Clarify functionality of fl_not_clipped() and fl_clip_box().
Add developer documentation for Fl_Graphics_Driver::clip_box().
Documentation only, no code changes in this commit.
The demo exhibits a sometimes annoying /feature/ to spin the entire
puzzle if a user happens to click and/or drag the mouse somewhere on
the puzzle's background rather than on a puzzle piece.
A new command line option '-n' disables this feature entirely.
The extended menu and keyboard commands learned a new option and
keyboard shortcut 'n' => "Normal Position" to stop spinning and
to reset the puzzle to its original position.
The space key is another (hidden) shortcut for 'n'.
See report in fltk.coredev as of today (Jan 16, 2020):
"Fl_Input in readonly mode - wrong behaviour".
Summary: Drag and drop within a read-only Fl_Input (i.e. Fl_Output)
widget would not insert the dragged text (correct) but removed
the dragged text from the widget (error). This is now fixed.
The main fixes are only to avoid static code analyzer warnings reported
in issue #5, but there are also minor bug fixes included. These bug
fixes are more of theoretical concerns though.
Close#6.
This new class is explicitly internal and undocumented. We can
rename and/or redefine or extend it as we need.
This work is based on Matt's recent update with separate internal
classes BMPReader and GIFReader which have been replaced by
Fl_Image_Reader.
Detailed information on how preference file paths are generated, and preliminary docs what happens if that fails. Documentation, on what FLTK die pre 1.4 when any of this failed. Also, a little TODO list for me that I will hopefully get to in the next days.
Text outside the 16-bit X11 coordinate space must be clipped before
calling X11 draw functions, otherwise text might appear anywhere
in the window because X11 would "truncate" the coordinates instead
of proper clipping (X11 handles only 16-bit coordinates).
The FLTK 1.0 compatibility support by defining macro 'FLTK_1_0_COMPAT'
did no longer work since FLTK 1.3.x and nobody complained. Hence we
can safely remove this "feature".
Documentation changes:
- Drop chapter 'Migrating Code from FLTK 1.0 to 1.1'
- Drop chapter 'Migrating Code from FLTK 1.1 to 1.3'
- Add chapter 'Migrating Code from FLTK 1.3 to 1.4'
The removed chapters are still available in FLTK 1.3 docs.
Added Fl_Preferences::file_access() and various flags that make it possible to limit or completely deny file access to the preferences system, either for the core library or for the application or both.
