GrabStatus Gdk::Device::grab | ( | const Glib::RefPtr< Window >& | window, |
GrabOwnership | grab_ownership, | ||
bool | owner_events, | ||
EventMask | event_mask, | ||
const Glib::RefPtr< Cursor >& | cursor, | ||
guint32 | time_ | ||
) |
Grabs the device so that all events coming from this device are passed to this application until the device is ungrabbed with ungrab(), or the window becomes unviewable.
This overrides any previous grab on the device by this client.
Device grabs are used for operations which need complete control over the given device events (either pointer or keyboard). For example in GTK+ this is used for Drag and Drop operations, popup menus and such.
Note that if the event mask of an X window has selected both button press and button release events, then a button press event will cause an automatic pointer grab until the button is released. X does this automatically since most applications expect to receive button press and release events in pairs. It is equivalent to a pointer grab on the window with owner_events set to true
.
If you set up anything at the time you take the grab that needs to be cleaned up when the grab ends, you should handle the Gdk::EventGrabBroken events that are emitted when the grab ends unvoluntarily.
- Parameters:
-
window The Gdk::Window which will own the grab (the grab window). grab_ownership Specifies the grab ownership. owner_events If false
then all device events are reported with respect to window and are only reported if selected by event_mask. Iftrue
then pointer events for this application are reported as normal, but pointer events outside this application are reported with respect to window and only if selected by event_mask. In either mode, unreported events are discarded.event_mask Specifies the event mask, which is used in accordance with owner_events. cursor The cursor to display while the grab is active if the device is a pointer. If this is 0
then the normal cursors are used for window and its descendants, and the cursor for window is used elsewhere.time The timestamp of the event which led to this pointer grab. This usually comes from the Gdk::Event struct, though Gdk::CURRENT_TIME can be used if the time isn't known.
- Returns:
- Gdk::GRAB_SUCCESS if the grab was successful.

std::vector<std::string> Gdk::Device::list_axes | ( | ) | const |
Returns the labels for the axes that the device currently has.
std::vector<Glib::RefPtr<Gdk::Device> > Gdk::Device::list_slave_devices | ( | ) |
If the device if of type Gdk::DEVICE_TYPE_MASTER, it will return the list of slave devices attached to it, otherwise it will return 0
- Returns:
- The list of slave devices, or
0
. The list must be freed with Glib::list_free(), the contents of the list are owned by GTK+ and should not be freed.
void Gdk::Device::set_axis_use | ( | guint | index_, |
AxisUse | use | ||
) |
Specifies how an axis of a device is used.
- Parameters:
-
index The index of the axis. use Specifies how the axis is used.
void Gdk::Device::set_key | ( | guint | index_, |
guint | keyval, | ||
ModifierType | modifiers | ||
) |
Specifies the X key event to generate when a macro button of a device is pressed.
- Parameters:
-
index The index of the macro button to set. keyval The keyval to generate. modifiers The modifiers to set.
bool Gdk::Device::set_mode | ( | InputMode | mode | ) |
Sets a the mode of an input device.
The mode controls if the device is active and whether the device's range is mapped to the entire screen or to a single window.
- Parameters:
-
mode The input mode.
- Returns:
true
if the mode was successfully changed.
void Gdk::Device::ungrab | ( | guint32 | time_ | ) |
void Gdk::Device::warp | ( | const Glib::RefPtr< Screen >& | p1, |
int | x, | ||
int | y | ||
) |
Warps device in display to the point x, y on the screen screen, unless the device is confined to a window by a grab, in which case it will be moved as far as allowed by the grab.
Warping the pointer creates events as if the user had moved the mouse instantaneously to the destination.
Note that the pointer should normally be under the control of the user. This function was added to cover some rare use cases like keyboard navigation support for the color picker in the Gtk::ColorSelectionDialog.
- Parameters:
-
screen The screen to warp device to. x The X coordinate of the destination. y The Y coordinate of the destination.
