Okay I've continued at this for hours, I can't get it to find the button! My project is due tomorrow and I only have a few hours left to get it finished and I haven't even scratched the surface of the UI part. Any ways, here is the code:
Code:
<textures file="countries.png" format="RGBA">
<texture name="-countries.background.highlight" x="0" y="0" width="68" height="36"/>
</textures>
<textures file="countries.png" format="RGBA">
<select name="countries.background">
<alias ref="-countries.background.highlight" if="armed ^ selected"/>
<texture x="0" y="0" width="68" height="36"/>
</select>
</textures>
For the theme file.

I'm extremely new to TWL and by what I've read, the select tag (more specific the name part of it) is what the method searches for (countries.background) and for some reason it gives me this:
Code:
Could not find theme: countries.background
java.lang.IllegalArgumentException: child widget already in tree
at de.matthiasmann.twl.Widget.insertChild(Widget.java:1088)
at de.matthiasmann.twl.Widget.add(Widget.java:1066)
at com.adrian.spanish.MatchingStateOne.init(MatchingStateOne.java:65)
at org.newdawn.slick.state.StateBasedGame.init(StateBasedGame.java:164)
at org.newdawn.slick.AppGameContainer.setup(AppGameContainer.java:390)
at org.newdawn.slick.AppGameContainer.start(AppGameContainer.java:314)
at com.adrian.spanish.SpanishGameMain.main(SpanishGameMain.java:42)
Also, there is nothing wrong with the loading of the xml file because the TWL background loads fine referencing to a select tag.
