HowI created some TV logo images, which I want to use as button, but the gallery only allows you to enter the bitmaps. Once the image is imported, it is in the bitmap tab and the properties for the image only display 3 tabs: label, appearance and dimantion.

How can I convert that image to a button? The guide only tells how to import images as bitmaps, but nothing about how to convert the images to the buttons.

Thanks
