Re: calling a Event Handler within a class

Show all headers | View raw

Hello, and Thank You @all for ideas and feedback !

It seems, that the thing I would be done, does not
work without a class, and a class member.

I solved the problem, in this form:

//===
class MyDummyClass: public TObject
{
public:
   void __fastcall SpeedButtonClick(System::TObject* Sender) {
     ShowMessage("info speed.");
   }
};
static MyDummyClass * dummyClass = NULL;

extern "C"
__declspec(dllexport) void
__stdcall create__MyCppFrame ( int ParentForm )
{
...
   dummyClass = new MyDummyClass();

   mySpeedButton = new TSpeedButton(myPanel);
   mySpeedButton -> Parent  = myPanel;
   mySpeedButton -> OnClick = &(dummyClass->SpeedButtonClick);
...
}
//===

Thanks for your patient
Jens
