EXTREME frustration with tooltips and _TrackMouseEvent( ), please help
Hello, I've been experimenting with tooltips, trying to figure them out. I almost have it, except the tooltip doesn't "behave" like a normal tooltip.
When in the client area, even if the mouse is stationary, it constantly updates the tooltip, so it never disappears. I think it's a problem with TRACKMOUSEEVENT in WM_MOUSEMOVE, but I don't know how to proceed from here.
Here's the code from the whole program, compilable. Hopefully someone in the future can benefit from this as well. I've searched and experimented for 4 days, and cannot quite get this right. :(
Any help would be greatly appreciated. Thanks! :)
EDIT: I forgot to mention, that the popup delay and the time before it updates the tooltip again are linked. If I set dwHoverTime to 3000, of course it takes 3 seconds to popup, but it also updates again after 3 seconds.
Before, when I was using createwindow and destroywindow when I'd update, it would constantly "blink" inside the client area cause it for some reason keeps updating continuously.
Also, I noticed, when using balloontip tooltips, it appears upside down. :(
