灵异事件，我自定义的MyTreeView遁了

[wugangcn]

说的不准确，是MyTreeView从来没在工程中出现，所以我应该没有机会去隐藏它，一个单元内在它之前和之后的控件都有显示，就它不出来，在palette属性里能看到它，里dpk或其它设计控件的PAS里能在palette上看来它，一进工程或者普通PAS就看不到了。

不光是treeview 我定义listview也不成功,不能成功显示在palette,在属性里查，却是存在

是不是长宽高太少了，或是太长，呵呵

[wugangcn]

unit MyBoxes;
interface
uses
SysUtils, Classes, Controls, StdCtrls,QComCtrls;
type
TMyCheckBox = class(TCheckBox)
private
{ Private declarations }
protected
{ Protected declarations }
public
{ Public declarations }
published
{ Published declarations }
end;
type
TMyTreeView = class(TTreeView)
private
{ Private declarations }
protected
{ Protected declarations }
public
{ Public declarations }
published
{ Published declarations }
end;
type
TMyListView = class(TListView)
private
{ Private declarations }
protected
{ Protected declarations }
public
{ Public declarations }
published
{ Published declarations }
end;
type
TMyComboBox = class(TComboBox)
private
{ Private declarations }
protected
{ Protected declarations }
public
{ Public declarations }
published
{ Published declarations }
end;
procedure Register;
implementation

procedure Register;
begin
RegisterComponents('Favor', [TMyCheckBox,TMyTreeView,TMyListView,TMyComboBox]);
end;
end.
准确说，我什么都没写，MycheckBox和MyCombox有显示，TreeView和ListView

怎么会有QComCtrls？不要用这个，这个是CLX的。用VCL的ComCtrls。

问题应该就是出在这里

我还有注意这一点，但还是搞错了，搞得我用delphi自动生成一个，郁闷了很久.谢谢.
