The Cdk histogram widget creates a histogram widget. This widget can
draw a vertical or horizontal histogram. The functions create or ma-
nipulate the Cdk histogram box widget.
activateCDKHistogram
obsolete entrypoint which calls drawCDKHistogram.
destroyCDKHistogram
removes the widget from the screen and frees memory the object
used.
drawCDKHistogram
draws the histogram widget on the screen. If the box parameter
is true, the widget is drawn with a box.
eraseCDKHistogram
removes the widget from the screen. This does NOT destroy the
widget.
getCDKHistogramBox
returns true if the widget will be drawn with a box around it.
getCDKHistogramFillerChar
returns the character being used to draw the histogram bar.
getCDKHistogramHighValue
returns the high value of the histogram.
getCDKHistogramLowValue
returns the low value of the histogram.
getCDKHistogramStatsAttr
returns the attribute of the statistics of the histogram.
getCDKHistogramStatsPos
returns where the histogram will draw the statistics.
getCDKHistogramValue
returns the current value of the histogram.
getCDKHistogramViewType
returns the view type of the histogram widget.
moveCDKHistogram
moves the given widget to the given position.
o The parameters xpos and ypos are the new position of the
widget.
o The parameter xpos may be an integer or one of the pre-de-
fined values TOP, BOTTOM, and CENTER.
o The parameter ypos can be an integer or one of the pre-de-
fined values LEFT, RIGHT, and CENTER.
o The parameter relative states whether the xpos/ypos pair is
a relative move or an absolute move.
For example if xpos = 1 and ypos = 2 and relative = TRUE,
then the widget would move one row down and two columns
right. If the value of relative was FALSE, then the widget
would move to the position (1,2).
Do not use the values TOP, BOTTOM, LEFT, RIGHT, or CENTER
when relative = TRUE. (weird things may happen).
o The final parameter refresh is a boolean value which states
whether the widget will get refreshed after the move.
newCDKHistogram
creates a histogram widget and returns a pointer to it. Parame-
ters:
screen
is the screen you wish this widget to be placed in.
xpos controls the placement of the object along the horizontal
axis. It may be an integer or one of the pre-defined val-
ues LEFT, RIGHT, and CENTER.
ypos controls the placement of the object along the vertical
axis. It may be an integer or one of the pre-defined val-
ues TOP, BOTTOM, and CENTER.
title
is the string which will be displayed at the top of the
widget. The title can be more than one line; just provide
a carriage return character at the line break.
height and
width
control the height and width of the widget. If you provide
a value of zero for either of the height or the width, the
widget will be created with the full width and height of
the screen. If you provide a negative value, the widget
will be created the full height or width minus the value
provided.
orient
specifies the orientation of the histogram. It is one of
these pre-defined values: VERTICAL and HORIZONTAL.
label
is the string to use as the label of the histogram.
box is true if the widget should be drawn with a box around it.
shadow
turns the shadow on or off around this widget.
If the widget could not be created then a NULL pointer is re-
turned.
positionCDKHistogram
allows the user to move the widget around the screen via the
cursor/keypad keys. See cdk_position(3) for key bindings.
setCDKHistogram
lets the programmer set the specific values of the histogram
widget.
o The parameter viewType specifies the type of histogram to
draw. The following table lists the valid values and the
results.
+----------------+--------------------------------+
|Display_Type | Result |
+----------------+--------------------------------+
|vNONE | Displays no information about |
| | the current values. |
+----------------+--------------------------------+
|vPERCENT | Displays the current value as |
| | a percentage. |
+----------------+--------------------------------+
|vFRACTION | Displays the current value as |
| | a fraction. |
+----------------+--------------------------------+
|vREAL | Displays the current value. |
+----------------+--------------------------------+
o The statsPosition parameter states where the statistics will
be displayed. It accepts TOP, BOTTOM, and CENTER.
o The parameter statsAttribute sets the attributes of the sta-
tistics.
o The parameters lowValue, highValue, and currentValue are the
low, high, and current values respectively.
o The filler character is the character to use in the unused
space in the histogram.
o If the box parameter is true, the widget is drawn with a
box.
setCDKHistogramBackgroundAttrib
the background color attribute the widget. The parameter attri-
bute is a curses attribute, e.g., A_BOLD.
setCDKHistogramBackgroundColor
the background color of the widget. The parameter color is in
the format of the Cdk format strings. See cdk_display(3).
setCDKHistogramBox
sets whether the widget will be drawn with a box around it.
setCDKHistogramBoxAttribute
sets the attribute of the box.
setCDKHistogramDisplayType
sets the display type (see getCDKHistogramViewType).
setCDKHistogramFillerChar
sets the character to use when drawing the histogram bar.
setCDKHistogramHorizontalChar
sets the horizontal drawing character for the box to the given
character.
setCDKHistogramLLChar
sets the lower left hand corner of the widget's box to the given
character.
setCDKHistogramLRChar
sets the lower right hand corner of the widget's box to the
given character.
setCDKHistogramStatsAttr
sets the attribute to use when drawing the histogram statistics.
setCDKHistogramStatsPos
sets where the statistics will be drawn on the widget. See the
setCDKHistogram description for more details.
setCDKHistogramULChar
sets the upper left hand corner of the widget's box to the given
character.
setCDKHistogramURChar
sets the upper right hand corner of the widget's box to the
given character.
setCDKHistogramValue
sets the low, high, and current value of the histogram.
setCDKHistogramVerticalChar
sets the vertical drawing character for the box to the given
character.
setCDKHistogramViewType
sets the view type of the histogram. Look at the setCDKHis-
togram description for more details.
