Unlucky in using self~constDir[SYMBOLIC_ID] = numericID I changed
all Symbolic IDs in the example within paragraph 23.2.3.2
'SystemMenu Command Event Handler' on page 1155f of 'ooDialog
Reference Version 4.2.0' to numeric IDs from 301 up to 309 (hoping
not to step over some predefined constants - BTW, how may I figure
out what numeric IDs are not yet in use?).
The addition to the system menu is shown as expected, alas only
selecting the menu entry 'Cut' brings the expected result, 'Copy'
and 'Paste' just make the menu disappear but nothing more. When I
quit the dialog the cmd window shows two lines:
In uninit() of PopupMenu
In UNINIT() of Menu class cMenu=01782EA0
where the value of cManu changes for every run: 01CD2E48,
01CD2EA0, 02012EA0, 01D62EA0, 01D62EA0, 01782EA0. Looks like a
damaged error message.
What did I overlook this time? As a beginner within ooREXX and
ooDialog I allow me to append what I tried.
Best,
M.
