First steps UniGui - change button color

[Int3g3r]

Hello,

I'm new to UniGui and don't quite understand the ExtJS part of it.
I simply want to switch the color of a TUnimButton.

I found follow post that doesn't work for me.

But my biggest problem is how to interpret the documentation.

I found follow links to the ExtJS documentation.
- extjs/4.2.1
- extjs/6.2.0

1) How can i find out wich version of ExtJS UniGui uses ?

I know the basics of css, so i searched in the documentation for a method to change the style.
I found follow methods:
- 4.2.1 -> Ext.button.ButtonView.style()
- 6.2.0 -> Ext.button.ButtonView.setStyle()

Now i searched for "background". There are a lot of diffrent "theme tariables", i tried $button-default-base-color like follow.

ObjectInspector -> ClientEvents -> ExtEvents -> added

function added(sender, container, index, eOpts)
{
 MainmForm.UnimButton2.style($button-default-base-color:#FFFFFF);
 MainmForm.UnimButton2.style($button-default-base-color: 'red');
 MainmForm.UnimButton2.style(background:#FFFFFF);
 MainmForm.UnimButton2.style({background:#FFFFFF});
 MainmForm.UnimButton2.style({$button-default-base-color:#FFFFFF});
 //.. same with .setStyle()
}

 

In the post above he uses "CustomCSS" in the UniServerModule.
I tried this too but that doesn't work either.

2) I know it's case sensitive but I don't know what i'm doing wrong.
