DESCRIPTION
The Cdk matrix widget creates a matrix widget. The following are functions which create or manipulate the Cdk matrix box widget.
AVAILABLE FUNCTIONS
- activateCDKMatrix
- activates the matrix widget and lets the user interact with the widget. The parameter matrix is a pointer to a non-NULL matrix widget. If the actions parameter is passed with a non-NULL value, the characters in the array will be injected into the widget. To activate the widget interactively pass in a NULL pointer for actions. If the character entered into this widget is RETURN then this function will return 1. It will also set the widget data exitType to vNORMAL. If the character entered into this widget was ESCAPE then the widget will return a value of -1 and the widget data exitType will be set to vESCAPE_HIT. The matrix cell contents can be retrieved by using the info array of the matrix widget.
- cleanCDKMatrix
- clears the information from all cells of the matrix.
- cleanCDKMatrixCell
- clears the information from the specified cell of the matrix.
- destroyCDKMatrix
- removes the widget from the screen and frees memory the object used.
- drawCDKMatrix
- draws the matrix widget on the screen. If the box parameter is true, the widget is drawn with a box.
- eraseCDKMatrix
- removes the widget from the screen. This does NOT destroy the widget.
- getCDKMatrixBox
- returns true if the widget will be drawn with a box around it.
- getCDKMatrixCell
- returns the contents of the cell located by the row and col pair.
- getCDKMatrixCol
- returns the current column index.
- getCDKMatrixRow
- returns the current row index.
- injectCDKMatrix
- injects a single character into the widget. The parameter matrix is a pointer to a non-NULL matrix widget. The parameter character is the character to inject into the widget. The return value and side-effect (setting the widget data exitType) depend upon the injected character:
-
- RETURN or TAB
- the function returns 1. The widget data exitType is set to vNORMAL.
- ESCAPE
- the function returns -1. The widget data exitType is set to vESCAPE_HIT.
- Otherwise
- unless modified by preprocessing, postprocessing or key bindings, the function returns -1. The widget data exitType is set to vEARLY_EXIT.
-
- The matrix cell contents can be retrieved by using the info array of the matrix widget.
- jumpToCell
- provides an interactive method of moving to a cell. It pops up a scale widget and asks which cell the user wants to go to. Then it performs the jump.
- moveCDKMatrix
- 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 may 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.
- moveToCDKMatrixCell
- jumps to the given cells dictated by the parameters row and col. It returns a value of TRUE or FALSE depending if the move was successful.
- newCDKMatrix
- creates a matrix 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.
- screenRows and
- screenCols
- are the number of rows and columns to be displayed on the screen respectively.
- actualRows and
- actualCols
- are the number of actual rows and columns the matrix has.
- 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.
- rowTitles and
- colTitles
- are the titles along the row and columns respectively.
- columnWidths
- is an array of integers stating how wide the individual columns are to be.
- columnTypes
- is an array of integers which correspond to the individual column display types. The values of the array should be assigned a value of type EDisplayType. See cdk_display (3) for legal values of EDisplayType.
- rowSpace and
- colSpace
- dictate how much white space is to be between rows and columns respectively.
- filler
- is the character to use in empty space within a cell.
- dominantAttribute
- states which (the rows or the columns) will have the dominant character attributes. This is stated when a cell has both a row attribute and a column attribute. If the value of the parameter dominantAttribute is set to ROW then the attribute of the row will be displayed. If it is set to COL then the column's attributes will be displayed instead.
- boxMatrix
- is true if the widget should be drawn with a box around it.
- boxCell
- is true if the individual cells should have boxes drawn around them.
- shadow
- turns the shadow on or off around this widget.
-
- If the widget could not be created then a NULL pointer is returned.
- positionCDKMatrix
- allows the user to move the widget around the screen via the cursor/keypad keys. See cdk_position (3) for key bindings.
- setCDKMatrix
- lets the programmer modify certain elements of an existing matrix widget. The parameter info is an array of char * which contains the cell information. The parameter rows has the number of rows the parameter info contains, while columnLengths has the lengths of the individual columns in info.
- Do not use this function. It is obsolete, provided only for compatibility with older versions of CDK. Use setCDKMatrixCells.
- setCDKMatrixBackgroundAttrib
- sets the background attribute of the widget. The parameter attribute is a curses attribute, e.g., A_BOLD.
- setCDKMatrixBackgroundColor
- sets the background color of the widget. The parameter color is in the format of the Cdk format strings. See cdk_display (3).
- setCDKMatrixBox
- sets whether the widget will be drawn with a box around it.
- setCDKMatrixBoxAttribute
- sets the attribute of the box.
- setCDKMatrixCB
- allows the programmer to set a different widget input handler. The parameter callbackFunction is of type MATRIXCB. The default function is CDKMatrixCallBack.
- setCDKMatrixCell
- sets the contents of the cell located by the row and col pair. The value of the cell will be set to value.
- setCDKMatrixCells,
- lets the programmer initialize elements of an existing matrix widget. The parameter info is an array of char * which contains the cell information. The parameter rows has the number of rows The parameter cols has the number of columns the parameter info contains, while columnLengths has the lengths of the individual columns in info.
- setCDKMatrixHorizontalChar
- sets the horizontal drawing character for the box to the given character.
- setCDKMatrixLLChar
- sets the lower left hand corner of the widget's box to the given character.
- setCDKMatrixLRChar
- sets the lower right hand corner of the widget's box to the given character.
- setCDKMatrixPostProcess
- allows the user to have the widget call a function after the key has been applied to the widget. The parameter function is the callback function. The parameter data points to data passed to the callback function. To learn more about post-processing see cdk_process (3).
- setCDKMatrixPreProcess
- allows the user to have the widget call a function after a key is hit and before the key is applied to the widget. The parameter function is the callback function. The parameter data points to data passed to the callback function. To learn more about pre-processing see cdk_process (3).
- setCDKMatrixULChar
- sets the upper left hand corner of the widget's box to the given character.
- setCDKMatrixURChar
- sets the upper right hand corner of the widget's box to the given character.
- setCDKMatrixVerticalChar
- sets the vertical drawing character for the box to the given character.
KEY BINDINGS
When the widget is activated there are several default key bindings which will help the user enter or manipulate the information quickly. The following table outlines the keys and their actions for this widget.
