P.M.
TcnTimerList如何重定义onTimer
我使用了TcnTimerList新建多个计时器,现在想用 自定义函数 处理到时,却不知道怎么做
下面的代码 编译总出错
unit MainForm;
interface
。。。
。。。
type
TForm1 = class(TForm)
。。。
procedure dao(Sender:TObject;PCNum:integer);
。。。
。。。
implementation
。。。
//需要执行的操作
procedure TForm1.dao(Sender:TObject;PCNum:integer);
begin
ShowMessage(IntToStr(PCNum));
end;
procedure createTimerList();
var i:Integer;
begin
for I := 1 to config1.PcNumber do
begin
Form1.ctl1.Items.Add;
Form1.ctl1.Items
.Enabled := False;
Form1.ctl1.Items
.OnTimer := Form1.dao(self,i) ;//接管。编译出错
end;
end;

赋值时,不用写括号与Self吧,后者是调用。

Form1.ctl1.Items.OnTimer := Form1.dao(self,i) ;//接管。编译出错
----------------------
那这一句,我应该怎么写呢
怎么把 i 传递过去呢

I不是在这儿传的,是TCnTimerItem自身在TCnTimerCollection中的Index吧。

对哇,是按顺序加的,I也正好是TCnTimerItem自身在TCnTimerCollection中的Index吧。

是这样,我初始化了(在for循环里动态初始化)好几个tcntimerlist 的item,这样当 一个item到时,我怎么知道是哪个 item呢?
? ?如果用item的index,我在源码里 也没发现 可以在ontimer()里 确定这个item的index的方法
? ?所以我想,在初始化item时,就把 item绑定的 机器号传到 它的ontimer里,这个 item的ontimer后,可以很简单 知道是哪个 机器?

Sender 是 TCnTimerItem,强制转换后它的Index属性就是。

也可以在CnTimerList的OnTimer事件里头直接写,参数中有Index的。
