Class Gtk
public
class
Gtk
extends Object
This class is a catch-all for methods in GTK that are not associated with a
GTK object.
Method Summary |
static boolean | eventsPending()
Checks if any events are pending. |
static boolean | getFalse()
Analogical to {@link #getTrue}. |
static boolean | getTrue()
All this function does is to return TRUE. |
static void | init(String[] args)
This method should be called before using any java-gnome objects. |
static void | initCheck(String[] args)
This method does the same work as {@link #init} with only a single
change: It does not terminate the program if the GUI can't be
initialized. |
static boolean | isGtkThread()
Returns true if the current thread is the Gtk thread |
static void | main()
Runs the main event loop. |
static boolean | mainIteration()
Runs a single iteration of the main loop. |
static boolean | mainIterationDo(boolean blocking)
Runs a single iteration of the mainloop. |
static void | mainQuit()
Quit the main event loop. |
void | propagateEvent(Widget widget, Event event)
Sends an event to a widget, propagating the event to parent widgets if
the event remains unhandled.
|
static void | removeKeySnoopMethod()
Removes current the key snooper method. |
static void | setKeySnoopMethod(KeySnoopMethod method)
Installs a key snooper method, which will get called on all key events
before delivering them normally. |
public static boolean eventsPending()
Checks if any events are pending. This can be used to update the GUI and
invoke timeouts etc. while doing some time intensive computation.
Returns: true if any events are pending.
public static boolean getFalse()
Analogical to {@link #getTrue}. This function does nothing but always
return FALSE.
public static boolean getTrue()
All this function does is to return TRUE. This can be useful for example
if you want to inhibit the deletion of a window. Of course you should not
do this as the user expects a reaction from clicking the close icon of
the window.
public static void init(String[] args)
This method should be called before using any java-gnome objects. It
initialized everything needed to use the native libraries. This method
will terminate you program if it is unable to initialize the native
libraries.
Parameters: args
The command line arguments passed to the application.
public static void initCheck(String[] args)
This method does the same work as {@link #init} with only a single
change: It does not terminate the program if the GUI can't be
initialized. Instead it throws a {@link GtkInitException}.
Parameters: args
The command line arguments passed to the application.
Throws: GtkInitException
Since: 2.8.2
public static boolean isGtkThread()
Returns true if the current thread is the Gtk thread
public static void main()
Runs the main event loop.
public static boolean mainIteration()
Runs a single iteration of the main loop. If no events are waiting to be
processed GTK will block until the next event is noticed.
public static boolean mainIterationDo(boolean blocking)
Runs a single iteration of the mainloop. If no events are available
either return or block dependent on the value of
blocking.
Parameters: blocking
TRUE if you want GTK+ to block if no events are pending.
Returns: TRUE if {@link #mainQuit} has been called for the innermost
mainloop.
public static void mainQuit()
Quit the main event loop.
Sends an event to a widget, propagating the event to parent widgets if
the event remains unhandled.
NOTE: You most likely don't want to use this function.
Synthesizing events is rarely needed. Consider asking on the mailing list
for better ways to achieve your goals.
Parameters: widget
A Widget. event
An Event.
public static void removeKeySnoopMethod()
Removes current the key snooper method.
Installs a key snooper method, which will get called on all key events
before delivering them normally. This can be used to implement custom key
event handling.
