Set(menu ... ) command

Menu example This command used to manage a menu associated with the screen of the client.

Format

Set(menu,add|replace,_list_of_items_) or

Set(menu,clear)

Usage

Set(menu,add ...)

Command Set(menu,add ...) used to add items to the menu.

1=Set(menu,add,Item1,Item2,Item3)
2=ExecAndSet(menu,add,cat some_file.txt)

Set(menu,replace ...)

Command Set(menu,replace ...) used to replace items in the menu.

1=Set(menu,replace,Item1,Item2,Item3)
2=ExecAndSet(menu,add,cat some_file.txt)

There is a set of predefined menu items are associated with each screen of the client. These set of items will be added automatically during execution of Set(menu,replace ...) command.

Here is the sets of predefined items:

Controls (main) screen: List view screen: Text view screen: File manager screen (J2ME client only): Editfield screen: 
Exit
Disconnect
 
Back
 
Back
Wrap On (J2ME client only)
Wrap Off (J2ME client only)
Jump Up (J2ME client only)
Jump To End (J2ME client only)
 
Back
GoTo
Copy
Move
MkDir
Delete
View
Execute
File info
 
OK
Back

Set(menu,replace ...) command is not a superposition of Set(menu,clear) and Set(menu,add ...) commands because predefined menu items will be added only during Set(menu,replace ...). As a results, it is possible to omit predefined menu items by executing Set(menu,clear) and Set(menu,add ...) commands.

Set(menu,clear)

Command Set(menu,clear) used to remove all items from menu.

7=Set(menu,clear)

To avoid possible mess with menu, all menu items will be deleted each time client screen changed from one type to another (i.e. from Control (main) view to Text view). So, it is not necessary to issue Set(menu,clear) when client screen changed from one type to another. On another side it means what Set(menu ...) command should be executed after others Set(...) commands.
