How to really refesh a dialog built by nasal

[mhab]

Hello

I am working to improve the "AI/Traffic and Scenario Settings" dialog (scenario.xml) in a way so different types of scenarios can be filtered via a combo element.
The dialog displays checkboxes, one for each scenario. All these checkboxes are generated by nasal code from within the <nasal><open> ... </open></nasal> tag.
So after I figured out how to filter the scenarios I end up with one remaining problem.

If I change the filter so that more entries (checkboxes) appear I get the dialog refreshed by closing/opening it.

Problem: If the filter results in less than the currently displayed checkboxes, the closing/opening doesn't work well, as the unwanted checkboxes still remain.
If I reload the GUI then everything is refreshed as wanted.

Question: Is there a way to "really/completely" refresh the whole dialog in the way "reload GUI" does it ?

Thanks

Hello

I found a way to refresh the dialog completely.
What I do in the bindings of the related widgets is the following:

Code: Select all

      <binding>
        <command>nasal</command>
        <script>
         ...
          var args = {'subsystem':'gui'};
          fgcommand("reinit",args);
        </script>
      </binding>


This is what's behind "reload GUI".

$FG_ROOT/Docs/README.commands and README.gui, see menubar.xml for other examples.
Note that "list dialogs" (multiplayer, pilot-list and performance monitor) often still end up closing/re-creating the dialog
