fxruby users - Sep 2008 - Multiple feeds to one data target

Hi, folks -

Having some amazing fun with FXRuby, but not getting all the way there
despite Lyle''s docs and book.

Please see extracted example in DATA following __END__. I''m
constructing a
tab page of a block of TextFields plus sliders in construct_slider, but I
don''t have the info-passing correct yet. I can trigger the puts with
any
SEL_COMMAND, but I''m not getting data back. I don''t get the
value from the
#{@in_vals[ targ ].value }, nor do I get updated screen contents.

Please help an FXR noob get it right. All help appreciated!!!

__END__

class VMDemoWindow < FXMainWindow

  def initialize( app )

    image = VMImage.new( "wildebeest.jpg" )
    @in_vals = { :u_1     => FXDataTarget.new }
    super( app,
               "Statistics Tool",
                    :width => 550, :height => 450 )

    splitter = FXSplitter.new( self, :opts =>
SPLITTER_HORIZONTAL|LAYOUT_FILL )
    data_view = FXTabBook.new(splitter, :opts => LAYOUT_FILL )
    image_view = VMImageView.new( splitter, image )

    used_tab = FXTabItem.new( data_view, " % Used " )
    used_page = FXHorizontalFrame.new( data_view,
                                                        :opts =>
FRAME_RAISED | LAYOUT_FILL | PACK_UNIFORM_WIDTH )

    construct_used_page( used_page )

  end


  def construct_used_page( page )
    construct_slider( page, :u_1, "usage" )
  end


  def construct_slider( p, targ, str )

    s = FXVerticalFrame.new( p, :opts => FRAME_RAISED | LAYOUT_FILL )

    FXTextField.new( s, 3, :target => @in_vals[ targ ], :selector =>
FXDataTarget::ID_VALUE,
                            :opts => TEXTFIELD_NORMAL|LAYOUT_FILL_X )  do |
t |
      t.justify = JUSTIFY_CENTER_X | JUSTIFY_CENTER_Y
      t.tipText = "Value for " + str
    end

    FXSlider.new( s, @in_vals[ targ ], :selector => FXDataTarget::ID_VALUE,
                       :opts => SLIDER_VERTICAL | SLIDER_TICKS_LEFT |
LAYOUT_FILL ) do | aSlider |
      aSlider.range = Range.new( 1,.100 )
      aSlider.increment = 1
      aSlider.tickDelta = 10
      aSlider.tipText = "Value for " + str
      aSlider.height = 100
      aSlider.slotSize = 10
      aSlider.padTop = 10
      aSlider.padBottom = 10

    end

    @in_vals[ targ ].connect( SEL_COMMAND ) do | sender, sel, data |
      puts "\"#{ str }\" is now #{ @in_vals[ targ ].value
}."
    end

  end

end

I''ve had to make some substitutions since the code you sent
doesn''t
run (missing classes VMImage and VMImageFrame), but I think the main  
problem is that you never initialized the data target to any  
particular value. The main change I made was just to initialize it to  
0.5 (arbitrarily picked):

	@in_vals = {
		:u_1 => FXDataTarget.new(0.5)
	}

When I do this, both the text field and the slider start out with this  
value, and changing either the text field or slider value updates the  
data target''s value as expected.

Hope this helps,

Lyle

 Apologies. I stripped a lot more, should have left enough to let it run.
