Hi, any ideas whether you can set the background of a dialog to use an image?

The example below just fills with colour, but you could replace the call to gradient_fill_linear with one to DC#draw_bitmap or whatever other drawing/painting code yoou wanted. Please, just don't do anything as eyesore as this ... alex __ require 'wx' class BackgroundDialog < Wx::Dialog def initialize(parent) super(parent, :title => "dialog with background") Wx::TextCtrl.new(self, :value => 'foo', :pos => [ 50, 50 ]) evt_erase_background :on_erase_background end def on_erase_background(evt) # Use the event's DC object to draw whatever background you want evt.dc.gradient_fill_linear( client_rect, Wx::RED, Wx::BLACK, Wx::NORTH ) end end Wx::App.run do frame = Wx::Frame.new(nil, :title => 'frame') frame.show BackgroundDialog.new(frame).show end
Thanks again Alex, will give that a go tomorrow and see how things turn out. Appreciate this
I have a WxRuby app running on Windows and I want to try to port it to the new Ruby 1.9.1. I see wxruby-ruby19-1.9.8 gems for Darwin and Linux, but not for Windows. Is wxruby-ruby19-1.9.8 available for Windows yet? If not, when will it be available? And how stable is it? Thanks, Eric Rubin

Whether we offer both mingw and mswin32 for Ruby 1.9.1 is not yet finalised, but in practice they're interchangeable. There will certainly be mingw as that's the direction the OCI is going in (for good reasons, IMHO). > And how stable is it? Very. wxRuby has supported ruby 1.9 for a year now, and I switched over mainline dev of my app to it a few months ago. There are also a lot of changes in SVN HEAD which make it considerably more stable generally than the current beta releaes, 1.9.9. alex
Thanks Alex, I got the dialog to use a background image eventually, did this with WxRuby 1.9.9 on Windows XP and it works (doesn't on OSX, but don't need it to). def initialize(title) ...... evt_erase_background :on_erase_background end def on_erase_background(evt) b_splash_bmp = Wx::Bitmap.new('images/background.gif', BITMAP_TYPE_GIF) evt.dc.draw_bitmap(b_splash_bmp, 0, 0, false) end
