I'm in a ArchLinux with OpenBox and I want to hide the cursor on fullscreen inside a Qt 4.8 application. I am aware about some other question about it but no one works everytime: sometimes the cursor is hiding, sometimes not. I didn't managed to understand exactly when the problem occurs but I think that maybe is it related with the screensaver because if I test my application just after the computer is restarted the mouse cursor is no visible (and it is what I want) but if I test this feature during the day the mouse cursor is still visible in fullscreen.
This is my code:
void MainWindow::toggleFullScreen()
{
if(!this->isFullScreen())
{
this->showFullScreen();
#ifdef Q_WS_QWS
QWSServer::setCursorVisible( false );
#endif
}
else
{
this->showNormal();
}
}
There is a program named unclutter that hides the mouse pointer. Here's an ArchLinux package:

I currently use it on an embedded system for hiding the mouse cursor on a touchscreen.
You could set the cursor to be the blank cursor: -
widget->setCursor(Qt::BlankCursor);
Also, as the docs state: -
So you can call:-
