Image as button

[xinyiman]

I want to use an image as if it were a button. What should I do because I do click on the corners when I press a button? And how do you release the button?

[xinyiman]

Let me explain, I wish that when I go with the mouse on the image edge and turns gray when you click on the board must look to the edge of the button clicked, and when the issue should go on as before. Ideas? Suggestions?

I still don't quite understand actually. Just use TImage and its OnClick property. What else do you need?

[xinyiman]

An example. I do not know how to handle the edge TImage object like a button!

You could draw two images on an image editor and use them to simulate button up and down.

Use OnMouseDown and OnMouseUp event handlers.

Thank you

well if you're there, it's a shame not to use three images (one for hover). here's an example - add to TImage components to the form, load a 75x75 image into the first (component size can be anything, even 0x0) and set the size of second TImage to 75x25. then add the following:
Image2MouseDown
  Image2.Canvas.CopyRect(Rect(0, 0, 75, 25), Image1.Canvas, Rect(0, 50, 75, 75))

Image2MouseEnter
  Image2.Canvas.CopyRect(Rect(0, 0, 75, 25), Image1.Canvas, Rect(0, 25, 75, 50))

Image2MouseLeave  (call this one from FormCreate)
  Image2.Canvas.CopyRect(Rect(0, 0, 75, 25), Image1.Canvas, Rect(0, 0, 75, 25))

Image2MouseUp
  if PtInRect(Image2.BoundsRect, ScreenToClient(Mouse.CursorPos)) then
    Image2MouseEnter(nil)
  else
    Image2MouseLeave(nil)

oh, and use constants for those rectangles.
