I need some help. I've scanned all the notes here, but to no avail. The problem is how to make a popup Modal dialog box appear centered in a certain widget no matter where that certain widget's window has been moved. It works fine for the first call. There after it always comes up in the same place. I've summed the ...->core.x and ...->core.y values for the "calling" widget and all it's ancestors. The final values of x and y do indeed vary as I move the "calling" widget around the screen. How do I make the popup box track it. It is a "popup_attached_db" widget with simpletext, label and a few push buttons. I've tried making a separate shell (ala 2106); I've tried XtSetNormalHints. 1) Can it be done? 2) What's the magic incantation? Any help appreciated. - norm

This may work:
Do an XtSetValues of XtNx and XtNy on the shell widget (the parent of
the dialog box itself) before you pop up the dialog box.
{Arg args[] = {{XtNx, x}, {XtNy, y}};
XtSetValues (XtParent (dialogBoxW), args, XtNumber (args));}

I was given the magic incantation. Much to my chagrin it was something
that I had tried earlier. Unfortunately I also had a couple of other
lines of code that were getting in the way and screwing things up.
A distilled version of the scenario goes like this...
void PopFunction(...)
{
static Widget PopW;
int x, y;
/* fetch it if it's the first time */
if (!PopW)
DwtFetchWidget(DRMid,topshell,&PopW,.......);
XtTranslateCoords(cW,cW->core.x,cW->core.y,&x,&y);
x += (cW->core.width/2) - (PopW->core.width/2);
y += (cW->core.height/2) - (PopW->core.height/2);
XtSetArg(args[0],DwtNx,x);
XtSetArg(args[1],DwtNy,y);
XtSetValues(PopW,args,2);
.
.
. more work...
.
.
XtManageChild(PopW);
}
cW is the widget id of the "calling" widget. Ie, the widget where PopW
is to be centered in.
