C++ (Cpp) ViewParams Examples

Example #1

File: WidgetBlueprintEditor.cpp Project: colwalder/unrealengine

TSharedPtr<ISequencer>& FWidgetBlueprintEditor::GetSequencer()
{
	if(!Sequencer.IsValid())
	{
		FSequencerViewParams ViewParams( TEXT( "UMGSequencerSettings" ) );

		ViewParams.InitialScrubPosition = 0;
		ViewParams.OnGetAddMenuContent = FOnGetAddMenuContent::CreateSP(this, &FWidgetBlueprintEditor::OnGetAnimationAddMenuContent);
