Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

UMG Widget - Cannot Interact


I've created a Multiline Text Editable Box and added it to an Actor as a component. I walk directly up to the component and try to interact with it. I can almost highlight text using the mouse, and it will highlight, but the flashing text cursor does not show up. I cannot type either, and if I right click on the text box, the entire editor crashes with a stake trace:

 Unknown exception - code 00000001 (first/second chance not available)

Any ideas? I wanted to make an interactive ingame notebook. So this is fairly essential. Any help is appreciated!

Hey aaron,

since your error says Unknown exception, i cant help you with that. This is epics responsibility

But assuming you created a 3D Widget in your notebook actor i would give you the hint, that the 3D Widget are still experimental and knowing that i wouldnt do any more magic than just showing off a widget in your gameworld. Until this feature isnt in a stable stage i prevent myself from being frustrated, because you cannot be sure if YOU do something wrong or your desired function is just not possible yet ;)

However its good to tell them the bugreport. Maybe im totally wrong here and you will get an Epic Answer by Epic Games from an Epic Games Staff Member ;)

best regards

I figured as much myself, really wanted to see if anyone had run into this bug before. I should also note this exists in both 4.7 preview versions of the engine. Looks like I'll need to integrate another solution for a GUI. I may look into integrating libRocket or maybe CEF.

Hey aaron, same problem here. By spawning a 3D Widget I can't edit any textboxes on the widget; if I type a few seconds it crashes UE4 with a similar error report. Just as Wallhalla said this is all experimental so it might be a bug, hope they'll address this soon since my game is heavily dependent on that =)

Widgets have been experimental for over 3 years. This is one of many half-assed projects from Nick Darnell. Functionality has changed non-stop. They clearly didn't map this logic out.
