inno-setup - Inno Setup 中的条件 DisableProgramGroupPage

Question

我正在尝试为普通安装和可移植安装创建一个安装程序。对于可移植安装，我禁用所有图标和卸载程序创建。

我遇到的唯一问题是如何在运行可移植安装时禁用程序组页面。我在这里误解了什么吗？

[Setup]
;This works as expected
Uninstallable=not IsPortable()
;This does NOT work, can't compile (DisableProgramGroupPage=yes alone compiles fine)
DisableProgramGroupPage=yes IsPortable()

编译失败并报错

Value of [Setup] section directive ... is invalid.

这是 IsPortable()功能:

function IsPortable(): Boolean;
begin
  if(StandardRadioButton.Checked = True) then
  Result := False
  else
  Result := True;
end;

Answer 1

(详细说明@TLama 的评论)

DisableProgramGroupPage 不支持“ bool 表达式”:

[Setup]: DisableProgramGroupPage
Valid values: auto, yes, or no

与 Uninstallable 相反:

[Setup]: Uninstallable
Valid values: yes or no, or a boolean expression

您可以使用 ShouldSkipPage event function反而:

function ShouldSkipPage(PageID: Integer): Boolean;
begin
  Result := False;

  if PageID = wpSelectProgramGroup then
  begin
    Result := IsPortable;
  end;
end;
