Inherited Class Constructor Denial

Hi. I am trying to define a class that is inherited from another class.

//toolbar.h

#ifndef TOOLBAR_H
#define TOOLBAR_H

#include "main.h"

class ToolBar : public wxAuiToolBar
{
  public:
    ToolBar();
    ~ToolBar();
};


#endif

//toolbar.cpp

#include "toolbar.h"

ToolBar::ToolBar()
{

}

ToolBar::~ToolBar()
{

}


I hit compile, and it comes up with this error:

1
2
 
toolbar.cpp||In constructor 'ToolBar::ToolBar()':|
toolbar.cpp|5|error: no matching function for call to 'wxAuiToolBar::wxAuiToolBar()'|


So my question is why does this error occur? Can't my class have its own constructor? This is the definition of wxAuiToolBar:

//auibar.h

class WXDLLIMPEXP_AUI wxAuiToolBar : public wxControl
{
public:

    wxAuiToolBar(wxWindow* parent,
                 wxWindowID id = -1,
                 const wxPoint& position = wxDefaultPosition,
                 const wxSize& size = wxDefaultSize,
                 long style = wxAUI_TB_DEFAULT_STYLE);
    ~wxAuiToolBar();

    //...
};


If I make ToolBar have the same constructor parameters as wxAuiToolBar's constructor parameters, I get the same error. Does anybody know what I can do to fix this? Thanks for any help.

wxAuiToolBar has no default constructor as you can see. It has to be created using:
1
2
3
4
5
 
    wxAuiToolBar(wxWindow* parent,
                 wxWindowID id = -1,
                 const wxPoint& position = wxDefaultPosition,
                 const wxSize& size = wxDefaultSize,
                 long style = wxAUI_TB_DEFAULT_STYLE);

As you can see, you need to create it with at least wxWindow* parent parameter (as the other parameters have default values).

This means that in your:
1
2
3
4
 
ToolBar::ToolBar()
{

}

You will have to explicitly call the wxAuiToolBar constructor:
1
2
3
4
 
ToolBar::ToolBar() :  wxAuiToolBar(parent)
{

}


But how are you going to get a wxWindow* to pass on to the wxAuiToolBar base class??
You will have to change your Toolbar constructor to one which takes at least a wxWindow*
parameter.
Like this:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
 
//toolbar.h

#ifndef TOOLBAR_H
#define TOOLBAR_H

#include "main.h"

class ToolBar : public wxAuiToolBar
{
  public:
    ToolBar(wxWindow* parent);
    ~ToolBar();
};


1

3
4
5
6
7
8
9
10
11
12
13
 
//toolbar.cpp

#include "toolbar.h"

ToolBar::ToolBar(wxWindow* parent) : wxAuiToolBar(parent)
{

}

ToolBar::~ToolBar()
{

}


I hope you understand that
