This is a first step to fix some background (re-)drawing issues in
widgets. A new bit in the array of boxtypes can be used to determine
if a particular boxtype uses a solid background (e.g. all FL_*_BOX
types) or if the parent widget is responsible for drawing it (FL_NO_BOX
and all FL_*_FRAME) types, and maybe more ...
The old struct member `set` in the struct of boxtypes has been
renamed to `flags` and is now used as a bit field.
Except these changes, this first commit fixes the focus box drawing
of specific boxtypes, as seen in unittest_schemes.cxx in the
Fl_Check_Button with label "Check", and very likely more.
- replace FL_OVERRIDE and NULL with 'override' and 'nullptr', resp.
- remove useless global variable (declare it locally in main)
- standardize callbacks using standard callback signatures
- rename some callbacks with more appropriate names
- fix layout of image display and image size info
- improve alignment of text display
- set window size_range (minimal window size)
Works for all slider types.
Adds tick marks to "nice slider".
Defaults to linear if min or max is zero.
There is room for improvement for drawing the tick marks.
Undiscovered for 10 years, this crude vector font generator
snuck into the font test ten years ago through a careless
commit by yours truly. It's time to go now.
* define the pen/tablet support API
* add pen event handler stub as a fallback
* add pen device test "penpal".
* Add macOS pen/stylus/tablet driver.
* Add Oxygen documentation.
* Change class Fl into namespace Fl.
* Untangle Fl namespace into themed headers.
* cut line count of FL/Fl.H in half
* FL/core subdirectory now holds short headers
grouped by functionality.
In commit a0654b59ac all assignments to
variable `fl_xmousewin` were erroneously put under control of macro
FLTK_CONSOLIDATE_MOTION. This commit reverts this.
The correct fix would have been to declare
extern Fl_Window *fl_xmousewin;
unconditionally which was eventually done in a later commit.
The related variable `static Fl_Window *send_motion;` is still used
under control of macro FLTK_CONSOLIDATE_MOTION.
These Fl_Window methods are 'const' but had not been declared 'const':
- uchar get_size_range(...) const
- int shown() const
- const Fl_Image *shape() const
- int screen_num() const
- fl_uintptr_t os_id() const
