Completed to port my VST3 from VSTGUI 3.6 to 4.3. Now everything seem to work except, got a blank editor screen !
Almost all of the code is the same as the VSTGUI 3.6 version.
The Tuturial project however works ok (after some fixes as it did not use IControlListener etc…) In editor:open it calls CFrame* newFrame = new CFrame (frameSize, ptr, this); with three parameters instead of the required two. In my project that call fails to compile, but the tutorial it compiles ok (VS2015) even there is a small red warning in the VS editor. Wonder wonder. Perhaps that is a culprit somehow.
My open function is similar to the Tutorial project. Even newframe->setBackgroundColor(kGreenCColor) does not set the color. Bitmaps creation are ok and bitmap->isLoaded() all return success. When I move over the windows in VST3PluginHost I can see it shows those black boxes with the number for the controls so it look like the controls are there.
