This line

UBlabla blabla_widget = CreateWidget<UBlabla>((), UBlabla::StaticClass());

Creates the widget. But how can I put to constructor exposed on spawn variables?
Only manually?

blabla_widget->exp_a = 0;
blabla_widget->exp_b = 1;

~

blabla_widget->SetBlablaVariables(0, 1);

Or there are some more pretty ways to do it?

I’m having the same problem.

There no way to do it automatic, using spawn function. Good workaround is to create your own spawn function or maybe do a some C++ macro :slight_smile:

I’ve been doing this lately and my solution was to just create a function to run after setting my variables.
In my case I’m using a BlueprintImplementableEvent called InitializeWidget() which runs code I would generaly do in the OnConstruct event.

UBlabla blabla_widget = CreateWidget<UBlabla>((), UBlabla::StaticClass());

TestVar1 = 0;
TestVar2 = true;

InitializeWidget();
