2023-10-16Improve subclassing cababilities of Fl_Tile (STR 2791)Albrecht Schlosser
- remove static variables and functions - make move_intersection() virtual - add (protected) cursor access methods These changes were inspired by STR 2791 where the user proposing an enhancement was not able to subclass Fl_Tile properly. This commit fixes the mentioned issues and enables subclassing without copying internal code.

2023-10-07Fix STR 3458: "GLUT compatibility mode segfaults"Albrecht Schlosser
... "when there's no current window". Silently ignore GLUT function calls that need a current window if the current window is NULL, return 0 from functions that return an 'int'. Check if window is shown in Fl_X11_Gl_Window_Driver::swap_buffers(). This would issue "XRequest.nnn: GLXBadDrawable 0x0" on X11 otherwise. Note: the chosen implementation to ignore GLUT calls silently appears to be compatible with GLUT (3.7) whereas FreeGLUT 3.0 would issue error messages and exit. The latter could be implemented as well but would be much more work.

2023-09-26FLUID: adds greatly enhanced Shell Commands (#774)Matthias Melcher
The user can add an arbitrary number of highly configurable shell commands through the setting panel. The commands can be saved as user preferences, inside the .fl file, or exported to an external file. Shell scripts can be limited to individual platforms, can have shortcut keys, etc. . * documentation will follow * support to call `fltk-config` will follow

Wrote wrong path in #inlude statement under certain conditions. Also removed 'snap' tag if not needed.
2023-09-22Fix potential invalid stack variable access in test codeAlbrecht Schlosser
This code was (and is still) commented out but it *would* trigger a "stack buffer overflow" error *if* uncommented. The new code demonstrates how a binary object (Fl_Preferences 'bed') can be dumped to a preferences file in binary format (if activated).

2023-09-12Fix Visual Studio shared library buildAlbrecht Schlosser
Todo: fluid-shared can't (yet) be built agains the shared fltk lib because of some linker errors. Needs investigation. Note: fluid-shared is basically a test program to demonstrate linking against the shared FLTK libs but doesn't work yet using VS (MSVC). This is no problem for the functionality.

2023-07-12Display mouse button state in test/handle_events.cxx demoAlbrecht Schlosser
See fltk.general, thread "Is handling simultaneous Left-click and Right-click drags supported?" from Jul 12, 2023 Status: FL_DRAG operation is terminated when one mouse button is released, even if more than one button is actually down. Subsequent mouse movement is reported as FL_MOVE rather than FL_DRAG, this is under investigation.

2023-03-14Cairo: introduce Fl::cairo_flush() in FLTK APIAlbrecht Schlosser
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)
2023-03-12Simplify the previous Cairo drawing fix (#694)Albrecht Schlosser
The Cairo context 'cc' should be used directly rather than calling 'Fl::cairo_cc()' again. Sorry for the noise.
2023-03-12Fix Cairo drawing in test/cairo_test demo for Windows (#694)Albrecht Schlosser
On the Windows platform Cairo drawings must be flushed explicitly. This is done in Fl_Cairo_Window after calling the draw callback but it was neither done nor documented in test/cairo_test.cxx when using another type of Window with its overloaded draw() method, i.e. when FLTK was configured with --enable-cairoext or CMake OPTION_CAIROEXT. Note: user code must either explicitly flush the Cairo drawings as done here or destroy the Cairo context which is not done in this demo because the Cairo context should be kept alive.
2023-03-09Fix dependencies, typos, trailing whitespace, and formattingAlbrecht Schlosser
No code changes.
2023-03-09CMake: build shared libs with OPTION_CAIROEXT (issue #250)Albrecht Schlosser
- 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.
