Cannot create a Pop-up Form in C++ Builder

[Gerhard]

Hi

 

I am new to uniGUI and a C++ programmer. I have a very simple problem, that is to create a form from my main form.

 

In standard C++ i will do it as follows by calling this function from my main form:

 

//---------------------------------------------------------------------------
void __fastcall TResByWebReservationForm201701::UniButton1Click(TObject *Sender)
{
    TPickItemsForm* PickItemsForm= new TPickItemsForm(this);
  PickItemsForm->Show();
}
//---------------------------------------------------------------------------

 

But I get the error:

 

I notice in Pascal the calling convention is different to standard, but have no idea how to call this in C++.

 

1) What is the parameter to call another form?

2) Is there some special code I must enter into the form?

 

Regards

Hi

 

Thanks to Farshad I have this sorted out:

 

For any who is new here are the changes you must make to a new form in C++:

 

1) Under header enter (*.h):

TNewForm* NewForm;

 

2) In the main file enter (*.cpp)

TNewForm *NewForm(void)
{
     return( (TNewForm *)UniMainModule()->GetFormInstance(__classid(TNewForm)));
}
//---------------------------------------------------------------------------

 

Now call the form from Main Form directly as:

NewForm()->Show();

 

Do not create a new instance with new.

Hi

You dont need to make any change at all. Functions are already defined.
