how to restrict opening multiple Windows of the same Addon

[Kdevineni]

Hi

I am working on the AddOn which opens new NTTab (NTWindow) from the menu click.

Multiple windows of the same AddOn can be opened from the menu...

How do I restrict it to singe window, don't want to let the user open if its already open.

Please advice

Hello Kdevineni,

Thank you for your post.

You could loop through all active windows and detect if another window is open.

Here is a forum post with example code:
