Take the 2-minute tour ×  I'm just learning about gtkmm for c++.
I'm having trouble getting a simple TextBuffer to add a new line
of text. I have a class called OutputBox which is an HBox with a
TextViewer (called messages) and a TextBuffer (called
textBuffer) in it.  Here is a small chunck of the OutputBox
class:  OutputBox::OutputBox() {   textBuffer =
messages.get_buffer();  void OutputBox::addText( string newText)
{   textBuffer->insert(textBuffer->begin(), newText);  Now I
expect that when I pass a string into addText, the new string
will be added to the buffer, but instead I get a seg fault.
After running it through gdb, I see that the error comes from
the gtkmm libraries here:  template <class T_CppObject> inline
T_CppObject* RefPtr<T_CppObject>::operator->() const   return
pCppObject_;  I'm not really sure what this is telling me
either. I assume that I'm incorrectly using the class.
