Hi all,
I was wondering if anyone has an example demonstrating how to use image
sprites for different button states?
I understand that sprites work by setting the background position of a
background image, but I'm having trouble figuring out what widget to use for
this effect, and where I specify the image source. So far, the approach I've
tried is the following: I have a qx.ui.form.Button widget, which has an
appearance "header-button", and I tried creating another appearance selector
"header-button/icon" that specifies different decorators for different
states. Each decorator has a different backgroundPosition value. I want to
be able to specify the image source in the main JS code that sets up my
form---it would be a pain to create a different appearance and set of
decorators for each individual button/image. My current thought was to try
to create the button without an image source specified and then dynamically
set the decorator's background image. But this didn't work. I did not try
simply setting the button's image sources as usual, since I don't see how
changing the backgroundPosition in the decorator would make its way to the
position of the image inside in the button.
Any tips on how to hook all this up would be much appreciated. Thanks!
