What is the best way to popup a window in IDEA from plugin

Hello mark,

If I want to open a Dialog with some components inside for the user to
select, is there a recommended example/way or do I just use standard
Swing dialogs/JFrame classes?

You should use the DialogWrapper base class for your dialog. You can find
many examples of its usage in different third-party plugins.

Thanks. Thats very helpful.

if you need a less weighted popup you may consider using
ComponentPopupBuilder popupBuilder = JBPopupFactory.getInstance().createComponentPopupBuilder();
JBPopup popup = popupBuilder.createPopup();

You can specify the main component to be rendered in the center of the popup and as well the component to be focused.
