I have a time consuming code which runs in order to populate a combobox in my node dialog.
Currently I have kept this logic in NodeDialogPane::loadSettingsFrom(), but the issue is, when I click on ‘Configure’, it take more time before it opens the dialog. So the user doesn’t have any clue about this delay.
What I want is, just after the dialog is shown, I need to execute this time consuming code to populate the combobox.
Is there a way to do that?
