// This module implements the UI support in Chrome for cloud printing.
// This means hosting a dialog containing HTML/JavaScript and using
// the published cloud print user interface integration APIs to get
// page setup settings from the dialog contents and provide the
// generated print data to the dialog contents for uploading to the
// cloud print service.
// Currently, the flow between these classes is as follows:
// PrintDialogCloud::CreatePrintDialogForFile is called from
// resource_message_filter_gtk.cc once the renderer has informed the
// renderer host that print data generation into the renderer host provided
// temp file has been completed. That call is on the FILE thread.
// That, in turn, hops over to the UI thread to create an instance of
// PrintDialogCloud.
// The constructor for PrintDialogCloud creates a
// CloudPrintWebDialogDelegate and asks the current active browser to
// show an HTML dialog using that class as the delegate. That class
// hands in the kChromeUICloudPrintResourcesURL as the URL to visit. That is
// recognized by the GetWebUIFactoryFunction as a signal to create an
// ExternalWebDialogUI.
// CloudPrintWebDialogDelegate also temporarily owns a
// CloudPrintFlowHandler, a class which is responsible for the actual
// interactions with the dialog contents, including handing in the
// print data and getting any page setup parameters that the dialog
// contents provides. As part of bringing up the dialog,
// WebDialogUI::RenderViewCreated is called (an override of
// WebUI::RenderViewCreated). That routine, in turn, calls the
// delegate's GetWebUIMessageHandlers routine, at which point the
// ownership of the CloudPrintFlowHandler is handed over. A pointer
// to the flow handler is kept to facilitate communication back and
// forth between the two classes.
// The WebUI continues dialog bring-up, calling
// CloudPrintFlowHandler::RegisterMessages. This is where the
// additional object model capabilities are registered for the dialog
// contents to use. It is also at this time that capabilities for the
// dialog contents are adjusted to allow the dialog contents to close
// the window. In addition, the pending URL is redirected to the
// actual cloud print service URL. The flow controller also registers
// for notification of when the dialog contents finish loading, which
// is currently used to send the data to the dialog contents.
// In order to send the data to the dialog contents, the flow
// handler uses a CloudPrintDataSender. It creates one, letting it
// know the name of the temporary file containing the data, and
// posts the task of reading the file
// (CloudPrintDataSender::ReadPrintDataFile) to the file thread. That
// routine reads in the file, and then hops over to the IO thread to
// send that data to the dialog contents.
// When the dialog contents are finished (by either being cancelled or
// hitting the print button), the delegate is notified, and responds
// that the dialog should be closed, at which point things are torn
// down and released.
