Functions

gdk_app_launch_context_new ()

GdkAppLaunchContext *
gdk_app_launch_context_new (void);

gdk_app_launch_context_new has been deprecated since version 3.0 and should not be used in newly-written code.

Use gdk_display_get_app_launch_context() instead

Creates a new GdkAppLaunchContext.

Returns

a new GdkAppLaunchContext

Since: 2.14


gdk_app_launch_context_set_display ()

void
gdk_app_launch_context_set_display (GdkAppLaunchContext *context,
                                    GdkDisplay *display);

gdk_app_launch_context_set_display has been deprecated since version 3.0 and should not be used in newly-written code.

Use gdk_display_get_app_launch_context() instead

Sets the display on which applications will be launched when using this context. See also gdk_app_launch_context_set_screen().

Parameters

context

a GdkAppLaunchContext

 

display

a GdkDisplay

 

Since: 2.14


gdk_app_launch_context_set_screen ()

void
gdk_app_launch_context_set_screen (GdkAppLaunchContext *context,
                                   GdkScreen *screen);

Sets the screen on which applications will be launched when using this context. See also gdk_app_launch_context_set_display().

If both screen and display are set, the screen takes priority. If neither screen or display are set, the default screen and display are used.

Parameters

context

a GdkAppLaunchContext

 

screen

a GdkScreen

 

Since: 2.14


gdk_app_launch_context_set_desktop ()

void
gdk_app_launch_context_set_desktop (GdkAppLaunchContext *context,
                                    gint desktop);

Sets the workspace on which applications will be launched when using this context when running under a window manager that supports multiple workspaces, as described in the Extended Window Manager Hints.

When the workspace is not specified or desktop is set to -1, it is up to the window manager to pick one, typically it will be the current workspace.

Parameters

context

a GdkAppLaunchContext

 

desktop

the number of a workspace, or -1

 

Since: 2.14


gdk_app_launch_context_set_timestamp ()

void
gdk_app_launch_context_set_timestamp (GdkAppLaunchContext *context,
                                      guint32 timestamp);

Sets the timestamp of context . The timestamp should ideally be taken from the event that triggered the launch.

Window managers can use this information to avoid moving the focus to the newly launched application when the user is busy typing in another window. This is also known as 'focus stealing prevention'.

Parameters

context

a GdkAppLaunchContext

 

timestamp

a timestamp

 

Since: 2.14


gdk_app_launch_context_set_icon ()

void
gdk_app_launch_context_set_icon (GdkAppLaunchContext *context,
                                 GIcon *icon);

Sets the icon for applications that are launched with this context.

Window Managers can use this information when displaying startup notification.

See also gdk_app_launch_context_set_icon_name().

Parameters

context

a GdkAppLaunchContext

 

icon

a GIcon, or NULL.

[allow-none]

Since: 2.14


gdk_app_launch_context_set_icon_name ()

void
gdk_app_launch_context_set_icon_name (GdkAppLaunchContext *context,
                                      const char *icon_name);

Sets the icon for applications that are launched with this context. The icon_name will be interpreted in the same way as the Icon field in desktop files. See also gdk_app_launch_context_set_icon().

If both icon and icon_name are set, the icon_name takes priority. If neither icon or icon_name is set, the icon is taken from either the file that is passed to launched application or from the GAppInfo for the launched application itself.

Parameters

context

a GdkAppLaunchContext

 

icon_name

an icon name, or NULL.

[allow-none]

Since: 2.14

Types and Values

typedef struct _GdkAppLaunchContext GdkAppLaunchContext;
