How to retrieve all available TBrushStyle values as a list of strings
Problem/Question/Abstract:
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.
Answer:
You can use runtime type information (RTTI) to do that. Below is an example:
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;
