Hi, I'm trying to learn wxRuby. This is program: require 'wx' include Wx class MyFrame < Frame def initialize super(nil,-1,"Mi primera ventana Wx!") @panel = Panel.new(self) @lbl1 = StaticText.new(@panel,-1,"Label") @text1 = TextCtrl.new(@panel,-1,"Text Value") @combo =ComboBox.new(@panel,-1,"Combo Text") @button

Hi Given the warm response to the syntax additions in 1.9.1 I''m considering moving one or two more syntax extensions into core, and would like your thoughts. Last ones, I promise. Realise we don''t want much more API change now, but also we''ll probably also have to live with whatever we settle on for 2.0 for a little while, so... 1) Setting up event handlers In

I am testing out the grid-plots, but get into a problem making a legend. I have a line plot and some points, following the model in grid.plot.and.legend() i manage to get the points correctly in the legend, but what do I do with the line? (Of cource, I can just draw a line at the right location on the plot, but I would prefer to use legend) Morten -- Morten Sickel Norwegian Radiation

Hi I''d like to put out a 1.9.3 release perhaps later this week/weekend. If you have a chance to test the build and samples esp with latest rubygems, please do. There are still some bugs on the list, and samples to do, but this should address all the build/install probs that have come up. And it would be good to get some testing and feedback on some of the new classes. A note on the

Hi, Thanks to the newly added event handlers for Wx::Grid in the 0.6.0 release, I can now provide a much slicker intreface to my "data widgets" which heavily rely on that control. However, I haven''t quite figured out how to programmatically scroll to the last row of a populated grid (actually, the first empty row). So say that I have a grid with 200 rows only 20 of which

Hi Do a search on ''wxruby'' and you''ll see that people''s main gripes are 1) stability 2) development progress 3) documentation and 4) syntax. We''re making great progress on 1-3 so thought it seemed like a good time to start looking at 4). So here''s announcing a first release of WxSugar. It can be downloaded via gems (gem install wx_sugar)

Really stupid question, but have you wrapped this all in an App class? If you don''t have a wxApp subclass driving your applications then all sorts of badness would happen. > I''m writing a custom little application for my boss''s high school > football team to track there stats play by play. > > My problem is that when I start the application, it

Hi all, I''ve got a question concerning ListCtrl_virtual of wxRuby since I see no way filling the list with dynamic contents. I''m new to Ruby so I maybe have to apologise for my request. The problem is, that I have to define the on_get_item_text(item, col) function. There I would like to use the item and col variables to read data from a two-dimensional array. My very problem

I have installed Simple Sudoku (http://www.angusj.com/sudoku/index.php) but I cannot minimise it, nor go to another screen to do something else. If I try, its window gets larger, vertically. I am using wine 20050725 (which is what is packaged for my system at present), on a Debian system running XFree86, with icewm-gnome. Can anyone advise why this program "hogs attention"? -- Phil

I''m trying to do some advanced editing using Grids. I''ve created my own editors and updating view and model both works fine so far. Thanks to whoever made this possible. I like wxRuby more each day! Now I''d like to catch mousewheel events in order to increment/decrement a grid cell editor. I''ve tried installing a handler in begin_edit of my editor and removing

Hey Kevin, Am I correct in assuming that if I want a particular widget to respond to an event which doesn''t take an ID as an argument (like evt_size or evt_left_down), that I have to inherit a new widget and define the event handler within the inherited class? Here''s a little contrived code example to illustrate what I mean: class MyCtrl < Wx::TextCtrl def

Hi, Are there any effort in making wxDocument, wxView, etc types of classes avaiable under wxRuby? For supporting SDI/MDI architecture. Cheers, Phuah Yee Keat

I'm having trouble with something that looks easy. (And I'm sure it will be easier within about 1 minute of receiving my first response.) Thanks in advance. I have a collection of data frames that I need to add columns, do some calculations and then fill in the new columns. Since I have a large number of similar data frames I want to do this with functions to make the code more readable

Hi, I have a data.frame that is date ordered by row number - earliest date first and most current last. I want to create a couple of new columns that show the max and min values from other columns *so far* - not for the whole data.frame. It seems this sort of question is really coming from my lack of understanding about how R intends me to limit myself to portions of a data.frame. I get the

Hi, I need to keep a running count of events that have happened in my data.frame. I found a document called usingR that had an example of doing this for random coin flips and I tried to modify it. It seems to sort of work in the beginning, but then it stops and I don't understand why. I'm trying to duplicate essentially the Excel capability of =SUM($A$1:$A(Row number)) The example

I have a data frame somewhat like this: myframe <- data.frame (ID=c(2,3,4,5), Hunger =c(415,452,550,318 )) myframe Now I would like to add a column to the right which summarizes the values for Hunger somewhat to reduce the number of values: If the values for Hunger are between 300-400 I would like to insert the number 350, between 400-500 insert 450 between 500-600 insert 550 Does

Hey guys, It''s been awhile, but I''ve put up a new tutorial page on Wx::Frame. It''s the first half of the tutorial on Frame, the rest will come a little later. Let me know what you guys think. Any comments or criticisms are welcome. Let me know what was good and what could have been better, so that future tutorials will be able to incorporate those improvements.

Any doubts about R's big-league status should be put to rest, now that we have a Sudoku Puzzle Solver. Take that, SAS! See package "sudoku" on CRAN.
