在方法中获取按钮工具提示
Getting button tooltip in method
在我的 webdynpro 中,当我单击一个按钮时,我不想获取按钮的工具提示并将其用作 pop-up window.
的标题
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.
方法UI_GET_PROPERTY无法获取工具提示。可能是因为它试图在 if_wd_view_element 而不是 cl_wd_button 上调用方法 GET_TOOLTIP。这是此方法中的错误吗?
有没有办法将 if_wd_view_element 转换为 cl_wd_button?
ref to if_wd_view_element 可以向下转换为 ref to cl_wd_uielement。向下转换为 cl_wd_button 也适用于按钮,但不适用于工具栏按钮。 cl_wd_uielement 可能适用于所有 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.
