推荐答案

以下全局对象可用: 类型为TMainForm的MainForm，类型为TWizardForm的WizardForm和类型为TUninstallProgressForm的UninstallProgressForm，以及一个特殊的常量:类型为TControl.Cursor的crHand.

The following global objects are available : MainForm of type TMainForm, WizardForm of type TWizardForm and UninstallProgressForm of type TUninstallProgressForm and one special constant: crHand of type TControl.Cursor.

如果要在向导中设置默认目录，只需像使用普通delphi代码一样访问它的组件即可.

If you want to set the default directory in the wizard, just access to it's componants like you would in normal delphi code.

例如，将目录设置为自定义值:

For example, set the directory to a custom value:

WizardForm.DirEdit.Text := 'c:\test';

要读取该值，可以使用WizardDirValue函数.

to read that value you can use the WizardDirValue function.

我说可以访问" ...但是我花了一个小时才弄清楚;)

I say 'just access'... but it took me an hour to figure out ;)
