指点合理就有分,只要你有本事,只放三天。(120分)

自己的兴趣，写了个控件，在一般开发，直接设计界面的时候，没有任何问题，组件是能够显示在FORM上的，但用如下代码动态生成时却有问题，组件不显示，请高手指点，如发现代码有不合理的的地方也请一并指点，指点合理就有分，不够可以协商再送，谢谢。

procedure creatld(frmpaper: Tform);
var x:Tlabdbedt;
begin
x:=Tlabdbedt.create(self);
x.top:=10;
x.left:=10;
x.parent:=frmpaper;

end ;



附控件代码

x:=Tlabdbedt.create(self);
-------------------------------
改了没有效果

没有效果，我已经提供了控件的源码，那位大哥仔细看一下指点一下

在create里加下面的代码就可以了
Width := 121;
Height := 25;
TabStop := True;
ParentColor := False;

问题已经解决了，我也拿不回分了，谁帮我看看有没有什么可以要改进的东西，好的建议直接给120分了

靠！解决了不送分啊。

楼主不厚道

什么东西啊，你们都写的什么东西啊，问题没有说到点子上也要分，羞不羞的，分，我自己也拿不回，我当然会给了，关键你自己够不格！没动脑子也想拿分！
标题很清楚：指点合理就有分,只要你有本事

呵呵，惭愧

多人接受答案了。
