In my webdynpro, when I click a button, I wan't to get the tooltip of the button and use it as the title of the pop-up window.
method WDDOMODIFYVIEW .
"write view to attribute so it can be accessed from other methods.
wd_this->DETAILVIEW = view.
endmethod.
.
method ONACTIONOPENDIALOG .
data lv_title type string.
data lv_buttonID type string.
data lv_button type ref to if_wd_view_element.
buttonID = wdevent->get_string( name = 'ID' ).
button = wd_this->detailview->get_element( lv_buttonid ).
call method cl_fitv_wd_util=>UI_GET_PROPERTY(
exporting
io_view = wd_this->detailview
io_view_element = lv_button
iv_id = buttonid
iv_property_name = 'TOOLTIP'
importing
ev_value = lv_title ).
wd_this->dopopup( title = lv_title ).
endmethod.
The method UI_GET_PROPERTY fails to get the tooltip. Probably because it's trying to call the method GET_TOOLTIP on if_wd_view_element and not on cl_wd_button. Is this a bug in this method? Is there a way to convert if_wd_view_element to cl_wd_button?
ref to if_wd_view_element can be downcasted to ref to cl_wd_uielement. Downcasting to cl_wd_button works aswell for buttons, but not for toolbar buttons. cl_wd_uielement works for probably all uielements.
method ONACTIONOPENDIALOG .
data lv_title type string.
data lv_buttonID type string.
data lv_button type ref to if_wd_view_element.
data lv_realbutton type ref to cl_wd_uielement.
lv_buttonID = wdevent->get_string( name = 'ID' ).
lv_button = wd_this->detailview->get_element( lv_buttonid ).
"downcast view_element to uielement
lv_realbutton ?= lv_button.
lv_title = lv_realbutton->get_tooltip( ).
selectbuttonrow( exporting actionevent = wdevent ).
wd_this->dopopup( title = lv_title ).
endmethod.
I found an article about downcasting here: https://help.sap.com/doc/abapdocu_750_index_htm/7.50/en-US/abapmove_cast.htm
