{ TOButton component version 1.0, copyright © A. Meeder, 1996

** It"s freeware, so you don"t have to pay me, but I do not guarantee the working of it

The idea came from the personal assistent of MS Office 97. To use this component:
Drop the component on your form and position it where you want to have it.

This are the special properties:
* BorderColor, color of the border when the button has the mouse
* BorderWidth, basic width of the border (1 .. 3)
* DownGlyph, LED-bitmap when the button is down, you can use your own bitmap
* OffGlyph, LED-bitmap when the mouse is not over the button, you can use your own bitmap
* OnGlyph, LED-bitmap when the mouse is over the button, you can use your own bitmap
* RoundSize, used to change the corners of the button
* TransParentcolor, color of the LED-bitmaps to make transparent

If you have suggestions about TOButton or make changes, please mail me: ameeder@dds.nl
