Im trying to use a gif to show that its loading.Then Function only runs once I press on a button in the GUI. However, when the function starts loading it shows an empty window and the gif only appears after the the QMessage box appears notifying that it is done.
How do I make it so that it will the gif will appear when it starts and closes once the function finishes loading. Thanks
