Timeout

Description Before using GTK+, you need to initialize it; initialization connects to the window system display, and parses some standard command line arguments. The gtk_init() function initializes GTK+. gtk_init() exits the application if errors occur; to avoid this, use gtk_init_check(). gtk_init_check() allows you to recover from a failed GTK+ initialization - you might start up your application in text mode instead. Like all GUI toolkits, GTK+ uses an event-driven programming model. When the user is doing nothing, GTK+ sits in the main loop and waits for input. If the user performs some action - say, a mouse click - then the main loop "wakes up" and delivers an event to GTK+. GTK+ forwards the event to one or more widgets. When widgets receive an event, they frequently emit one or more signals. Signals notify your program that "something interesting happened" by invoking functions you've connected to the signal with g_signal_connect(). Functions connected to a signal are often termed callbacks. When your callbacks are invoked, you would typically take some action - for example, when an Open button is clicked you might display a GtkFileSelectionDialog. After a callback finishes, GTK+ will return to the main loop and await more user input. It's OK to use the GLib main loop directly instead of gtk_main(), though it involves slightly more typing. See GMainLoop in the GLib documentation.

Constructors

this this(uint interval, bool delegate() dlg, bool fireNow): Creates a new timeout cycle.

Destructor

~this ~this(): Removes the timeout from gtk

Members

Functions

addListener void addListener(bool delegate() dlg, bool fireNow): Adds a new delegate to this timeout cycle
stop void stop()

Static functions

add uint add(uint interval, GtkFunction funct, void* data): Warning gtk_timeout_add has been deprecated since version 2.4 and should not be used in newly-written code. Use g_timeout_add() instead. Registers a function to be called periodically. The function will be called repeatedly after interval milliseconds until it returns FALSE at which point the timeout is destroyed and will not be called again.
addFull uint addFull(uint interval, GtkFunction funct, GtkCallbackMarshal marshal, void* data, GDestroyNotify destroy): Warning gtk_timeout_add_full has been deprecated since version 2.4 and should not be used in newly-written code. Use g_timeout_add_full() instead. Registers a function to be called periodically. The function will be called repeatedly after interval milliseconds until it returns FALSE at which point the timeout is destroyed and will not be called again.
remove void remove(uint timeoutHandlerId): Warning gtk_timeout_remove has been deprecated since version 2.4 and should not be used in newly-written code. Use g_source_remove() instead. Removes the given timeout destroying all information about it.
timeoutCallback bool timeoutCallback(Timeout timeout): The callback execution from glib

Variables

timeoutID uint timeoutID;: our gtk timeout ID
timeoutListeners bool delegate()[] timeoutListeners;: Holds all timeout delegates
