如何在 Inno Setup 中创建新的关于按钮?

Kus*_*hal 1 inno-setup pascalscript

我想在像所有的页面的左下角,以创建一个新的关于按钮wpWelcomewpSelectTaskswpInstalling等; 如果单击它,它将显示一些消息。如果用户按“确定”,消息应关闭。该按钮应显示完整的“关于”一词,而不是“关于...” 我已经CodeClasses.iss在 Inno Setup 中检查过文件,但我不明白我应该复制哪些代码,哪些不应该。

我已经看过这两个帖子:

但它们并不是我真正想要的。

所以请任何人帮忙。

  AboutButton := TNewButton.Create(WizardForm);
  { set the parent to the just created button control }
  AboutButton.Parent := WizardForm;
  { adjust the position to the created button control; it gets the horizontal indent }
  { by the right indent of the Cancel button; the vertical position as well as width }
  { and height are the same as the Cancel button has }
  AboutButton.Left := WizardForm.ClientWidth - WizardForm.CancelButton.Left -

  AboutButton.Caption := '&About';
  { and assign the AboutButtonOnClick method to the OnClick event of the button }
  AboutButton.OnClick := @AboutButtonOnClick;
end;
