Hey, two questions:

can Scratch create a FOLDER on your computer using smalltalk and is there a way to create a costume with a chosen text, font, size and colour?

Thanks!

No. I mean smalltalk. An edited version of Scratch (Panther really) should be able to do these things with smalltalk. Squeak is the VM.

I know. But you said 'Scratch'. OH never mind. tongue

Yes. It would be. I was actually reading about this. Lemme find it....

It can create a new folder. I'll look for the code.

ProgrammingFreak · 2011-04-20 14:39:30

Code:

aStream := aFilenameString asFilename writeStream

That's the setup for it.

johnnydean1 · 2011-04-20 14:51:21

Look at this:

UIDialogs-FilePicker-private-newDirectiory
newDirectory
| t1 |
t1 _ StringDialog askWithCancel: 'New folder name:'.
t1 = '' ifTrue: [^ self].
[self currentDirectory createDirectory: t1]
ifError: [:t2 :t3 | ^ DialogBoxMorph warn: 'Could not create folder.'].
self currentDirectory: self currentDirectory

Why not have it as a CustomDialog?

I dunno, but thats what scratch uses!

Oh, so scratch can make files?

Scratch can make files. Remember the little scratchthumb files that appear in folders when you view it through Scratch?

Thats your folder problem sorted then!!!

It looks good - didn't work as a custom block though...

Read how it works. The currentDirectory needs setting.

sparks · 2011-04-20 16:21:03

currentDirectory appears to be an "already in use" variable. I can't set it or declare it.

bbbeb · 2011-04-20 16:22:10

its the programs current directory.

tongue

johnnydean1 · 2011-04-20 16:25:05

Ill let you discuss this. I don't get how it works.

hm... then how come the block won't currently work? It gives me the syntax error:

Code:

| t1 |
t1 _ 'test'.
UIDialogs-FilePicker-private-newDirectiory
newDirectory
    | t1|
    t1 Nothing more expected ->_ StringDialog askWithCancel: 'New folder name:'.
    t1 = '' ifTrue: [^ self].
    [self currentDirectory createDirectory: t1]
        ifError: [:t2 :t3 | ^ DialogBoxMorph warn: 'Could not create folder.'].
    self currentDirectory: self currentDirectory

This is the problem?

Code:

t1 _ StringDialog askWithCancel: 'New folder name:'.

1. Destroy the
t1_ 'test'.
You dont need that.
2. You declared t1 twice,
that may cause syntax problems.

t1 is only declared once and never set to 'test' if you look at the actual block code:

Code:

UIDialogs-FilePicker-private-newDirectiory
newDirectory
    | t1|
    t1 _ StringDialog askWithCancel: 'New folder name:'.
    t1 = '' ifTrue: [^ self].
    [self currentDirectory createDirectory: t1]
        ifError: [:t2 :t3 | ^ DialogBoxMorph warn: 'Could not create folder.'].
    self currentDirectory: self currentDirectory

johnnydean1 · 2011-04-21 03:43:51

It is not the current directory of the Scratch project. When you are in a file browser window, the directory your looking at is the currentDirectory.

Win32 C++ is a real pain!
It's all illogical, you're better of learning the .NET version if you want to keep your sanity.
