Detailed Description

wxRegConfig implements the wxConfigBase interface for storing and retrieving configuration information using Windows registry.

This class is used by default for wxConfig on Windows platforms; see wxFileConfig for an alternative you may want to use (also on Windows).

Library: wxBase

Constructor & Destructor Documentation

wxRegConfig::wxRegConfig	(	const wxString &	appName = `wxEmptyString`,
		const wxString &	vendorName = `wxEmptyString`,
		const wxString &	localFilename = `wxEmptyString`,
		const wxString &	globalFilename = `wxEmptyString`,
		long	style = `wxCONFIG_USE_GLOBAL_FILE`
	)

The wxRegConfig constructor.

For more info see the docs for the wxConfigBase::wxConfigBase() constructor.

Note that wxRegConfig's style argument defaults to wxCONFIG_USE_GLOBAL_FILE, i.e. to the use of the HKLM key (also known as "HKEY_LOCAL_MACHINE").
