How to set focus on a SEditableTextBox

Development Programming & Scripting C++

I tried：

	FSlateApplication::Get().SetKeyboardFocus(InputWidget,EFocusCause::SetDirectly);

However it did not work QAQ

Finally I reference the code of SAssetPicker.cpp

if ( InArgs._AssetPickerConfig.bFocusSearchBoxWhenOpened )
	{
		RegisterActiveTimer( 0.f, FWidgetActiveTimerDelegate::CreateSP( this, &SAssetPicker::SetFocusPostConstruct ) );
	}

And In SetFocusPostConstruct :

EActiveTimerReturnType SAssetPicker::SetFocusPostConstruct( double InCurrentTime, float InDeltaTime )
{
	if ( SearchBoxPtr.IsValid() )
	{
		FWidgetPath WidgetToFocusPath;
		FSlateApplication::Get().GeneratePathToWidgetUnchecked( SearchBoxPtr.ToSharedRef(), WidgetToFocusPath );
		FSlateApplication::Get().SetKeyboardFocus( WidgetToFocusPath, EFocusCause::SetDirectly );
		WidgetToFocusPath.GetWindow()->SetWidgetToFocusOnActivate(SearchBoxPtr);

		return EActiveTimerReturnType::Stop;
	}

	return EActiveTimerReturnType::Continue;
}

It works.
