Function Documentation

CCIF void ctk_menu_add

(

struct ctk_menu *

menu

)

Add a menu to the menu bar.

Parameters

menu	The menu to be added.

Note

Do not call this function multiple times for the same menu, as no check is made to see if the menu already is in the menu bar.

Definition at line 504 of file ctk.c.

References ctk_menu::next, and NULL.

CCIF void ctk_menu_remove

(

struct ctk_menu *

menu

)

Remove a menu from the menu bar.

Parameters

menu	The menu to be removed.

Definition at line 532 of file ctk.c.

References ctk_menu::next, and NULL.

unsigned char ctk_mode_get

(

void

)

Retrieves the current CTK mode.

Returns

The current CTK mode.

Definition at line 291 of file ctk.c.

void ctk_mode_set

(

unsigned char

m

)

Sets the current CTK mode.

The CTK mode can be either CTK_MODE_NORMAL, CTK_MODE_SCREENSAVER or CTK_MODE_EXTERNAL. CTK_MODE_NORMAL is the normal mode, in which keypresses and mouse pointer movements are processed and the screen is redrawn. In CTK_MODE_SCREENSAVER, no screen redraws are performed and the first key press or pointer movement will cause the ctk_signal_screensaver_stop to be emitted. In the CTK_MODE_EXTERNAL mode, key presses and pointer movements are ignored and no screen redraws are made.

Parameters

m

The mode.

CCIF void ctk_window_clear

(

struct ctk_window *

w

)

Remove all widgets from a window.

Parameters

w	The window to be cleared.

Definition at line 485 of file ctk.c.

References ctk_window::active, ctk_window::focused, ctk_window::inactive, and NULL.

CCIF void ctk_window_close

(

struct ctk_window *

w

)

Close a window if it is open.

If the window is not open, this function does nothing.

Parameters

w	The window to be closed.

Definition at line 400 of file ctk.c.

References ctk_window::next, NULL, ctk_window::prev, and ctk_window::w.

CCIF void ctk_window_new	(	struct ctk_window *	window,
		unsigned char	w,
		unsigned char	h,
		char *	title
	)

Create a new window.

Creates a new window. The memory for the window structure must already be allocated by the caller, and is usually done with a static declaration.

This function sets up the internal structure of the ctk_window struct and creates the move and close buttons, but it does not open the window. The window must be explicitly opened by calling the ctk_window_open() function.

Parameters

window	The window to be created.
w	The width of the new window.
h	The height of the new window.
title	The title of the new window.

Definition at line 732 of file ctk.c.

CCIF void ctk_window_redraw

(

struct ctk_window *

w

)

Redraw a window.

This function redraws the window, but only if it is the foremost one on the desktop.

Parameters

w	The window to be redrawn.
