If both 'playback-time' and 'on-message' is specified, the action will be executed on whatever happens first. Possible types: `string` Default: (null) ## gtk-put-event ``` validate-scenario gtk-put-event, [keys=(string)], [string=(string)], [type=(string)], [widget-name=(string)], [playback-time=(double,string)]; ``` Put a GdkEvent on the event list using gdk_put_event * Implementer namespace: validategtk ### Parameters * `keys`:(optional): The keyboard keys to be used for the event, parsed with gtk_accelerator_parse_with_keycode, so refer to its documentation for more information Possible types: `string` Default: (null) * `string`:(optional): The string to be 'written' by the keyboard sending KEY_PRESS GdkEvents Possible types: `string` Default: (null) * `type`:(optional): The event type to get executed. the string should look like the ones in GdkEventType but without the leading 'GDK_'. It is not mandatory as it can be computed from other present fields (e.g, an action with 'keys' will consider the type as 'key_pressed' by default). Possible types: `string` Default: (null) * `widget-name`:(optional): The name of the target GdkWidget of the GdkEvent. That widget has to contain a GdkWindow. If not specified, the event will be sent to the first toplevel window Possible types: `string` Default: (null) * `playback-time`:(optional): The playback time at which the action will be executed Possible variables: * `position`: The current position in the stream * `duration`: The duration of the stream Possible types: `double,string` Default: 0.0 * `on-message`:(optional): Specify on what message type the action will be executed. If both 'playback-time' and 'on-message' is specified, the action will be executed on whatever happens first. Possible types: `string` Default: (null) ## set-subtitle ``` validate-scenario set-subtitle, subtitle-file=(string (A URI)), [playback-time=(double,string)]; ``` Action to set a subtitle file to use on a playbin pipeline. The subtitles file that will be used should be specified relative to the playbin URI in use thanks to the subtitle-file action property. You can also specify a folder with subtitle-dir For example if playbin.uri='file://some/uri.mov' and action looks like 'set-subtitle, subtitle-file=en.srt' the subtitle URI will be set to 'file:///some/uri.mov.en.srt' * Implementer namespace: validate-launcher ### Parameters * `subtitle-file`:(mandatory): Sets a subtitles file on a playbin pipeline Possible types: `string (A URI)` * `playback-time`:(optional): The playback time at which the action will be executed Possible variables: * `position`: The current position in the stream * `duration`: The duration of the stream Possible types: `double,string` Default: 0.0 * `on-message`:(optional): Specify on what message type the action will be executed. If both 'playback-time' and 'on-message' is specified, the action will be executed on whatever happens first. Possible types: `string` Default: (null)
