Changing button texts on internal pop-up window.

[ChrisPaine]

Hi -

I've not marked this a a question - as it is much more a rant, but if you have a suggestion, please do feel free to reply!

Why can I not change the text of buttons on an internal pop-up window?!

There is no API that I can find to update the text of the buttons.

The table in which the texts/buttons are stored is public in the class CL_WDR_INTERNAL_WINDOW, but marked as read only - so without enhancing the class I can't update the text.

I can understand the need to have consistency of appearance on applications - so having all popup windows with the same couple of buttons makes some sense ... and I can even understand the need to have some sort of restrictions to allow a unified rendering of the windows, but..even if I was still limited to have the same number of buttons as the standard constructor allows, then perhaps a method to allow me to change the text assigned to the button?

The alternative is that I choose the construct of no buttons and insert my own buttons in the view. But this looks ugly comparatively.

Why can't I make it look nice!

enought ranting - back to work

HI Chris,

I am not sure, but I think we can change The text of button in popup by using method

SUBSCRIBE_TO_BUTTON_EVENT in interface IF_WD_WINDOW

And you are soooo right! argghhhh! I was pulling my hair (what little I have left) out over this...

Can't believe I missed that...

DOH!

Thanks - sorry it's not a question so I can't mark it as answered.

Ok....

what's more you can do this registering of buttons within an freely programmed value help....

Which is great - because now I can make all my pop-ups have the same look and feel!

Here's a little code snippet from within a value help that I programmed to allow selection of a Job....

method wddoinit .
  data: lo_view type ref to if_wd_view_controller,
       lo_window_cntr type ref to if_wd_window_controller,
       lo_window type ref to if_wd_window,
       l_button_text type string.

  lo_view = wd_this->wd_get_api( ).

  lo_window_cntr = lo_view->get_embedding_window_ctlr( ).

  lo_window = lo_window_cntr->get_window( ).

  l_button_text =
     wd_assist->if_wd_component_assistance~get_text( '002' ). "Select Job

  lo_window->set_button_kind( if_wd_window=>co_buttons_okcancel ).

  lo_window->subscribe_to_button_event(
     button            = if_wd_window=>co_button_ok
     button_text       = l_button_text
     action_name       = 'JOB_SELECTED'
     action_view       = lo_view
     is_default_button = abap_true ).

  lo_window->subscribe_to_button_event(
      button            = if_wd_window=>co_button_cancel
      action_name       = 'CANCEL'
      action_view       = lo_view
      is_default_button = abap_false ).

endmethod.

Now my cancel and "Select Job" buttons are sitting all pretty in the bottom right corner of the popup...

Very nice!

NB both events have to close the window (or not depending on validation)

so need to call the value help listener's close_window method to exit the window -

seems the window was generated with the

close_in_any_case      = abap_false

parameter set. (default I believe is true.)

[ChrisPaine]

Alternatively I could just set it however I want using the

lo_window->set_close_in_any_case( abap_false ).

method.

Sometimes it seems that my new internal windows (freely programmed value helps) were having this set as true as default, and sometimes false. Can't figure out why - there will be a logical answer - but in the meantime the above bit of code ensures that they don't close the window on press of button - allows me to control when they should close.
