Pass working delphi code to c++ builder

[Drummer1972 0]

Hello

 I work with C++ and I need to use this code written in Delphi (it works):

 

Var A:Integer;
Var LastPanel : Double;
Begin
For A:=0 to HorzScrollBox1.Content.ChildrenCount-1 
do TGridLayout (HorzScrollBox1.Content.Children[A].widht:= HorzScrollBox1.width;
HorzScrollBox1.ViewportPosition:=TPointF.Create(LastPanel * HorzScrollBox1.width,0 );
 End;

I have implemented only :

for (int a=0; a<=HorzScrollBox1->Content->ChildrenCount-1;a++)
{
TGridLayout(HorzScrollBox1->Content->Children[a])->Width = HorzScrollBox1->Width}
HorzscrollBox1->ViewportPosition=

On the line : "TGridLayout(HorzScrollBox1->Content->…” 

it gives me the error :

matching conversion for functional-style cast from 'Fmx::Types::TFmxChildrenList' to 'Fmx::Layouts::TGridLayout'"

lso I think that TPointF is a type included in SystemTypes.h.

 

It's possible?. THANKS

What C++ compiler are you using?

Can you post the contents of form file (*.dfm) that corresponds to the two components TGridLayout and HorzScrollBox1. (or create a complete form that is a minimum not-working example) and paste the entire *.dfm file).

Thank you very much for answering..
I use rad studio 11.
Volvo has given me the solution and it is the following:

    for ( int A =  0 ; A < HorzScrollBox1 - > Content - > ChildrenCount ; A ++ ) 
    { 
        static_cast < TGridLayout * > ( HorzScrollBox1 - > Content - > Children - > Items [ A ] ) - > Width = HorzScrollBox1 - > Width ; 
    } 
 
    dobleÚltimoPanel =  1.0 ;  // <--- solo un ejemplo, ponga su valor aquí
  
    HorzScrollBox1 - > ViewportPosition = PointF ( LastPanel * HorzScrollBox1 - > Width, 0.0 ) ;

FWIW the Delphi code doesn't compile. Always paste code that is known to work, rather than copy it out manually.
