[pengliang(彭亮)]

Hi All:

     Please see the snippet bellow. (I want to minimizied the windows and capture the screen, but application capture screen before the window was fully minimized.) why? Can anybody tell me why? Or give me some ideas.

Thanks. Have a nice day!

 

------------------   snippet ------------------------------------------------

        if(setHideWnd == true) {

            windowHideShow();

            //QTimer::singleShot(200,this,SLOT(capture_screen()));

            // while(this->isVisible())

            while(this->isHidden())

            {

                //qApp->processEvents();

                capture_screen();

                windowHideShow();

            }

        } else {

            capture_screen();

        }

 

 

void MainWindow::windowHideShow()

 {

    if(isHideWnd == true)

    {

        //showNormal();

        this->show();

        isHideWnd = false;

        activateWindow();

    } else {

        //showMinimized();

        this->hide();

        hide();

        isHideWnd = true;

    }

}
