Hi all,

I have done the following steps to create an rcp application

1. Created a rcp application (3.x)

2. created extension point "org.eclipse.e4.ui.css.swt.theme" and added two themes in it and set

the respective css files for each theme.

3. Added a ViewerPreferencePage, which given the option to change theme.

Now, when i change theme , it work's fine and applied on all the swt controls which i have

specified in css file,

Now i have defined my own selector in the css file like "MySelector" and then specified it's

properties
like this

.MySelector
{
background-color:rgb(250,250,200);
}

i have debugged the code, the main class handling this is the "ThemeEngine", which reads this, one

thing for sure is that engine successfully read the whole css file including my own custom

selector, now what i want's is to get this selector and it's properties and values from the css

engine programmatically


Any idea/help/hint/clue/suggestion will be appreciated.

Regards,
SDK

Hi,
I am not sure, why you need this. The API only offers to retrieve the
Style for a widget. A hack possible would be to create a widget and
assign the selector as css class to it.
Cheers
