[Fxruby-users] layout probs with TreeList.

[Hugh S. S. E. E. <hg...@dm...>]

I have an FXDialog window with a treelist created like this:



class CategoryDialog < FXDialogBox
    CATEGORIES = :CATEGORIES
    ITEMS = :ITEMS
    BOTH = :BOTH
    def initialize(parent, edit=CATEGORIES)
        super(parent, "Category Dialogue",DECOR_TITLE|DECOR_BORDER|LAYOUT_FILL_X)

        puts "called FXDialogBox.initialize"
        menubar = FXMenubar.new(self)
        filemenu = FXMenuPane.new(self)
        FXMenuCommand.new(filemenu, "&Quit", nil, getApp(), FXApp::ID_QUIT, 0)
        FXMenuTitle.new(menubar, "&File", nil, filemenu)

        FXHorizontalSeparator.new(self)
        # Contents
        contents = FXHorizontalFrame.new(self, LAYOUT_FILL_X )
        @treeview = Hash.new()
        @treeview[""] = FXTreeList.new(contents, 10)
        @treeview[""].listStyle |= TREELIST_SHOWS_LINES | TREELIST_SHOWS_BOXES | TREELIST_ROOT_BOXES|LAYOUT_FILL_X
        @treeview["equipment"] =
        @treeview[""].addItemLast(nil,
        "equipment",nil, # openIcon
        nil, # closedIcon
        TreeData.new(@treeview[""], "#{$equipdir}" ) # data
        )
    end

    #...
end

I find that the TreeList only takes up half the space of contents,
the lower pane, and that it is too narrow.  LAYOUT_FILL_X is not
doing what I expected in this regard.  Have I missed some layout
facilities?  Also the right hand half of contents is blank, despite
there being nothing in it: I thought it would expand to fit its
contents, which in this case would be not expand at all.
