wxchoice inheritance Topic is solved

[guzzi_jones]

I would like to create a new class called mychoice that inherits wxChoice. I would then like to load the choice using the constructor. Is ths a bad idea? i will be using this wxChoice other places in the program and I don't want to rewrite the code to load it for each form. Is this a good idea? I am missing something, but I don't know what. thanks again.

here is what i have so far pulled from the tutorial:
code:

#include "wx/wx.h"
// a choice which handles focus set/kill (for testing)
class mychoice : public wxChoice
{
public:
mychoice(wxWindow *parent,
wxWindowID id,
const wxPoint& pos = wxDefaultPosition,
const wxSize& size = wxDefaultSize,
int n = 0, const wxString choices[] = NULL,
long style = 0,
const wxValidator& validator = wxDefaultValidator,
const wxString& name = wxChoiceNameStr )
: wxChoice(parent, id, pos, size, n, choices,
style, validator, name) { }

protected:
void OnFocusGot(wxFocusEvent& event)
{
wxLogMessage(_T("MyChoice::OnFocusGot"));

event.Skip();
}

void OnFocusLost(wxFocusEvent& event)
{
wxLogMessage(_T("MyChoice::OnFocusLost"));

event.Skip();
}

private:
DECLARE_EVENT_TABLE()
};




g++ mychoice.h `wx-config --cppflags --libs`

i put my 3 files in pastebin at http://pastebin.com/HuXLAwRi

now i get the error "undefined reference to "vtable for mychoice.""

any help appreciated.

If you have a DECLARE_EVENT_TABLE() in your class declaration, you also need a matching BEGIN_EVENT_TABLE()/END_EVENT_TABLE() in your implementation file.

If you don't need a static event table, just comment out the DECLARE_EVENT_TABLE().

thanks for the tip.
Now i am back at my original debug info above. If anyone has a sample of inheriting wxchoice using a header file and implementation file i would appreciate that.
as always thanks

ok i just needed to add my code to a project with a main() call. thanks it works!
