Get entry text from wxTextCtrl in C++
I have this piece of code:
void stoiximanFrame::OnButton1Click(wxCommandEvent& event)
{
cout<< TextCtrl1.GetValue() <<endl;
}
I just want to get the text from TextCtrl1 and I get this error:
stoiximanFrame::TextCtrl1’, which is of pointer type ‘wxTextCtrl*’ (maybe you meant to use ‘->’ ?)
I'm new to C++ so I've never used pointers before. I've read the basics of pointers but still I couldn't figure out how to solve the problem above.
In addition, I would appreciate any good documentation about how and when to use pointers.
Thanks.

TextCtrl1 seems to be a pointer to an object of class wxTextCtrl(also wxTextCtrl*). By using the arrow operator -> you access the public members of the object the pointer is pointing to. It is a shortcut for using dereferencation(*) and member access(.).
This means TextCtrl1->GetValue() is equivalent to (*TextCtrl1).GetValue()
So just do what your compiler says and write
cout << TextCtrl1->GetValue() << endl;
to solve your problem.
If you are new to C++ i recommend you to read about pointers. For example here because that's one of the major differences to other languages.

Wow, C++ seems so different from other programming languages. "->" is really unprecedented for me. Thanks for this useful clarification.
