| 44 | // This module implements the UI support in Chrome for cloud printing. |
| 45 | // This means hosting a dialog containing HTML/JavaScript and using |
| 46 | // the published cloud print user interface integration APIs to get |
| 47 | // page setup settings from the dialog contents and provide the |
| 48 | // generated print PDF to the dialog contents for uploading to the |
| 49 | // cloud print service. |
| 50 | |
| 51 | // Currently, the flow between these classes is as follows: |
| 52 | |
| 53 | // PrintDialogCloud::CreatePrintDialogForPdf is called from |
| 54 | // resource_message_filter_gtk.cc once the renderer has informed the |
| 55 | // renderer host that PDF generation into the renderer host provided |
[email protected] | 032682b | 2011-01-12 22:05:02 | [diff] [blame] | 56 | // temp file has been completed. That call is on the FILE thread. |
[email protected] | 73852b8f | 2010-05-14 00:38:12 | [diff] [blame] | 57 | // That, in turn, hops over to the UI thread to create an instance of |
| 58 | // PrintDialogCloud. |
| 59 | |
| 60 | // The constructor for PrintDialogCloud creates a |
| 61 | // CloudPrintHtmlDialogDelegate and asks the current active browser to |
| 62 | // show an HTML dialog using that class as the delegate. That class |
| 63 | // hands in the kCloudPrintResourcesURL as the URL to visit. That is |
| 64 | // recognized by the GetDOMUIFactoryFunction as a signal to create an |
| 65 | // ExternalHtmlDialogUI. |
| 66 | |
| 67 | // CloudPrintHtmlDialogDelegate also temporarily owns a |
| 68 | // CloudPrintFlowHandler, a class which is responsible for the actual |
| 69 | // interactions with the dialog contents, including handing in the PDF |
| 70 | // print data and getting any page setup parameters that the dialog |
| 71 | // contents provides. As part of bringing up the dialog, |
| 72 | // HtmlDialogUI::RenderViewCreated is called (an override of |
| 73 | // DOMUI::RenderViewCreated). That routine, in turn, calls the |
| 74 | // delegate's GetDOMMessageHandlers routine, at which point the |
| 75 | // ownership of the CloudPrintFlowHandler is handed over. A pointer |
| 76 | // to the flow handler is kept to facilitate communication back and |
| 77 | // forth between the two classes. |
| 78 | |
| 79 | // The DOMUI continues dialog bring-up, calling |
| 80 | // CloudPrintFlowHandler::RegisterMessages. This is where the |
| 81 | // additional object model capabilities are registered for the dialog |
| 82 | // contents to use. It is also at this time that capabilities for the |
| 83 | // dialog contents are adjusted to allow the dialog contents to close |
| 84 | // the window. In addition, the pending URL is redirected to the |
| 85 | // actual cloud print service URL. The flow controller also registers |
| 86 | // for notification of when the dialog contents finish loading, which |
| 87 | // is currently used to send the PDF data to the dialog contents. |
| 88 | |
| 89 | // In order to send the PDF data to the dialog contents, the flow |
| 90 | // handler uses a CloudPrintDataSender. It creates one, letting it |
| 91 | // know the name of the temporary file containing the PDF data, and |
| 92 | // posts the task of reading the file |
| 93 | // (CloudPrintDataSender::ReadPrintDataFile) to the file thread. That |
| 94 | // routine reads in the file, and then hops over to the IO thread to |
| 95 | // send that data to the dialog contents. |
| 96 | |
| 97 | // When the dialog contents are finished (by either being cancelled or |
| 98 | // hitting the print button), the delegate is notified, and responds |
| 99 | // that the dialog should be closed, at which point things are torn |
| 100 | // down and released. |
| 101 | |
| 102 | // TODO(scottbyer): |
| 103 | // http://code.google.com/p/chromium/issues/detail?id=44093 The |
| 104 | // high-level flow (where the PDF data is generated before even |
| 105 | // bringing up the dialog) isn't what we want. |
