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

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

I see that this problem was noted a while ago (http://rubyforge.org/ tracker/index.php?func=detail&aid=251&group_id=35&atid=218) but it seems not to have received much attention. Any chance that it will be looked at anytime soon? So far, I prefer wxRuby to Ruby/Tk because of that closer coupling with the native window manager. However, the memory leak is just murdering me.

These enable DrawLines and DrawPolygons. I disable the wxList one since the WX docs indicate that the list is now ''type-safe'' requiring a derived class to send a wxList of Points. Since we''re unlikely to do this I just blocked it off so it doesn''t interfere with internal functions that may call that one. Note: MemoryDC doesn''t inherit from DC.h.

How can I use the drawing canvas and its off-screen image buffer, say FXImage, to dynamically resize or have its width and height attributes changed in reply to user interaction with the main window (FXMainWindow)? It seems that whem I put initial values to W and H of the canvas or FXImage, they remain with its initial values no matter what I do whem resizing the main window. -- Ranieri Barros

[third sending attempt...] I''m going to try and test out the samples on MSW over the next few days and if things look good I think we should release 1.9.2. Might try and fix the bugs related to TreeCtrl#get_first_child as these might involve minor API changes. So if anyone has any time to test out SVN HEAD and look for anything funny, please do. Also, we have an anonymous patch

Congratulations, wxRuby2 0.0.40 but,where is 0.0.40 mswin32.gem? _______________________________________________ wxruby-users mailing list wxruby-users@rubyforge.org http://rubyforge.org/mailman/listinfo/wxruby-users

I''ve tagged 0.0.40 in subversion and created the release on rubyforge. Roy, Sean, please could you compile and upload the binary gems when you have a moment - thanks in advance. Drop me a line off list so I know when to make an announcement. cheers alex

I generate a lot of URL''s in my Facebook related code that point to our main site, not our FB app. My understanding was that the way to do this was to use ":canvas => false" as a parameter to url_for and link_to and so on. However, that doesn''t seem to generate the proper URL''s. The URL''s still point to apps.facebook.com (because they

Hi all, Just looking for a quick sanity check. I was thinking of writing a plugin for rails to give rails developers a good way of using the new firefox 1.5/safari canvas tags. I was thinking of grabbing an existing ruby graphics library and modifying it so that it renders via the canvas tag.. So you could have link_to_remote pointing to controller actions that instead of returning

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

Hi guys, I am new to this list and thought i''d say hello. I am using facebooker on a new project and so far I am really pleased with it. I saw that some users are having woes with the url_rewriter breaking urls for paths outside of the facebook canvas (i.e. your site supports both facebook and non-facebook users). I don''t have a prefect answer for this but I wrote a

I would like to use R.oo and tcltk to implement a Turtle World. I have encountered many problems because: 1) I am not sure how to implement static fields with R.oo 2) I am not sure how to implement a constructor that would call a function only for the first instance of a class (i.e., to initialize value of static fields only once) 3) I am not sure how to remove/delete cleanly existing

I found a reference to using attachment_fu and followed the lead of it but having an issue with the redirect_to that renders the fb:render tag - In my form I''m setting the canvas to false, file is being uploaded / save fine but when I attempt to redirect: redirect_to :action => :new, :canvas => true Unfortunatly it looks like my callback URL is getting printed twice, e.g.

The URLs for CSS/JS files are being rewritten to the address specified in the tunnel even when outside of the facebook canvas. Is anyone else having this problem?

Hi, I am having trouble debugging this one. The code is attached below, but it seems to be a problem at the C-tk interface. If I run this 1 time there are no problems if I run it more than once I start to get warnings that increase in multiples of 11 everytime I run it. Here is a sample session > source("clrramp2.r") Loading required package: tcltk Loading Tcl/Tk interface ... done

Dear all; I would like to draw a graph with vertices and edges, and I guess tcl/tk would be appropriate. I don't know tcl/tk but have googled for a 10-page (or so) introduction to 'getting started with tcl/tk in R' but without any luck. - Does anyone know of the existence of such a document or any other web-based material on the subject? - Does anyone have an (informative) piece of

I''m working on an app, and am new to both ruby and facebooker. Here is my current area of confusion: What should happen on a user''s initial visit to my app? When I hit apps.facebook.com/<my app> for the first time with no cookies or sessions or anything, I''m asked if I want to log into the app, etc., and am then redirected to my callback url outside of facebook.

So I have an existing app & facebook app in same rails application, for now I have decided to go the route of creating a controller for facebook stuff (called FaceController). (setup is canvas, fbml) So I have: facebook config http://myurl:myport/face/ My controllers name is face, so I dont even need a manual route, for the landing page it works like a charm. but, when I try to make
