Are you using the plain GLwDrawingArea or the Motif one, GLwMDrawingArea?

Is it the one provided by XFree86, by SGI/Irix or the original code from
Doug Young's book?

It's a GLwMDrawingArea widget. I am running on a Sun box, Solaris 7.5
(moving up to 8.0 shortly from what I'm hearing from our Tools team).

I'll even do you one better - here's the code creating the widget:

////////////////////////////////////////////////////////////
// Method: initialize
//
// Purpose: do the initialization needed for
// GlobeScreen once all the values are
// set by Session being managed.
//
void
DcGui_Impl::GlobeScreen::initialize()
{

// take out the openGL lock to safeguard the openGL commands

GlobeOpenGLLock lock;


// now create the widget. This has to be the OpenGL version of the
// Motif Drawing Area widget to ensure that the visual and depth
are set
// properly.
//
Arg al[64];
int num = 0;
XtSetArg(al[num], XmNtopAttachment, XmATTACH_FORM); num++;
XtSetArg(al[num], XmNbottomAttachment, XmATTACH_FORM); num++;
XtSetArg(al[num], XmNleftAttachment, XmATTACH_FORM); num++;
XtSetArg(al[num], XmNrightAttachment, XmATTACH_FORM); num++;
XtSetArg(al[num], GLwNvisualInfo, vi_); num++;
XtSetArg(al[num], XtNcolormap, colormap_); num++;
XtSetArg(al[num], XmNkeyboardFocusPolicy, XmEXPLICIT); num++;
XtSetArg(al[num], XmNtraversalOn, TRUE); num++;
XtSetArg(al[num], XmNhighlightThickness, 2); num++;

// create the drawing area with the all the settings and the
// name that was set
drawingArea_ =
GLwCreateMDrawingArea(parent_,
const_cast<char *>(widgetName_.c_str()),
al, num);

// create callbacks on the drawing area

// gets called when the OpenGL drawing Area gets first created
XtAddCallback(drawingArea_, GLwNginitCallback,
initCB, (XtPointer) this);

// gets called when another window moves off of the widget
// The GLwNexposeCallback automatically compresses multiple
// Expose events into a single callback.
//
XtAddCallback(drawingArea_, GLwNexposeCallback,
exposeCB, (XtPointer)this);

// gets called with input. This will be mouse only. The
// keyboard commands get caught by session window.
XtAddCallback(drawingArea_, GLwNinputCallback,
inputCB, (XtPointer)this);

// Manage this new widget
XtManageChild(drawingArea_);

} // end of GlobeScreen initialize

Am I missing something here??

Thanks
Ryan

Are you sure you aren't updating another field on your GUI that causes
focus to shift there?

Yeah - preaty sure, I still have focus after a redraw, as the widget
still is accepting keyboard input. The only issue is that the focus
border is going away.

Ryan

Hmm, I'm pretty sure this is a Motif issue, not an OPENGL one.

If you TAB around, do you see where focus is? I never explicitly set the
Motif traversal
policy, & life is just fine. Indeed, with pointer focus, you don't need to
have a highlight
border...

Bump - anyone have any ideas?? The only thing I can think of is to
create a new widget, and set the focus to that dummy widget, just so I
can have my drawing area take it back after every redraw - but this I
do believe will result in a flicker of the focus border - which is not
desireable.

Thanks
