I'm creating a floating toolbar that sits on the desktop, it's a row of vertical icons and when one is clicked, another toolbar pops horizontally from the side of it (like in Photoshop / Paintshop Pro), but I want this toolbar to be hidden at the side of the screen until my mouse moves to the edge, then the toolbar slides into view.
Double click on the button or object , then go up to the top where it says "on click" and choose mouse hover. Then enter the code to show it. Then I think there is the same deal with on mouse leave or something so you can hide it again.
