true if any events are pending. | static Event Gdk::Event::get | ( | ) | [static] |
Checks all open displays for a Gdk::Event to process,to be processed on, fetching events from the windowing system if necessary.
See Gdk::Display::get_event().
0 if no events are pending. The returned Gdk::Event should be freed with gdk_event_free(). | bool Gdk::Event::get_axis | ( | AxisUse | axis_use, | |
| double & | value | |||
| ) | const |
Extract the axis value for a particular axis use from an event structure.
| axis_use | The axis use to look for. | |
| value | Location to store the value found. |
true if the specified axis was found, otherwise false. | bool Gdk::Event::get_coords | ( | double & | x_win, | |
| double & | y_win | |||

Extract the event window relative x/y coordinates from an event.
| x_win | Location to put event window x coordinate. | |
| y_win | Location to put event window y coordinate. |
true if the event delivered event window coordinates. | static Event Gdk::Event::get_graphics_expose | ( | const Glib::RefPtr<Window>& | window | ) | [static] |
Waits for a GraphicsExpose or NoExpose event from the X server.
This is used in the Gtk::Text and Gtk::CList widgets in GTK+ to make sure any GraphicsExpose events are handled before the widget is scrolled.
| window | The Gdk::Window to wait for the events for. |
0 if a NoExpose event was received. | bool Gdk::Event::get_root_coords | ( | double & | x_root, | |
| double & | y_root | |||
| ) | const |
Extract the root window relative x/y coordinates from an event.

true if the event delivered root window coordinates. | Glib::RefPtr<const Screen> Gdk::Event::get_screen | ( | ) | const |
Returns the screen for the event.
The screen is typically the screen for event->any.window, but for events such as mouse events, it is the screen where the pointer was when the event occurs - that is, the screen which has the root window to which event->motion.x_root and event->motion.y_root are relative.
| Glib::RefPtr<Screen> Gdk::Event::get_screen | ( | ) |
Returns the screen for the event.
The screen is typically the screen for event->any.window, but for events such as mouse events, it is the screen where the pointer was when the event occurs - that is, the screen which has the root window to which event->motion.x_root and event->motion.y_root are relative.

Gets whether event debugging output is enabled.
true if event debugging output is enabled. | bool Gdk::Event::get_state | ( | ModifierType& | state | ) | const |
If the event contains a "state" field, puts that field in state .
Otherwise stores an empty state (0). Returns true if there was a state field in the event. event may be 0, in which case it's treated as if the event had no state field.
| state | Return location for state. |
true if there was a state field in the event. | guint32 Gdk::Event::get_time | ( | ) | const |
Returns the time stamp from event , if there is one; otherwise returns Gdk::CURRENT_TIME.

If there is an event waiting in the event queue of some open display, returns a copy of it.
See Gdk::Display::peek_event().

Appends a copy of the given event onto the front of the event queue for event->any.window's display, or the default event queue if event->any.window is 0.

| NativeWindow | winid | |||
| ) |
| bool Gdk::Event::send_client_message | ( | NativeWindow | winid | ) |
Sends an X ClientMessage event to a given window (which must be on the default Gdk::Display.
) This could be used for communicating between different applications, though the amount of data is limited to 20 bytes.
| winid | The window to send the X ClientMessage event to. |
| void Gdk::Event::set_screen | ( | const Glib::RefPtr<Screen>& | screen | ) |
Sets the screen for event to screen .
The event must have been allocated by GTK+, for instance, by gdk_event_copy().
| screen | A Gdk::Screen. |
| static void Gdk::Event::set_show_events | ( | bool | show_events | ) | [static] |
Sets whether a trace of received events is output.
Note that GTK+ must be compiled with debugging (that is, configured using the <option>--enable-debug</option> option) to use this option.
| show_events | true to output event debugging information. |
| void Gdk::Event::swap | ( | Event& | other | ) |
| lhs | The left-hand side |

| Gdk::Event wrap | ( | GdkEvent * | object, | |
