# wxHtmlModalHelp Class Reference
[Help, HTML]

`#include <wx/html/helpctrl.h>`

## Detailed Description

This class uses wxHtmlHelpController to display help in a modal dialog.

This is useful on platforms such as wxMac where if you display help from a modal dialog, the help window must itself be a modal dialog.

Create objects of this class on the stack, for example:

            // The help can be browsed during the lifetime of this object; when the
            // user quits the help, program execution will continue.
            wxHtmlModalHelp help(parent, "help", "My topic");
