把Delphi5的控件升级到Delphi6(0分)

其实把属性编辑器等引用DesignEditors的部分，
如属性编辑器的声明、实现以及属性编辑器的注册另写一个单元就行了。
下面是一个简单的例子

unit NWDictTreeViewReg;

interface

uses
Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
ComCtrls, Db, DbTables, DesignIntf, DesignEditors;

type
TNamePropertyEditor = class(TPropertyEditor)
public
function GetAttributes: TPropertyAttributes; override;
function GetValue: string; override;
procedure SetValue(const Value: string); override;
end;

TDatabaseNameProperty = class(TNamePropertyEditor)
public
procedure GetValues(Proc: TGetStrProc); override;
end;

TTableNameProperty = class(TNamePropertyEditor)
public
procedure GetValues(Proc: TGetStrProc); override;
end;

TFieldNameProperty = class(TNamePropertyEditor)
public
procedure GetValues(Proc: TGetStrProc); override;
end;

procedure Register;

implementation

uses NWDictTreeView;

procedure Register;
begin
RegisterComponents('NoctWolf DB', [TNWDictTreeView]);
RegisterPropertyEditor(TypeInfo(string), TNWDictTreeView, 'DatabaseName', TDatabaseNameProperty);
RegisterPropertyEditor(TypeInfo(TFileName), TNWDictTreeView, '', TTableNameProperty);
RegisterPropertyEditor(TypeInfo(TFieldName), TNWDictTreeView, '', TFieldNameProperty);
end;

function TNamePropertyEditor.GetAttributes: TPropertyAttributes;
begin
Result := [paValueList, paSortList, paAutoUpdate];
end;

function TNamePropertyEditor.GetValue: string;
begin
Result := GetStrValue;
end;

procedure TDatabaseNameProperty.GetValues(Proc: TGetStrProc);
var
NameStrings: TStrings;
i: Integer;
begin
NameStrings := TStringList.Create;
try
Session.GetDatabaseNames(NameStrings);
for i := 0 to NameStrings.Count - 1 do
begin
Proc(NameStrings);
end;
finally
NameStrings.Free;
end;
end;

procedure TNamePropertyEditor.SetValue(const Value: string);
begin
if GetStrValue <> Value then SetStrValue(Value);
end;

procedure TTableNameProperty.GetValues(Proc: TGetStrProc);
var
NameStrings: TStrings;
i: Integer;
begin
NameStrings := TStringList.Create;
try
Session.GetTableNames((GetComponent(0) as TNWDictTreeView).DatabaseName, '*.*', False, False, NameStrings);
for i := 0 to NameStrings.Count - 1 do
begin
Proc(NameStrings);
end;
finally
NameStrings.Free;
end;
end;

procedure TFieldNameProperty.GetValues(Proc: TGetStrProc);
var
NameStrings: TStrings;
i: Integer;
TempTable: TTable;
begin
NameStrings := TStringList.Create;
TempTable := TTable.Create(GetComponent(0) as TNWDictTreeView);
try
TempTable.DatabaseName := (GetComponent(0) as TNWDictTreeView).DatabaseName;
if (GetName = 'DictRelationParentCodeFieldName') or
(GetName = 'DictRelationCodeFieldName') then
TempTable.TableName := (GetComponent(0) as TNWDictTreeView).DictRelationTableName
else
TempTable.TableName := (GetComponent(0) as TNWDictTreeView).DictTableName;
TempTable.GetFieldNames(NameStrings);
for i := 0 to NameStrings.Count - 1 do
begin
Proc(NameStrings);
end;
finally
TempTable.Free;
NameStrings.Free;
end;
end;


end.

有一些没这么容易，如 TCollectionEditor, TDesignWindow 等，原来的虚拟方法都变了。
你可以试试升级 EhLib。

They changed a lot of little things, but nothing that cannot be worked through. Here's some of the things I can remember that have changed:
1. variants.pas - anywhere variant expressions are being used must have this unit now
2. DesgnIntf --> DesignEditors.pas and DesignIntf.pas
3. DesignIDE.bpl for proxies.pas
4. QConsts.pas - they moved some of the constants around
5. IFormDesigner/TFormDesigner no longer exists, you must use IDesigner with IDesigner.Root as the Form
6. TDesignerSelectionList --> TDesignerSelectionsList
7. FontBCD.pas
8. MaskUtils.pas

谁可以改Topgrid？期待呀！

不可能的。D6有很多方法都改了，一些变量名，单元名都改了，你单改这个是没用的。

接受答案了.
