How to make \n appear in wxTextCtrl? Topic is solved

[Tapsa]

I have constructed wxTextCtrls using:

Code: Select all

wxTextCtrl(parent, wxID_ANY, "", wxDefaultPosition, dimensions, wxTE_MULTILINE)

\n in the strings is neither converted to actual new line nor displayed in any way. It is completely omitted in the wxTextCtrl. How can I make it appear as \n or as new line?

I'm using 2.8.12.

It works in wx version 3.0.2. You might try to "\r\n" instead since that is the default line break sequence in windows.

They are strings loaded from DLL. I would rather have them shown as they are.

What exactly does the string contain, the real newline code (0x0a) or the characters "\" and "n"?

Using hex viewer I can see "42 00 6C 00 6F 00 63 00 6B 00 0A 00 50 00 72 00 69 00 6E 00 74 00 69 00 6E 00 67 00" so yes it has 0A aka new line.

That makes sense, because i don't think the text control itself converts "\n" to 0x0a.

If you want to display 0x0a as "\n", you'll have to replace it in the string. I don't think you can tell the text control to display it differently.

Does a replace do any change?

Code: Select all

wxString str = (set to whatever);
str.Replace("\n", "\r\n");
text_ctrl->AppendText(str);

Thank you. I had lots to do so took a while before testing this.
Apparently Resource Hacker and Resource Tuner both replace 0x0A with \n.

\n is just a C-style escape character for 0x0A and equals to \x0a, \r\n equals to \x13\x0a
