wxRichTextCtrl, some questions

[spectrum]

hi all,
i am using wxRichTextCtrl on linux, wxGTK wxWidgets 2.9.2 for developing a serial comm terminal,
below some questions,

1. is the caret customizable ? I would like it to be a rectangle, i already tried with GetCaret / SetCaret, SetSize etc, nothing works.
2. is there a way to allow the user to delete "only" the characters written by him (no the WriteText written chars) ?
3. is there sme other more appropriate wxWidgets control for this ?

many thanks

Regards,
angelo

1. No idea : it should be, but I never tried it
2. No : once the text has been inserted, the control does not remember if it was introduced from a keystroke or from a WriteText method. So, you will have to handle this functionality yourself.
3. I think yes. I am not sure you need rich text functionality for terminal emulation. Maybe a wxTextCtrl would do the trick ?

thanks for the replies.

- I need to handle some vt100 special codes, so to be able to change colors on the fly. wxTextCtrl is not able to do this.
- I am wondering what controls are using putty or gtkterm, since they allows colors and a rectangular cursor.

For a terminal wxStyledTextCtrl may be more appropriate (it has features like code folding and syntax highlighting but you don't need to use them). I'm think the caret is customizable in it. A custom lexer might be able to handle vt100 colors too

i have found that gtkterm use "libvte-dev", and probably putty too.

Would be nice to find some c++ wrapper, or better, a wxWidgets similar equivalent.

Well, under Windows, you can handle colors with a wxTextCtrl. Take a look at wxTextCtrl::SetStyle method. I never tried this under Linux, but you can give it a try. Note that for this purpose, syntax highlightning capabilities of wxStyledTextCtrl will not be helpful as they are based on predefined syntax rules, and not information received from VT100 commands.
