I have two questions concerning widgets.  I am running X V11 R3 on a Sun 3/60
with the HP widget set (from expo.lcs.mit.edu).  I am a relative newcomer to
writing user-interface code using X, having done lots of it in SunView.

My questions are these:

1.  Is there a way that I can 'turn a widget off'; set some flag so that it
    does not get drawn?  In SunView, one can set the PANEL_SHOW_ITEM field
    of a button, etc. to FALSE and that will do what I want.  I have not 
    found anything similar (yet) in X.

2.  I have a popup window, a dialog box really, which I do not want the user
    to be able to move while it is popped up.  Any ideas out there as to how
    that might be accomplished?  I tried adding an event handler for 
    MotionNotify events to the popup widget (a transientShellWidget) to no
    success.  I know it can be done, the popups in FrameMaker under X do this.

Any help is greatly appreciated.
