I have a plugin which performs a download in the background and I would like to send progress updates to the UI. And I have been struggling for days to find a way to trigger / broadcast / send an event from C++ to a user widget that I put together in the editor (it’s all BP). Also, because this is for a plugin, I don’t want to have specific widget code in my plugin. Ideally, I just want…
plugin.cpp
void OnDownloadFinished() { sendDownloadFinished(); }
And then in some arbitrary UI’s Graph Editor right click and search for node “On Download Finished”.
What is the proper UE4 way of doing this?
Things I have tried:
DECLARE_EVENT: doesn’t show up in the graph editor
Interfaces: seem to require a pointer to the widget from my plugin code to trigger, which I don’t know how to get, especially since the end user of my plugin might not even have a widget that listens to my event. And my BlueprintImplementableEvents still don’t show up in the graph editor anyway.
Very frustrating
