Implement a new way to make the GTK file-chooser window modal-like
by preventing any event processing by other FLTK windows.
The new way is also no longer X11-specific.
Processing of all FLTK events as well as window resizing while the file chooser runs is suspended,
Normal event processing and resizing is restored when chooser closes.
Add new method
Fl_Widget::draw_focus(Fl_Boxtype t, int x, int y, int w, int h, Fl_Color bg)
... with background color for correct contrast testing (in Fl_Tabs)
Draw the focus box of the "tabs" of Fl_Tabs widgets with the correct
boxtype and background color.
Make 'unsigned int visible_focus()' const so it can be used in 'const'
methods.
Do not draw the focus box if the per-widget focus box option is off.
Reading an .fl file rebuilds a menu item arrays with every item read.
If a menu is only partially read, the end marker (label==NULL) is
not set, so that deleting the menu will run beyond the missing marker.
This bug was exposed by adding images to menu items, which
requires additional deletes.
FLTK 1.3 supports complex text input methods (TIMs) for the 3 platforms
(X11, Windows, macOS). This support has an interface with FLTK that is
common for X11 and Windows, via (undocumented) functions fl_set_spot(),
fl_set_status() and fl_reset_spot().
In contrast, and because it's been developed independently, the
interface between the macOS TIM and FLTK 1.3 is completely different :
static functions FL::insertion_point_location() and Fl::reset_marked_text().
The present change implements a single TIM/FLTK interface
used by all platforms based on functions fl_set_spot() and
fl_reset_spot().
The previous macOS-specific functions FL::insertion_point_location() and
Fl::reset_marked_text() are maintained only for compatibility with 1.3
and deprecated.
If a user project is built using a FLTK library generated by CMake
with Cairo support then the CMake variable FLTK_INCLUDE_DIRECTORIES
now includes the required Cairo include directories.
... as discussed in fltk.coredev in thread "RFC: introduce public
config header <FL/fl_config.h>", see:
https://groups.google.com/g/fltkcoredev/c/xLCs1AIXMVo/m/MHZpQggzAQAJ
- Rename abi-version.h to fl_config.h, rename input files,
update dependencies, .gitignore, CMake, configure and Makefiles.
- Include Cairo options in FL/fl_config.h
- Rename FLTK_USE_CAIRO to FLTK_HAVE_CAIROEXT for consistency.
- Include <FL/fl_config.h> in config.h and wherever necessary,
fix include order (move FL/Fl.H to the top) and more.
- Move USE_X11 to fl_config.h and rename to FLTK_USE_X11
- Do not include <config.h> in Cairo demo program which is no
longer required in Cairo programs since FLTK 1.4.0
In Fluid, selecting a menu button, and selecting it again to make it
movable would also grab the text input focus, which would prevent
the enclosing window from using arrow key events to manipulate
the selected widget.
Code now convinces browser to rebuild when the tree changes by UI.
When widgets are move, the current widget should always be visible.
It's the responsibility of the UI callback to update the browser.
