/*
 * Focus Policy
 */


Q. When the window/workspace manager keyboardFocusPolicy == pointer,
   how can I help the user dismiss one of my application's modal
   dialogs without forcing the user to move the mouse?  Should I 
   warp the pointer?

A. If the user has chosen pointer focus policy, the user has declared that 
   she wants to control the focus directly.  We believe an application
   should not warp the pointer.  [ In any case, when the user grows up,
   he will change to explicit keyboardFocusPolicy  :-) ]

/*
 * Backdrops
 */

Q. I set a gif image into my root window, but I can't see it with DT.
   How come?

A. DT normally covers the root windows with backdrops for each
   workspace. Your image is there, but the root window is covered, so 
   you can't see it. To disable backdrops, add a resource like:

       Dtwm*<screen_name>*<workspace_name>*backdrop*image: none

   example:

       Dtwm*HighResHighColor*One*backdrop*image: none

   This disables backdrops for workspace One and lets the root window
   show through.


/*
 * Killing Windows
 */

Q. How do I stop the window manager from killing my client when the 
   user double-clicks on the system menu box?

A. There are two ways of approaching this. 

   1. Set the clientFunctions for your client to disable the "Close"
      item. This will work with mwm or dtwm. For example:

	  Dtwm*Console*clientFunctions:     -close
	
      disables "close" for the Console window.


   2. Modify your client to follow the WM_DELETE_WINDOW protocol as
      described in the ICCCM. This will work with any window manager.
      If your client is Motif you can:

      a. Call XmAddWMProtocolCallback to add a WM_DELETE_WINDOW
	 callback.

      b. Set XmNdeleteResponse to XmDO_NOTHING so that VendorShell
	 won't destroy the window when the WM_DELETE_WINDOW comes
	 in.

      This allows your client to post a "Are You Sure?" dialog when
      "Close" is activated. Your client decides when and if it should
      die in this case.

/*
 * Making a window larger than the screen
 */


Q. How can I map a window to be larger than the screen. For example
   I have a 14 inch monitor and I want my term windows to use a large font.
   The window manager does not let my term window map to a larger than
   screen size so I get less than 80 columns.

A. There are a number of resources that affect this behavior

   1) Set the "limitResize" resource to false.

   2) The other thing is to specify an explicit maximum size for your
      term windows. Mwm/dtwm computes the maximum size to fit on the screen
      by default. You could do something like:

    Dtwm*xterm*maximumClientSize:  160x66

      so that 80x24 windows will come up regardless of whether they
      fit on the screen or not. 

   3) There may be other resource lurking out there (such as in 
      /usr/lib/X11/app-defaults/Dtwm, xrdb, $HOME/Dtwm, etc.) that are more 
      specific than the "*resource" specs you have given. If so, they'll 
      win. Try being more specific. If that fixes it, then you'll probably 
      want to find out where your resources are coming from (app-defaults, 
      xrdb, $HOME/Dtwm, etc.).
