AVAILABLE FUNCTIONS CDKchdir Change working directory to the given path, possibly expanding tilde (~) and wildcards (*). It returns zero on success. CDKgetDirectoryContents opens and reads the contents of the given directory, filling the array list with the sorted contents of the directory. If the di- rectory cannot be opened then it returns a value of -1. CDKopenFile Open the file, possibly expanding tilde (~) and wildcards (*). It returns a FILE pointer. CDKreadFile Read the file filename, load the contents into a dynamically allo- cated array, storing its address via info. It returns the number of lines read if the file could be opened, -1 otherwise. alignxy Aligns a box on the given window with the height and width given. See cdk_position (3) for the interpretation of the xpos, ypos, boxWidth and boxHeight, parameters. char2Chtype Translate a character string with embedded HTML-like format mark- ers (e.g., "</X/Y>Blah Blah") to a null-terminated array of chtype's. • The length of the array is stored via the length parameter. • The align parameter contains justification information (LEFT, CENTER, RIGHT). The caller is responsible for freeing the result. See cdk_display(3) for details on formatting. char2DisplayType Lookup the given name in string and return the equivalent display type. See also cdk_display(3). checkForLink Check if the given line is of the form <F=filename> If so, extract the filename from the line, storing it in the file- name buffer (which must hold at least CDK_PATHMAX characters). Return nonzero if a filename is extracted. chtype2String Extract the characters and formatting information from a null-ter- minated array of chtype's string. A dynamically allocated string is returned. See cdk_display(3) for details on Cdk's formatting. In addition, this function supports a feature needed to represent multi-line title strings returned by getCdkTitle (see cdk_objs(3)). Each newline separating lines in the title is rep- resented by "<#10>" to allow Cdk to display the string in a text field. deleteCursesWindow Safely delete a given window, i.e., first check if the window pa- rameter is nonnull. enableCursesMarkup Normally Cdk checks for HTML-like markup in character strings which it translates to curses strings with char2Chtype. Use this function to disable the feature temporarily. eraseCursesWindow Safely erase a given window, i.e., first check if the window para- meter is nonnull. getListIndex Display a scrollable list of strings in a dialog, allow the user to select one. Return the index in the list of the value se- lected. • The list parameter contains the strings to display; there are listSize strings in the list. • If numbers is true, the displayed list items will be numbered. getString pops up an entry widget with • a title supplied by the value of the title parameter, • a label supplied by the label parameter, and • an initial value supplied by the initialValue parameter. It returns a pointer to the value typed in or NULL if the widget was exited early. justifyString Given a string length mesglen, the available field width field- Width and a justification type justify, return the number of char- acters by which to shift the string. mode2Filetype Given a file protection mode fileMode, return ignoring the file- type bits, i.e., ignoring the corresponding permissions data. moveCursesWindow Move a given window by the amounts in xdiff and ydiff. popupDialog creates a quick pop-up dialog box. Pass in • the message in the mesg parameter, • the size of the message in the mesgCount parameter, • the button labels in the buttons parameter and • the number of buttons in the buttonCount parameter. The dialog box will be centered on the screen. popupLabel creates a quick pop-up label widget. The message and the size of the message are passed in via the mesg and count parameters respectively. The label widget waits until the user hits a character and is cen- tered on the screen. popupLabelAttrib Display a simple dialog with a list of count message strings mesg. Use the given attribute for the background of the dialog. selectFile Display a file-selection dialog. Return the selected filename, or null if none is selected. The caller should free the return- value. setWidgetDimension This is a helper function used to set the height/width of a wid- get: • If the proposed dimension proposedDim is FULL or zero, the re- turn value will be parentDim. • If the proposed dimension proposedDim is positive, • and it is larger than parentDim, return proposedDim, • otherwise return proposedDim plus adjustment. • If the proposed dimension proposedDim is negative, the return value will be parentDim plus proposedDim. • Otherwise, the return value will be proposedDim. stripWhiteSpace Strip whitespace from the front and/or back of the given string. The stripType parameter controls the type of stripping done: vFRONT, vBACK or vBOTH. viewFile Read the file specified by filename and display it in a CDKVIEWER window. The title, buttons and buttonCount are applied to the CD- KVIEWER window. • The viewer shows the contents of the file supplied by the filename value. • The buttons on the file viewer are supplied by the buttons pa- rameter. It returns the index of the button selected, or -1 if the file does not exist or if the widget was exited early. +-----------------+-------------------------------------+ | Strip_Type | Result | +-----------------+-------------------------------------+ +-----------------+-------------------------------------+ | vFRONT | This tells the function to remove | | | all of the white space from the | | | front of the given string. | +-----------------+-------------------------------------+ | vBACK | This tells the function to remove | | | all of the white space from the | | | back of the given string. | +-----------------+-------------------------------------+ | vBOTH | This tells the function to remove | | | all of the white space from both | | | the front and the back of the given | | | string. | +-----------------+-------------------------------------+ viewInfo Display the list of strings in info in a CDKVIEWER window. The number of strings is given by size. The title, buttons and but- tonCount are applied to the CDKVIEWER window.
