New to FXRuby Can't justify a label

[Marlene Phillips]

I'm trying to wrap my head around Ruby, FXRuby, etc., getting back into
programming after 15+ years away.

Went through the Pragmatic Programmer tutorial chapters, now trying to
justify a label in a simple main window. I'm obviously missing something basic.

code is here:

require 'fox16'
include Fox

class Marlene1 < FXMainWindow
  def initialize(app)
    super(app, "Second window", :width=>600, :height=>400)
    label_icon = FXJPGIcon.new(app, File.open("mlp.jpg", "rb").read)
    label = FXLabel.new(self, "This is a label", :icon => label_icon,
      :opts => JUSTIFY_RIGHT|JUSTIFY_BOTTOM|ICON_BEFORE_TEXT)
    label2 = FXLabel.new(self, "sunken label", :opts => JUSTIFY_BOTTOM)
    show(PLACEMENT_SCREEN)
  end
end


if __FILE__ == $0
  FXApp.new do |app|
    Marlene1.new(app)
    app.create
    app.run
  end
end

No matter what I do, I can't get the label to the bottom of the window
(or any kind of justification, for that matter.) I put the icon in so I
could play with moving the label around. I tried
changing the height and width of the label, no luck. I tried creating
the label in an FXMatrix child window, and that was even worse - the
labels and icons
disappeared altogether until I resized the main window - then all of a
sudden they all appeared again, but still not justified.

What am I missing here? I'd sure appreciate help.

Thanks!

Some thoughts:

Height and width of the label do nothing unless you give the LAYOUT_FIX_WIDTH and/or LAYOUT_FIX_HEIGHT options.

You are not using a layout manager (FXVerticalFrame, etc.), so you get the default layout of the FXMainWindow which acts like a vertical frame stacking windows from the top left down.

Justification only applies within the labels height/width so it can't do anything if the FXLabel is auto sized to be only the size of its text (which is what is happening).  Try using LAYOUT_BOTTOM to move it to the bottom of the FXMainWindow.

Thanks so much for your help!  Follow up question: Any clues about why,
if I use the FXMatrix layout manager, I get a blank window at first, but
if I minimize or maximize the window, my icon and labels show up?

Thanks again,

Marlene
