Mainwindow winks

[sophister]

Hi to all:
I use the following codes to hide my mainwindow when the mouse leave it, and show it when the mouse enter it. but when the mouse enter the mainwindow, it wrinks all the time.

//mouse leave
void EasyGo::leaveEvent(QEvent *)
{
    //如果主界面靠近屏幕上边缘，则进入上边缘以上
    QPoint leftTop = pos();
    if(leftTop.y() < 6)
    {
        move(leftTop.x(), -frameGeometry().height() + 6);
        return;
    }
}
 
//mouse enter
void EasyGo::enterEvent(QEvent *)
{
    QPoint leftTop = pos();
    if(leftTop.y() < 0)
    {
        move(leftTop.x(), 0);
        update();
        return;
    }
}

//mouse leave
void EasyGo::leaveEvent(QEvent *)
{
    //如果主界面靠近屏幕上边缘，则进入上边缘以上
    QPoint leftTop = pos();
    if(leftTop.y() < 6)
    {
        move(leftTop.x(), -frameGeometry().height() + 6);
        return;
    }
}

//mouse enter
void EasyGo::enterEvent(QEvent *)
{
    QPoint leftTop = pos();
    if(leftTop.y() < 0)
    {
        move(leftTop.x(), 0);
        update();
        return;
    }
}

To copy to clipboard, switch view to plain text mode 

any idea appreciated.

Wouldnt it be better if you hide/show you widget on mouse events in the parent window ?
I mean once you hide you window on mouse leave, how do you expect to get enter event ?

I guess it will be better if you trap some area in parent widget and show/hide your window accordingly.

[sophister]

yeah, but, this is my top level window, so it has no parent window.
Thanks

You could set opacity to zero... but I don't know if that uses more cpu/ram....?

[sophister]

yeah, it does use more cpu and arm.
thanks!!

So.. whats your solution?

[aamer4yu]

I guess changing opacity on enter and leave event would be better as it happens in Winamp.
If you try to hide the window, how do you expect to bring it back ? You will need to monitor the mouse events on the desktop and then bring back your application, which I think would be heavy task for a simple application.

I have to setMaxmunSize and minimunsize of the window when the mouse enters or leaves the window, i.e, I when the mouse leaves the window, set the window to a smaller one, and set it back to the original size when the mouse enters again.
But, it's not what I want to use……
