Scratch

Okay, So I have the following block that I've created;

Blockspec:

Code:

('Right Click Menu %s %s %s'    r    rightButtonMenu2:opt2:opt3: 'opt1' 'opt2' 'opt3')

Method:

Code:

rightButtonMenu2: t1 opt2: t2 opt3: t3
    | menu |
    menu _ CustomMenu new.
    menu add: t1 action: t1.
    menu add: t2 action: t2.
    menu add: t3 action: t3.
    ^ menu startUp: #test

My question is, how do I make the reporter report a blank string instead of 'nil' when the user clicks off the menu without selecting an option?

I haven't modded Scratch in a while, but something like this might work:

Code:

test isNil
    ifTrue: [^ '']
    ifFalse: [^ test].

Replace "test" with the variable that contains the menu item that was clicked.

Returning from blocks is no fun! tongue

| menu result |
"..."
result := menu startUp: #test.
^ result ifNil: [''] ifNotNil: [result]

This might sound silly, but how do I set each menu option to define said variable?

nXIII answered your question. Here's the code pieced together:

Code:

rightButtonMenu2: t1 opt2: t2 opt3: t3
    | menu result |
    menu _ CustomMenu new.
    menu add: t1 action: t1.
    menu add: t2 action: t2.
    menu add: t3 action: t3.
    result _ menu startUp: #test.
    ^ result ifNil: [''] ifNotNil: [result]
