[wxruby-users] Detaching Controls

[Mario Steele]

Another way, if your planning to re-use the control, is to call
hide()/show(false) on the button, then call layout() on the window, to
re-draw the controls.  Hide will make it invisible, so that it's no longer
there.

An example:

begin
    require 'rubygems'
rescue LoadError
end
require 'wx'

class MyFrame < Wx::Frame
    include Wx
    def initialize(*args)
        super
        @button1 = Button.new(self,1000,"Hide Me!")
        @button2 = Button.new(self,1001,"Show other button")
        hbox = BoxSizer.new(HORIZONTAL)
        hbox.add(@button1,1,ALL)
        hbox.add(@button2,1,ALL)
        set_sizer(hbox)
        evt_button(1000) do
            @button1.show(false)
            layout()
        end
        evt_button(1001) do
            @button1.show(true)
            layout()
        end
    end
end

Wx::App.run do
    MyFrame.new(nil,:title=>"Button Hiding Example",:size=>[200,60]).show()
end

L8ers,
