@generalloki, thanks for all new "functions" available for TextBox and Sample added into Text Input

So we added simple RichEdit inside of TextBox. We still need to add some TextBoxPanel with speed buttons in order to test RichEdit functionality properly. Something like this:

May be we need to create a separate control like RichTextBox (and just set IsRichEdit = true in the constructor)?

This is good idea. But first we need to study difference between wxRichTextCtrl (https://docs.wxwidgets.org/3.2/classwx_rich_text_ctrl.html) and wxTextCtrl in rich edit mode. Also we need to study whether wxRichTextCtrl/wxTextCtrl has file save/open feature in rich text format.

[dmitry-medvedev]

sounds good, wxRichTextCtrl may provide extra features, need to be investigated.

I am closing this issue for now as fully featured RichTextBox is implemented
