FLView is an FLTK-defined NSView subclass that implements the NSTextInputClient protocol to properly handle text input. It also implements the old NSTextInput protocol to run with OS <= 10.4. The few NSTextInput protocol methods that differ in signature from the NSTextInputClient protocol transmit the received message to the corresponding NSTextInputClient method. Keyboard input sends keyDown: and performKeyEquivalent: messages to myview. The latter occurs for keys such as ForwardDelete, arrows and F1, and when the Ctrl or Cmd modifiers are used. Other key presses send keyDown: messages. The keyDown: method calls [myview process_keydown:theEvent] that is equivalent to [[myview inputContext] handleEvent:theEvent], and triggers system processing of keyboard events. The performKeyEquivalent: method directly calls Fl::handle(FL_KEYBOARD, focus-window) when the Ctrl or Cmd modifiers are used. If not, it also calls [[myview inputContext] handleEvent:theEvent]. The performKeyEquivalent: method returns YES when the keystroke has been handled and NO otherwise, which allows shortcuts of the system menu to be processed. Three sorts of messages are then sent back by the system to myview: doCommandBySelector:, setMarkedText: and insertText:. All 3 messages eventually produce Fl::handle(FL_KEYBOARD, win) calls. The doCommandBySelector: message allows to process events such as new-line, forward and backward delete, arrows, escape, tab, F1. The message setMarkedText: is sent when marked text, that is, temporary text that gets replaced later by some other text, is inserted. This happens when a dead key is pressed, and also when entering complex scripts (e.g., Chinese). Fl_X::next_marked_length gives the byte length of marked text before the FL_KEYBOARD event is processed. Fl::compose_state gives this length after this processing. Message insertText: is sent to enter text in the focused widget. If there's marked text, Fl::compose_state is > 0, and this marked text gets replaced by the inserted text. If there's no marked text, the new text is inserted at the insertion point. When the character palette is used to enter text, the system sends an insertText: message to myview. The in_key_event field of the FLView class allows to differentiate keyboard from palette inputs. During processing of the handleEvent message, inserted and marked strings are concatenated in a single string inserted in a single FL_KEYBOARD event after return from handleEvent. The need_handle member variable of FLView allows to determine when setMarkedText or insertText strings have been sent during handleEvent processing and must trigger an FL_KEYBOARD event. Concatenating two insertText operations or an insertText followed by a setMarkedText is possible. In contrast, setMarkedText followed by insertText or by another setMarkedText isn't correct if concatenated in a single string. Thus, in such case, the setMarkedText and the next operation produce each an FL_KEYBOARD event. OS >= 10.7 contains a feature where pressing and holding certain keys opens a menu window that shows a list of possible accented variants of this key. The selectedRange field of the FLView class and the selectedRange, insertText: and setMarkedText: methods of the NSTextInputClient protocol are used to support this feature. The notion of selected text (!= marked text) is monitored by the selectedRange field. The -(NSRange)[FLView selectedRange] method is used to control whether an FLTK widget opens accented character windows by returning .location = NSNotFound to disable that, or returning the value of the selectedRange field to enable the feature. When selectedRange.location >= 0, the value of selectedRange.length is meaningful. 0 means no text is currently selected, > 0 means this number of characters before the insertion point are selected. The insertText: method does selectedRange = NSMakeRange(100, 0); to indicate no text is selected. The setMarkedText: method does selectedRange = NSMakeRange(100, newSelection.length); to indicate that this length of text is selected. With OS <= 10.5, the NSView class does not implement the inputContext message. [myview process_keydown:theEvent] is equivalent to [[FLTextInputContext singleInstance] handleEvent:theEvent]. Method +[FLTextInputContext singleInstance] returns an instance of class FLTextInputContext that possesses a handleEvent: method. The class FLTextView implements the so-called view's "field editor". This editor is an instance of the FLTextView class allocated by the -(id)[FLWindowDelegate windowWillReturnFieldEditor: toObject:] method. The -(BOOL)[FLTextInputContext handleEvent:] method emulates the missing 10.6 -(BOOL)[NSTextInputContext handleEvent:] by sending the interpretKeyEvents: message to the FLTextView object. The system sends back doCommandBySelector: and