Description

The WnckScreen represents a physical screen. A screen may consist of multiple monitors which are merged to form a large screen area. The WnckScreen is at the bottom of the libwnck stack of objects: WnckWorkspace objects exist a WnckScreen and WnckWindow objects are displayed on a WnckWorkspace.

The WnckScreen corresponds to the notion of GdkScreen in GDK.

The WnckScreen objects are always owned by libwnck and must not be referenced or unreferenced.

Details

struct WnckScreen

struct WnckScreen;

The WnckScreen struct contains only private fields and should not be directly accessed.

wnck_screen_get_default ()

WnckScreen *        wnck_screen_get_default             (void);

Gets the default WnckScreen on the default display.

Returns :

the default WnckScreen. The returned WnckScreen is owned by libwnck and must not be referenced or unreferenced. [transfer none]

wnck_screen_get ()

WnckScreen *        wnck_screen_get                     (int index);

Gets the WnckScreen for a given screen on the default display.

`index` :	screen number, starting from 0.
Returns :	the WnckScreen for screen `index`, or `NULL` if no such screen exists. The returned WnckScreen is owned by libwnck and must not be referenced or unreferenced. [transfer none]

wnck_screen_get_for_root ()

WnckScreen *        wnck_screen_get_for_root            (gulong root_window_id);

Gets the WnckScreen for the root window at root_window_id, or NULL if no WnckScreen exists for this root window.

This function does not work if wnck_screen_get() was not called for the sought WnckScreen before, and returns NULL.

`root_window_id` :	an X window ID.
Returns :	the WnckScreen for the root window at `root_window_id`, or `NULL`. The returned WnckScreen is owned by libwnck and must not be referenced or unreferenced. [transfer none]

wnck_screen_get_number ()

int                 wnck_screen_get_number              (WnckScreen *screen);

Gets the index of screen on the display to which it belongs. The first WnckScreen has an index of 0.

`screen` :	a WnckScreen.
Returns :	the index of `space` on `screen`, or -1 on errors.

Since 2.20

wnck_screen_get_width ()

int                 wnck_screen_get_width               (WnckScreen *screen);

Gets the width of screen.

`screen` :	a WnckScreen.
Returns :	the width of `screen`.

wnck_screen_get_height ()

int                 wnck_screen_get_height              (WnckScreen *screen);

Gets the height of screen.

`screen` :	a WnckScreen.
Returns :	the height of `screen`.

wnck_screen_force_update ()

void                wnck_screen_force_update            (WnckScreen *screen);

Synchronously and immediately updates the list of WnckWindow on screen. This bypasses the standard update mechanism, where the list of WnckWindow is updated in the idle loop.

This is usually a bad idea for both performance and correctness reasons (to get things right, you need to write model-view code that tracks changes, not get a static list of open windows). However, this function can be useful for small applications that just do something and then exit.

screen :

a WnckScreen.

wnck_screen_get_window_manager_name ()

const char *        wnck_screen_get_window_manager_name (WnckScreen *screen);

Gets the name of the window manager.

`screen` :	a WnckScreen.
Returns :	the name of the window manager, or `NULL` if the window manager does not comply with the EWMH specification.

Since 2.20

wnck_screen_net_wm_supports ()

gboolean            wnck_screen_net_wm_supports         (WnckScreen *screen,
                                                         const char *atom);

Gets whether the window manager for screen supports a certain hint from the Extended Window Manager Hints specification (EWMH).

When using this function, keep in mind that the window manager can change over time; so you should not use this function in a way that impacts persistent application state. A common bug is that your application can start up before the window manager does when the user logs in, and before the window manager starts wnck_screen_net_wm_supports() will return FALSE for every property.

See also gdk_x11_screen_supports_net_wm_hint() in GDK.

`screen` :	a WnckScreen.
`atom` :	a property atom.
Returns :	`TRUE` if the window manager for `screen` supports the `atom` hint, `FALSE` otherwise.

wnck_screen_get_active_window ()

WnckWindow *        wnck_screen_get_active_window       (WnckScreen *screen);

Gets the active WnckWindow on screen. May return NULL sometimes, since not all window managers guarantee that a window is always active.

`screen` :	a WnckScreen.
Returns :	the active WnckWindow on `screen`, or `NULL`. The returned WnckWindow is owned by libwnck and must not be referenced or unreferenced. [transfer none]

wnck_screen_get_previously_active_window ()

WnckWindow *        wnck_screen_get_previously_active_window
                                                        (WnckScreen *screen);

Gets the previously active WnckWindow on screen. May return NULL sometimes, since not all window managers guarantee that a window is always active.

`screen` :	a WnckScreen.
Returns :	the previously active WnckWindow on `screen`, or `NULL`. The returned WnckWindow is owned by libwnck and must not be referenced or unreferenced. [transfer none]

Since 2.8

wnck_screen_get_windows ()

GList *             wnck_screen_get_windows             (WnckScreen *screen);

Gets the list of WnckWindow on screen. The list is not in a defined order, but should be "stable" (windows should not be reordered in it). However, the stability of the list is established by the window manager, so don't blame libwnck if it breaks down.

`screen` :	a WnckScreen.
Returns :	the list of WnckWindow on `screen`, or `NULL` if there is no window on `screen`. The list should not be modified nor freed, as it is owned by `screen`. [element-type WnckWindow][transfer none]

wnck_screen_get_windows_stacked ()

GList *             wnck_screen_get_windows_stacked     (WnckScreen *screen);

Gets the list of WnckWindow on screen in bottom-to-top order.

