Documentation only: users must load a font with fl_font(face, size)
before measuring text with methods like fl_measure(), fl_height(),
fl_width(), fl_text_extents() etc.
This method can be used to set a more appropriate color average to
prevent "graying out" the box colors of the 'plastic' scheme.
Alternatively environment variable 'FLTK_PLASTIC_AVERAGE' can be used
to set the color average value. See docs for details.
Set color average to 45% in test/unittests demo program.
By defining boxtypes with underscores, box
drawing cod ethat was not used was not linked,
but with the introduction of themes, all boxes
are available at all times. Reducing complexity.
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.
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.
* 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.
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
FL/Fl_Table_Row.H: use `std::vector<uint8_t> _rowselect;`,
remove declaration of class `CharVector`
src/Fl_Table_Row.cxx: remove implementation of class `CharVector`,
simplify loops (use range based for loops),
use resize() to change vector size.
Unify copyright year of Fl_Table* headers and implementation.
- using a Pointer to Implementation instead of having
a huge Fl_Help_View class. This improves build speed
(smaller header fiel) and allows us to fix the
implementation while keeping the ABI unchanged.
