DESCRIPTION¶
These are utility functions that one may use to initialize, build or customize
widgets.
AVAILABLE FUNCTIONS¶
- CDKgetDirectoryContents
- opens and reads the contents of the given directory, filling the array
list with the sorted contents of the directory. If the directory
cannot be opened then it returns a value of -1.
- CDKreadFile
- Read the file filename, load the contents into a dynamically
allocated 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 format markers (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.
- 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
filename 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-terminated
array of chtype's string. A dynamically allocated string is
returned.
- deleteCursesWindow
- Safely delete a given window, i.e., first check if the window
parameter is nonnull.
- eraseCursesWindow
- Safely erase a given window, i.e., first check if the window
parameter 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 selected. 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
fieldWidth and a justification type justify, return the
number of characters 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 centered 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 widget:
- -
- If the proposed dimension proposedDim is FULL or zero, the return
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 CDKVIEWER 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 parameter. 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 buttonCount are applied to the CDKVIEWER
window.
