Maximum length of text in wx.TextCtrl

[Martin Manns]

Hi,

According to the docs, the maximum text length that a wx.TextCtrl
supports depends on the platform.

1) I am looking for a method that returns this value.

2) Is there a text entry widget that supports long lines (>64k)?
My use case is giving access to code that includes serialized data.

Thanks,

Martin

That does not work here.

I have tried:

style=wx.TE_PROCESS_ENTER|wx.TE_RICH

and the line is truncated at 65534 characters.

I am working with Debian unstable:
wxPython 2.8.12.1
(wxGTK, unicode, gtk2, wx-assertions-off, SWIG-1.3.29)
Running on Python 2.7.3rc2

Regards

Sorry, I thought you meant total text length. There probably isn't
anything that can be done to make the native text widgets allow larger
line lengths. If all you need is the ability to display the text then
you can easily create a custom widget that allows longer lines, although
you may still run into issues with a limited range supported by the
scrollbars. On the other hand, I know I personally hate reading text
with lines longer than about 200 characters, so you might want to think
about some other way to display the data that will make your users happier.

Thank you for pointing out the bad usability.

I am using the Textctrl as an Editor in a wx.Grid. When cell editing is
started, the wx.TextCtrl automatically truncates the text. Therefore, I
would have to pre- and postprocess the code before and after editing.

I would prefer a widget that can be used as editor for arbitrary
cell content lengths in a wx.Grid. Better usability than a TextCtrl
of course would be nice.

Do you have an idea what to use?
