Question

我有一个TNewStaticText数据类型的变量，我想为文本设置不同的颜色，例如如果变量包含“有美好的一天”等文本

“Have”应显示为红色 “一个好的”应该以蓝色显示 “day”应以黑色显示

Answer 1

您可以使用Font.Color属性更改字体颜色，但它适用于整个控件的文本。为了您的目标，您需要创建三个控件。这是一个例子：

[Setup]
AppName=My Program
AppVersion=1.5
DefaultDirName={pf}\My Program

[Code]
procedure InitializeWizard;
var
  TopPos: Integer;
  LeftPos: Integer;
  StaticText: TNewStaticText;
begin
  TopPos := WizardForm.NextButton.Top;
  LeftPos := 8;

  StaticText := TNewStaticText.Create(WizardForm);
  StaticText.Parent := WizardForm;
  StaticText.Left := LeftPos;
  StaticText.Top := TopPos;
  StaticText.Font.Color := clRed;
  StaticText.Caption := 'Have ';

  LeftPos := StaticText.Left + StaticText.Width;

  StaticText := TNewStaticText.Create(WizardForm);
  StaticText.Parent := WizardForm;
  StaticText.Left := LeftPos;
  StaticText.Top := TopPos;
  StaticText.Font.Color := clBlue;
  StaticText.Caption := 'a nice ';

  LeftPos := StaticText.Left + StaticText.Width;

  StaticText := TNewStaticText.Create(WizardForm);
  StaticText.Parent := WizardForm;
  StaticText.Left := LeftPos;
  StaticText.Top := TopPos;
  StaticText.Font.Color := clBlack;
  StaticText.Caption := 'day!';
end;

或者，为了使您的代码更加灵活，您可以将此过程包装到如下函数中：

[Setup]
AppName=My Program
AppVersion=1.5
DefaultDirName={pf}\My Program

[Code]
type
  TColorArray = array of TColor;

procedure CreateColoredText(const ATexts: TArrayOfString; const AColors: TColorArray;
  AParent: TWinControl; ALeft, ATop: Integer);
var
  I: Integer;
  LeftPos: Integer;
begin
  if GetArrayLength(ATexts) <> GetArrayLength(AColors) then
    RaiseException('Inconsistent array parameters.');

  LeftPos := ALeft;
  for I := 0 to GetArrayLength(ATexts) - 1 do
  begin
    with TNewStaticText.Create(AParent) do
    begin
      Parent := AParent;
      Left := LeftPos;
      Top := ATop;
      Font.Color := AColors[I];
      Caption := ATexts[I];
      LeftPos := Left + Width;
    end;
  end;
end;

procedure InitializeWizard;
begin
  CreateColoredText(['Have ', 'a nice ', 'day!'], [clRed, clBlue, clBlack],
    WizardForm, 8, WizardForm.NextButton.Top);
end;

你可能想尝试这样的事情：

procedure FormButtonOnClick(Sender: TObject); 
var 
  Form: TSetupForm; 
  OKButton, CancelButton: TNewButton; 
begin 
  Form := CreateCustomForm(); 
  try 
    Form.ClientWidth := ScaleX(256); 
    Form.ClientHeight := ScaleY(256); 
    Form.Caption := 'TSetupForm'; 
    Form.CenterInsideControl(WizardForm, False); 

    OKButton := TNewButton.Create(Form); 
    OKButton.Parent := Form; 
    OKButton.Width := ScaleX(75); 
    OKButton.Height := ScaleY(23); 
    OKButton.Left := Form.ClientWidth - ScaleX(75 + 6 + 75 + 10); 
    OKButton.Top := Form.ClientHeight - ScaleY(23 + 10); 
    OKButton.Caption := 'OK'; 
    OKButton.ModalResult := mrOk; 

    CancelButton := TNewButton.Create(Form); 
    CancelButton.Parent := Form; 
    CancelButton.Width := ScaleX(75); 
    CancelButton.Height := ScaleY(23); 
    CancelButton.Left := Form.ClientWidth - ScaleX(75 + 10); 
    CancelButton.Top := Form.ClientHeight - ScaleY(23 + 10); 
    CancelButton.Caption := 'Cancel'; 
    CancelButton.ModalResult := mrCancel; 
    CancelButton.Cancel := True; 

    Form.ActiveControl := OKButton; 

    if Form.ShowModal() = mrOk then 
      MsgBox('You clicked OK.', mbInformation, MB_OK); 
  finally 
    Form.Free(); 
  end; 
end;
