* macosx/tkMacOSXCarbonEvents.c: add window event target carbon event
* macosx/tkMacOSXEvent.c: handler for all kEventClassWindow and * macosx/tkMacOSXEvent.h: kEventClassMouse events; * macosx/tkMacOSXNotify.c: move all remaining events except for * macosx/tkMacOSXWindowEvent.c: kEventClassKeyboard from dispatcher to application event handler; pass event handler callRef downstream; fix debug event tracing; process all tcl event types in carbon event timer; delay carbon event timer first fire; add TkMacOSXTrackingLoop() to mark enter/exit of event tracking loop during which all tcl events but only carbon update events should be processed by the timer (replaces various calls to Tcl_SetServiceMode()); rename TkMacOSXReceiveAndProcessEvent() to TkMacOSXReceiveAndDispatchEvent(), move it from tkMacOSXEvent.c to tkMacOSXCarbonEvents.c and modify it to dequeue only update events during a tracking loop; add TkMacOSXRunTclEventLoop() to standardize the various ways in use to run the tcl event loop; add handling of kEventClassAppearance events (for ScrollBarVariantChanged event). * macosx/tkMacOSXDialog.c: use new TkMacOSXTrackingLoop() around * macosx/tkMacOSXEvent.c: blocking API that puts up modal dialogs * macosx/tkMacOSXMenu.c: or when entering/exiting menu/control * macosx/tkMacOSXMouseEvent.c: tracking, window dragging and other * macosx/tkMacOSXScale.c: mouse tracking loops. * macosx/tkMacOSXScrlbr.c: * macosx/tkMacOSXWindowEvent.c: * macosx/tkMacOSXWm.c: * macosx/tkMacOSXDialog.c: use new TkMacOSXRunTclEventLoop() * macosx/tkMacOSXScale.c: instead of Tcl_DoOneEvent(), * macosx/tkMacOSXScrlbr.c: Tcl_ServiceAll(), TclServiceIdle() * macosx/tkMacOSXWindowEvent.c: and Tcl_GlobalEval("update idletasks"). * macosx/tkMacOSXColor.c: make available as Tk system colors all * macosx/tkMacOSXPort.h: appearance manager brushes, text colors and backgrounds with new and legacy names, as well as the fully transparent color "systemTransparent"; add TkMacOSXSetColorIn{Port,Context}() to directly set an X pixel color value in the current QD port resp. the given CG context without requiring passage through rgb representation (lossy for most system colors); modernize/remove Classic-era code; replace crufty strcmp() elseifs by Tcl_GetIndexFromObjStruct(). * macosx/tkMacOSXButton.c: use new TkMacOSXSetColorInPort() * macosx/tkMacOSXDraw.c: instead of setting rgb color directly * macosx/tkMacOSXMenubutton.c: to allow for non-rgb system colors. * macosx/tkMacOSXCursor.c: implement "none" cursor as on other platforms [Patch 1615427]; add all missing appearance manager cursors. * macosx/tkMacOSXDefault.h: set SELECT_FG_COLORs to None to match aqua L&F; use standard system color names; use new 'menu' system font; correct default scrollbar width. * macosx/tkMacOSXDraw.c: standardize initialization, use and * macosx/tkMacOSXInt.h: emptying of various static temp rgns * macosx/tkMacOSXRegion.c: onto two global RgnHandles; in debug * macosx/tkMacOSXSubwindows.c: builds, verify emptiness of these temp * macosx/tkMacOSXWindowEvent.c: rgns before use. * macosx/tkMacOSXDraw.c: add TkMacOSX{Setup,Restore}DrawingContext() to * macosx/tkMacOSXInt.h: abstract common setup & teardown of drawing environment (for both CG and QD); save/restore QD theme drawing state; handle GC clip region; add TkpClipDrawableToRect() to allow clipped drawing into drawable regardless of GC used; use new system color "systemWindowHeaderBackground" to setup background in themed toplevels; correct implementation