Hide cursor in fullscreen mode using Qt 4.8?

Question

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 ever

Answer 1

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);
