You can have multiple top-level dialogs, all accepting input - I recall this question came up a little while ago - see attached message below. > I'm trying to have > a TabSet in the top class, where each TabItem contains a TabSet > with more TabItems inside it, but have not achieved success, > hence the question. You can certainly do this too - the TabItem can contain any Component, including a nested TabSet. I'm not sure how this relates to having multiple dialogs though, possibly I've misunderstood the gist of your question.... Hope this helps.

The problem with that approach is that show_modal blocks the other windows after both initially and init_dialog have been called, so any other windows will be blocked - not what you want. However, there is a way to do this by using the show_child() method, which is a sort of cross between show_modal and show_modeless. It doesn't block other windows (like show_modeless), but also it doesn't return until the window has closed (like show_modal). So, if the main method of my example program was as follows :- procedure main() d := dialog() d.show_modeless() d2 := dialog() d2.show_modeless() d3 := dialog() d3.show_child() end ..then you start off with all three dialogs on the screen and accepting input. The last line only returns when d3 is closed, and the program exits. This does mean that you can't close d3 and leave d and d2 open. To allow that, with all three dialogs on an "equal footing", custom code is needed :- procedure main() d1 := dialog() d1.show() d2 := dialog() d2.show() d3 := dialog() d3.show() dispatcher.add(d1) dispatcher.add(d2) dispatcher.add(d3) while *dispatcher.dialogs > 0 do dispatcher.message_loop(?dispatcher.dialogs) end "dispatcher" is the single instance of the class Dispatcher, which is the gui toolkit's event handling system.
