WxWidgets: Troubling Callling wxFrame ConstructorE

Okay, I have run into a really bizarre problem.

I have a wxWidgets program that has two frames, a main one, and a secondary one.

The main one has a button that calls the second one to open.

I had trouble with calling a derived class from the second wxframe's class, so I moved the declaration/implementation of the class to before the class for the main frame.

Now I am getting a compile error.

Here is the header file containing the derived wxFrame classes:

This is the error I am getting: \ NUEMain.h|23|error: no matching function for call to 'AssetEd::AssetEd()'|

This is an error calling the constructor in the parent class, but I merely copied the way it was done for the original frame, which worked fine.

What is up?

EDIT 1:

Okay, I replaced

NUEAsset(wxFrame *frame){} 

with

NUEAsset(wxFrame *frame): AssetEd(frame){}

and it now fails in the linking stage with the following error:

)]+0x7e)||undefined reference to `vtable for NUEAsset'|

I can't make heads or tails of this error.

EDIT 2:

Oh, and I keep getting this warning as well, but I have been ignoring it. Could this be related:

||warning: auto-importing has been activated without --enable-auto-import specified on the command line.|

EDIT 3: I think I solved the problem using the information below and some digging.

It turns out that I was defining some events for a frame that no longer had those events.

Changed the defs, and it seems to work now.

AssetEd does not have a default constructor. If you define any constructor of your own, the default constructor will not be implicitly provided.

The problem is that the base object of a derived class needs to be constructed somehow. If you don't call a suitable constructor from the initializer list, the default constructor will be used implicitly.

NUEAsset must simply invoke the constructor of the base class with suitable arguments, e.g

NUEAsset(wxFrame *frame): Asset(frame) {}
