[Vm-dev] Add shortcut button on FileChooser dialog of Scratch 1.4

[Gustavo Duarte]

Hi folks,

I would like add a USB shortcut button on "Project Save As" File Chooser 
Dialog of Scratch 1.4 on Gnome.

I'm looking for a similar behavior that Scratch has on Sugar.

Currently File Chooser dialogue has myComputer, Home, Project directory 
short cuts,  I want add another one shortcut for USB.

I guess that I should modify

ScratchFileChooserDialog.addShortcutButtons method, but i'm not sure how.

I think the change needed could be like something that:

shortcutColumn addMorphBack: ( self shortcutButtonLabel: 	
                                self labelForUsbFolder
                                action: #usb
                                icon #folderUsb),

So, beside that, I have to add a kind of handler to the action, right ? 
How can I do that ?


Sorry if this kind of question isn't fit to this foro.

Thanks in advance.

Gustavo.
