse click at an empty space of the window?

[Leon]

So i have a spinbox which is connected with editingfinished..
so i want the void editing finished to be called if you click with the mouse at an empty space at that window.. How to accomplish that?

If I understand you correctly, you can inherit from QWidget and override the "event":http://qt-project.org/doc/qwidget.html#mousePressEvent :

@
class MyClass: public QWidget {
protected:
void mousePressEvent(QMouseEvent *event) {
// some code
}
}
@

In addition to the above code you need to emit a signal inside mousePressEvent() like

@void MyClass::mousePressEvent(QMouseEvent *event)
{

if (event->button() == Qt::LeftButton)
    emit clicked();

}@

where clicked() is a signal declared in .h file eg

@class MyClass : public QWidget
{
Q_OBJECT
public:
//some declaration ... ...

signals:
void clicked();

private:
Ui::MyClass *ui;

};@

and you need to connect signal & slots like

@connect(this,SIGNAL(clicked()),SLOT(editingfinished()));@
