Samsung Posted March 20, 2020 Share Posted March 20, 2020 Hi! For the showing dynamic data i create runtime instance of TUniCanvas and it image change periodicaly via BitmapCanvas. Once created, it is transparent. But as soon as I draw something (even a simple line or change the color of one pixel) - transparency is lost Can I make it transparent permanently? Thanks!

erich.wanker Posted June 2, 2021 Share Posted June 2, 2021 Everything in picture 3 what is not in picture 2 should be in the uniCanvas .. The transparent uniCanvas should lay over the unidbgrid .. Quote Link to comment Share on other sites More sharing options...
