Dynamically changing image bitmap for %ib button

Does anyone know if there's a way to dynamically change the bitmap used in a %ib button - not just the state but that actual bitmap. Failing that any method for hiding the button? Thanks, Alan

There is no way to change the bitmap without replacing the whole of the window. You can do this but it is quite tricky. That is, create a new window on top of the old one but with the modified attributes, then close the old window.

You can use the Plato 'Spy' tool to see if there is a hwnd (a Windows handle) associated with the button but this is very unlikely. A %tb would be the same but a row of %bt or %tt (or %bb) would have separate hwnds for each button so you could then hide each button at will. %bt and %bb can have images.

Paul, Actually I'm using multiple %ib which do give a window handle using %lc and I can move the buttons around, so I guess I could just have a pair of buttons and hide/move them in to place as required. Thanks.

i am interested in this too. Often needed
