Wimp_DecodeMenu
(SWI &400D5)
| Entry | |
|---|---|
| R1 | Pointer to menu data structure |
| R2 | Pointer to list of menu selections |
| R3 | Pointer to buffer for answer |
| Exit | |
|---|---|
| R0 | Corrupt |
Use
This call is incredibly useful to decode menus by their contents rather than their item selection numbers. For example, a returned value of Edit.Paste would be mean that the user has selected the ‘Paste’ item within the ‘Edit’ sub-menu.
Notes
Buffer pointed to by R3 is updated to contain menu item texts, separated by a period sign .
The string is terminated with a CR control code.
