如何在Delphi 7 IDE中将方法挂钩到Edit事件？

Question

当我开始在Delphi 7 IDE中编辑它时,我想自动检出文件.

ClearCase是我的版本控制系统,我真的很讨厌在开始编辑之前签出文件.它总是打破我的思维流程:我正在尝试解决问题,找到我需要更改的地方,尝试编辑它,失败因为文件是只读的,打开clearcase,搜索文件,最后结帐,尝试编辑文件再次失败,因为IDE仍然认为它是只读的,告诉IDE不是readonly.当我最终回到代码时,我忘记了我正在尝试做的事情.

我发现了这个简洁明了的ClearCase IDE集成代码.它可以工作,但使用已弃用的ToolIntf单元.我添加了几个快捷方式.这是它的简化版本(没有尝试编译):

unit clearcase;

interface
uses ToolsApi, ToolIntf;

implementation
uses
  Windows, Dialogs, Classes, ExptIntf, Menus, ShellApi, SysUtils;

type
  TDelphiClearcase = class
  private
    FClearcaseMenu,
    FDoCheckOutPasDfm,
    FDoCheckInPasDfm : TIMenuItemIntf;

    procedure ExecCommand(const command: string; path: PChar = nil);
  public
    destructor Destroy;override;
    procedure DoClick(Sender: TIMenuItemIntf);
    property ClearcaseMenu: TIMenuItemIntf read FClearcaseMenu write FClearcaseMenu;
    property DoCheckOutPasDfm:TIMenuItemIntf write FDoCheckOutPasDfm;
    property DoCheckInPasDfm: TIMenuItemIntf write FDoCheckInPasDfm;
  end;

var
  dcc: TDelphiClearcase = nil;

{ TDelphiClearcase }

destructor TDelphiClearcase.Destroy;
  procedure Remove(item: TIMenuItemIntf);
  begin
    if( item = nil )then
      Exit;
    item.DestroyMenuItem;
    FreeAndNil(item);
  end;
begin
  Remove(FDoCheckOutPasDfm);
  Remove(FDoCheckInPasDfm);
  inherited;
end;

procedure TDelphiClearcase.DoClick(Sender: TIMenuItemIntf);
  function GetPasDfm(const f: string): string;
  var
    aux: string;
  begin
    aux := Copy(f, 1, Length(f) - 4);
    Result := aux + '.pas' + ' ' + aux + '.dfm'
  end;

var
  command, fileName  : string;
begin
  fileName := ToolServices.GetCurrentFile;

  if( Sender = FDoCheckOutPasDfm )then
    command := 'cleartool co ' + GetPasDfm(fileName)
  else if( Sender = FDoCheckInPasDfm )then
    command := 'cleartool ci ' + GetPasDfm(fileName);

  ExecCommand(command);

  ToolServices.ReloadFile(fileName);

end;

procedure TDelphiClearcase.ExecCommand(const command: string; path: PChar);
var
  pi  : TProcessInformation;
  stinfo : TStartupInfo;
begin
  FillChar(stinfo, SizeOf(stinfo), 0);
  stinfo.cb := SizeOf(stinfo);

  if( CreateProcess(nil, PChar(command), nil, nil, True, CREATE_NEW_CONSOLE,
      nil, path, stinfo, pi) )then begin
    WaitForSingleObject(pi.hProcess, INFINITE);
    CloseHandle(pi.hProcess)
  end
end;

procedure CreateMenus;
var
  services: TIToolServices;
begin
  if( BorlandIDEServices = nil )then
    Exit;
  services := ToolServices;

  if( services = nil )then
    Exit;

  dcc := TDelphiClearcase.Create;

  dcc.ClearcaseMenu := services.GetMainMenu.GetMenuItems.InsertItem(6,
    'C&learcase', 'ClearcaseMenu', 'ClearcaseTools', 0, 0, 0,
    [mfEnabled, mfVisible], nil);


  dcc.DoCheckOutPasDfm := dcc.ClearcaseMenu.InsertItem(2,
    'Check Out pas and dfm', 'DoCheckOutPasDfm', 'Undo the check outs', ShortCut(Ord('>'),
    [ssCtrl]), 0, 2,
    [mfEnabled, mfVisible], dcc.DoClick);
  dcc.DoCheckInPasDfm:= dcc.ClearcaseMenu.InsertItem(4,
    'Check In pas and dfm', 'DoCheckInPasDfm', 'Check in current files', ShortCut(Ord('<'),
    [ssCtrl]), 0, 2,
    [mfEnabled, mfVisible], dcc.DoClick);

end;

procedure DestroyMenus;
begin
  FreeAndNil(dcc);
end;

initialization
  CreateMenus;

finalization
  DestroyMenus
end.

我想在我第一次开始编辑它时检查文件并且它是只读的.我不知道如何将函数挂钩到文件的IDE编辑事件.任何指针都是受欢迎的.

编写 API 等的替代方法是简单地使用快照视图并使用“Highjack”功能自动写入文件......然后稍后检查它们。
