Unsolved QOpenGLWidget doesn't draw OpenGL frame on macOS Mojave until a resize event occurs while built with CMake
-
Greetings:
I noticed that my QOpenGLWidget-based application (Qt ver. 5.12.0) doesn't display the OpenGL portion of the window until the window is resized on macOS Mojave (ver. 10.14.2) if I build with CMake as opposed to
qmake
. I observed this issue with Qt's "hellogl2" example as well. Does anyone have any thoughts? I have the "hellogl2" project file below along with what I thought its appropriate CMake counterpart would be (heavily influenced from Qt's CMake Manual). Thank you for your help with this.File
hellogl2.pro
HEADERS = glwidget.h \ window.h \ mainwindow.h \ logo.h SOURCES = glwidget.cpp \ main.cpp \ window.cpp \ mainwindow.cpp \ logo.cpp QT += widgets # install target.path = $$[QT_INSTALL_EXAMPLES]/opengl/hellogl2 INSTALLS += target
