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 every time: 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();
}
}
I want to hide the cursor on fullscreen ...
You could set the cursor to be the blank cursor:
widget->setCursor(Qt::BlankCursor);
Also, as the docs state:
Some underlying window implementations will reset the cursor if it leaves a widget even if the mouse is grabbed. If you want to have a cursor set for all widgets, even when outside the window, consider
QApplication::setOverrideCursor()
.
So you can call:
QApplication::setOverrideCursor(Qt::BlankCursor);