of TkMacOSXMakeStippleMap(). * macosx/tkMacOSXEntry.c: use new TkMacOSXSetupDrawingContext() and * macosx/tkMacOSXFont.c: TkMacOSXRestoreDrawingContext() instead of * macosx/ttkMacOSXTheme.c: various setup/teardown procs like TkMacOSX{SetUp,Release}CGContext(), TkMacOSXQuarz{Start,End}Draw(), TkMacOSXSetUpGraphicsPort() etc. * macosx/tkMacOSXEmbed.c: add CG context and drawable clip rgn fields * macosx/tkMacOSXInt.h: to MacDrawable struct. * macosx/tkMacOSXSubwindows.c: * macosx/tkMacOSXDialog.c: make -parent option of tk_getOpenFile et al. use the sheet version of NavServices dialogs; ensure native parent win exists before using StandardSheet API for tk_messageBox [Bug 1677611]; force sheets to behave like app-modal dialogs via WindowModality() API; use more modern ColorPicker API. * macosx/tkAboutDlg.r: use themed movable modal dialog, fix (c) year. * macosx/tkMacOSXEntry.c: take xOff/yOff of MacDrawable into account * macosx/ttkMacOSXTheme.c: when computing locations/bounds to ensure correct posititioning when not drawing into intermediate pixmap. * macosx/tkMacOSXFont.c: use appearance manager API to map system font * macosx/tkMacOSXFont.h: names to TkFonts; add "menu" system font for menu item text drawing from MDEF; always draw with CG; remove QD dependent stippling algorithm; move most header declarations into the source file (as they were not used anywhere else). * macosx/tkMacOSXMenu.c: large-scale rewrite of custom * macosx/tkMacOSXMenu.r (removed): MDEF and related code that * macosx/Wish.xcode/project.pbxproj: restores many longtime-MIA * macosx/Wish.xcodeproj/project.pbxproj: features to working order * unix/Makefile.in: (e.g. images, custom colors & fonts in menus etc); implement compound menu items; use Appearance Mgr and ThemeText APIs to mimic native MDEF as closely as possible when default "menu" system font is used; remove now obsolete SICN drawing code and resources. * macosx/tkMacOSXCarbonEvents.c: handle additional menu carbon events * macosx/tkMacOSXEvent.c: in order to support <<MenuSelect>> in * macosx/tkMacOSXMenu.c: the menubar and in menus that are not * macosx/tkMacOSXMenus.c: using the custom MDEF [Bug 1620826]; fix early and missing clearing of current Tk active menu entry; fix extraneous sending of <<MenuSelect>> during active menu entry clearing. * macosx/tkMacOSXMouseEvent.c: add support for async window dragging by the window server; set the corresponding window attribute by default. * macosx/tkMacOSXMouseEvent.c: rationalized handling order of non-mousedown events; add TkMacOSXModifierState() to retrieve the current key modifiers in carbon format. * macosx/tkMacOSXScrlbr.c: use appearance manager API to retrieve scrollbar component metrics; add awareness of multiple possibilites for scrollbar arrow position in aqua and handle user changes to arrow position pref; handle difference in metrics of small & large scrollbar variants; handle aqua "jump to here" scrollbar behaviour; correct computation of scroll view size and position; enforce min scrollbar height to avoid scrollbar component overlap; erase scrollbar area outside of standard width; remove broken auto-adjust code; account for window class when leaving space for grow box; remove code to manually draw grow box; use modern API for thumb scroll proc; replace HiliteControl() by modern API; replace control mgr constants with appearance mgr equivalents. * macosx/tkMacOSXSubwindows.c: use SetWindowBounds() API instead of SizeWindow(); invalidate clip regions