public class DesktopAppInfo extends Object
#GDesktopAppInfo is an implementation of #GAppInfo based on
desktop files.

Note that `<gio/gdesktopappinfo.h>` belongs to the UNIX-specific
GIO interfaces, thus you have to use the `gio-unix-2.0.pc` pkg-config
file when using it.

  • Constructor Details

    • DesktopAppInfo

      public DesktopAppInfo(PointerContainer pointer)

    • DesktopAppInfo

      public DesktopAppInfo(@Nonnull Str desktop_id)
      Creates a new #GDesktopAppInfo based on a desktop file id.

      A desktop file id is the basename of the desktop file, including the
      .desktop extension. GIO is looking for a desktop file with this name
      in the `applications` subdirectories of the XDG
      data directories (i.e. the directories specified in the `XDG_DATA_HOME`
      and `XDG_DATA_DIRS` environment variables). GIO also supports the
      prefix-to-subdirectory mapping that is described in the
      [Menu Spec](http://standards.freedesktop.org/menu-spec/latest/)
      (i.e. a desktop id of kde-foo.desktop will match
      `/usr/share/applications/kde/foo.desktop`).
      Parameters:
      desktop_id - the desktop file id

    • getShowIn

      public boolean getShowIn(@Nullable Str desktop_env)

      `OnlyShowIn` and `NotShowIn` keys.

      @desktop_env should typically be given as %NULL, in which case the
      `XDG_CURRENT_DESKTOP` environment variable is consulted. If you want
      to override the default mechanism then you may specify @desktop_env,
      but this is not recommended.

      Note that g_app_info_should_show() for @info will include this check (with
      %NULL for @desktop_env) as well as additional checks.
      Parameters:
      desktop_env - a string specifying a desktop name
      Returns:
      %TRUE if the @info should be shown in @desktop_env according to the `OnlyShowIn` and `NotShowIn` keys, %FALSE otherwise.

    • getShowIn

      public boolean getShowIn(String desktop_env)
      Checks if the application info should be shown in menus that list available

      `OnlyShowIn` and `NotShowIn` keys.

      @desktop_env should typically be given as %NULL, in which case the
      `XDG_CURRENT_DESKTOP` environment variable is consulted. If you want
      to override the default mechanism then you may specify @desktop_env,
      but this is not recommended.

      Note that g_app_info_should_show() for @info will include this check (with
      %NULL for @desktop_env) as well as additional checks.
      Parameters:

      WM_CLASS property of the main window of the application, if launched
      through @info.
      Returns:
      the startup WM class, or %NULL if none is set in the desktop file.

    • getString

      public Str getString(@Nonnull Str key)

      key - the key to look up
      Returns:
      %TRUE if the @key exists

    • launchAction

      public void launchAction(@Nonnull Str action_name, @Nullable AppLaunchContext launch_context)
      Activates the named application action.

      You may only call this function on action names that were
      returned from g_desktop_app_info_list_actions().

      Note that if the main entry of the desktop file indicates that the
      application supports startup notification, and @launch_context is
      non-%NULL, then startup notification will be used when activating the
      action (and as such, invocation of the action on the receiving side
      must signal the end of startup notification when it is completed).
      This is the expected behaviour of applications declaring additional
      actions, as per the desktop file specification.

      As with g_app_info_launch() there is no way to detect failures that
      occur while using this function.
      Parameters:
      action_name - the name of the action as from g_desktop_app_info_list_actions()
      launch_context - a #GAppLaunchContext

    • launchAction

      public void launchAction(String action_name, @Nullable AppLaunchContext launch_context)
      Activates the named application action.

      You may only call this function on action names that were
      returned from g_desktop_app_info_list_actions().

      Note that if the main entry of the desktop file indicates that the
      application supports startup notification, and @launch_context is
      non-%NULL, then startup notification will be used when activating the
      action (and as such, invocation of the action on the receiving side
      must signal the end of startup notification when it is completed).
      This is the expected behaviour of applications declaring additional
      actions, as per the desktop file specification.

      As with g_app_info_launch() there is no way to detect failures that
      occur while using this function.
      Parameters:
      action_name - the name of the action as from g_desktop_app_info_list_actions()
      launch_context - a #GAppLaunchContext

    • getImplementations

      public static List getImplementations(@Nonnull Str _interface)

      Returns:
      a list of #GDesktopAppInfo objects.
