TCnBitBtn 的问题
以前版本作了个软键盘,工作正常。现在突然不能编译。CPU 占用 50% 。
界面不能显示正常,编译时死机。
d2009 相同。好像从去年某个版本开始。以前OK。

和此处代码有关?
for i:= 0 to ComponentCount - 1 do begin
if Components
is TCnBitBtn then
TCnBitBtn(Components
).Cursor:=crHandPoint ;
if TCnBitBtn(Components
).Name='CnBitBtn3' then
TCnBitBtn(Components
).Cursor:=crSizeAll ;
end;

照道理这样的代码不会导致编译器死掉。
您是否装了CnPack IDE专家包或者其它专家包?

原因找到,请大侠解决 代码:1549 行
procedure TCnCustomButton.WMWindowPosChanged(var Message: TMessage);
begin
//Invalidate;注释掉后 OK
inherited;
// 2008年08月03日添加,如果不继承原消息处理将会使控件无法改变大小- -好像就那时更新完后,不能使用不得不全部换成 TSpeedbutton
end;
