Non-rounded corners on widget controller output panels?

RandyMcGregor_BMcD — Mon, 23 Feb 2026 15:35:52 GMT

Is it possible to square off the rounded corners on the output panels of a widget controller? Defaulting to rounded edges is a recent development and we have some templates where that doesn't work.

Thank you,

Randy McGregor.

Hello @RandyMcGregor_BMcD

Yes, you can configure this in the Style tab for the widget using the Border radius.

When set to 0, the corners are squared.

All the widget panels (including controller floating panels) have rounded corners by default. You can use the Border radius option in the theme settings to select different corner styles. However, please note that it will affect all the panel corner styles in your ExB app. The Widget Controller itself doesn't have such configurations at the moment.

Thank you Shen. That did it. I had checked that, but was getting a limited set of options that did not include corner-handling. I just started over with one of the templates, and that did have that setting.

Thanks but I think I need a different method. The widgets are in a widget controller and I need to adjust the widget controller. Looks like this is possible, but I've got to sort out why I'm not seeing the settings I need
