These were introduced at r12647, that is, during development of the 1.4 API. These functions provided windowless support only on the MacOS platform, where this can be obtained without those functions. Windowless support on other platforms would require changing the event loop. There's no evidence from STR's there's a demand for windowless mode on other platforms. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12680 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

Changes in FLTK 1.4.0 Released: ??? ?? 2017
|
|
|
|
General Information about this Release
|
|
|
|
- FLTK 1.4.0 is based on FLTK 1.3.4 (released Nov 15 2016),
|
|
see CHANGES_1.3 for more information.
|
|
|
|
- CMake is the primary supported build system in FLTK 1.4.0 and later.
|
|
CMake can be used to generate Makefiles, IDE project files, and
|
|
several other build systems by using different "generators" provided
|
|
by CMake (for instance Ninja, CodeBlocks, Eclipse, KDevelop3, Xcode, etc.).
|
|
See README.CMake.txt for more information.
|
|
|
|
- autoconf/configure is still supported by the FLTK team for backwards
|
|
compatibility with older systems that lack CMake support.
|
|
|
|
|
|
New Features and Extensions
|
|
|
|
- (add new items here)
|
|
- OpenGL draws text using textures on all platforms, when the necessary
|
|
hardware support is present (a backup mechanism is available in absence
|
|
of this support). Thus, all text drawable in Fl_Window's can be drawn
|
|
in Fl_GL_Window's (STR#3450).
|
|
- New member functions Fl::program_should_quit(void),
|
|
and Fl::program_should_quit(int) to support detection by the library
|
|
of a request to terminate cleanly the program.
|
|
- MacOS platform: the processing of the application menu's "Quit" item
|
|
has been changed. With FLTK 1.3.x, the application terminated when all
|
|
windows were closed even before Fl::run() of Fl::wait() could return.
|
|
With FLTK 1.4, Fl::run() returns so the app follows its normal termination path.
|
|
- MacOS platform: Added support for rescaling the GUI of any app at run-time
|
|
using the command/+/-/0/ keystrokes.
|
|
- MSWindows platform: Added optional support for rescaling the GUI of any app
|
|
at run-time using the ctrl/+/-/0/ keystrokes. This requires to build the
|
|
FLTK library with -DFLTK_HIDPI_SUPPORT (for now). This option also makes
|
|
app detect the desktop scaling factor and automatically scale their GUI
|
|
accordingly. This effectively renders WIN32 FLTK apps "per-monitor DPI-aware"
|
|
whereas they were "DPI-unaware" with FLTK 1.3.4.
|
|
- FLTK apps on the MacOS platform contain automatically a Window menu, which,
|
|
under MacOS ≥ 10.12, allows to group/ungroup windows in tabbed form. The new
|
|
Fl_Sys_Menu_Bar::window_menu_style() function allows to specify various
|
|
styles for the Window menu, even not to create it.
|
|
- New function: int fl_open_ext(const char* fname, int binary, int oflags, ...)
|
|
to control the opening of files in binary/text mode in a cross-platform way.
|
|
- New Fl_SVG_Image class: gives support of scalable vector graphics images
|
|
to FLTK using the nanosvg software.
|
|
- Fl_Text_Selection got a new method length() and returns 0 in length()
|
|
and in all offsets (start(), end(), position()) if no text is selected
|
|
(selected() == false). The behavior in FLTK 1.3 and earlier versions
|
|
(returning undefined values if !selected()) was confusing.
|
|
- Added support for MacOS 10.13 "High Sierra".
|
|
- New method Fl_Group::bounds() replaces Fl_Group::sizes() which is now
|
|
deprecated. Fl_Group::bounds() uses the new class Fl_Rect that contains
|
|
widget coordinates and sizes x(), y(), w(), and h() (STR #3385).
|
|
Documentation for bounds() and its internal structure was added.
|
|
- X11 platform: Added support for HiDPI displays and for rescaling any window
|
|
at run-time under user control. Under the gnome desktop, FLTK applications
|
|
detect the current gnome scaling factor and use it to scale all FLTK windows.
|
|
Under other desktops, the FLTK_SCALING_FACTOR environment variable can be
|
|
used to set the starting scaling factor of all FLTK applications.
|
|
In addition, it is possible to rescale all FLTK windows mapped to a screen
|
|
by typing ctrl-'+' (enlarge), ctrl-'-' (shrink) or ctrl-'0' (back to starting
|
|
factor value). Windows moved between screens adjust to the scaling factor of
|
|
their screen. This supports desktops mixing screens with distinct resolutions.
