Could of sworn i already created this topic...

Anyways, is there some userlib out there that will allow you to create tooltips for gadgets?

I was looking more towards a fully setup system to check if the cursor was over a gadget, or a defined area.. But I geuss i can just modify this...

I know that toolbar's have builtin tooltips, but haven't seen it elsewhere.

Here it is, did this under 2 hrs, fully functional :)

Very good, but sad that the main window blinks

Plash
 #7
Yeah, ill have to come up with a way to do it without using a window.

Andres

you can try drawing directly to DesktopBuffer() and before you draw there anything you'll copy the background of it and when you want to remove it then you'll just draw the background on the tooltip.

Yeah i figured that would be the best way to go, ill prolly come up with another version of it sometime later next week.
