Change font-size on GXT button.

[SmokerQC]

Hello, I'm trying to change the font-size of the text on a GXT button but that doesn't work. I tried this way.

My CSS

.myCSS .x-btn-text {
       font-size: 20px;
}

Then, in my code I do myBtn.setStyleName("myCSS");


Here is the result! font-size is ok but a "normal" button is on top of the GXT button.

setStyleName is clearing out other styles. What you want to do is addStyleName

Thank you, it works like a charm!