`screen` :	a WnckScreen.
Returns :	the list of WnckWindow in stacking order on `screen`, or `NULL` if there is no window on `screen`. The list should not be modified nor freed, as it is owned by `screen`. [element-type WnckWindow][transfer none]

wnck_screen_get_active_workspace ()

WnckWorkspace *     wnck_screen_get_active_workspace    (WnckScreen *screen);

Gets the active WnckWorkspace on screen. May return NULL sometimes, if libwnck is in a weird state due to the asynchronous nature of the interaction with the window manager.

`screen` :	a WnckScreen.
Returns :	the active WnckWorkspace on `screen`, or `NULL`. The returned WnckWorkspace is owned by libwnck and must not be referenced or unreferenced. [transfer none]

wnck_screen_get_workspaces ()

GList *             wnck_screen_get_workspaces          (WnckScreen *screen);

Gets the list of WnckWorkspace on screen. The list is ordered: the first element in the list is the first WnckWorkspace, etc..

`screen` :	a WnckScreen.
Returns :	the list of WnckWorkspace on `screen`. The list should not be modified nor freed, as it is owned by `screen`. [element-type WnckWorkspace][transfer none]

Since 2.20

wnck_screen_get_workspace ()

WnckWorkspace *     wnck_screen_get_workspace           (WnckScreen *screen,
                                                         int workspace);

Gets the WnckWorkspace numbered workspace on screen.

`screen` :	a WnckScreen.
`workspace` :	a workspace index, starting from 0.
Returns :	the WnckWorkspace numbered `workspace` on `screen`, or `NULL` if no such workspace exists. The returned WnckWorkspace is owned by libwnck and must not be referenced or unreferenced. [transfer none]

wnck_screen_get_workspace_index ()

int                 wnck_screen_get_workspace_index     (WnckScreen *screen,
                                                         WnckWorkspace *space);

Warning

wnck_screen_get_workspace_index has been deprecated since version 2.20 and should not be used in newly-written code. Use wnck_workspace_get_number() instead.

Gets the index of space on screen. The first WnckWorkspace has an index of 0. See also wnck_workspace_get_number().

`screen` :	a WnckScreen.
`space` :	a WnckWorkspace.

                                                         WnckMotionDirection direction);

Warning

wnck_screen_get_workspace_neighbor has been deprecated since version 2.20 and should not be used in newly-written code. Use wnck_workspace_get_neighbor() instead.

Asks the window manager to change the number of WnckWorkspace on screen.

`screen` :	a WnckScreen.
`count` :	the number of WnckWorkspace to request.

Since 2.2

wnck_screen_try_set_workspace_layout ()

int                 wnck_screen_try_set_workspace_layout
                                                        (WnckScreen *screen,
                                                         int current_token,

                                                         int columns);

Tries to modify the layout of WnckWorkspace on screen. To do this, tries to acquire ownership of the layout. If the current process is the owner of the layout, current_token is used to determine if the caller is the owner (there might be more than one part of the same process trying to set the layout). Since no more than one application should set this property of screen at a time, setting the layout is not guaranteed to work.

If rows is 0, the actual number of rows will be determined based on columns and the number of WnckWorkspace. If columns is 0, the actual number of columns will be determined based on rows and the number of WnckWorkspace. rows and columns must not be 0 at the same time.

You have to release the ownership of the layout with wnck_screen_release_workspace_layout() when you do not need it anymore.

`screen` :	a WnckScreen.
`current_token` :	a token. Use 0 if you do not called `wnck_screen_try_set_workspace_layout()` before, or if you did not keep the old token.
`rows` :	the number of rows to use for the WnckWorkspace layout.
`columns` :	the number of columns to use for the WnckWorkspace layout.
Returns :	a token to use for future calls to `wnck_screen_try_set_workspace_layout()` and to `wnck_screen_release_workspace_layout()`, or 0 if the layout could not be set.

wnck_screen_release_workspace_layout ()

void                wnck_screen_release_workspace_layout
                                                        (WnckScreen *screen,
                                                         int current_token);

Releases the ownership of the layout of WnckWorkspace on screen. current_token is used to verify that the caller is the owner of the layout. If the verification fails, nothing happens.

`screen` :	a WnckScreen.
`current_token` :	the token obtained through `wnck_screen_try_set_workspace_layout()`.

struct WnckWorkspaceLayout

struct WnckWorkspaceLayout {
  int rows;

  int current_col;
};

Warning

WnckWorkspaceLayout has been deprecated since version 2.20 and should not be used in newly-written code.

The WnckWorkspaceLayout struct contains information about the layout of WnckWorkspace on a WnckScreen, and the exact position of a specific WnckWorkspace.

int `rows`;	number of rows in the layout grid.
int `cols`;	number of columns in the layout grid.
int *`grid`;	array of size `grid_area` containing the index (starting from 0) of the WnckWorkspace for each position in the layout grid, or -1 if the position does not correspond to any WnckWorkspace.
int `grid_area`;	size of the grid containing all WnckWorkspace. This can be bigger than the number of WnckWorskpace because the grid might not be filled.
int `current_row`;	row of the specific WnckWorkspace, starting from 0.
int `current_col`;	column of the specific WnckWorkspace, starting from 0.
