we are using g++ and Xlib to write applications on hp9000 workstations.
windows i have created have done what i wanted usually, but the window
manager (uwm) doesnt seem to know how to resize them... tho ive set all sorts ofhints and things. uwms  acts like its resizing - an outline of a smaller or
larger window appears, and a box with the dimensions of the oyutlined window. But
when the mouse button is released, the window is in its original state ..tho
it sometimes moves, apparently due to bit gravity.

similar windows programmmed in the x10 environment were resized ok.

below is the code for one such x11 application, a utility to display the
color map .
/*****************************************************************************

  File Name: showcolormap.cc
  Author: Jim Todd
  Creation Date:2/8/89
  Modified: 2/16/89
  Purpose: Show the current colors available on screen
           this version is designed for 16 color map, as 320s only support 16
  Compile With: g++ showcolormap.cc -lm -lX11
  Executable is in ~/bin/xcmap
  This version has transparent background

any suggestions ?
