13 * Handles resizing of windows, acts as an mediator between MMVimView and
16 * Resizing in windowed mode:
18 * In windowed mode resizing can occur either due to the window frame changing
19 * size (e.g. when the user drags to resize), or due to Vim changing the number
20 * of (rows,columns). The former case is dealt with by letting the vim view
21 * fill the entire content view when the window has resized. In the latter
22 * case we ensure that vim view fits on the screen.
24 * The vim view notifies Vim if the number of (rows,columns) does not match the
25 * current number whenver the view size is about to change. Upon receiving a
26 * dimension change message, Vim notifies the window controller and the window
27 * resizes. However, the window is never resized programmatically during a
28 * live resize (in order to avoid jittering).
30 * The window size is constrained to not become too small during live resize,
31 * and it is also constrained to always fit an integer number of
34 * In windowed mode we have to manually draw a tabline separator (due to bugs
35 * in the way Cocoa deals with the toolbar separator) when certain conditions
36 * are met. The rules for this are as follows:
38 * Tabline visible & Toolbar visible => Separator visible
39 * =====================================================================
40 * NO & NO => YES, if the window is textured
47 * Resizing in full-screen mode:
49 * The window never resizes since it fills the screen, however the vim view may
50 * change size, e.g. when the user types ":set lines=60", or when a scrollbar
53 * It is ensured that the vim view never becomes larger than the screen size
54 * and that it always stays in the center of the screen.
