[wxruby-users] Problem centering a label

Hi Alejandro,

you just need one sizer on your panel. Add one spacer 
(sizer.add_stretch_spacer) before and one after your text.

Like so:

    sizer = BoxSizer.new HORIZONTAL
    sizer.add_stretch_spacer
    sizer.add StaticText.new(self, -1, ''asdf''), 0, 1
    sizer.add_stretch_spacer

hth,
Christian.

[wxruby-users] RES: Problem centering a label

Christian :

 

I say in the other mail ?I have a frame?,  brong  i have a panel.

 

The panel is inside the main frame.

 

I change my code to :

 

class TarefasNova < Wx::Panel

    def initialize(parent)

        rect = parent.get_client_rect();

 

        super( parent, 1011, Wx::Point.new( 0, 0 ), rect.get_size(),

              SIMPLE_BORDER,

              "NovaTarefa" );

 

        #sizer = Wx::BoxSizer.new(Wx::VERTICAL)

 

        box   = Wx::BoxSizer.new(Wx::HORIZONTAL);

 

        box.add_stretch_spacer();

 

        box.add Wx::StaticText.new(self, -1, ''asdf''), 0, 1

 

        #label = Wx::StaticText.new( self, :label => "CADASTRO DE
TAREFAS
(NOVA)", :size => [250,-1] );

 

        #box.add( label, 1, Wx::ALIGN_CENTER, 5);

 

        box.add_stretch_spacer();

 

        #sizer.add_item(box, 0, Wx::ALIGN_CENTER|Wx::ALL, 5);

    end

end

 

But the text is not centered, the text is in the left.

 

Exist some diferences between frame and panel to user sizer?

[wxruby-users] RES: Problem centering a label

Hi Alejandro,

I''m not sure to understand why you need 2 sizers but your main problem
is that you haven''t told the panel to use the sizer !

Here is a sample code where there are 3 texts :
- at the top, the text is centered
- at the middle, the text is left aligned
- at the bottom, the text is right aligned

The important line is the one with self.sizer = box.
You should also use wx constants to make your code clearer.

#!/usr/bin/env ruby
# wxRuby2 Sample Code. Copyright (c) 2004-2008 wxRuby development team
# Freely reusable code: see SAMPLES-LICENSE.TXT for details
begin
  require ''rubygems''
rescue LoadError
end
require ''wx''

class MyPanel < Wx::Panel
  def initialize(parent)
    super(parent)
    box = Wx::BoxSizer.new (Wx::VERTICAL)
    box.add_item(Wx::StaticText.new(self, :label => "Centered
Title"),
:flag => Wx::ALIGN_CENTER)
    box.add_item(Wx::StaticText.new(self, :label => "Leftside
Text"),
:flag => Wx::ALIGN_LEFT)
    box.add_item(Wx::StaticText.new(self, :label => "Rightside
Text"),
 :flag => Wx::ALIGN_RIGHT)
    self.sizer = box
  end
end

# This is the minimum code to start a WxRuby app - create a Frame, and
# show it.
Wx::App.run do
  frame = Wx::Frame.new(nil, :title => "Minimal wxRuby App")
  panel = MyPanel.new(frame)
  frame.show
end

Cheers.

Chauk-Mean.

[wxruby-users] RES: Problem centering a label

Hi Alejandro,

this one actually works:

class TarefasNova < Wx::Panel
    def initialize(parent)
      super( parent, 1011, {:style => SIMPLE_BORDER, :name 
=>"NovaTarefa"} );

      box = Wx::BoxSizer.new(Wx::HORIZONTAL);
      box.add_stretch_spacer();
      box.add Wx::StaticText.new(self, -1, ''asdf''), 0, 1
      box.add_stretch_spacer();

      set_sizer box
    end
end

Watch for the parents'' constructor - you needn''t set size and
position.
Also never forget to call Panel#set_sizer or your sizer won''t have any 
effect.

hth,
Christian.

Simpler, using StaticText ALIGN styles instead of extra spacers

box = Wx::VBoxSizer.new
st = Wx::StaticText.new(self, :label => ''adsf'', :style
=> Wx::ALIGN_CENTRE)
box.add st, 0, Wx::GROW

This is a good point - use sizers to have children adjust to their 
parent''s size. Also, if a window is the only child of a frame parent 
(often the case with Panels inside Frames) then it will automatically 
take up all the avaiable space - no sizer needed.

[wxruby-users] RES: RES: Problem centering a label

Chauk-Mean. :

Your  code runs ok in a separate file.

 

If i call MyPanel from my menu to put the panel in my main frame, the code
does not work.

 

This code :

 

begin

  require ''rubygems''

rescue LoadError

end

 

require ''wx'';

 

class TarefasNova < Wx::Panel

  def initialize(parent)

    super(parent)

    box = Wx::BoxSizer.new (Wx::VERTICAL)

    box.add_item(Wx::StaticText.new(self, :label => "Centered
Title"),

:flag => Wx::ALIGN_CENTER)

    box.add_item(Wx::StaticText.new(self, :label => "Leftside
Text"),

:flag => Wx::ALIGN_LEFT)

    box.add_item(Wx::StaticText.new(self, :label => "Rightside
Text"),

 :flag => Wx::ALIGN_RIGHT)

    self.sizer = box

  end

end

 

The panel only shows ?Righ?.

 

Does not size to fill frame.

 

When i put :

 

        rect = parent.get_client_rect();

 

        super( parent, 1011, Wx::Point.new( 0, 0 ), rect.get_size(),
SIMPLE_BORDER, "NovaTarefa" );

 

This makes the panel fill frame.

 

The frame has menu bar and statusbar.

[wxruby-users] RES: Problem centering a label SOLVED!!!!

Hi :

 

The problem is that, after call to create the child panel, i need to call
send_size_event().

 

I find the solution becouse i minize the aplication to see the code in the
editor and when i maxsimize the aplicattion the panel is ok filling all the
frame space.

 

Alejandro
