This widget can draw a vertical or horizontal histogram. The functions create or ma- nipulate 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. o The parameters xpos and ypos are the new position of the wid- get. o The parameter xpos may be an integer or one of the pre-defined values TOP, BOTTOM, and CENTER. o The parameter ypos can be an integer or one of the pre-defined 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 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 wid- get. 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 wid- get 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 cur- sor/keypad keys. See cdk_position (3) for key bindings. setCDKHistogram lets the programmer set the specific values of the histogram wid- get. o The parameter viewType specifies the type of histogram to draw. The following table lists the valid values and the re- sults. +----------------+--------------------------------+ |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 char- acter. setCDKHistogramViewType sets the view type of the histogram. Look at the setCDKHistogram description for more details. SEE ALSO cdk(3), cdk_binding(3), cdk_display(3), cdk_position(3), cdk_screen(3) cdk_histogram(3)
