First off the Aqua Skins look cool! Some time ago I
had started a library that allowed me to change the
look, feel and behaviour of an object. It uses a
setStyle(name,clear) function (based on a StyleManager
class). This StyleManager would allow me to set
properties and functions as follows:
var style={
backcolor : 'yellow',
preRender : function(o,style){
// some precreate code here
},
render : function(o,style,guiType){
if(guiType=='base') {
o.setBgColor(style.backcolor);
}
}
}
StyleManager.addStyle('buttoncolor');
lyr.setStyle('buttoncolor');
// I can also add multiple style object
lyr.setStyle('togglebutton');
