Improved implementation of layer-backed views under macOS ≥ 10.14
This new implementation does all screen drawing through the drawRect: method. The benefit is that [[NSGraphicsContext currentContext] CGContext] provides a system-built drawing context whose product ultimately appears on screen. Feed-back from the fldigi FLTK application shows that this procedure is measurably faster that the previous one when drawing a rapidly changing image.

/* Implementation note for the support of layer-backed views.
|
||||
MacOS 10.14 Mojave changes the way all drawing to displays is performed:
|
||||
all NSView objects become layer-backed, that is, the drawing is done by
|
||||
all NSView objects become layer-backed, that is, drawing is done by
|
||||
Core Animation to a CALayer object whose content is then displayed by the NSView.
|
||||
The global variable views_use_CA is set to YES when such change applies,
|
||||
that is, for apps running under 10.14 and linked to SDK 10.14.
|
||||
When views_use_CA is NO, views are not supposed to be layer-backed.
|
||||
|
||||
Each layer-backed non-OpenGL window has a single FLViewLayer object, derived
|
||||
from FLView, which itself has an associated CALayer.
|
||||
FLViewLayer implements displayLayer:. Consequently, FLViewLayer objects are drawn
|
||||
by the displayLayer: method. An FLViewLayer contains also a member variable
|
||||
CGContextRef layer_data, a bitmap context the size of the view (double on Retina).
|
||||
All Quartz drawings go to this bitmap. displayLayer: finishes by using an image copy
|
||||
of the bitmap as the layer's contents. That step fills the window.
|
||||
When resized or when the window flips between low/high resolution displays,
|
||||
FLViewLayer receives the reset_layer_data message which deletes the bitmap and zeroes layer_data.
|
||||
This ensures the bitmap is recreated after the window was resized or changed resolution.
|
||||
Most drawing is done by [FLView drawRect:] which the system calls
|
||||
when a window is created or resized and when Fl_Window_Driver::flush() runs which sends the display
|
||||
message to the view. Within drawRect:, [[NSGraphicsContext currentContext] CGContext]
|
||||
gives a graphics context whose product ultimately appears on screen. But the
|
||||
full content of the view must be redrawn each time drawRect: runs, in contrast
|
||||
to pre-10.14 where drawings were added to the previous window content.
|
||||
That is why FLView maintains a CGImage (view->cgimg) equal to the last content of the FLView.
|
||||
At the beginning of drawRect:, cgimg is drawn to the graphics context and released,
|
||||
then drawRect: does its drawing, finally cgimg is newly set to the
|
||||
view's graphical content as it is at the end of drawRect:.
|
||||
|
||||
Layer-backed OpenGL windows remain processed as before.
|
||||
A problem arises to support drawing done outside Fl_Window_Driver::flush(), that is,
|
||||
after the app calls Fl_Window::make_current() at any time it wants.
|
||||
That situation is identified by the condition (views_use_CA && !through_drawRect).
|
||||
A graphics context usable outside drawRect: that ultimately appears on screen,
|
||||
if it exists, was not identified. Thus, a bitmap graphics context (view->aux_bitmap)
|
||||
is created by function prepare_bitmap_for_layer() with the size of the view
|
||||
(doubled on retina). Drawing operations after the call to Fl_Window::make_current()
|
||||
are directed to this bitmap. Fl_Window::make_current() also calls
|
||||
[view setNeedsDisplay:YES] which instructs the system to run drawRect:
|
||||
at the next event loop. Later, when drawRect: runs, it detects that drawing was
|
||||
sent to aux_bitmap because that pointer is not nil. The content of aux_bitmap
|
||||
is transformed to a CGImage which is assigned to view->cgimg and which is
|
||||
drawn to drawRect's graphics context.
|
||||
|
||||
OpenGL windows remain processed under 10.14 as before.

/*

* make all drawing go into this window (called by subclass flush() impl.)
|
||||
|
||||
This can be called in 3 different instances:
|
||||
This can be called in 3 different situations:
|
||||
|
||||
1) When a window is created or resized.
|
||||
Before 10.14: macOS sends the drawRect: message to the window view after having prepared the
|
||||
current graphics context to draw to this view. Variable through_drawRect is set
|
||||
to YES and calls Fl_Window_Driver::flush().
|
||||
After 10.14: macOS sends the displayLayer: message to the window view. If the layer bitmap
|
||||
does not exist, variable through_Fl_X_flush is set to YES and Fl_Window_Driver::flush() is called.
|
||||
Fl_Window_Driver::flush() calls Fl_Window::flush() that calls Fl_Window::make_current() that
|
||||
uses the graphics context of the window or the layer. The window's draw() function is then executed.
|
||||
After 10.14: the displayLayer method sets the layer's contents to the layer's bitmap.
|
||||
1) When a window is created, resized or moved between low/high resolution displays.
|
||||
macOS sends the drawRect: message to the window view after having prepared the
|
||||
current graphics context to draw to this view. The drawRect: method sets through_drawRect
|
||||
to YES and calls Fl_Window_Driver::flush(). Fl_Window_Driver::flush() calls
|
||||
Fl_Window::flush() that calls Fl_Window::make_current() that uses the graphics
|
||||
context of the window or the layer. The window's draw() function is then executed.
|
||||
|
||||
2) At each round of the FLTK event loop.
|
||||
Fl::flush() is called, that calls Fl_Cocoa_Window_Driver::flush() on each window that needs drawing.
|
||||
Fl_Cocoa_Window_Driver::flush() sets through_Fl_X_Flush to YES and marks the view as
|
||||
needing display.
|
||||
Before 10.14: the view is sent the displayIfNeededIgnoringOpacity message which makes
|
||||
needing display. The view is sent the displayIfNeededIgnoringOpacity or display message which makes
|
||||
the OS send the view the drawRect: message. The program proceeds next as in 1) above.
|
||||
After 10.14: Fl_Window_Driver::flush() is called which draws to the layer bitmap, and
|
||||
the layered view is sent the displayLayer: message at the next event loop.
|
||||
|
||||
3) An FLTK application can call Fl_Window::make_current() at any time before it draws to a window.
|
||||
This occurs for instance in the idle callback function of the mandelbrot test program. Variables
|
||||
through_Fl_X_flush and through_drawRect equal NO. The graphics context of the window
|
||||
or the layer is obtained.
|
||||
Before 10.14: Subsequent drawing requests go to the window.
|
||||
After 10.14: The layered view is marked as needing display. It's sent the display message
|
||||
at the next event loop.
|
||||
through_Fl_X_flush and through_drawRect equal NO.
|
||||
Before 10.14: The window graphics context is obtained. Subsequent drawing requests go to the window.
|
||||
After 10.14: The layered view is marked as needing display. It will be sent the drawRect: message
|
||||
at the next event loop. A temporary bitmap (view->aux_bitmap) is created and subsequent drawing
|
||||
operations, until drawRect: runs, are sent to it.
|
||||
|
||||
CAUTION: it's not possible to call Fl::wait(), Fl::check() nor Fl::ready() while in the draw()
|
||||
function of a widget. Use an idle callback instead.
