I am trying to spawn a widget from a class that derives from object, when I compile I get the message: “Pin World Context object must have a connection” however the create widget node has no such pin and I am unable to expand it like with other nodes.
Is there any way around this? If needs be I can rework part of my code but I’d like to avoid that if possible.
Cheers!
Screen shot?
Hmm, never tried making a widget like that. Seems you can’t create a widget from the object base class. Looks like you need to reparent this BP to an actor class.
World Context Object is a hidden pin. It’s required for nodes, which do need a world to work, and evidently, Create Widget is one of these, meaning you can’t use it from any class, that provides no world (and UObject does not).
Create C++ parent for your UObject and override GetWorld() fund in it.
Implementation would be like:
UWorld* UUiManager::GetWorld() const
{
if (GetOuter())
{
return GetOuter()->GetWorld();
}
return nullptr;
}My workaround was constructing it as Object instead Widget, it will ask you for an outer, but you can create a function/event that receives any actor as parameter.
As you can see, someone calls the UObject and asks it to create a button.
And that’s it.
If you CAN’T pull the CanvasPanel reference pin from your widget it is because is not public. Remember to tick the checkbox in: Is Variable
