Some functions didn't document the handling of arguments properly,
particularly Fl::has_timeout() and Fl::remove_timeout().
This is now fixed by documenting the correct behavior that was
preserved (re-implemented) from FLTK 1.3.x in the new class Fl_Timeout.
Unfortunately there have been some inconsistencies (likely unexpected
behavior) which have been preserved and which are now documented.
The d-n-d target window is now always the top-level window even if the
mouse is over a subwindow. That's what all other platforms do.
Global var fl_dnd_target_surface memorise what's the current d-n-d target
surface and follows changes from top-window to subwindows.
Drag-n-drop under Wayland was OK in general except when the drop target is an Fl_Window
because the belowmouse object is not set in this configuration.
Processing an FL_ENTER event before the FL_DND_RELEASE event fixes that.
This issue is caused by setting `Fl_Group::current(0);` in
Fl_Window::show(), i.e. in Fl_X::make_xid(..) in an attempt to
fix a "very common user bug: forgot end()". As long as this is
done, this commit fixes the issue.
For details see GitHub issue #515.
These option combinations work:
-DOPTION_APPLE_X11
-DOPTION_APPLE_X11 -DOPTION_USE_CAIRO
But
-DOPTION_APPLE_X11 -DOPTION_USE_PANGO
is not possible because homebrew doesn't provide the pangoxft package.
This file is now compatible up to Doxygen 1.9.5, i.e. there are
no warnings about obsolete parameters when generating the docs.
Current git 'master' of Doxygen (1.9.6: not yet released) issues
some warnings but these will hopefully be fixed in Doxygen.
Oldest tested Doxygen: 1.8.17 - older versions may emit warnings.
Doxygen uses a <div> with center alignment for images, hence
adding HTML center alignment for image is not only superfluous
but was also inconsistent.
Also removed some more unnecessary HTML tags, updated copyright year.
The code failed with 2 or more widgets when FLTK would trigger
partial redraws of the widgets, unless the Fl_Gl_Window was FL_DAMAGE_ALL.
This commit also adds a second FLTK widget to example/OpenGL3test to
check this multiple widget situation, and fixes an error where operator ! was used
instead of ~ .
This commit fixes " "drawing an fl_pie() with dimension 1x1".
But it does not change "drawing fl_line() with begin position = end position does not show"
because the same behaviour is observed with Windows and macOS.
Ignore error if docs are not generated using a git working tree, for
instance from a downloaded tarball or zip file. This is only a
temporary solution for issue #499 (see "FIXME" comment).
Execute doxygen only if it is available. i.e. found by CMake.
This commit allows to switch between FL_DOUBLE / FL_SINGLE modes
in widget-containing GL3 windows.
Demo program examples/OpenGL3test is modified to show FLTK widgets
even if the platform does not support OpenGL 3.
