CHoverButton - A simple hoverbutton with one bitmap and a tooltip

Introduction

Looking around for some nice bitmap hover buttons, I just couldn't find what I was looking for. In this case there are a couple of things you can do:

1. Leave it.
2. Buy it.
3. Steal it.
4. Get it for free.
5. Start crying
6. Do it yourself (and possibly share it.)

I'll share!

I found another hoverbutton class that uses SetCapture() and ReleaseCapture(). Using this method gave me some problems. I can't remember why, but it did to me. So I thought why do it so difficult? MS has a nice API to handle hover states: _TrackMouseEvent().

So here it is... The class. After a long thought i decided to call it: CHoverButton. I used some classes and information found elsewhere (thanks to the people for that).

How to use it?

1. In you resource editor create a button and set the 'owner draw' property.
   
2. Use classwizard to create a CButton object in your dialog.
3. Include the "hoverbutton.h" file in your dialog class file.
4. Rename the CButton object type to CHoverButton.
5. Create a bitmap with three buttonstates: Up/Down/Hover. The pictures need to be right next to each other.
   The button will calculate it's own size = (the width of the bitmap)/3.
   You can use true color bitmaps here. See below for an example image.
   
6. In the OnInitDialog() load the bitmap with mybutton.LoadBitmap(IDC_MYBUTTON);
7. Set a tooltip with mybutton.SetToolTipText();
8. Compile and enjoy.

Have fun!
