DESCRIPTION

150       The  Cdk  histogram widget creates a histogram widget.  This widget can
151       draw a vertical or  horizontal  histogram.   The  functions  create  or
152       manipulate the Cdk histogram box widget.
153

AVAILABLE FUNCTIONS

155       activateCDKHistogram
156            obsolete entrypoint which calls drawCDKHistogram.
157
158       destroyCDKHistogram
159            removes  the  widget  from  the screen and frees memory the object
160            used.
161
162       drawCDKHistogram
163            draws the histogram widget on the screen.  If the box parameter is
164            true, the widget is drawn with a box.
165
166       eraseCDKHistogram
167            removes  the  widget  from  the screen.  This does NOT destroy the
168            widget.
169
170       getCDKHistogramBox
171            returns true if the widget will be drawn with a box around it.
172
173       getCDKHistogramFillerChar
174            returns the character being used to draw the histogram bar.
175
176       getCDKHistogramHighValue
177            returns the high value of the histogram.
178
179       getCDKHistogramLowValue
180            returns the low value of the histogram.
181
182       getCDKHistogramStatsAttr
183            returns the attribute of the statistics of the histogram.
184
185       getCDKHistogramStatsPos
186            returns where the histogram will draw the statistics.
187
188       getCDKHistogramValue
189            returns the current value of the histogram.
190
191       getCDKHistogramViewType
192            returns the view type of the histogram widget.
193
194       moveCDKHistogram
195            moves the given widget to the given position.  The parameters xpos
196            and  ypos  are the new position of the widget.  The parameter xpos
197            may be an integer or one of the pre-defined  values  TOP,  BOTTOM,
198            and  CENTER.   The  parameter ypos can be an integer or one of the
199            pre-defined values LEFT, RIGHT, and CENTER.  The  parameter  rela‐
200            tive  states  whether  the xpos/ypos pair is a relative move or an
201            absolute move.  For example if xpos = 1 and ypos = 2 and  relative
202            =  TRUE,  then  the widget would move one row down and two columns
203            right.  If the value of relative was FALSE then the  widget  would
204            move  to  the  position (1,2).  Do not use the values TOP, BOTTOM,
205            LEFT, RIGHT, or CENTER when relative = TRUE.   (weird  things  may
206            happen).   The  final  parameter  refresh is a boolean value which
207            states whether the widget will get refreshed after the move.
208
209       newCDKHistogram
210            creates a histogram widget and returns a pointer to  it.   Parame‐
211            ters:
212
213            screen
214                 is the screen you wish this widget to be placed in.
215
216            xpos controls  the  placement  of  the object along the horizontal
217                 axis.  It may be an integer or one of the pre-defined  values
218                 LEFT, RIGHT, and CENTER.
219
220            ypos controls the placement of the object along the vertical axis.
221                 It may be an integer or one of the  pre-defined  values  TOP,
222                 BOTTOM, and CENTER.
223
224            title
225                 is  the string which will be displayed at the top of the wid‐
226                 get.  The title can be more than one  line;  just  provide  a
227                 carriage return character at the line break.
228
229            height and
230
231            width
232                 control the height and width of the widget.  If you provide a
233                 value of zero for either of the height or the width, the wid‐
234                 get  will  be  created  with the full width and height of the
235                 screen.  If you provide a negative value, the widget will  be
236                 created the full height or width minus the value provided.
237
238            orient
239                 specifies  the  orientation  of  the histogram.  It is one of
240                 these pre-defined values: VERTICAL and HORIZONTAL.
241
242            label
243                 is the string to use as the label of the histogram.
244
245            box  is true if the widget should be drawn with a box around it.
246
247            shadow
248                 turns the shadow on or off around this widget.
249
250            If the widget  could  not  be  created  then  a  NULL  pointer  is
251            returned.
252
253       positionCDKHistogram
254            allows  the user to move the widget around the screen via the cur‐
255            sor/keypad keys.  See cdk_position (3) for key bindings.
256
257       setCDKHistogram
258            lets the programmer set the specific values of the histogram  wid‐
259            get.   The  parameter  viewType specifies the type of histogram to
260            draw.  The following table lists the valid values and the results.
