bool MythContextPrivate::Init	(	const bool	gui,
		UPnp *	UPnPclient,
		const bool	prompt,
		const bool	noPrompt
	)

bool MythContextPrivate::FindDatabase	(	const bool	prompt,
		const bool	noPrompt
	)

Get database connection settings and test connectivity.

Can use UPnP AutoDiscovery to locate backends, and get their DB settings. The user can force the AutoDiscovery chooser with the --prompt argument, and disable it by using the --disable-autodiscovery argument. There is also an autoconfigure function, which counts the backends, and if there is exactly one, uses it as above.

Despite its name, the disable argument currently only disables the chooser. If set, autoconfigure will still be attempted in some situations.

void MythContextPrivate::TempMainWindow ( bool languagePrompt = true )

Setup a minimal themed main window, and prompt for user's language.

Used for warnings before the database is opened, or bootstrapping pages. After using the window, call EndTempWindow().

Bug:: Some of these settings (e.g. window size, theme) seem to be used after the temp window is destroyed.

Bug:: The default theme here is blue, but as of [12377], G.A.N.T is now meant to be the default? A simple change to make, but Nigel prefers "blue" for these initial screens and popups

void MythContextPrivate::GetScreenBounds ( void )

Get screen size from Qt, respecting for user's multiple screen prefs.

If the windowing system environment has multiple screens (e.g. Xinerama or Mac OS X), QApplication::desktop()->width() will span all of them, so we usually need to get the geometry of a specific screen.

Apply any user overrides to the screen geometry.

void MythContextPrivate::ResetDatabase ( void )

Called when the user changes the DB connection settings.

The current DB connections way be invalid (e.g. wrong password), or the user may have changed to a different database host. Either way, any current connections need to be closed so that the new connection can be attempted.

Any cached settings also need to be cleared, so that they can be re-read from the new database
