27.3 Adding a Text Control to the Frame

• Again, we use inheritance to define our own, more interesting, type of frame.
• This frame contains a text area into which users can type any text.

  class TextFrame : public wxFrame
  {
  public:
     TextFrame();
  private:
     wxTextCtrl* text;
  };

• The constructor initializes the base class and the text control:

  TextFrame::TextFrame()
     : wxFrame(NULL, -1, "TextFrame")
  {
     text = new wxTextCtrl(this, -1, "Type some text here!",
        wxDefaultPosition, wxDefaultSize, wxTE_MULTILINE);
  }

• Note that first parameter (this) indicates that the parent of the text control is this frame.
• The next two parameters indicate a default window ID and initial contents of the text control.
• The next two parameters indicate default size and position.
• The final parameter turns on the "multiline" style, which allows the text control to hold multiple lines of text.
