* TITLE guiSubr.c - general gui routines for xview
*
* DESCRIPTION
* These routines comprise an initial attempt to provide gui capabilities
* in a generic way. At present, the routines are heavily xview
* oriented. The routines will probably evolve, especially with
* regard to xview item typedef usage (e.g., Panel, Xv_opaque, etc.).
*
* For more information, see USAGE, below.
*
* QUICK REFERENCE

* key1, val1, key2, val2)
* Panel_item guiMessage(label, panel, <>pX, pY, <>pHt)
* void guiMessagePrintf(Panel_item, fmt, ...)

* void guiNoticeFile(pGuiCtx, msg, fName)

* int guiTextswPuts(textsw, pBuf, <>pCharPos)
* void guiTextswReset(textsw)
* void guiTimer(seconds, callbackFn, callbackArg)
*
* NOTES
* 1. Many guiXxx routines have <>pX,pY,<>pHt as arguments. pX,pY specifies
* the desired position, in pixels, of the item within the panel. pX
* is modified to be a suitable x position for an item following on
* the same line. pHt is modified to be the height, in pixels, of the
* item, if its height exceeds the present value of pHt.
*
* BUGS
* o although they provide some isolation, these routines are still heavily
* XView specific
* o there is no "signal handler" routine to allow trapping a window
* manager forced exit
*
* USAGE
* In the synopsis for each routine, the `pGuiCtx' is intended to be
* &guiContext, (or whatever name is chosen for the GUI_CTX in the
* program).
*
* EXAMPLE PROGRAM
* This example shows some of the features of these routines. It
* produces a program which can be used as a computerized logbook.
* In addition to an editor and a "directory lister", the program
* has a button which starts a new logbook entry with time, date,
* and user name.
*
* This example assumes that the icon editor has been used to make
* an icon for the program.

* NAME guiCheckbox - create an empty checkbox list
*
* DESCRIPTION
* Creates the framework for an empty checkbox selection list. The
* actual checkbox items must be filled in by calls to
* guiCheckboxItem.
*
* Checkbox lists have a fixed number of items--the number of items
* can't be increased or decreased after the empty list is created.
* Individual items on a list can be changed at any time, however.
*
* RETURNS
* Panel_item for the checkbox
*
* BUGS
* o list can't dynamically grow and shrink
* o the maximum size for a checkbox list is 10 items
*
* SEE ALSO
* guiCheckboxItem
*
* EXAMPLE
* Set up a 3-item checkbox. Each of the first two items is to have
* an associated status message. The appearance of the setup will
* resemble the following:
*
* Retrieve from:
* [] text file ________status message________
* [] binary file ________status message________
* [] Channel Access
*
* The third item will be the default. When any of the items are
* selected, choose_xvo() is to be called; that routine uses a pointer
* to a `myStruct' structure for its operations.
*
* struct myStruct {
* Panel_item textStatus; status for text file
* Panel_item binStatus; status for binary file
* } context;
*#define PCTX 101 (a unique integer for identifying myStruct)
* Panel_item ckbx;
* int x=5, y=5, ht=0;
* int x1, x2, y1, y2; (for aligning buttons and status messages)
*
* ckbx = guiCheckbox("Retrieve from:", panel, 3, &x, &y, &ht,
* choose_xvo, PCTX, &context, 0, NULL);
* y += ht + 5; x = 5; ht = 0;
* guiCheckboxItem("text file", ckbx, 0, 0, &x, &y, &ht);
* x1 = x; y1 =y;
* y += ht + 5; x = 5; ht = 0;
* guiCheckboxItem("binary file", ckbx, 1, 0, &x, &y, &ht);
* x2 = x; y2 =y;
* y += ht + 5; x = 5; ht = 0;
* guiCheckboxItem("Channel Access", ckbx, 2, 1, &x, &y, &ht);
* y += ht + 5; x = 5; ht = 0;
* if (x1 < x2) x1 = x2; (which extends further right?)
* else x2 = x1;
* context.textStatus = guiMessage("", panel, &x1, &y1, &ht);
* context.binStatus = guiMessage("", panel, &x2, &y2, &ht);

* NAME guiEditor - create a text editor command frame
*
* DESCRIPTION
* Creates a text editor command frame with amenities to support good
* editing practice:
* o allow specifying directory and file
* o support easy access to a list of directory contents
* o easy choice of file name from directory list
* o "locking" of file under edit, with corresponding notification
* to users who try to edit a locked file
* o support for caller to add items to the text editor panel
* o check for write permission before allowing editing
*
* If the caller specifies a file name, then that file will be loaded
* automatically into the text subwindow. (If the file doesn't
* exist, a notice will pop up.)
*
* If the caller specifies a function to be called to add items to
* the editor panel, the function will be called as follows:
*
* void addExtrasFn(pGuiCtx, pEdit, panel, pX,pY,pHt, addExtrasArg)
*
* RETURNS
* GUI_EDIT *, or
* NULL
*
* BUGS
* o doesn't allow printing "memory" copy of file, and insists that user
* save the file if it has been modified
* o doesn't provide a way to save updates if the program aborts