insertText: messages to the FLTextView object that are transmitted unchanged to myview to be processed as with OS >= 10.6. The system also sends setMarkedText: messages directly to myview. There is furthermore an oddity of dead key processing with OS <= 10.5. It occurs when a dead key followed by a non-accented key are pressed. Say, for example, that keys '^' followed by 'p' are pressed on a French or German keyboard. Resulting messages are: [myview setMarkedText:@"^"], [myview insertText:@"^"], [myview insertText:@"p"], [FLTextView insertText:@"^p"]. The 2nd '^' replaces the marked 1st one, followed by p^p. The resulting text in the widget is "^p^p" instead of the desired "^p". To avoid that, the FLTextView object is deactivated by the insertText: message and reactivated after the handleEvent: message has been processed. NSEvent's during a character composition sequence: - keyDown with deadkey -> [[theEvent characters] length] is 0 - keyUp -> [theEvent characters] contains the deadkey - keyDown with next key -> [theEvent characters] contains the composed character - keyUp -> [theEvent characters] contains the standard character */ static void cocoaKeyboardHandler(NSEvent *theEvent) { NSUInteger mods; // get the modifiers mods = [theEvent modifierFlags]; // get the key code UInt32 keyCode = 0, maskedKeyCode = 0; unsigned short sym = 0; keyCode = [theEvent keyCode]; // extended keyboards can also send sequences on key-up to generate Kanji etc. codes. // Some observed prefixes are 0x81 to 0x83, followed by an 8 bit keycode. // In this mode, there seem to be no key-down codes // printf("%08x %08x %08x\n", keyCode, mods, key); maskedKeyCode = keyCode & 0x7f; mods_to_e_state( mods ); // process modifier keys if (!macKeyLookUp) macKeyLookUp = fl_compute_macKeyLookUp(); sym = macKeyLookUp[maskedKeyCode]; if (sym < 0xff00) { // a "simple" key // find the result of this key without modifier NSString *sim = [theEvent charactersIgnoringModifiers]; UniChar one; CFStringGetCharacters((CFStringRef)sim, CFRangeMake(0, 1), &one); // charactersIgnoringModifiers doesn't ignore shift, remove it when it's on if(one >= 'A' && one <= 'Z') one += 32; if (one > 0 && one <= 0x7f && (sym<'0' || sym>'9') ) sym = one; } Fl::e_keysym = Fl::e_original_keysym = sym; /*NSLog(@"cocoaKeyboardHandler: keycode=%08x keysym=%08x mods=%08x symbol=%@ (%@)", keyCode, sym, mods, [theEvent characters], [theEvent charactersIgnoringModifiers]);*/ // If there is text associated with this key, it will be filled in later.

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 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 which itself has an associated CALayer. FLViewLayer implements displayLayer:. Consequently, FLViewLayer objects are drawn by the displayLayer: method. An FLViewLayer manages 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. updateLayer finishes by using an image copy of the bitmap as the layer's contents. That step fills the window. FLViewLayer implements viewFrameDidChange which deletes the bitmap and zeros layer_data. This ensures the bitmap is recreated when the window is resized. viewFrameDidChange is also called when the window flips between low/high resolution displays. Each layer-backed OpenGL window has an associated FLGLViewLayer object, derived from FLView. FLGLViewLayer objects are drawn by the displayLayer: method which calls drawRect: which draws the GL scene. */ #if MAC_OS_X_VERSION_MAX_ALLOWED >= MAC_OS_X_VERSION_10_8 static CGContextRef prepare_bitmap_for_layer(int w, int h ) { CGColorSpaceRef cspace = CGColorSpaceCreateDeviceRGB(); CGContextRef gc = CGBitmapContextCreate(NULL, w, h, 8, 4 * w, cspace, kCGImageAlphaPremultipliedFirst); CGColorSpaceRelease(cspace); CGContextClearRect(gc, CGRectMake(0,0,w,h)); return gc; } @interface FLGLViewLayer : FLView // for layer-backed GL windows #if MAC_OS_X_VERSION_MAX_ALLOWED >= MAC_OS_X_VERSION_10_12 < CALayerDelegate > #endif - (void)displayLayer:(CALayer *)layer; - (void)drawRect:(NSRect)rect; - (BOOL)wantsLayer; - (BOOL)did_view_resolution_change; @end @implementation FLGLViewLayer - (void)displayLayer:(CALayer *)layer { [self drawRect:[self frame]]; } - (void)drawRect:(NSRect)rect { fl_lock_function(); Fl_Window *window = [(FLWindow*)[self window] getFl_Window]; Fl_X *i = Fl_X::i( window ); if (!Fl::use_high_res_GL() && fl_mac_os_version < 101401) [self layer].contentsScale = 1.; [self did_view_resolution_change]; window->clear_damage(FL_DAMAGE_ALL); i->flush(); window->clear_damage(); if (window->parent() && fl_mac_os_version < 101401) window->redraw(); // useful during resize of GL subwindow fl_unlock_function(); } -(BOOL)wantsLayer { return YES; } - (BOOL)did_view_resolution_change { BOOL retval = [super did_view_resolution_change]; if (retval && Fl::use_high_res_GL()) { Fl_Window *window = [(FLWindow*)[self window] getFl_Window]; Fl_X *i = Fl_X::i( window ); [self layer].contentsScale = i->mapped_to_retina() ? 