// ORGANIZATION: This is a big file. It is (in principle) organized as follows
// (in order):
// 1. Interfaces. Very short, one-time-use classes may include an implementation
// immediately after their interface.
// 2. The general implementation section, ordered as follows:
// i. Public methods and overrides.
// ii. Overrides/implementations of undocumented methods.
// iii. Delegate methods for various protocols, formal and informal, to which
// |BrowserWindowController| conforms.
// 3. (temporary) Implementation sections for various categories.
// Private methods are defined and implemented separately in
// browser_window_controller_private.{h,mm}.
// Not all of the above guidelines are followed and more (re-)organization is
// needed. BUT PLEASE TRY TO KEEP THIS FILE ORGANIZED. I'd rather re-organize as
// little as possible, since doing so messes up the file's history.
// TODO(viettrungluu): [] on-going re-organization, splitting
// things into multiple files -- the plan is as follows:
// - in general, everything stays in browser_window_controller.h, but is split
// off into categories (see below)
// - core stuff stays in
// - ... overrides also stay (without going into a category, in particular)
// - private stuff which everyone needs goes into
// browser_window_controller_private.{h,mm}; if no one else needs them, they
// can go in individual files (see below)
// - area/task-specific stuff go in browser_window_controller_<area>.mm
// - ... in categories called "(<Area>)" or "(<PrivateArea>)"
// Plan of action:
// - first re-organize into categories
// - then split into files
// Notes on self-inflicted (not user-inflicted) window resizing and moving:
// When the bookmark bar goes from hidden to shown (on a non-NTP) page, or when
// the download shelf goes from hidden to shown, we grow the window downwards in
// order to maintain a constant content area size. When either goes from shown
// to hidden, we consequently shrink the window from the bottom, also to keep
// the content area size constant. To keep things simple, if the window is not
// entirely on-screen, we don't grow/shrink the window.
// The complications come in when there isn't enough room (on screen) below the
// window to accomodate the growth. In this case, we grow the window first
// downwards, and then upwards. So, when it comes to shrinking, we do the
// opposite: shrink from the top by the amount by which we grew at the top, and
// then from the bottom -- unless the user moved/resized/zoomed the window, in
// which case we "reset state" and just shrink from the bottom.
// A further complication arises due to the way in which "zoom" ("maximize")
// works on Mac OS X. Basically, for our purposes, a window is "zoomed" whenever
// it occupies the full available vertical space. (Note that the green zoom
// button does not track zoom/unzoomed state per se, but basically relies on
// this heuristic.) We don't, in general, want to shrink the window if the
// window is zoomed (scenario: window is zoomed, download shelf opens -- which
// doesn't cause window growth, download shelf closes -- shouldn't cause the
// window to become unzoomed!). However, if we grew the window
// (upwards/downwards) to become zoomed in the first place, we *should* shrink
// the window by the amounts by which we grew (scenario: window occupies *most*
// of vertical space, download shelf opens causing growth so that window
// occupies all of vertical space -- i.e., window is effectively zoomed,
// download shelf closes -- should return the window to its previous state).
// A major complication is caused by the way grows/shrinks are handled and
// animated. Basically, the BWC doesn't see the global picture, but it sees
// grows and shrinks in small increments (as dictated by the animation). Thus
// window growth/shrinkage (at the top/bottom) have to be tracked incrementally.
// Allowing shrinking from the zoomed state also requires tracking: We check on
// any shrink whether we're both zoomed and have previously grown -- if so, we
// set a flag, and constrain any resize by the allowed amounts. On further
// shrinks, we check the flag (since the size/position of the window will no
// longer indicate that the window is shrinking from an apparent zoomed state)
// and if it's set we continue to constrain the resize.
