我正在使用PingTool并且我有一个动态创建按钮的TabSheet(根据用户输入从1-150开始)我希望能够将OnClick命令传递给给定的所有按钮标签页。我的单个按钮单击成功运行我的ping代码,但单击PingAll按钮时收到EStackOverflow消息。任何帮助将不胜感激。代码摘录如下:
用于创建按钮的代码:
begin
For x := 0 to CheckListBox1.Items.Count -1 Do
Begin
If CheckListBox1.Checked[x]=true then
begin
GLCount := (GLCount +1);
theIP :=(CheckListBox1.Items.Strings[x]);
if GLcount < 10 then begin
B := TColorButton.Create(Self);
B.Name:= ('BTN'+intToStr(GLCount+1));
B.Caption := theIP;
B.Parent := TabSheet2;
B.Height := 25;
B.Width := 97;
B.Left := 0 + GLCount * 96;
B.Top := 8;
B.BackColor := clBtnFace;
B.ForeColor := clBtnText;
B.OnClick := CustomButtonClick;
end;
CustomButtonClick代码:
Procedure TForm1.CustomButtonClick(Sender: TObject);
begin
GlobalIP:=TColorButton(Sender).caption;
IdIcmpClient1.Host := GlobalIP;
IdIcmpClient1.ReceiveTimeout := 500;
IdIcmpClient1.Ping();
case IdIcmpClient1.ReplyStatus.ReplyStatusType of
rsEcho:
TColorButton(Sender).BackColor := clGreen;
rsTimeOut:
TColorButton(Sender).BackColor := clRed;
end;
end;
PingAll代码(不工作):
procedure TForm1.PingAllClick(Sender: TObject);
var
i: integer;
begin
For i := 0 to TabSheet2.ControlCount -1 do
if TabSheet2.Controls[i] is TColorButton then
begin
TColorButton(Sender).Click;
end;
end;
答案 0 :(得分:3)
你正在调用recurll的方法PingAllClick ...看你调用TColorButton(发件人)。点击
....
Control := tabSheet2.Controls[i]
if Control is TColorButton then
TColorButton(Control ).Click()
....
