I'm trying to create a button in the application toolbar which when clicked displays a drop down menu. This is a custom screen with no ALV grid though so I can't use the ALV class methods. I create the button and fcode in my GUI status and set it when I call my custom screen but I can't find any way to turn it into a drop down menu. Is there any other way I can do it?
I thought I might be able to use the cl_gui_toolbar methods add_button and set_static_ctxmenu but I'm not sure how I'd get a reference to my running toolbar instance?
My code so far:
*----------------------------------------------------------------------*
*& Form f_handle_menu_button
*&---------------------------------------------------------------------*
* text
*----------------------------------------------------------------------*
FORM f_handle_menu_button.
DATA: go_toolbar TYPE REF TO cl_gui_toolbar,
go_menu TYPE REF TO cl_ctmenu.
CALL METHOD go_toolbar->add_button
EXPORTING
fcode = '&APPLY'
icon = ''
is_disabled = ''
butn_type = 1 "Pushbutton with Menu
text = 'Apply Status'.
CREATE OBJECT go_menu.
CALL METHOD go_menu->add_function
EXPORTING
fcode = '&STATUS1'
text = 'Status1'
icon = ' '
disabled = ' '
checked = ' '
hidden = ' '.
CALL METHOD go_menu->add_function
EXPORTING
fcode = '&STATUS2'
text = 'Status2'
icon = ' '
disabled = ' '
checked = ' '
hidden = ' '.
CALL METHOD go_toolbar->set_static_ctxmenu
EXPORTING
fcode = '&APPLY'
ctxmenu = go_menu.
ENDFORM. "F_HANDLE_MENU_BUTTON
Triggering a modal dialog from the application toolbar is simpler to implement and fits established UI patterns, such as selecting an ALV layout or selecting a financial, material, or purchasing document in those respective modules. And as you can see from the code, the signature of add_function is hardcoded to accept icons and text only.
As much as I would like to see this happen, I recommend using a modal dialog instead of a drop-down menu.
