Select-options Code in WDDOINIT

[Former Member]

HI ,

The code which we put in the WDDOINIT metod is as follows

  l_ref_cmp_usage = wd_this->wd_cpuse_select_options( ).                " What is  WD_CPUSE

  IF l_ref_cmp_usage->has_active_component( ) IS INITIAL.                  "What is active component
    l_ref_cmp_usage->create_component( ).
  ENDIF.

  lr_interfacecontroller = wd_this->wd_cpifc_select_options( ).             " What is WD_CPIFC

  wd_this->m_select_options =
          lr_interfacecontroller->init_selection_screen( ).

could any one please explain what is happening actually with the above code

Hi,

the first three line

l_ref_cmp_usage = wd_this->wd_cpuse_select_options( ).               
 
  IF l_ref_cmp_usage->has_active_component( ) IS INITIAL.                  
    l_ref_cmp_usage->create_component( ).

of your code is creating the used component.

then this line

lr_interfacecontroller = wd_this->wd_cpifc_select_options( ).

is used to get a pointer to the interface controller of the select options component.

As the Select options component is already present,

HI Saini,

Then what is the CREATE we do in the Properties tab of the View

where we get something like below

SELECT_OPTIONS	WDR_SELECT_OPTIONS	                    
SELECT_OPTIONS	WDR_SELECT_OPTIONS	INTERFACECONTROLLER

Hi,

SELECT_OPTIONS	WDR_SELECT_OPTIONS	                    
SELECT_OPTIONS	WDR_SELECT_OPTIONS	INTERFACECONTROLLER

this means that we are re using the comp WDR_SELECT_OPTIONS in the view of your component.

to access all the methods of the component WDR_SELECT_OPTIONS we need to add it in the view which u want to use selection options methods

i.e you are using the method add_selection_field to populate the field on th screen.

to access this method we need to embed them in the view.
