I was able to test your code and I modified it to include ImageGadget within the Container gadget. I resized the Container gadget to the same size as the ImageGadget to give the illusion that its just an image. Then coded the image switcheroo when capturing the Container events.
Here is the revised code now with hover goodness:
Code: Select all
; From glib-2.0/gobject/gsignal.h:239
; #define g_signal_connect(instance, detailed_signal, c_handler, Data) \
; g_signal_connect_data ((instance), (detailed_signal), (c_handler), (Data), NULL, (GConnectFlags) 0)
UsePNGImageDecoder()

#MyImageGadget = 12
#MyImage = 21
#MyImage1 = 22
#MyImage2 = 23

BTW, I noticed that the container gadget needs to be 4 pixels wider and 4 pixels higher than the image gadget, not a big deal.
Thanks again.
