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

Need some assistance with animation again... When I run the drawing code in a separate thread, it''s slow as heck. I think it may be because the drawing thread isn''t getting enough time from the thread scheduler. I was able to reproduce the problem in my little sample program simply by increasing the number of lines it draws per update. I''m lucky to get one frame

Hi wxRuby Gurus, I''m trying to write a sample program which allows me to drag an image (by left_mouse_button down) across the canvas. I got it to work ... well, sort of. The problem is I can drag it only by clicking on the left top corner of the image and nowhere else. Besides, the dragging is not very smooth. How can I make it better? I am using wxRuby 0.6.0 on Win XP (Home) and

Hi, I''m running into something along the lines of bug 5383. I''m hoping I''m doing something obviously wrong and that someone can point me in the right direction. I''ve got a custom paint event handler: def on_paint puts "mainframe on_paint" paint do |dc| dc.clear @cl.draw dc end end Then I''ve got a key press

OK, I have a basic blit demo working (thanks to Alex Fenton for his reply, which I finally saw). However, there''s a great deal of "tearing" on the screen - flickering grey lines in the black background. It looks like the blit isn''t always complete when the screen refreshes. Can anyone look at this and tell me what I might be doing wrong? Any help would be most

OK, back with another iteration of the same problem... I updated my game demo, but the Close button failed to respond when (and only when) there were too many objects onscreen. The drawing loop is probably lasting longer than my drawing timer interval. I was able to reproduce the problem in my (probably familiar by now) test script just by boosting the number of lines drawn per frame. After

Hi, I''m working with wxruby since 2 days but next to this Wiki: http://wxruby.rubyforge.org/wiki/wiki.pl and this Doc: http://wxruby.rubyforge.org/doc/ I couldn''t find something usefull for it. Also del.icio.us has no intresting links. Do you know any good website or book about wxruby? My problem at the moment is, I wanna test the TaskBarIcon on Gnome and so I did:

Hi, 1) Can the online api docs get updated? Specifically can the overview pages get added in to the main http://wxruby.rubyforge.org/doc/ index.html page? I happened upon the link to the Event Overview page while browsing some class and wished that it had been listed in the Event section of the index page.I don''t know how many other "overview" pages there are but it

dear railers I was attempting to display a svg chart inside a tooltip in rails using Scruffy. my browser is Firefox 2 and i am using WEBRICK. when i render inside the controller using graph.render(:size=> [255,205], :to => ''C:\xyz.svg) and serve iit via rhtml using the <embed> tag. Instead of the chart inside the tooltip i get a dialog box asking me to open it ... with

Attached is a patch and some extra files to fix our ObjectPreviouslyDeleted crasher with the paint method. As discussed, it just re-implements the method in Ruby. I created a directory lib/wx/classes as a place to hold Ruby extensions to the API. The attached app.rb and window.rb files should be added to it. When this patch is applied, files in that directory are automatically required on

Hey there. I have an application that I developed with an older branch of wxruby some time ago, and I made heavy use of the LayoutConstraints class. I''ve been looking around, but so far haven''t found much in the way of advice for this scenario. Is there any existing documentation as to updating such applications? Thanks, Ess -- SO not teh 1337

Hi everybody, I''m using scruffy to create some graphs, and would like to integrate them into a regular view (i.e. show them in an <img> tag). However, I get errors when using img_tag, or the image doesn''t load if I try saving the graph to disk and then loading them in html. Generating the graph and linking to it works, however then I only have the graph open in a new

Hi all Have been taking a look at the samples to see what''s broken. Not looking TOO bad overall, but a few problems we should try and tackle before alpha: Firstly, I have a few commits (minimal, dialogs, unicode) - anyone else been working on these or can I go ahead? One general issue is that many of the samples rely on being run from their own directory, but don''t enforce

Sorry if this is a repost for those of you who are also on the wxusers list. But I thought I might get some more specific feedback here. I am interested in producing graphical interface elements, like those: http://azureus.sourceforge.net/img/sc/2.1.0.2/statistics.png and http://azureus.sourceforge.net/img/sc/2.1.0.2/torrent_general.png Can anyone point me to what wxruby widgets might work to

Hi- Trying to do a stacked bar chart, but nothing is rendering when I add more then 1 bar: This works: graph = Scruffy::Graph.new(:title => "My Chart") graph.add :stacked do |stack| stack.add(:bar, ''Stack1'', [10,10]) end This doesn''t: graph = Scruffy::Graph.new(:title => "My Chart") graph.add :stacked

I''m trying to put together a quick test of buffered animation with WxRuby, but I''m encountering a fair amount of trouble... I''m drawing to a Wx::Bitmap first, then using Wx::DC#draw_bitmap to copy it to a Wx::Window. But I get the following error: C:/ruby/lib/ruby/gems/1.8/gems/wxruby-1.9.1-i386-mswin32/lib/wx/classes/bitmap.rb:18:in `draw'': uninitialized

Hiya, I was trying to figure out how to display PNG files using wxWindows/wxRuby. Google turned up a few things, mainly discussing the wxImageHandler class and it''s children, etc, but there seems to be no mention of them in the wxRuby source. Are they there, and I missed them, or are they just not there? If there not there, is there a quick and dirty way to get them in? It seems like
