[solved] minimize event

[zidom]

[Solved]
hi i wrote a program i want to hide and sent it to tray when its minimized i used code below
@bool myclass::event(QEvent *event)
{
if (event->type()==QEvent::WindowStateChange && isMinimized())
{
hide();
event->ignore();
}
else{
return QMainWindow::event(event);}
}@
but this happens
before minimize
!http://dl.2rialy.ir/ZiDoM-Ups/91/before.JPG(before)!
after minimize
!http://dl.2rialy.ir/ZiDoM-Ups/91/after.JPG(after)!

i dont know why this happens because when i use this code
@
void myclass::closeEvent(QCloseEvent *event)
{
hide();
event->ignore();
}
@
it works fine

[DerManu]

What happens when you let the event propagate to the mainwindow in both cases? (I.e. remove the event->ignore(); and the else branch)

[zidom]

no difference it same as now i test that before

[lgeyer]

Well, if you minimize a window it is automatically hidden (that's why you minimize it in the first place).

If you are talking about hiding the taskbar entry see "this":http://qt-project.org/forums/viewthread/8902 thread.

those dont work to

[lgeyer]

How much use do you think can we make of "those dont work to"?

[zidom]

sorry but i thought its obvious i meant that the link that you suggest the codes in that link didn't work
sorry because of bad explaining

[lgeyer]

So, what have you tried? How does the code look like? What did you expect? And what is it actually doing?

[zidom]

I tried this
@
int main(int argc, char *argv[])
{
QApplication application(argc, argv);

QWidget widget;
QMainWindow mainWindow(&widget);

mainWindow.show();

return application.exec();

}
@
but it doesn't hide the taskbar icon hides the window to
and when i tried this
@int main(int argc, char *argv[])
{
QApplication application(argc, argv);

QMainWindow mainWindow;

mainWindow.show();

ShowWindow(mainWindow.winId(), SW_HIDE);
SetWindowLong(mainWindow.winId(), GWL_EXSTYLE, GetWindowLong(mainWindow.winId(), GWL_EXSTYLE) | ~WS_EX_APPWINDOW);
ShowWindow(mainWindow.winId(), SW_SHOW);

return application.exec();

}@
i received some errors

[lgeyer]

Snippet #1 does not show a taskbar icon, and so does setting the Qt::Tool window flag - at least for me.
@
void MainWindow::changeEvent(QEvent *event)
{
if (event->type() == QEvent::WindowStateChange)
{
if (isMinimized() == true)
setWindowFlags(windowFlags() | Qt::Tool);
else
setWindowFlags(windowFlags() & ~Qt::Tool);
}

return QMainWindow::changeEvent(event);

}@

Using ~WS_EX_APPWINDOW does, as mentioned in the linked thread, not work properly.

Hi mahdi
Thanks that worked but i don't understand why i should hide then show then hide again
im iranian like you :D

[zidom]

bq.

 void MainWindow::changeEvent(QEvent *event)
{
    if (event->type() == QEvent::WindowStateChange)
    {
        if (isMinimized() == true)
            setWindowFlags(windowFlags() | Qt::Tool);
        else
            setWindowFlags(windowFlags() & ~Qt::Tool);
    }
 
    return QMainWindow::changeEvent(event);
}

I used that it works for hiding but when i want to show the form again

void myclass::trayicon_click(QSystemTrayIcon::ActivationReason reason)
{
    if(reason==QSystemTrayIcon::Trigger)
    {
        show();
    }
}

it looks like this when i show the form !http://dl.2rialy.ir/ZiDoM-Ups/91/after.JPG(show)!

This example may help you:
http://doc.qt.digia.com/4.7-snapshot/desktop-systray.html
(void Window::closeEvent(QCloseEvent *event))

[lgeyer]

Use showNormal() instead.

bq. This example may help you:

(void Window::closeEvent(QCloseEvent *event))

I already saw that but that doesn't help me by the way thank

bq. Use showNormal() instead.

thanks a lot that worked again thanks for following this article and helping me