|
|
[HiDPI displays have been supported since FLTK 1.3.3 for the WIN32 and MacOS platforms].
|
|
- New method shadow(int) allows to disable the shadows of the hands
|
|
of Fl_Clock, Fl_Clock_Output, and derived widgets.
|
|
- New method Fl_Tabs::tab_align() allows to set alignment of tab labels,
|
|
particularly to support icons on tab labels (STR #3076).
|
|
- Added '--enable-print' option to configure effective under X11 platforms
|
|
and with 'yes' default value. Using '--enable-print=no' removes print
|
|
and PostScript support from the FLTK library, thus reducing its size.
|
|
- Added Fl_Surface_Device::push_current(new_surface) and
|
|
Fl_Surface_Device::pop_current() to set/unset the current surface
|
|
receiving graphics commands.
|
|
- X11 platform: Added support for drawing text with the pango library
|
|
which allows to draw most scripts supported by Unicode, including CJK
|
|
and right-to-left scripts. The corresponding CMake option is
|
|
OPTION_USE_PANGO. The corresponding configure option is --enable-pango.
|
|
This option is OFF by default.
|
|
|
|
New Configuration Options (ABI Version)
|
|
|
|
- The library can be built without support for SVG images using the
|
|
--disable-nanosvg configure option or turning off OPTION_USE_NANOSVG in CMake.
|
|
- FLTK's ABI version can be configured with 'configure' and CMake.
|
|
See documentation in README.abi-version.txt.
|
|
|
|
|
|
1.4.0 ABI FEATURES
|
|
|
|
- None. FLTK 1.4.0 has a new ABI, breaking 1.3.x ABI.
|
|
|
|
|
|
Other Improvements
|
|
|
|
- (add new items here)
|
|
- The include file for platform specific functions and definitions
|
|
(FL/x.H) has been replaced with FL/platform.H. FL/x.H is deprecated
|
|
but still available for backwards compatibility (STR #3435).
|
|
FL/x.H will be removed in a (not yet specified) future FLTK release.
|
|
We recommend to change your #include statements accordingly.
|
|
- The Fl_Boxtype and Fl_Labeltype definitions contained enum values
|
|
(names) with a leading underscore (e.g. _FL_MULTI_LABEL) that had to
|
|
be used in this form. Now all boxtypes and labeltypes can and should
|
|
be used without the leading underscore. A note was added to the enum
|
|
documentations to make clear that the leading underscore must not be
|
|
used in user code, although the enum documentation still contains
|
|
leading underscores for technical reasons (internal use).
|
|
- The blocks demo program got a new keyboard shortcut (ALT+SHIFT+H) to
|
|
reset the user's high score. It is now slower than before in higher
|
|
levels, hence you can expect higher scores (due to a bug fix in the
|
|
timer code). You can use the '+' key to increase the level at all times.
|
|
- Some methods of Fl_Tabs are now virtual and/or protected for easier
|
|
subclassing without code duplication (STR #3211 and others).
|
|
To be continued...
|
|
- Separated Fl_Input_Choice.H and Fl_Input_Choice.cxx (STR #2750, #2752).
|
|
- Separated Fl_Spinner.H and Fl_Spinner.cxx (STR #2776).
|
|
- New method Fl_Spinner::wrap(int) allows to set wrap mode at bounds if
|
|
value is changed by pressing or holding one of the buttons (STR #3365).
|
|
- Fl_Spinner now handles Up and Down keys when the input field has
|
|
keyboard focus (STR #2989).
|
|
- Renamed test/help.cxx demo program to test/help_dialog.cxx to avoid
|
|
name conflict with CMake's auto-generated target 'help'.
|
|
- Many documentation fixes, clarifications, and enhancements.
|
|
|
|
|
|
Bug Fixes
|
|
|
|
- (add new items here)
|
|
- Fix Fl_PNG_Image error handling. An error was potentially caused
|
|
by error handling of the image library with setjmp/longjmp.
|
|
- Fix Fl_Browser background and text color parsing (STR #3376).
|
|
- Fix Windows CreateDC/DeleteDC mismatch (STR #3373).
|
|
- Fix Fl_Tabs label drawing for Fl_Window children (STR #3075).
|
|
- Fix line number alignment in Fl_Text_Display/Editor (STR #3363).
|
|
- Fix ignored buffer pre-allocation (requestedSize) in Fl_Text_Buffer.
|
|
See fltk.general "Fl_Text_Buffer constructor bug" on Dec 5, 2016.
|
|
- Fix build with configure --enable-cairo --enable-cairoext,
|
|

|
|
removed. Please use CMake to generate your IDE project files.
