Description

The WnckApplication is a group of WnckWindow that are all in the same application. It can be used to represent windows by applications, group windows by applications or to manipulate all windows of a particular application.

A WnckApplication is identified by the group leader of the WnckWindow belonging to it, and new WnckWindow are added to a WnckApplication if and only if they have the group leader of the WnckApplication.

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

Functions

wnck_application_get ()

WnckApplication *
wnck_application_get (gulong xwindow);

Gets the WnckApplication corresponding to the group leader with xwindow as X window ID.

Parameters

xwindow

the X window ID of a group leader.

 

Returns

the WnckApplication corresponding to xwindow , or NULL if there no such WnckApplication could be found. The returned WnckApplication is owned by libwnck and must not be referenced or unreferenced.

wnck_application_get_xid ()

gulong
wnck_application_get_xid (WnckApplication *app);

Gets the X window ID of the group leader window for app .

Parameters

app

a WnckApplication.

 

Returns

the X window ID of the group leader window for app .


wnck_application_get_name ()

const char *
wnck_application_get_name (WnckApplication *app);

Gets the name of app . Since there is no way to properly find this name, various suboptimal heuristics are used to find it. GTK+ should probably have a function to allow applications to set the _NET_WM_NAME property on the group leader as the application name, and the EWMH should say that this is where the application name goes.

Parameters

app

a WnckApplication.

 

Returns

the name of app , or a fallback name if no name is available.


wnck_application_get_icon_name ()

const char *
wnck_application_get_icon_name (WnckApplication *app);

Gets the icon name of app (to be used when app is minimized). Since there is no way to properly find this name, various suboptimal heuristics are used to find it.

Parameters

app

a WnckApplication

 

Returns

the icon name of app , or a fallback icon name if no icon name is available.


wnck_application_get_pid ()

int
wnck_application_get_pid (WnckApplication *app);

Gets the process ID of app .

Parameters

app

a WnckApplication.

 

Returns

the process ID of app , or 0 if none is available.


wnck_application_get_icon_is_fallback ()

gboolean
wnck_application_get_icon_is_fallback (WnckApplication *app);

Gets whether a default fallback icon is used for app (because none was set on app ).

Parameters

app

a WnckApplication

 

Returns

TRUE if the icon for app is a fallback, FALSE otherwise.


wnck_application_get_icon ()

GdkPixbuf *
wnck_application_get_icon (WnckApplication *app);

Gets the icon to be used for app . If no icon is set for app , a suboptimal heuristic is used to find an appropriate icon. If no icon was found, a fallback icon is used.

Parameters

app

a WnckApplication.

 

Returns

the icon for app . The caller should reference the returned GdkPixbuf if it needs to keep the icon around.

[transfer none]


wnck_application_get_mini_icon ()

GdkPixbuf *
wnck_application_get_mini_icon (WnckApplication *app);

Gets the mini-icon to be used for app . If no mini-icon is set for app , a suboptimal heuristic is used to find an appropriate icon. If no mini-icon was found, a fallback mini-icon is used.

Parameters

app

a WnckApplication.

 

Returns

the mini-icon for app . The caller should reference the returned GdkPixbuf if it needs to keep the mini-icon around.

[transfer none]


wnck_application_get_startup_id ()

const char *
wnck_application_get_startup_id (WnckApplication *app);

Gets the startup sequence ID used for startup notification of app .

Parameters

app

a WnckApplication.

 

Returns

the startup sequence ID used for startup notification of app , or NULL if none is available.

Since: 2.2


wnck_application_get_windows ()

GList *
wnck_application_get_windows (WnckApplication *app);

Gets the list of WnckWindow belonging to app .

Parameters

app

a WnckApplication.

 

Returns

the list of WnckWindow belonging to app , or NULL if the application contains no window. The list should not be modified nor freed, as it is owned by app .

[element-type WnckWindow][transfer none]


wnck_application_get_n_windows ()

int
wnck_application_get_n_windows (WnckApplication *app);

Gets the number of WnckWindow belonging to app .

Parameters

app

a WnckApplication.

 

Returns

the number of WnckWindow belonging to app .

Types and Values

WnckApplication

typedef struct _WnckApplication WnckApplication;

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