DESCRIPTION¶
The Cdk histogram widget creates a histogram widget. This widget can draw a
vertical or horizontal histogram. The functions create or manipulate the Cdk
histogram box widget.
AVAILABLE FUNCTIONS¶
- 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. The parameters xpos
and ypos are the new position of the widget. The parameter
xpos may be an integer or one of the pre-defined values TOP,
BOTTOM, and CENTER. The parameter ypos can be an
integer or one of the pre-defined values LEFT, RIGHT, and
CENTER. 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). 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. Parameters:
- 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 values 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 values 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
returned.
- 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. 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. |
- The statsPosition parameter states where the statistics will be
displayed. It accepts TOP, BOTTOM, and CENTER.
- The parameter statsAttribute sets the attributes of the
statistics.
- The parameters lowValue, highValue, and currentValue
are the low, high, and current values respectively.
- The filler character is the character to use in the unused space in
the histogram.
- If the box parameter is true, the widget is drawn with a box.
- setCDKHistogramBackgroundAttrib
- the background color attribute the widget. The parameter attribute
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 setCDKHistogram
description for more details.
