Qt 4.8 Hide cursor in fullscreen

2019-06-17 06:35发布

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: -

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);
