Add an Infobar style warning for window resize/move

Name of Project

Add an Infobar style warning for window resize/move

Description

Many (poorly behaved) web sites attempt to move and/or resize your browser window. It is possible to stop this behaviour (cf. dom.disable_window_move_resize) but it would be nice to have an infobar that informed the user that a web page attempted to move/resize the window, and allow it or ignore it (default). This behaviour is similar to the current Pop-up Blocker already present in Firefox. NOTE: it is not clear whether such a feature would be accepted in the tree or if this would need to be done as an extension.

• Correction to below... browser.xul is the user interface. It runs functions found in the browser.js file, which then grabs strings from the bundle_browser object in order to display the lines of text.

• I've found the place where infobar text is displayed, and how it is displayed.
  The text can actually be found in a file "\src\browser\base\content\browser.xul". This is what I will use to define a new set of text for a resize event.
  
  In the meantime I am still looking for a way to cause the resize event to display an infobar
• bundle_browser is accessible within the browser object. It contains all the strings from browser.properties.
• by utilizing bundle_browser.GetString("NameofString") you can retrieve the string stored
• inside browser.properties, a %S signifies the browser name.

• It is possible to trigger the event simply by writing code that resizes the window (using SetPositionAndSize I believe?)

09/21/2008 -

• Found two files which might have something to do with this:

dom\src\base\nsGlobalWindow.cpp
dom\src\base\nsGlobalWindow.h

I don't know how useful these files are yet.

• \widget\public\nsGUIEvent.h contains details on the windows_resize event
• The name of the event dealt with is called: nsSizeEvent, a class inherited from nsGUIEvent. A base event.

• Bad news? Looks like I'll need to familiarize myself with the XPCOM API Reference if I want to be able to call Javascript code from the nsWindow.cpp..

• For those who have trouble viewing the source code (It IS very overwhelming at first): http://mxr.mozilla.org/

09/18/2008 -

• Starting a Project Plan. Great idea Dave!

09/14/2008 -

• Created Project page for this project. Its a good reason to keep yourself up to date on the weekly schedule!

Project Plans

09/25/2008 - What to expect for 0.1 release?

• I hope to have a working infobar that displays whenever a site tries to resize the current window. Hopefully I'll have an allow option available. For future releases I will need to allow users to add sites to an exception list, and a way to set it to allow by default.

09/21/2008 -

• Now that I know the name of the event, I need to find a way to cause it to trigger an infobar.
  But that's not all. These are probably the things I expect will need to be covered (from my viewpoint)

• Changes to the infobar to accomodate this
• An option to enable/disable the infobar from popping up in browser config (users know it as about:config)
• Would be nice to know what else I'd need. Anyone with information please let me know

• Reading Documentation on Mozilla's developer site. There's a lot to read: here

09/18/2008 -

• First step would be to see how infobars work in Mozilla. I need to see what triggers one, how they are displayed as well as how they can be used. If they can alter the content on a page, that would be an interesting find also.
• Would be a good idea to also look up what event handlers there are.
