QFrame parent, QGLWidget-based child

[philski]

hey folks,

I have a custom widget based off of a QGLWidget.

I set the widget's parent equal to a QFrame:

DrawWindow = new CTHV( myQFrame, 0, this);

and the widget shows up just fine on screen.

My problem is this: I can't get the QGLWidget to catch mouse clicks/keyboard events. The focus policy is set to QWidget::WheelFocus.

I've tried using setFocusProxy(DrawWindow) and it didn't work either.

Any ideas?

Thanks,

philski

The subject of the post is wrong, its about mouse grabbing not parent child problems.
Did you call setMouseTracking() for your widget?

@philski - Did you subclass QGLWidget in order to override the mouse press and key events? Also, The setting of the focus policy is not important here.

BTW, @high_flyer, setMouseTracking() is only required if you want to capture mouse move events.

You are right, I stand corrected.

Chicken Blood:

My QGLWidget has a mousePressEvent() handler that simply writes to console when activated:


void CTHV::mousePressEvent(QMouseEvent e)
{
printf("Mouse Press Event!\n");
}

but it never appears.

'e' needs to be a pointer:

void CTHV::mousePressEvent(QMouseEvent *e)
{
printf("Mouse Press Event!\n");
}

void CTHV::mousePressEvent(QMouseEvent *e)
{
printf("Mouse Press Event!\n");
}
