My question is: is there a way to kill the ginput cursor if something outside the figure is clicked?

I wrote a code for a GUI. On that GUI there are several buttons and also a panel for displaying  figures. One of the displayed figure needs the user to click on the image in order to do some modification. 

My question is: while ginput is called and the cursor is shown on the screen, if the user clicks on a button outside the figure, is there a way to exit the ginput selection mode?
