Re: [Matplotlib-users] Prompt in MPL - NEVER MIND
Hello everybody, first of all I hope my mails on the issue 'Prompt/TextBox/InputButton' don't become to many. But I had one more idea and I want to share it with you. If you don't like my usage of lists as a pointer to variables, one could replace this in two steps: 1) Adding a new method 'get_text' to get the actual label text (def get_text(self): return self.label.get_text() ) 2) In the example one would include a function to set one's variable to the evaluated label-text. Than one would add this function into the self.observers and so call it after every finished typing mode. This new behaviour has the big advance that error-handling during evaluation of the text is a task for users and not to mpl. I hope I could explain my idea ... best regards, Matthias On Wednesday 27 June 2007 18:19, Matthias Michler wrote: Hello everybody, in my last version I forgot to include a very useful function (it is comparable with the 'Button.on_clicked' function).

Re: [Matplotlib-users] Prompt in MPL - NEVER MIND
Hello everybody, first of all I want to thank John for his work on the textbox - it really looks better than mine. On Tuesday 05 June 2007 19:16, Mark Bakker wrote: I just saw in the code: if event.key is None: # simulate backspace So it works properly, Mark In my opinion it would be a better soluton to generally add some more key-events (e.g. enter and backspace) than to simulate backspace with all 'None'-keys. Some time ago I posted a suggestion to that (subject: 'additional key events'), which may be got lost among the lots of mpl-mails. I just send the patch once more, because I think it would be helpful for such a prompt. best regards, Matthias On 6/5/07, Mark Bakker [EMAIL PROTECTED] wrote: I notice the alignment problem.

Re: [Matplotlib-users] Prompt in MPL - NEVER MIND
Hello John, first of all thank you very much for adding this patch. By the way: What do you think about the insert a 'l' or 'g' into your TextBox and get a grid or log-scale-issue? Is there a possibility to switch the mpl-meaning of 'l', 'g' and 'f' off? best regards, Matthias On Wednesday 06 June 2007 16:19, John Hunter wrote: On 6/6/07, Matthias Michler [EMAIL PROTECTED] wrote: Some time ago I posted a suggestion to that (subject: 'additional key events'), which may be got lost among the lots of mpl-mails.

I'd like to do a few enhancements to the text box widget and then add it to svn.
