wxruby users - Nov 2004 - Layout Issue ...

The following program represents the basic layout of my application. The 
problem I have is that the panel, and thus, the grid does not resize 
when the window width is expanded.

Also, I would like the entire grid to be displayed without the 
horizontal scroll bar. How can I force this behavior?

Please tell me if I am going about this incorrectly. I am just getting 
familar with wxRuby and any advice is appreciated.

# CODE STARTS HERE ....

require ''wxruby''

class TestApp < Wx::App
    def on_init
    @frame = Wx::Frame.new( nil, -1, "Test", Wx::DEFAULT_POSITION )

    @panel = Wx::Panel.new( @frame )
    
    @topSizer = Wx::FlexGridSizer.new( 1, 3 )
    @topSizer.add( createInputSizer(), 1, Wx::GROW|Wx::ALL, 2 )
    @topSizer.add( createGridSizer(), 1, Wx::GROW|Wx::ALL, 2 )
    @topSizer.add( createButtonSizer(), 1, 
Wx::ALIGN_CENTER_HORIZONTAL|Wx::ALL, 2 )
    
    @panel.set_sizer( @topSizer )
    @topSizer.fit( @frame )

    @frame.show
    self.main_loop    
    end

    def createButtonSizer
    @buttonSizer = Wx::BoxSizer.new( Wx::HORIZONTAL )
    
    @btn1 = Wx::Button.new(@panel, -1, ''Button 1'')
    @buttonSizer.add(@btn1, 0, Wx::ALIGN_CENTER_VERTICAL|Wx::ALL, 2)
    
            
    @btn2 = Wx::Button.new(@panel, -1, ''Print'')
    @buttonSizer.add(@btn2, 0, Wx::ALIGN_CENTER_VERTICAL|Wx::ALL, 2)
    
    @buttonSizer
    end

    def createGridSizer
    @gridSizer = Wx::BoxSizer.new( Wx::VERTICAL )
    
    @grid = Wx::Grid.new( @panel, -1, Wx::Point.new( 1, 1 ), 
Wx::Size.new( 500, 350 ) )

    @grid.create_grid( 15, 7 )

    @gridSizer.add( @grid, 1, Wx::GROW|Wx::ALL, 5 )

    @gridSizer
    end

    def createInputSizer
    @inputSizer = Wx::FlexGridSizer.new( 4, 3 )
    
    st1 = Wx::StaticText.new( @panel, -1, "Text:" )
    @inputSizer.add( st1, 0, 
Wx::ALIGN_CENTER_HORIZONTAL|Wx::ALIGN_CENTER_VERTICAL|Wx::ALL|Wx::ADJUST_MINSIZE,
5 )
    
    @text1 = Wx::TextCtrl.new(@panel, -1, ''Type in here'' )
    @inputSizer.add( @text1, 0, 
Wx::ALIGN_CENTER_HORIZONTAL|Wx::ALIGN_CENTER_VERTICAL|Wx::ALL, 5 )
    
    st2 = Wx::StaticText.new( @panel, -1, "Text:" )
    @inputSizer.add( st2, 0, 
Wx::ALIGN_CENTER_HORIZONTAL|Wx::ALIGN_CENTER_VERTICAL|Wx::ALL|Wx::ADJUST_MINSIZE,
5 )
    
    @text2 = Wx::TextCtrl.new(@panel, -1, ''Type in here'' )
    @inputSizer.add( @text2, 0, 
Wx::ALIGN_CENTER_HORIZONTAL|Wx::ALIGN_CENTER_VERTICAL|Wx::ALL, 5 )

    @inputSizer
    end
end

app = TestApp.new()

Since you are using a FlexGridSizer, you need to set the growable column 
and/or row. Add the following to your TestApp.on_init method, after you 
create the @topSizer.

@topSizer.add_growable_col( 0 ) #the 1st column, which houses your grid
@topSizer.add_growable_row( 1 ) #the 2nd  row, which houses your grid

WxGrid is derived from WxScrolledWindow....and there is a method 
enable_scrolling on WxScrolledWindow, but it doesn''t appear to be 
working, at least for WxGrid. I''ll check it out later this week if 
somebody doesn''t get to it first.

When it is working you should be able to say:
	@grid.enable_scrolling( false , false )
to disable both x and y scrolling

Another way that should disable the scrollbars is by giving the WxGrid 
enough screen space to be shown for it''s total width and height. The 
method "get_best_size" and "get_adjusted_best_size" should
give you the
desired/preferred size of your Wx component, but they appear to be off 
by a few pixels. You can refer to the wxWindows documentation: 
http://www.wxwidgets.org/manuals/2.4.2/wx411.htm#wxwindow for more 
information.

There are a few quirks with WxGrid. I don''t know if they are WxRuby 
related or WxWindows related (I''ve never used WxWindows outside of 
WxRuby). The WxGrid seems to want to have white space at the bottom and 
at the right of the WxGrid. This appears to be the space that the 
ScrollBars would take up, and I can''t say how to get rid of it.

Feel free to keep asking Dale, if us folk on the list know an answer 
we''ll give it to you, if we don''t we''ll try to find
it out!
