hex2int example:

var
 strHexVal : string; // hex value
 intVal   : integer;
begin
 strHexVal := '0F';
 intVal := StrToInt('$' + strHexVal);
end;

// the result in intVal will be : 15

// uses FMX.Types
// you can set TVKAutoShowMode = (DefinedBySystem, Never, Always);

FMX.Types.VKAutoShowMode :=TVKAutoShowMode.vkasNever;

// uses FMX.Types

// you can set TVKAutoShowMode = (DefinedBySystem, Never, Always);

FMX.Types.VKAutoShowMode :=TVKAutoShowMode.vkasNever;

obviusly to enable the virtual keyboard:

// uses FMX.Types
// you can set TVKAutoShowMode = (DefinedBySystem, Never, Always);

FMX.Types.VKAutoShowMode :=TVKAutoShowMode.DefinedBySystem;
