Greetings,

I am just started to use wxruby to create GUI for my project. i need to  
draw a state diagram based on some summary file. May i know is there any  
way in wxruby that allow people to draw circle and add text on it?

Thanks a lot.

Yes, there is. Have a look at the documentation for “device contexts”

[http://wxruby.rubyforge.org/doc/#device\_contexts](http://wxruby.rubyforge.org/doc/#device_contexts)

And also the samples in the samples/drawing

Hi Alex,

thanks for the useful information provided. 🙂  
I am expecting the code will generate the drawing automatically based on  
the information in a text file.  
Will continue to work on it. Hope it won’t be hard…
