68 // Bookmark bar state changing and animations
70 // The bookmark bar has three real states: "showing" (a normal bar attached to
71 // the toolbar), "hidden", and "detached" (pretending to be part of the web
72 // content on the NTP). It can, or at least should be able to, animate between
73 // these states. There are several complications even without animation:
74 // - The placement of the bookmark bar is done by the BWC, and it needs to know
75 // the state in order to place the bookmark bar correctly (immediately below
76 // the toolbar when showing, below the infobar when detached).
77 // - The "divider" (a black line) needs to be drawn by either the toolbar (when
78 // the bookmark bar is hidden or detached) or by the bookmark bar (when it is
79 // showing). It should not be drawn by both.
80 // - The toolbar needs to vertically "compress" when the bookmark bar is
81 // showing. This ensures the proper display of both the bookmark bar and the
82 // toolbar, and gives a padded area around the bookmark bar items for right
85 // Our model is that the BWC controls us and also the toolbar. We try not to
86 // talk to the browser nor the toolbar directly, instead centralizing control in
87 // the BWC. The key method by which the BWC controls us is
88 // |-updateState:ChangeType:|. This invokes state changes, and at appropriate
89 // times we request that the BWC do things for us via either the resize delegate
90 // or our general delegate. If the BWC needs any information about what it
91 // should do, or tell the toolbar to do, it can then query us back (e.g.,
92 // |-isShownAs...|, |-getDesiredToolbarHeightCompression|,
93 // |-toolbarDividerOpacity|, etc.).
95 // Animation-related complications:
96 // - Compression of the toolbar is touchy during animation. It must not be
97 // compressed while the bookmark bar is animating to/from showing (from/to
98 // hidden), otherwise it would look like the bookmark bar's contents are
99 // sliding out of the controls inside the toolbar. As such, we have to make
100 // sure that the bookmark bar is shown at the right location and at the
101 // right height (at various points in time).
102 // - Showing the divider is also complicated during animation between hidden
103 // and showing. We have to make sure that the toolbar does not show the
104 // divider despite the fact that it's not compressed. The exception to this
105 // is at the beginning/end of the animation when the toolbar is still
106 // uncompressed but the bookmark bar has height 0. If we're not careful, we
107 // get a flicker at this point.
108 // - We have to ensure that we do the right thing if we're told to change state
109 // while we're running an animation. The generic/easy thing to do is to jump
110 // to the end state of our current animation, and (if the new state change
111 // again involves an animation) begin the new animation. We can do better
112 // than that, however, and sometimes just change the current animation to go
113 // to the new end state (e.g., by "reversing" the animation in the showing ->
114 // hidden -> showing case). We also have to ensure that demands to
115 // immediately change state are always honoured.
117 // Pointers to animation logic:
118 // - |-moveToState:withAnimation:| starts animations, deciding which ones we
119 // know how to handle.
120 // - |-doBookmarkBarAnimation| has most of the actual logic.
121 // - |-getDesiredToolbarHeightCompression| and |-toolbarDividerOpacity| contain
123 // - The BWC's |-layoutSubviews| needs to know how to position things.
124 // - The BWC should implement |-bookmarkBar:didChangeFromState:toState:| and
125 // |-bookmarkBar:willAnimateFromState:toState:| in order to inform the
126 // toolbar of required changes.
