.SH 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.
|
||
|
|
.SH AVAILABLE FUNCTIONS
|
||
|
|
.TP 5
|
||
|
|
.B activateCDKHistogram
|
||
|
|
obsolete entrypoint which calls \fBdrawCDKHistogram\fP.
|
||
|
|
.TP 5
|
||
|
|
.B destroyCDKHistogram
|
||
|
|

|
||
|
|

|
||
|
|

|
||
|

|
||
|
|
.TP 5
|
||
|
|
.B eraseCDKHistogram
|
||
|

|
This does \fINOT\fR destroy the widget.
|
||
|
|
.TP 5
|
||
|
|

||
|
|

|
||
|
|
.TP 5
|
||
|
|
.B getCDKHistogramFillerChar

||
|
|
returns the character being used to draw the histogram bar.
|
||
|
|
.TP 5
|
||
|
|
.B getCDKHistogramHighValue

||
|
|
.TP 5
|
||
|
|
.B getCDKHistogramLowValue
|
||
|
|
returns the low value of the histogram.
|
||
|
|
.TP 5
|
||
|
|
.B getCDKHistogramStatsAttr
|
||
|
|
returns the attribute of the statistics of the histogram.
|
||
|
|
.TP 5
|
||
|
|
.B getCDKHistogramStatsPos
|
||
|
|
returns where the histogram will draw the statistics.
|
||
|
|
.TP 5
|
||
|
|
.B getCDKHistogramValue
|
||
|
|
returns the current value of the histogram.
|
||
|
|
.TP 5
|
||
|
|
.B getCDKHistogramViewType
|
||
|
|
returns the view type of the histogram widget.
|
||
|
|
.TP 5
|
||
|
|
.B moveCDKHistogram
|
||
|
|
moves the given widget to the given position.
|
||
|
|
.RS
|
||
|
|
.bP
|
||
|
|
The parameters \fBxpos\fR and \fBypos\fR are the new position of the widget.
|
||
|
|
.bP
|
||
|
|
The parameter \fBxpos\fR may be an integer or one of the pre-defined values
|
||
|
|
\fITOP\fR, \fIBOTTOM\fR, and \fICENTER\fR.
|
||
|
|
.bP
|
||
|
|
The parameter \fBypos\fR can be an integer or one of the pre-defined values
|
||
|
|
\fILEFT\fR, \fIRIGHT\fR, and \fICENTER\fR.
|
||
|
|
.bP
|
||
|
|
The parameter \fBrelative\fR states whether
|
||
|
|
the \fBxpos\fR/\fBypos\fR pair is a relative move or an absolute move.
|
||
|
|
.IP
|
||
|
|
For example
|
||
|
|
if \fBxpos\fR = 1 and \fBypos\fR = 2 and \fBrelative\fR = \fBTRUE\fR,
|
||
|
|
then the widget would move one row down and two columns right.
|
||
|
|
If the value of \fBrelative\fR was \fBFALSE\fR then the widget would move to the position (1,2).
|
||
|
|
.IP
|
||
|
|
Do not use the values \fITOP\fR, \fIBOTTOM\fR, \fILEFT\fR,
|
||
|
|
\fIRIGHT\fR, or \fICENTER\fR when \fBrelative\fR = \fITRUE\fR.
|
||
|
|
(weird things may happen).
|
||
|
|
.bP
|
||
|
|
The final parameter \fBrefresh\fR is a boolean value which states
|
||
|
|
whether the widget will get refreshed after the move.