after X{Map,Unmap}Window as fix for [Bug 940117] made them dependent on mapping state; remove unneeded calls to TkMacOSXInvalClipRgns() and unnecessary setting of QD port; use native-endian pixmap on intel; remove obsolete pixmap pix locking. * macosx/tkMacOSXWindowEvent.c: handle only the first of a batch of kEventAppAvailableWindowBoundsChanged events sent per transaction; handle kEventWindowBoundsChanged event to support live window resizing and centralized sending of location/size changed ConfigureNotify events; ensure HIGrowBox is redrawn after bounds change; constrain window after dragging to ensure titlebar is not inacessible offscreen or under dock/menubar; handle kEventWindowGetRegion and kEventWindowDrawContent for transparent windows to mark resp. paint content region as transparent; handle kEventWindowConstrain for fullscreen windows to ensure bounds match new screen size; enter/exit fullscreen UIMode upon activation/deactivation of fullscreen window. * macosx/tkMacOSXWm.c: use live-resize and async-drag carbon window * macosx/tkMacOSXWm.h: attributes for toplevels by default; implement new [wm attributes] -topmost, -transparent and -fullscreen; refactor WmAttributesCmd() parallelling the tkUnixWm.c implementation, use thus factored proc to set proxy icon from [wm iconbitmap]; dynamically determine default values for toplevel min and max sizes (similar to tkWinWm.c impl): min sizes depend on window class & attributes to ensure visibility of all titlebar widgets and grow box, max sizes depend on maximal window bounds for all active displays; factor out code that puts into effect changes to master or override_redirect; use RepositionWindow() API to determine staggered initial window bounds; correct resize limit calculations, handle gridding and use modern resize API in TkMacOSXGrowToplevel(); remove sending of ConfigureNotify after resize or zoom (now handled by BoundsChanged handler); correct composite carbon window attribute handling, remove currently unusable attributes and add new attributes in [tk::unsupported::MacWindowStyle]; ensure validity of window class and attributes before use; apply changes to window class when handling carbon window attribute changes (if HIWindowChangeClass() API available); add debug build warning message when deprecated window style is used instead of window class; use transparent HIGrowBox for resizable windows; avoid unnecessary calls to window structure width API; use tcl time API in TkpGetMS(); add TkMacOSXEnterExitFullscreen() to enter/exit UIMode with dock and menubar hidden; restrict wmTracing output to debug builds; remove unneeded calls to TkMacOSXInvalClipRgns() and unnecessary setting of QD port; workaround GetWindowStructureWidths() Carbon bug (bogus results for never-mapped floating windows). * macosx/tkMacOSXXStubs.c (TkMacOSXDisplayChanged): add maximal window bounds field to Screen record (in ext_data), computed as the union of available window positioning bounds of all graphics devices (displays). * macosx/tkMacOSXBitmap.c: fix macRoman encoding leak. * macosx/tkMacOSXCursor.c: * macosx/tkMacOSXDebug.c (TkMacOSXCarbonEventToAscii): use static * macosx/tkMacOSXDebug.h: buffer to simplify callers; const fixes. * macosx/tkMacOSXBitmap.c: use more efficient QDSwapPort() instead of * macosx/tkMacOSXButton.c: GetPort()/SetPort()/GetGWorld()/SetGWorld(). * macosx/tkMacOSXDraw.c: * macosx/tkMacOSXMenubutton.c: * macosx/tkMacOSXScale.c: * macosx/tkMacOSXScrlbr.c: * macosx/tkMacOSXXStubs.c: * macosx/tkMacOSXColor.c: use kHIToolboxVersionNumber for runtime OS * macosx/tkMacOSXEntry.c: version check rather than Gestalt() etc. * macosx/tkMacOSXInt.h: * macosx/tkMacOSXWm.c: * macosx/tkMacOSXDraw.c: remove obsolete and now incorrect * macosx/tkMacOSXInt.h: tkMenuCascadeRgn clipping code. * macosx/tkMacOSXMenu.c: * macosx/tkMacOSXHLEvents.c: replace Tcl_GlobalEval() resp. Tcl_Eval() * macosx/tkMacOSXScrlbr.c: by Tcl_EvalEx(). * macosx/tkMacOSXInit.c: * macosx/tkMacOSXInit.c (TkpInit): reorder initialization steps. * macosx/tkMacOSXKeyEvent.c: remove pre-10.2 support. * macosx/tkMacOSXMenus.c: remove now useless call to TkMacOSXHandleTearoffMenu(); use \x.. quoting for non-latin1 macroman literar chars to allow file to be edited as utf-8. * macosx/tkMacOSXScale.c: replace TrackControl() by modern * macosx/tkMacOSXScrlbr.c: HandleControlClick() API (using new TkMacOSXModifierState()). * macosx/tkMacOSXInt.h: move all constant #defines needed to * macosx/tkMacOSXColor.c: support building on older OS X releases * macosx/tkMacOSXEvent.h: to a central location in tkMacOSXInt.h. * macosx/tkMacOSXFont.c: * macosx/tkMacOSXMenu.c: * macosx/tkMacOSXMenubutton.c: * macosx/tkMacOSXMenus.c: * macosx/tkMacOSXMouseEvent.c: * macosx/tkMacOSXWm.c: * macosx/ttkMacOSXTheme.c: * macosx/tkMacOSXInt.h: add ChkErr() macro to factor out * macosx/tkMacOSXButton.c: Carbon OSStatus return value checking * macosx/tkMacOSXCarbonEvents.c: and TkMacOSXDbgMsg() macro to factour * macosx/tkMacOSXClipboard.c: out debug message output; use these * macosx/tkMacOSXColor.c: macros to replace #ifdef TK_MAC_DEBUG * macosx/tkMacOSXCursor.c: blocks & direct printing to stderr, * macosx/tkMacOSXDebug.c: and to do additional OSStatus return * macosx/tkMacOSXDialog.c: checking, and to standardize OSStatus * macosx/tkMacOSXDraw.c: usage. * macosx/tkMacOSXEntry.c: * macosx/tkMacOSXEvent.c: * macosx/tkMacOSXFont.c: * macosx/tkMacOSXHLEvents.c: * macosx/tkMacOSXInit.c: * macosx/tkMacOSXKeyEvent.c: * macosx/tkMacOSXMenu.c: * macosx/tkMacOSXMenubutton.c: * macosx/tkMacOSXMenus.c: * macosx/tkMacOSXMouseEvent.c: * macosx/tkMacOSXScrlbr.c: * macosx/tkMacOSXSubwindows.c: * macosx/tkMacOSXWindowEvent.c: * macosx/tkMacOSXWm.c: * macosx/tkMacOSXXStubs.c: * macosx/tkMacOSXSend.c: remove duplicate/unused declarations * macosx/tkMacOSXXStubs.c: * macosx/tkMacOSXDebug.c: const fixes. * macosx/tkMacOSXInit.c: * macosx/tkMacOSXTest.c: * macosx/tkMacOSXWm.c: * macosx/tkMacOSXXStubs.c: * macosx/Wish-Info.plist.in: add tcl document extensions/mime types and LSMinimumSystemVersion, LSRequiresCarbon & NSAppleScriptEnabled keys. * macosx/Wish-Common.xcconfig: add Wish's Info.plist as __info_plist section to tktest; enable more warnings. * macosx/Wish.xcodeproj/project.pbxproj: add 'DebugMemCompile' build configuration that calls configure with --enable-symbols=all; disable configure check for __attribute__((__visibility__("hidden"))) in Debug configuration to restore availability of ZeroLink. * macosx/Wish-Common.xcconfig: fix whitespace. * macosx/Wish-Debug.xcconfig: * macosx/Wish-Release.xcconfig: * macosx/tkMacOSXAETE.r: * macosx/tkMacOSXConfig.c: * macosx/tkMacOSXCursors.r: * macosx/tkMacOSXKeyboard.c: * macosx/tkMacOSXSend.c: * macosx/ttkMacOSXTheme.c: * macosx/tkMacOSXXCursors.r: * macosx/README: * macosx/GNUmakefile: fix/add copyright and license refs. * macosx/Tk-Info.plist.in: * macosx/Wish-Info.plist.in: * macosx/Wish.xcode/project.pbxproj: * macosx/Wish.xcodeproj/project.pbxproj: * macosx/tkMacOSX.h:
