Challenge: custom textctrl

wxPython Users
1

Can a custom textctrl be created such that each group of text (each line in a file) could have an associated custom widget?

note: Initially I tried to implement such that, for each group of text, a new custom widget with textctrl was added to a stack with that line, but became slow (apparently) because of memory usage.

How might it be possible to do any of the following? If possible, which one, if any, would be most practical to implement?

1. Identify a block of text (with a border, for instance) when cursor is in that text, along with its associated data/widgets on a side panel

2. Display custom widgets on textctrl (in between or associated with lines)

Thanks

Sounds more like a ListCtrl to me.

Download the wxPython demo and have a look at e.g.:
- HyperTreeList
- UltimateListCtrl

Or maybe I don't understand what you are looking for.

Thanks for the direction.

I ended up finding UltimateListTextCtrl, although unable to initiate it, receiving the error: “Exception: invalid item index in GetItem”

**note: **

I just installed Python 2.6.1 as needed for the wxPython Demo

In the attached file, I also tried initiating the UltimateListTextCtrl with an empty list item

test – UltimateListTextCtrl.py (2.47 KB)

I never used it myself, but with the following changes it runs and
displays.
Change line 18 to:
self.ultimateList = ULC.UltimateListCtrl(self, agwStyle =
wx.LC_REPORT And comment line 29 - this is creating a second list
At this point I see a list with two rows and columns.

After changing line 18 as directed, I had to comment out line 29 (the UltimateListTextCtrl) for this to run, displaying via the UltimateListCtrl. The ULC was only created to pass into the UltimateListTextCtrl to instantiate it. The error still occurs.

Sorry for the delayed response.
