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:
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;
{...}, 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;