2. : 1.; window->redraw(); // necessary with 10.14.2 public beta 3 } return retval; } @end @implementation FLViewLayer - (BOOL)wantsLayer { return YES; } - (void)displayLayer:(CALayer *)layer { // called if views are layered (but not for GL) : all drawing to window goes through this Fl_Window *window = [(FLWindow*)[self window] getFl_Window]; Fl_X *i = Fl_X::i( window ); if (!layer_data) { // runs when window is created, resized, changed screen resolution NSRect r = [self frame]; layer.bounds = NSRectToCGRect(r); [self did_view_resolution_change]; i->wait_for_expose = 0; if (i->mapped_to_retina()) { r.size.width *= 2; r.size.height *= 2; layer.contentsScale = 2.; } else layer.contentsScale = 1.; layer_data = prepare_bitmap_for_layer(r.size.width, r.size.height); Fl_X *i = Fl_X::i(window); if ( i->region ) { XDestroyRegion(i->region); i->region = 0; } window->clear_damage(FL_DAMAGE_ALL); } if (window->damage()) { through_drawRect = YES; i->flush(); Fl_X::q_release_context(); through_drawRect = NO; window->clear_damage(); if (layer_data) { CGImageRef cgimg = CGBitmapContextCreateImage(layer_data); // requires 10.4 layer.contents = (id)cgimg; CGImageRelease(cgimg); } } } - (BOOL)did_view_resolution_change { BOOL retval = [super did_view_resolution_change]; if (retval) { [self viewFrameDidChange]; [self displayLayer:[self layer]]; // useful for Mandelbrot to recreate the layer's bitmap } return retval; } -(void)viewFrameDidChange { CGContextRelease(layer_data); layer_data = NULL; } -(void)dealloc { CGContextRelease(layer_data); [super dealloc]; } @end #endif //>= MAC_OS_X_VERSION_10_8 @implementation FLView - (BOOL)did_view_resolution_change { #if MAC_OS_X_VERSION_MAX_ALLOWED >= MAC_OS_X_VERSION_10_7 if (fl_mac_os_version >= 100700) { // determine whether window is mapped to a retina display Fl_Window *window = [(FLWindow*)[self window] getFl_Window]; Fl_X *i = Fl_X::i( window ); bool previous = i->mapped_to_retina(); NSSize s = [self convertSizeToBacking:NSMakeSize(10, 10)]; // 10.7 i->mapped_to_retina( int(s.width + 0.5) > 10 ); BOOL retval = (i->wait_for_expose == 0 && previous != i->mapped_to_retina()); if (retval) i->changed_resolution(true); return retval; } #endif return NO; } - (BOOL)process_keydown:(NSEvent*)theEvent { id o = fl_mac_os_version >= 100600 ?

This can be called in 3 different instances: 1) When a window is created or resized. The system sends the drawRect: message to the window's view after having prepared the current graphics context to draw to this view. Processing of drawRect: sets variable through_drawRect to YES and calls handleUpdateEvent() that calls Fl_X::flush(). Fl_X::flush() sets through_Fl_X_flush to YES and calls Fl_Window::flush() that calls Fl_Window::make_current() that uses the window's graphics context. The window's draw() function is then executed. 2) At each round of the FLTK event loop. Fl::flush() is called, that calls Fl_X::flush() on each window that needs drawing. Variable through_Fl_X_flush is set to YES. Fl_X::flush() locks the focus to the view and calls Fl_Window::flush() that calls Fl_Window::make_current() which uses the window's graphics context. Fl_Window::flush() then runs the window's draw() function. 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. Variable through_Fl_X_flush is NO. Under Mac OS 10.4 and higher, the window's graphics context is obtained. Under Mac OS 10.3 a new graphics context adequate for the window is created. Subsequent drawing requests go to this window. 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. */ void Fl_Window::make_current() { if (make_current_counts > 1 && !views_use_CA) return; if (make_current_counts) make_current_counts++; if (views_use_CA && !through_drawRect) { // detect direct calls from the app damage(FL_DAMAGE_CHILD); // make next draws to this window displayed at next event loop } Fl_X::q_release_context(); fl_window = i->xid; Fl_X::set_high_resolution( i->mapped_to_retina() ); current_ = this; //NSLog(@"region-count=%d damage=%u",i->region?i->region->count:0, damage()); #if MAC_OS_X_VERSION_MAX_ALLOWED >= MAC_OS_X_VERSION_10_8 if (views_use_CA) { i->gc = ((FLViewLayer*)[fl_window contentView])->layer_data; # ifdef FLTK_HAVE_CAIRO // make sure the GC starts with an identity transformation matrix as do native Cocoa GC's // because cairo may have changed it CGAffineTransform mat = CGContextGetCTM(i->gc); if (!CGAffineTransformIsIdentity(mat)) { // 10.4 CGContextConcatCTM(i->gc, CGAffineTransformInvert(mat)); } # endif } else #endif { NSGraphicsContext *nsgc; #if MAC_OS_X_VERSION_MAX_ALLOWED >= MAC_OS_X_VERSION_10_4 if (fl_mac_os_version >= 100400) nsgc = [fl_window graphicsContext]; // 10.4 else #endif nsgc = through_Fl_X_flush ?
