DESCRIPTION
The Cdk viewer widget creates a file viewer widget. This widget allows a user to interact with a file. It does NOT allow editing, this is view only. The following are functions which create or manipulate the Cdk viewer list widget.
AVAILABLE FUNCTIONS
- activateCDKViewer
- activates the viewer widget and lets the user interact with the widget. The parameter viewer is a pointer to a non-NULL viewer 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 a value from 0 to the number of buttons -1, representing the button selected. 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.
- cleanCDKViewer
- clears the information from the window.
- destroyCDKViewer
- removes the widget from the screen and frees memory the object used.
- drawCDKViewer
- draws the viewer widget on the screen. If the box option is true, the widget is drawn with a box.
- eraseCDKViewer
- removes the widget from the screen. This does NOT destroy the widget.
- getCDKViewerBox
- returns true if the widget will be drawn with a box around it.
- getCDKViewerHighlight
- returns the attribute of the buttons.
- getCDKViewerInfo
- returns the contents of the viewer widget.
- getCDKViewerInfoLine
- returns true if the information line is on.
- getCDKViewerTitle
- returns the title of the widget.
- moveCDKViewer
- function 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.
- *newCDKViewer
- function creates a viewer 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.
- height and
- width
- are the height and width of the viewer window.
- buttons
- is an array of the button labels which are to be attached to the viewer on the bottom.
- buttonCount
- is the number of buttons in buttons.
- buttonHighlight
- is the highlight attribute of the currently selected button.
- box

-
- If the widget could not be created then a NULL pointer is returned.
- positionCDKViewer
- allows the user to move the widget around the screen via the cursor/keypad keys. See cdk_position (3) for key bindings.
- setCDKViewer
- lets the programmer modify several elements of an existing viewer widget. The parameter title is the title to be displayed on the top of the viewer.
- The parameter list is the information to display, while listSize states how many rows there are in the list array. If listSize is negative, list is scanned to find its length, including files which will be included via embedded links.
- The parameter buttonAttribute states the attribute of the current highlighted button. The boolean parameter interpret tells the viewer to interpret the contents of list for Cdk display command. The showLineInfo boolean flag tells the viewer to show to show the line number and percentage in the top left corner of the viewer window. The parameters box and shadow are the same as in the function description of newCDKViewer.
- setCDKViewerBackgroundAttrib
- sets the background attribute of the widget. The parameter attribute is a curses attribute, e.g., A_BOLD.
