SIZE_CONTROL Event for docking container

Former Member — Mon, 17 Oct 2005 07:35:07 GMT

Hi, Everybody

I'm trying to handle size_control event for a docking container. But the event is not trigged. See the code excerpt below:


* Create left docking container
  CREATE OBJECT ao_docking_container_left
    EXPORTING
      side = cl_gui_docking_container=>dock_at_left
      extension = 300
      dynnr = cl_co=>ac_main_screen
      repid = cl_co=>ac_main_prog.


* Register the event
 ls_event-eventid = 12.
  ls_event-appl_event = 'X'.
  APPEND ls_event TO lt_events.

  CALL METHOD ao_docking_container_left->set_registered_events
    EXPORTING
      events                    = lt_events
    EXCEPTIONS
      cntl_error                = 1
      cntl_system_error         = 2
      illegal_event_combination = 3
      OTHERS                    = 4
          .
* Set handler
SET HANDLER handle_doclist_resize FOR ao_docking_container_left.

I have set the handle_doclist_resize method as a handler for the SIZE_CONTROL event of the CL_GUI_DOCKING_CONTAINER class (by Class Builder).

Hi,

Where is the class definition and implementation for handling that event?

All of it is the same global class.The code above is in the class constructor. Handle_doclist_resize is a handler method of the class.

I have transfered my code just into the one programm. But it still doesn't work I guess the SIZE_CONTROL event is not implemented in CL_GUI_DOCKING_CONTAINER.

See this code

* create the docking container
    CREATE OBJECT docking
                  EXPORTING repid     = repid
                            dynnr     = dynnr
                            side      = docking->dock_at_left
                            extension = 180.

This should be written in PBO of the screen.

See this sample code too <b>RSDEMO_DOCKING_CONTROL</b>.

Hi Mikola,

Docking Container Resize is a Controls Framework event and is handled inside CL_GUI_CFW class (HORIZONTAL_RESIZE method).

I do not think we will be able register for this event and hanlde it as Framewrk events are system events handled by CL_GUI_CFW.

try to register the event using method

REG_EVENT_SIZE_CONTROL of

CL_GUI_DOCKING_CONTAINER class.

I have tried to use both ways: (1) register the SIZE_CONTROL event particulary by calling REG_EVENT_SIZE_CONTROL method and (2) register it via events table.

May be, this event is not able to be registered because of its being handled by Control Framework (SIZE_CONTROL event is derived from CL_GUI_CONTROL class)???
