@Alain38-0 said in Problem with QTest, QGlWidget, and Qt5:

I have found a similar problem in my application

Please provide a Short, Self Contained, Correct (Compilable), Example (http://www.sscce.org/ ). Remove the confidential and unnecessary elements, and give us a compilable example (including a main() function, a simple class, and an output display) that demonstrates the problem. Otherwise, it's difficult to understand the problem.

Also, if you are on Qt 5.4 or newer, I suggest replacing QGLWidget with QOpenGLWidget. QOpenGLWidget resolves numerous issues with QGLWidget: https://blog.qt.io/blog/2014/09/10/qt-weekly-19-qopenglwidget/

Hi,

I may be wrong but based on this, it seems to be an unsupported use case for EGLFS.

Hi,

You connect statement is wrong. It should be:

connect(glwidget, SIGNAL(textChanged(QString)), ui->textEdit, SLOT(setText(QString)));

Never put the variable name in the SIGNAL or SLOT macros

Thank you for your reply.
Yes, that is probably the best to do. It will however require to switch to Qt5.4, and that is a larger endeavour. Will try that.

Thanks again!
