On macOS popping up a menu with a position function that leads the menu to be
under the mouse pointer generates the same initial set of enter events as on
linux, but this is then followed by some leave events and then a repeat of the
same set of enter events.
this exposes what appears to be a logic error in gtk_menu_enter_notify().
Nonlinear enter events (i.e. where the menu pops up under the mouse, so the
mouse was never actually moved into the menu's window) should not cause a reset
of priv->seen_item_enter. This value, when true, is used to force the next
received button release event to be handle as an menu activation event. This
should only happen when the mouse has actually been moved by the user into the
menu (as already indicated in existing comments). The value has this effect by,
on the next enter event for a menu item, if already set, forcing
menu->activate_time to zero, which in turn will cause menu activation on button
up/release.
This bug doesn't appear on Linux (or Windows) because the event sequence
associated with a menu popup is different. The lack of another set of enter
events means that menu->activate_time is never reset, and so the behavior is as
expected.
This change makes the setting of priv->seen_item_enter be idempotent with
respect to non-linear enter events, which I believe is the intended behavior.
YDK2 uses SetSystemUIMode() for fullscreen. This also uses space
otherwise reserved for the menu bar at the top, and is apparently
preferable for Ardour's UI.
However when a user manually enters fullscreen using the window
title-bar's green button (NSWindow toggleFullScreen). YDK will crash
when the user then also tries to use YDK's fullscreen mode:
```
NSWindowStyleMaskFullScreen cleared on a window outside of a full screen transition.
called from
[NSWindow setStyleMask:]
gdk_window_set_decorations
gdk_window_fullscreen
```
Ideally we'd set NSApp presentation flags so that the toplevel window
would allow one to zoom (maximize), but not to enter fullscreen. Like it
used to be on OSX. It is unclear how to achieve this on macOS for
resizable windows, short of marking the top-level window a dialog or
utility window.
macOS has broken its exposure/redraw model at least twice by always providing the entire area
of an NSView for every call to drawRect, and cannot provide the list of rects. This change
expands the tracking done using the needs_display_region, and does so directly via the
objective C methods of an NSView (and its derived children like GdkQuartzView).
The result is that when we send an expose signal, GDK/GTK code can obtain an accurate
list of the invalidated rects if desired, and thus avoiding redrawing the entire contents
of a window
recent gcc (>=11) sets _WIN32_WINNT >= 0x602 which changes
QS_ALLINPUT to include (QS_TOUCH | QS_POINTER) events which are
only available on Windows 8 and later. Listening to those events
makes ardour unresponsive.
