295 png import images

[Jan Schenkel]

Hi Phil,

The trick is to use an image, set the icon of the button to the id of said image, and then change the filename of the image; your button will automagically be repainted when you change the filename of the image control.

As a quick test, I created a stack with a button and an image; I named the image control "MyButtonIcon"; and then I set the script of the button to:
##
on mouseUp
   answer file "Select an image for my icon"
   if it is empty then exit mouseUp
   set the fileName of image "MyButtonIcon" to it
   if the icon of me is 0 then set the icon of me to "MyButtonIcon"
end mouseUp
##

When I click the button, I can go find an image file and the button gets it as a shiny new icon :-)


HTH,

Jan.

It didn't work here - 'filename' isn't a button property, and setting the icon 
to a url doesn't work either. However, you can make an image object act pretty 
much like a button, responding to mouse clicks and such.
