DESCRIPTION

AVAILABLE FUNCTIONS

destroyCDKScreen

frees any memory allocated by the Cdk screen pointer.

endCDK

cleans up any memory created by starting Cdk and shuts down curses.

eraseCDKScreen

erases all of the widgets which are currently associated to the given screen. This does NOT destroy the widgets.

initCDKColor

starts the Cdk color capabilities. It defines 64 color pairs each of which is accessible using the COLOR_PAIR macro. If you do not have color support, this function call makes no difference.

initCDKScreen

takes a WINDOW* parameter cursesWindow and returns a pointer to a CDKSCREEN.

Since all of the widgets take a CDKSCREEN pointer as a first argument, this is one of the first calls made.

If the cursesWindow parameter is a null pointer, initCDKScreen initializes curses and replaces the parameter with stdscr. Otherwise, it assumes that your application has already initialized the locale and then called initscr

In either case, the (possibly updated) cursesWindow parameter is used as the window for the CDKSCREEN result.

lowerCDKObject

has the opposite effect of the raiseCDKObject function call.

raiseCDKObject

raises the widget to the top of the screen. If there are any widgets which overlap the given object when a refresh is done, calling this function has the effect of raiding the object so no other widgets obstruct it.

refreshCDKScreen

redraws all of the widgets which are currently associated to the given screen.

registerCDKObject

is called automatically when a widget is created. If for some reason an object does get unregistered, by calling unregisterCDKObject, the widget can be registered again by calling this function.

unregisterCDKObject

removes the widget from the screen. This does NOT destroy the object, it removes the widget from any further refreshes by the function refreshCDKScreen.
