Thank you for your answer Alex. But what if the backgroundcolor is
unknown until the widget is instantiated?
The solution would be to have access to the widget instance properties
within the state function/method of the appearance.
How can this be solved? Sebastian? Any Idea?

Hi Dietrich,
i'm not sure this is this the correct way to do this, but you can try
smth. like this:
for( var i=0; i<listitems.length; i++)
{
listitems[i].addState("color"+[i]);
}
so all listitems have different States(color1, color2, color3...)
and then:
theme.registerAppearance("colored-list-item", {
setup : function() {
{
this.color1 = new qx.renderer.color.ColorObject("#FFFFF1");
this.color2 = new qx.renderer.color.ColorObject("FFFFF2");
.
.
},
and:
state : function(vTheme, vStates)
{
return {
backgroundColor : vStates.color1 ? this.color1 : (vStates.color2 ? :
this.color2..........
};
}
this is nothing i have tested - just an idea. I'm sure there should be a
better way to do this.
Cheers,

Hello List,
I'd like to create an appearance where I'm able to set the state
appearance depending on a widgets property. In the example above I've
defined a property backgroundColorUnselected which is set for each
instance individually.
So if the state changes to unselected the value of this property should
be passed back by the state part of the appearance. Before the last
changes to the appearance theme there was a parameter vWidget which
contained the instance of the widget the appearance was associated with.
How can this be done?
Here is an appearance skeleton which should help to understand my needs:
theme.registerAppearance("colored-list-item", {
setup : function() {
{
this.bgcolor_selected = new
qx.renderer.color.ColorObject("highlight");
this.color_selected = new
qx.renderer.color.ColorObject("highlighttext");
},
initial : function(vTheme)
{
/* initial code here */
},
state : function(vTheme, vStates)
{
return {
backgroundColor : vStates.selected ? this.bgcolor_selected :
widgetInstance.getBackgroundColorUnselected(),
color : vStates.selected ? this.color_selected : null
};
}
});
Thank you for your help.
Best regards...
