I’ve got an expanded GroupBox around another GroupBox that’s visibility is based on the type of file that is being displayed. I’d like the outer Group box (or the inner GroupBox) to display no border. When I try mainBox.setStyleName(HaloTheme.GROUPBOX_PANEL_BORDERLESS); in the java file or stylename=“borderless” in the xml file. I get a weird output as displayed in the link.
If I try mainBox.setBorderVisible(false); in the java code I get “UnsupportedOperationException”
