...ch now includes a GraphicsContext demo, just in time for a release. *wipes forehead* So far, it''s looking pretty good. BTW Alex, another bug came up while working with GraphicsContext, but wasn''t something as major that could prevent me from completing the demo. GraphicsContext#draw_lines(size_t n, Point2Double points, Integer fillStyle) Need another typemap wrapper for Point2Double. And I''m thinking that it should be an 2d array of sorts. Points represented by [x,y], and array of them, EG: [ [first_x,first_y], [second_x,second_y], [third_x,third_y], ....etc......

I use dc = DC.new() dc.draw_line(50, 50, 100, 100) but it can''t be compiled I don''t know how to declare DC variable?? in http://wxruby.rubyforge.org/doc/dc.html it don''t tell me how to declare now variable plese tell me :''( -- Posted via http://www.ruby-forum.com/.

Anyone know how to draw in wxRuby? I want to draw a graph, and have it update as new data comes in. I see stuff about Device Contexts, but I can''t find anything about how to use them, associate them with a panel, or anything like that. -Kurt

Hello, I would like to get a window handle from another app outside of wxRuby and convert it into a wxRuby Window handle so that I can use it as the parent Window for several wxRuby child windows. Basically I want to use the FRAME_FLOAT_ON_PARENT window style so that my wxRuby windows become associated with the outside app kind of like toolbars, e.g., they don''t show up in the
