TEdit verursacht crash

[Borni]

Wir umgehen das ganze jetzt und überschreiben die original Routine, damit läuft es jetzt einwandfrei

Code:

{$IF DEFINED(iOS) or DEFINED(ANDROID)}
  var
    KeyboardDist : Single;
    FKBBounds: TRectF;
    Control: TControl;
{$ENDIF}

procedure Tmainform.FormVirtualKeyboardHidden(Sender: TObject; KeyboardVisible: Boolean; const Bounds: TRect);
begin
  {$IF DEFINED(iOS) or DEFINED(ANDROID)}
    if FocusedControl <> nil then
      if ((FocusedControl as TControl).Name = 'OriginText') or ((FocusedControl as TControl).Name = 'DestinationText') then
        begin
          Control := FindControlByName(SnapInLayout, 'RouteAddresses');
          if Assigned(Control) and (Control is TRectangle) then
            TRectangle(Control).Height := KeyboardDist;
        end;
    FKBBounds.Create(0, 0, 0, 0);
  {$ENDIF}
end;

procedure Tmainform.FormVirtualKeyboardShown(Sender: TObject; KeyboardVisible: Boolean; const Bounds: TRect);
{$IF DEFINED(iOS) or DEFINED(ANDROID)}
var
  Factor : Integer;
{$ENDIF}

begin
  {$IF DEFINED(iOS) or DEFINED(ANDROID)}
    try
      if (Screen.FocusControl <> nil) and (Screen.FocusControl is TMemo) then
        FocusedControl := TControl(Screen.FocusControl);
    except
      on E: Exception do
        Showmessage(E.Message);
    end;
    if FocusedControl <> nil then
      if (FocusedControl.Name = 'OriginText') or (FocusedControl.Name = 'DestinationText') then
        begin
          FKBBounds := TRectF.Create(Bounds);
          FKBBounds.TopLeft := ScreenToClient(FKBBounds.TopLeft);
          FKBBounds.BottomRight := ScreenToClient(FKBBounds.BottomRight);
          Control := FindControlByName(SnapInLayout, 'RouteAddresses');
          if FocusedControl.Name = 'OriginText' then
            Factor := 2
          else
            Factor := 1;
          if Assigned(Control) and (Control is TRectangle) then
            if Height - (FocusedControl.LocalToAbsolute(PointF(0, 0)).Y + FocusedControl.Height * Factor + 5)
               < FKBBounds.Height then
              begin
                KeyboardDist := TRectangle(Control).Height;
                TRectangle(Control).Height := TRectangle(Control).Height + (FKBBounds.Height -
                (Height - (FocusedControl.LocalToAbsolute(PointF(0, 0)).Y +
                     FocusedControl.Height * Factor + 5)));
              end;
      end;
  {$ENDIF}
end;
