带有按钮自定义标题的通用对话框

Question

我知道这个问题从那时起就开始了（例如Best way to show customized message dialogs），但我仍然找不到我想要的东西。

我是这样开始的：

class function TAttracsForm.MessageDlg(const aMsg: string; aDlgType: TMsgDlgType; Buttons: TMsgDlgButtons; aCaptions: array of String; aDefault: TMsgDlgBtn): TModalResult;
var
  vDlg: TForm;
  i: Integer; 
begin
  if aButtons.Count = aCaptions.Count then
  begin
    vDlg := CreateMessageDialog(aMsg, aDlgType, Buttons);
    try
      for i := 0 aCaptions.Count - 1 do
        TButton(vDlg.FindComponent(Buttons[i].Caption)).Caption := aCaptions[i]; 

      vDlg.Position := poDefaultPosOnly;
      Result := vDlg.ShowModal;
    finally
      vDlg.Free;
    end;
  end;
end;

电话会是这样的：

if (MessageDlg('Really quit application ?', mtWarning, 
       [mbNo, mbCancel, mbYes], {'No save', 'Cancel', 'Save'}) = mrYes) then

但上面的代码当然不能编译。我不知道如何在循环中获取一个集合中的一个项目以及如何在开始时获得它的总计数。

您可以使用此代码：

function MyMessageDlg(CONST Msg: string; DlgTypt: TmsgDlgType; button: TMsgDlgButtons;
  Caption: ARRAY OF string; dlgcaption: string): Integer;
var
  aMsgdlg: TForm;
  i: Integer;
  Dlgbutton: Tbutton;
  Captionindex: Integer;
begin
  aMsgdlg := createMessageDialog(Msg, DlgTypt, button);
  aMsgdlg.Caption := dlgcaption;
  aMsgdlg.BiDiMode := bdRightToLeft;
  Captionindex := 0;
  for i := 0 to aMsgdlg.componentcount - 1 Do
  begin
    if (aMsgdlg.components[i] is Tbutton) then
    Begin
      Dlgbutton := Tbutton(aMsgdlg.components[i]);
      if Captionindex <= High(Caption) then
        Dlgbutton.Caption := Caption[Captionindex];
      inc(Captionindex);
    end;
  end;
  Result := aMsgdlg.Showmodal;
end;

例如：

MyMessageDlg('Hello World!', mtInformation, [mbYes, mbNo],
      ['Yessss','Noooo'], 'New MessageDlg Box'):

这样的事情怎么样：

type
  TButtonInfo = record
    MsgDlgBtn: TMsgDlgBtn;
    Caption: string;
  end;

function ButtonInfo(MsgDlgBtn: TMsgDlgBtn; const Caption: string): TButtonInfo;
begin
  Result.MsgDlgBtn := MsgDlgBtn;
  Result.Caption := Caption;
end;

const
  ModalResults: array[TMsgDlgBtn] of Integer = (
    mrYes, mrNo, mrOk, mrCancel, mrAbort, mrRetry, mrIgnore, mrAll, mrNoToAll,
    mrYesToAll, 0, mrClose);

function FindDialogButton(Form: TForm; MsgDlgBtn: TMsgDlgBtn): TButton;
var
  i: Integer;
  Component: TComponent;
begin
  for i := 0 to Form.ComponentCount-1 do begin
    Component := Form.Components[i];
    if Component is TButton then begin
      if TButton(Component).ModalResult=ModalResults[MsgDlgBtn] then begin
        Result := TButton(Component);
        exit;
      end;
    end;
  end;
  Result := nil;
end;

function MessageDlg(
  const aMsg: string;
  aDlgType: TMsgDlgType;
  const Buttons: array of TButtonInfo;
  aDefault: TMsgDlgBtn
): TModalResult;
var
  i: Integer;
  MsgDlgButtons: TMsgDlgButtons;
  vDlg: TForm;
begin
  MsgDlgButtons := [];
  for i := low(Buttons) to high(Buttons) do begin
    Assert(not (Buttons[i].MsgDlgBtn in MsgDlgButtons));//assert uniqueness
    Include(MsgDlgButtons, Buttons[i].MsgDlgBtn);
  end;
  vDlg := CreateMessageDialog(aMsg, aDlgType, MsgDlgButtons, aDefault);
  try
    for i := low(Buttons) to high(Buttons) do begin
      FindDialogButton(vDlg, Buttons[i].MsgDlgBtn).Caption := Buttons[i].Caption;
    end;
    vDlg.Position := poDefaultPosOnly;
    Result := vDlg.ShowModal;
  finally
    vDlg.Free;
  end;
end;

procedure Test;
begin
  MessageDlg(
    'Really quit application ?',
    mtWarning,
    [ButtonInfo(mbNo, 'Do&n''t save'), ButtonInfo(mbCancel, '&Cancel'), ButtonInfo(mbYes,'&Save')],
    mbYes
  );
end;

我写这段代码：（我来自克罗地亚，所以文本是克罗地亚语的

function MojDijalog(const Msg, Capt: string; DlgType: TMsgDlgType; Buttons: TMsgDlgButtons;
  DefaultButton: TMsgDlgBtn): TModalResult;
var
  dlg : TForm;
begin
  dlg := CreateMessageDialog(Msg, DlgType, Buttons, DefaultButton) ;
  with dlg do begin
     Caption := Capt;
     FormStyle := fsStayOnTop;
     ( FindComponent( 'OK' ) as TButton ).Caption := 'U redu' ;
     ( FindComponent( 'Cancel' ) as TButton ).Caption := 'Odustani' ;
     ( FindComponent( 'Yes' ) as TButton ).Caption := 'Da' ;
     ( FindComponent( 'No' ) as TButton ).Caption := 'Ne' ;
      ( FindComponent( 'Help' ) as TButton ).Caption := 'Pomoć' ;
     ( FindComponent( 'Close' ) as TButton ).Caption := 'Zatvori' ;
     ( FindComponent( 'Ignore' ) as TButton ).Caption := 'Zanemari' ;
     ( FindComponent( 'Retry' ) as TButton ).Caption := 'Pokušaj ponovo' ;
     ( FindComponent( 'Abort' ) as TButton ).Caption := 'Prekini' ;
     ( FindComponent( 'All' ) as TButton ).Caption := 'Sve' ;
  end;
  Result := dlg.ShowModal;
end;

使用示例：

if MojDijalog('Obrisati zapis ?','Upit za brisanje',mtConfirmation,mbYesNo,mbNo) = mrNo then
    begin
         Abort;
    end;
