QGLWidget : changing anti aliasing during run time

[Dong Back Kim]

Hi,

I have anti-aliasing in my QGLWidget, I set it the following way :

GLViewport(QWidget *parent) : QGLWidget(QGLFormat(QGL::SampleBuffers), parent) ...

GLViewport(QWidget *parent) : QGLWidget(QGLFormat(QGL::SampleBuffers), parent) ...

To copy to clipboard, switch view to plain text mode 

Later I try to change the format this way:

QGLFormat currentFormat = format();
	currentFormat.setSampleBuffers(true);
	currentFormat.setSamples(0);  
	setFormat(currentFormat);

QGLFormat currentFormat = format();
	currentFormat.setSampleBuffers(true);
	currentFormat.setSamples(0);  
	setFormat(currentFormat);

To copy to clipboard, switch view to plain text mode 

It has 2 effects :

1) it does not work
2) the mouse event are never called after this change !

Does someone have an idea ?

Hi,

When you said "it does not work", you mean multisampling is not working or something else?

The mouse event part is also bit weird. I don't think they are related each other, are they?
Try to use setMouseTracking(true) within the GLViewport.
