AppLaunchContext

gdk.app_launch_context.AppLaunchContext handles launching an application in a graphical context.

It is an implementation of gio.app_launch_context.AppLaunchContext that provides startup notification and allows to launch applications on a specific workspace.

Launching an application

GdkAppLaunchContext *context;

context = gdk_display_get_app_launch_context (display);

gdk_app_launch_context_set_timestamp (gdk_event_get_time (event));

if (!g_app_info_launch_default_for_uri ("http://www.gtk.org", context, &error))
  g_warning ("Launching failed: %s\n", error->message);

g_object_unref (context);

class AppLaunchContext : AppLaunchContext {

gdk.display.Display getDisplay();

void setDesktop(int desktop);

void setIcon(gio.icon.Icon icon);

void setIconName(string iconName);

void setTimestamp(uint timestamp);

}

From AppLaunchContext

getDisplay string getDisplay(gio.app_info.AppInfo info, gio.file.File[] files): Gets the display string for the context. This is used to ensure new applications are started on the same display as the launching application, by setting the DISPLAY environment variable.
getEnvironment string[] getEnvironment(): Gets the complete environment variable list to be passed to the child process when context is used to launch an application. This is a null-terminated array of strings, where each string has the form KEY=VALUE.
getStartupNotifyId string getStartupNotifyId(gio.app_info.AppInfo info, gio.file.File[] files): Initiates startup notification for the application and returns the XDG_ACTIVATION_TOKEN or DESKTOP_STARTUP_ID for the launched operation, if supported.
launchFailed void launchFailed(string startupNotifyId): Called when an application has failed to launch, so that it can cancel the application startup notification started in gio.app_launch_context.AppLaunchContext.getStartupNotifyId.
setenv void setenv(string variable, string value): Arranges for variable to be set to value in the child's environment when context is used to launch an application.
unsetenv void unsetenv(string variable): Arranges for variable to be unset in the child's environment when context is used to launch an application.
connectLaunchFailed ulong connectLaunchFailed(T callback, Flag!"After" after): Connect to LaunchFailed signal.
connectLaunchStarted ulong connectLaunchStarted(T callback, Flag!"After" after): Connect to LaunchStarted signal.
connectLaunched ulong connectLaunched(T callback, Flag!"After" after): Connect to Launched signal.
