[solved] minimize event

zidom

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&#40;&#41;;

}
@
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&#40;&#41;;

}@
i received some errors

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.

[quote author="zidom" date="1348914755"]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);}
}@

@if (event->type()==QEvent::WindowStateChange && isMinimized())
{

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))

Use showNormal() instead.

zidom

bq. This example may help you:
http://doc.qt.digia.com/4.7-snapshot/desktop-systray.html
(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
