Question

所以我知道你可以用.add方法添加一个自定义字段...有什么方法可以删除它吗？

原因是如果选择了一个组件，我只添加字段，如果用户返回，我想删除这些字段，这样它们就不会成倍增加。：）

谢谢！

这是我的.iss :(我打算把代码放在OnBackButtonClick函数中......这就是为什么它在那里;）

Answer 1

当您使用CreateInputDirPage（）时，该页面是TInputDirWizardPage。当你调用.Add（）时，它会返回一个索引，您可以使用该页面的.Buttons [index]，.Edits [index]和.PromptLabels [index]属性来直接访问控件本身。

然后，您可以直接设置.Visible或.Enabled：

DataDirPage.PromptLabels[IndexToDisable].Enabled := false;
DataDirPage.Edits[IndexToDisable].Enabled := false;
DataDirPage.Buttons[IndexToDisable].Enabled := false;

如果存在更多差异，那么更好的选择是拥有两个页面，并且只是跳过ShouldSkipPage（）事件函数中的一个或另一个。
