    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!
