X** SCCS_data: @(#)WcName.c 1.1 ( 19 Nov 90 )
X**
X** Description: Implements several name-to-widget and widget-to-name
X** functions which are generally useful, especially a name
X** to widget function which really works:
X**
X** Widget WcFullNameToWidget(char* widget_name)
X**
X** The widget names understood by WcFullNameToWidget() are
X** a superset of those understood by XtNameToWidget in
X** the X11R4 version of libXt. XtNameToWidget only knows
X** how to find children of a reference widget, and so the
X** names start _below- the refernce widget. However,
X** WcFullNameToWidget knows how to find widgets anywhere
X** in the widget tree: it normally starts the name search
X** from the root of the widget tree, but it can also
X** perform the name search relatively from the reference
X** widget, both up and down the widget tree.
X**
X** When name searches start at the root of the widget
X** tree, the same syntax as that understood by Xrm is
X** used. Below are four examples of acceptable names:
X**
X** *foo *foo.XmRowColumn*glorp
X** Mri.some*other.foo *Form.glorp
X**
X** Note that components may be class names, such as
X** XmRowColumn, or may be instance names of the widgets.
X** Ambiguous names are resolved exactly as done by
X** XtNameToWidget: shallowest wins, `.' binds tighter
X** than `*', instance names bind tighter than class
X** names.
X**
X** In addition to resolving names from the root of the
X** widget tree, WcFullNameToWidget also can find widget
X** using a relative root prefix. Three special characters
X** are used:
X**
X** ^ means "parent"
X** ~ means the closest shell ancestor
X** . means start at the reference widget
X**
X** The relative root prefix characters are exactly that:
X** a prefix of a name which will then be passed to
X** XtNameToWidget. Some examples:
X**
X** .foo a child of the reference widget
X** ^foo a sibling of the reference widget
X** ^^foo a sibling of the ref' widgets's parent
X** ~foo a child of the shell ancestor.
X** ~~*foo some child of the shell's shell ancestor.
X**
X** The ^ and ~ prefix characters are only valid at the
X** beginning. They effectively operate on the reference
X** widget.
X**
X** In all cases, the characters are scanned left to right.
X** So, the first character is acted upon, then the second,
X** and so on.
X**
X** Notes: Most of the "private" part of this file goes away when
X** the bug in the Xt Intrinsics is fixed which causes
X** XtNameToWidget() to dump core whenever a Gadget exists
X** in the widget heirarchy...

X** Fixes: Added the two lines following this comment block.

X* Widget Creation Library
X*
X* Module_description:
X*
X* Since (for portability reasons) we can not assume runtime binding,
X* all widget classes, creation routines (constructors), and callbacks
X* must be "registered" by the application BEFORE widget tree creation.
X*
X* All four of the functions defined in this module load dynamically
X* allocated and extended arrays of structures. The size increment
X* of the arrays starts at a reasonably small size (INCR_REGISTRY,
X* initially 32), and is doubled in size everytime a given registry is
X* filled. This allows registries to be small, yet to not have to be
X* realloc'd frequently when they grow large.
X*
X* The registries are arrays of structs. In all four cases, the
X* structs are very similar: they contain a name string which holds the
X* class, constructor, or callback name as it was registered; a quark
X* which is based on an all lower case representation of the name, and
X* class, constructor, or callback specific information. The name
X* as registered should be as shown in reference documents and source
X* code, as it is used for user error messages.
X*
X* The registries are intended to be used by string-to-whatever converters.
X*
X* All four registration functions currently check for duplicate
X* entries, but do no fancy hashing scheme, nor any ties to the
X* application context. Assumming a relatively small number of
X* entries in these regestries, it is assumed that a sequential
X* search using quarks will be adequate and simple.

XDrawingArea Widget
X
X
XSYNOPSIS
X Application header file <X11/Xaw_d/DrawingA.h>
X Class header file <X11/Xaw_d/DrawingAP.h>
X Class drawingAreaWidgetClass
X Class Name DrawingArea
X Superclass Simple
X
X
XOVERVIEW
X This widget was needed to allow a drawing area in the Athena widget
X set that doesn't require hacking up the Label widget by adding
X complicated actions. This widget follows Motif's DrawingArea widget
X closely, except that it follows Athena's naming conventions and there
X is no resize policy. Also, Motif's Drawing area is a composite widget,
X while this one is a simple widget. This widget is NOT officially
X part of the Athena widget set.
X
X
XDESCRIPTION
X The DrawingArea widget is modeled after Motif's DrawingArea widget.
X The DrawingArea widget is an empty widget that is easily adaptable to
X a variety of purposes. It does no drawing and defines no behavior
X except for invoking callbacks. Callbacks notify the application when
X graphics need to be drawn (exposure events or widget resize) and when
X the widget receives input from the keyboard or mouse. Applications
X are responsible for defining appearence and behavior as needed in
X response to DrawingArea callbacks.
X
X
XClasses
X DrawingArea inherits behavior and resources from the Core and Simple
X classes.
X The class pointer is DrawingAreaWidgetClass. The class name is DrawingArea.
X
X
XNew Resources
X Name Class RepType Default Value
X ---- ----- ------- -------------
X exposeCallback Callback Pointer NULL
X inputCallback Callback Pointer NULL
X motionCallback Callback Pointer NULL
X resizeCallback Callback Pointer NULL
X
X XtNexposeCallback
X Specifies list of callbacks that is called when DrawingArea recieves
X an exposure event. The callback reason is XawCR_EXPOSE.
X XtNinputCallback
X Specifies list of callbacks that is called when DrawingArea recieves
X an keyboard or mouse event (key or button, up or down). The callback
X reason is XawCR_INPUT.
X XtNmotionCallback
X Specifies list of callbacks that is called when DrawingArea recieves
X a mouse motion event. The callback reason is XawCR_MOTION.
X XtNresizeCallback
X Specifies list of callbacks that is called when the DrawingArea is
X resized. The callback reason is XawCR_RESIZE.
X
X
XInherited Resources, Changed defaults
X Name Class RepType Default Value
X ---- ----- ------- -------------
X height Height Dimension 100
X width Width Dimension 100
X
X
XCallback Information
X A pointer to the following structure is returned with each callback.
X
X typedef struct {
X int reason;
X XEvent *event;
X Window window;
X } XawDrawingAreaCallbackStruct;
X
X reason: Indicates why the callback was invoked
X event: Points to the XEvent that triggered the callback
X window: Is set to the widget window
X
X
XBehavior
X <KeyDown>,<KeyUp>,<BtnDown>,<BtnUp>:
X The callbacks for XtNinputCallback are called when a key or button is
X pressed or released.
X <Expose>:
X The callbacks for XtNexposeCallbacks are called when the widget recieves
X an exposure event.
X <Configure>:
X The callbacks for XtNresizeCallbacks are called when the widget is resized.
X <Motion>:
X The callbacks for XtNmotionCallbacks are called when the widget recieves a
X pointer motion event.
X
X
XDefault Translations
X <BtnDown>: input()
X <BtnUp>: input()
X <KeyDown>: input()
X <KeyUp>: input()
X <Motion>: motion()
X <ResReq>: resize()
