请问怎么样判断PANEL中是否有一个FORM在存呢？如果是其它的控件呢？

with (sender as Panel) do
begin
for i:=0 to ControlCount -1 do
begin
if Controls is tform then//判断PANEL中是否是TFORM
showmessage((Controls as tform).caption);
if Controls is tedit then//是否是其它的控件
(Controls as tedit).Clear;
end;
end;
begin
for i:=0 to ControlCount -1 do
begin
if Controls is tform then//判断PANEL中是否是TFORM
showmessage((Controls as tform).caption);
if Controls is tedit then//是否是其它的控件
(Controls as tedit).Clear;
end;
end;

zbwsh说得对所有TControl都有个Controls属性是个数组,里面装的是以这个控件本身为容器的
控件的集合.

procedure TForm1.IsFormHave;
begin
with FormPanel do
begin
if Controls[0] is TChildForm then
// Controls[0].close;
Controls[0].Free;
Controls[0].close;
end;
end;
如果是话，我想释放，可是Controls[0].close;这样不行。请教各位兄台！！
