wxTextCtrl Selected Text

Hi. How do you make it so text stays selected when the contents of a text control change? Every time the contents change, my selection gets unselected...

i would try to reselect all, inside the "change" event.

Ok, I traced it to this function:
Code: Select all
void wxRichTextCtrl::DoWriteText(const wxString& value, int flags)
wxString valueUnix = wxTextFile::Translate(value, wxTextFileType_Unix);
GetBuffer().InsertTextWithUndo(m_caretPosition+1, valueUnix, this, wxRICHTEXT_INSERT_WITH_PREVIOUS_PARAGRAPH_STYLE);
if ( flags & SetValue_SendEvent )
Since AppendText doesn't use the flags, it can only be that InsertTextWithUndo line.
Any ideas how to stop it from deselecting selected text?

That the selection gets lots when changing/adding text is pretty much standard behavior in any textcontrol in know of. I guess your only chance is to store/restore the selection yourself after adding text, but you might get an ugly flicker.

Yeah, that's what I did. Works out ok. Thanks.
