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.
