/**
|
||||
* PrintUtils is a utility for front-end code to trigger common print
|
||||
* operations (printing, show print preview, show page settings).
|
||||
*
|
||||
* Unfortunately, likely due to inconsistencies in how different operating
|
||||
* systems do printing natively, our XPCOM-level printing interfaces
|
||||
* are a bit confusing and the method by which we do something basic
|
||||
* like printing a page is quite circuitous.
|
||||
*
|
||||
* To compound that, we need to support remote browsers, and that means
|
||||
* kicking off the print jobs in the content process. This means we send
|
||||
* messages back and forth to that process. browser-content.js contains
|
||||
* the object that listens and responds to the messages that PrintUtils
|
||||
* sends.
|
||||
*
|
||||
* PrintUtils sends messages at different points in its implementation, but
|
||||
* their documentation is consolidated here for ease-of-access.
|
||||
*
|
||||
*
|
||||
* Messages sent:
|
||||
*
|
||||
* Printing:Print
|
||||
* This message is sent to kick off a print job for a particular content
|
||||
* window (which is passed along with the message). We also pass print
|
||||
* settings with this message - though bug 1088070 will have us gather
|
||||
* those settings from the content process instead.
|
||||
*
|
||||
* Printing:Preview:Enter
|
||||
* This message is sent to put content into print preview mode. We pass
|
||||
* the content window of the browser we're showing the preview of, and
|
||||
* the target of the message is the browser that we'll be showing the
|
||||
* preview in. We also pass print settings in this message, but
|
||||
* bug 1088070 will have us gather those settings from the content process
|
||||
* instead.
|
||||
*
|
||||
* Printing:Preview:Exit
|
||||
* This message is sent to take content out of print preview mode.
|
||||
*
|
||||
*
|
||||
* Messages Received
|
||||
*
|
||||
* Printing:Preview:Entered
|
||||
* This message is sent by the content process once it has completed
|
||||
* putting the content into print preview mode. We must wait for that to
|
||||
* to complete before switching the chrome UI to print preview mode,
|
||||
* otherwise we have layout issues.
|
||||
*
|
||||
* Printing:Preview:StateChange, Printing:Preview:ProgressChange
|
||||
* Due to a timing issue resulting in a main-process crash, we have to
|
||||
* manually open the progress dialog for print preview. The progress
|
||||
* dialog is opened here in PrintUtils, and then we listen for update
|
||||
* messages from the child. Bug 1088061 has been filed to investigate
|
||||
* other solutions.
