How to declare static variables in Delphi 2009?
17,180
type
TMyClass = class(TObject)
private
class var FX: Integer;
public
class property X: Integer read FX write FX;
end;
or shorter if you don't use a property
type
TMyClass = class(TObject)
public
class var X: Integer;
end;
edit: Note the class in class var. You forgot that part.

P. Duw almost 2 years
I googled,I binged,I already have seen the other "duplicates" here,but none of them work in Delphi 2009 updated up to update 4.
Like in C#,I want to make a static variable in on line or as short as possible.In the end it works like a global variable,but its sorted.
What's the shortest way to do this in delphi 2009?
EDIT
I followed some of your answers,but it doesn't work.
type:
type TmyClass = class(TObject) var staticVar:integer; end;
code:
procedure TForm1.Button1Click(Sender: TObject); var a:integer; begin TMyClass.staticVar := 5; // Line 31 a := TMyClass.staticVar; // Line 32 MessageBox(0,IntToStr(a),'',0); end;
I get the following errors:
[DCC Error] Unit1.pas(31): E2096 Method identifier expected [DCC Error] Unit1.pas(32): E2096 Method identifier expected
