From 0e1683ef848d1d877e26633609fa95e0d2ab36b5 Mon Sep 17 00:00:00 2001 From: Joogab Yun Date: Wed, 16 Sep 2020 15:22:08 +0900 Subject: [PATCH 1/1] Add null check for mTextureSet. For empty text, text-visual doesn't create a textureSet. So it happens that mTextureSet is null. (sample) void Create(Application& application) { // Get a handle to the window Window window = application.GetWindow(); window.SetBackgroundColor(Color::WHITE); textLabel = TextLabel::New(); textLabel.SetProperty( Actor::Property::SIZE, Vector2(300.f, 200.f)); textLabel.SetProperty( Toolkit::TextLabel::Property::TEXT, "" ); textLabel.SetProperty( Toolkit::TextLabel::Property::ENABLE_AUTO_SCROLL, true ); window.Add(textLabel); // Respond to a touch anywhere on the window window.GetRootLayer().TouchedSignal().Connect(this, &HelloWorldController::OnTouch); } bool OnTouch(Actor actor, const TouchEvent& touch) { textLabel.SetProperty( Toolkit::TextLabel::Property::TEXT, "" ); textLabel.SetProperty( Toolkit::TextLabel::Property::ENABLE_AUTO_SCROLL, false ); return true; } Change-Id: Iff50abb0278c7d2f650a8c92cf8d5c5eaec6f36a --- dali-toolkit/internal/text/text-scroller.cpp | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) mode change 100644 => 100755 dali-toolkit/internal/text/text-scroller.cpp diff --git a/dali-toolkit/internal/text/text-scroller.cpp b/dali-toolkit/internal/text/text-scroller.cpp old mode 100644 new mode 100755 index 22f1156..6d0930b --- a/dali-toolkit/internal/text/text-scroller.cpp +++ b/dali-toolkit/internal/text/text-scroller.cpp @@ -271,7 +271,10 @@ void TextScroller::SetParameters( Actor scrollingTextActor, Renderer renderer, T // Reset to the original shader and texture before scrolling mRenderer.SetShader(mShader); - mRenderer.SetTextures( mTextureSet ); + if( mTextureSet ) + { + mRenderer.SetTextures( mTextureSet ); + } } mShader = mRenderer.GetShader(); -- 2.7.4
