* interactive layout alignment rewritten
* interface for new alignment rules
* new alignment dialog box
* user defined layout rules added
* layout rules can be stored in projects, settings, and external files
* Valgrind verification
Flushing the Cairo context is necessary on Windows to make Cairo
drawings appear on the device (screen). This new method makes it easy
for user code to do this correctly after using Cairo drawings.
- add Fl::cairo_flush(cairo_t *)
- document Fl::cairo_flush(cairo_t *)
- reformat Cairo doxygen docs and code (partially)
- use the new method in Fl_Cairo_Window
- use the new method in test/cairo_test.cxx
- other minor (text) changes in test/cairo_test.cxx
- add test/cairo_test to the demo menu (test/demo.menu)
- remove separate libfltk_cairo to avoid cyclic dependencies, but
- keep a dummy libfltk_cairo in 1.4.0 for backwards compatibility
- move cairo/Fl_Cairo.cxx to src/Fl_Cairo.cxx
- add preliminary Cairo support for Visual Studio (MSVC)
Static linking is not affected by this change, but users building
with hand-made Makefiles will have to remove libfltk_cairo starting
with FLTK 1.4.0. The dummy library can be linked for backwards
compatibility but it will be removed later (in 1.4.x or 1.5.0).
The shared FLTK library libfltk.{so|dylib|dll|..} depends on libcairo
if and only if FLTK is built with one of the Cairo options. This has
always been the case for OPTION_CAIROEXT but is now also true if only
OPTION_CAIRO is selected, i.e. FLTK programs linked with a Cairo
enabled shared FLTK library will also be linked with libcairo. The same
is true for configure options --enable-cairo and --enable-cairoext,
respectively.
Preliminary Cairo support for MSVC now detects a Cairo installation
using the CMake variable FLTK_CAIRO_DIR which must be set by the user.
Note that this feature is temporary and may be changed in the future
for a better and more comfortable version.
- add true unittest and Fl_String testing
- interface and printout are similar to gtest
without requiring external linkage.
just run `unittest --core`.
- new Fl_String API
- extended API to fl_input_str and fl_password_str
- co-authored-by: Albrecht Schlosser <albrechts.fltk@online.de>
Also
- fix "\todo Unicode?" in Fl_Text_Display::display_insert() after verification
- fix "\todo [Internal] The user_data value must be implemented using \p fl_intptr_t"
because that's now in place.
This commit makes the local, static drawing functions in the source
file available for subclasses by converting them to static protected
methods as requested by STR 2022.
The source and header files have been reformatted according to the
CMP, documentation for the new protected methods was added.
Source code *functionality* has not been changed.
This resolves and closes STR 2022.
Todo:
- investigate whether these drawing methods wouldn't better be
member functions and "convert" them if applicable
- investigate whether the internal struct FL_CHART_ENTRY could become
a local part of the Fl_Chart class, maybe Fl_Chart::Entry.
- rename private member variables with trailing underscore (see CMP)
This widget offers the selection of all known FLTK schemes as a simple
widget based on Fl_Choice.
Some test and demo programs use Fl_Scheme_Choice to enable the developer
or user to switch schemes quickly for comparison.
Todo:
- add features to add new schemes during runtime (partially done)
- update status when the scheme is changed by Fl::scheme("...")
