Re: Re: [Fxruby-users] Default associations in FXFileList and FXDirList

[Kristoffer Lund <kun...@ho...>]

Thanks a lot! I'll try it out when I have the possibility. I'm sitting on w=
ebmail at a school at the moment, hoping to be up and running with my own=
 computer soon again...

Will tell you how it went. Thanks!

Jeroen: Kristoffer is absolutely correct, there is a bug in the=20
FXDirList widget, at least for the fox-1.0.x series. Have not checked it=20
on fox-1.1.x. The problem is that if you call FXDirList::setDirectory()=20
before calling create() on the directory list widget, the call to=20
scanRootDir() in FXDirList::create() blows away the previous tree structure=
.

Kristoffer: Based on that, the workaround for your program is to first=20
save a reference to the directory list in an instance variable after=20
constructing it, i.e.

     @dirlist =3D FXDirList.new(...)

and then set the directory in your MainWindow#create method, *after*=20
calling the base class version of create(), i.e.

     class MainWindow
       def create
         # Do base class create first
         super

         # Now set the desired directory
         @dirlist.directory =3D 'D:\\music'

         # and show the main window
         show(PLACEMENT_SCREEN)
       end
     end

Hope this helps,

Lyle
