Как сделать текстовый список всех доступных свойств перечисляемого типа?

I need to get a list of strings (like a StringList) with the possible values for a TBrushStyle property (bsSolid, bsClear, bsHorizontal, for example). I want to build a ComboBox with this options. How can I set the property Items of my ComboBox directly with all the values from the enumerated type TBrushStyle? My ComboBox will be alike the Property Editor for this type.

 

You can use runtime type information (RTTI) to do that. Below is an example:

 

Code:

uses

{...}, TypInfo

 

procedure BrushStylesAsStrings(AList: TStrings);

var

a: integer;

pInfo: PTypeInfo;

pEnum: PTypeData;

begin

AList.Clear;

pInfo := PTypeInfo(TypeInfo(TBrushStyle));

pEnum := GetTypeData(pInfo);

with pEnum^ do

begin

   for a := MinValue to MaxValue do

     AList.Add(GetEnumName(pInfo, a));

end;

end;
