Show a UI popup or anything alike with a message

Depends on where your code is running:
  • if you are adding code to a customized version of OBS, or writing a plugin, then sure: use QMessageBox or do anything else you like
  • if you are writing a script in Lua or Python for OBS, then I believe your UI is limited to what is allowed on the "Tools", "Scripts" dialog
  • if your code is running in a browser source or browser dock, then you can show whatever you want within the context of the source or dock. For example, I wrote a browser dock to let me select or edit presets for a PTZ camera. A "save/load" button reconfigures the UI to show what looks like a modal dialog with controls for saving or loading presets to a file. The dock interacts with the camera via VISCA, and with OBS using Websocket.

The trick here is to use undocumented
Code: 
obs_queue_task(OBS_TASK_UI, yourFunctionShowingPopup, ...)
to ensure the function runs with next UI thread - credits to Warmuptill who already utilized it in Advanced Scene Switcher.

when you say Warmuptill already implemented in Advanced Scene Switcher can you elaborate? I am using AdvSS just for its websocket trigger and sending a custom message from outside to it and then having AdvSS get the message and dump the message in a text source and fire a hotkey that calls my Lua script so I can act on it. What I'd like to do now is throw up a dialog box if any error occurs in those scripts. I'm assuming the code above can only be used in C++ or can I use it from Lua to popup a dialog. If only in C++, did Warmuptill put something in AdvSS that I could use as an action to popup a dialog? I did not see any kind of dialog popop action. Any other idea would be appreciated as well (I thought about writing a file with the error as an html file then opening that in interact mode but that seems really hacky).

That is unrelated to the topic of development - for questions like this I recommend asking in AdvSS topic next time.

Anyways, I started working on widget action for AdvSS a while back (more or less when this question was asked), never got to finish it. https://github.com/WarmUpTill/SceneSwitcher/pull/899 And won't finish it anytime soon likely, as my IDE of choice started lagging hard with new version and C++ recently. So you'll have to wait or motivate me somehow :P
