- Add 'int Fl_Terminal::handle_unknown_char(int drow, int dcol)'
to write the "unknown" character to the intended display position.
- Define Fl_Terminal::unknown_char as a static variable to avoid
redundancy. In the future this might be overridden by users.
Some old platforms (NetBSD, AIX) implement the common stdio "putchar()"
function as a global macro which poisons the global namespace, preventing
all C and C++ programs from using "putchar()" as a function or method.
There was a long thread about this in fltk.coredev during the period
Mar 25 2024 ~ Apr 4 2024, subject "RFC: Fl_Terminal::putchar() in public API"
as to why we have no choice but to not use putchar() as a method name.
Some of these accessor methods should be private so they can't be used
by user code but - due to compiler issues - they must be public for
HP-UX 11.11 (for details see GitHub Issue #937).
Works now much better with old C99 and C++98 standard compilers.
Fixed: C++ comments in C files and headers included by C files.
There are still some warnings with C90 though but these would be
hard to fix and left as-is for now.
test/fractals.cxx: some arrays were too small by 1, or the compiler
warned at least (false positive?). Anyway, it's fixed now.
* Improve horizontal interactive selection
* Using half-character positions to implement selection
similar to Fl_Input.
* Add word and line selection
* Fix vertical position of text
Clear was setting characters to a space using the current style,
but if the style left Dim/Bold/Inverse (etc) enabled, that was being
used to affect the clear character, and thus affected clearing screen.
Seems weird tho; what if one wants to do a cleol (\033[K) on a screen
that is all inverted text; is there no way to use inverse mode for
clearing to the end of line? Or to delete a character?
Fixed a bug in the handling of xterm color 39 + 49, which avoids
applying Dim/Bold if default color is the special "see through" color
0xffffff00. A test will be added to test/terminal to excercise this
in a follow up commit.
Renamed CharStyle::?gcolor_uchar() -> CharStyle::?gcolor_xterm()
for a consistent naming convention.
Changed fltk_fg_color() from a static func to a CharStyle method
because it needs to access the defaultcolor for the special cases
for xterm colors 39 and 49.
Made CharStyle::attr_color() private, as per Jonathan Griffitts request
in issue #909.
Improved docs regarding effects of Dim/Bold for xterm and non-xterm color
methods.
Fl_Terminal::text?gcolor_xterm() methods now use CharStyle::?gcolor_xterm()
methods, removing the duplicate code logic.
This is a big commit and there are too many changes to list them all.
The main changes are:
- rename all CMake build options to 'FLTK_*'
- export library targets with namespace (prefix) 'fltk::'
- standardize shared library target names with suffix '-shared'
- set public build properties on libraries for consumers
- document library names and aliases in README.CMake.txt
- document changes in "Migrating Code from FLTK 1.3 to 1.4"
- partial backwards compatibility for old user projects
Included but not directly related changes:
- fix Windows (Visual Studio) DLL build
- add CMake function fl_debug_target() to show target properties
- don't build test programs if FLTK is a subproject
- internal: reformat CMake code: remove space before '('
Thanks to Matthias and Manolo for their help, testing, and feeback.
Fl_Window_Driver::set_popup_window() is to be used to declare a window should be
positioned relatively to a previously mapped other window. This allows a platform
to process such windows differently from other windows if needed.
Menu and tooltip windows are so declared.
A call to Fl_Window_Driver::set_popup_window() also allows to distinguish a real
menu or tooltip window from a window marked by Fl_Window::set_menu_window()
or by Fl_Window::set_tooltip_window() but that's not a real menu or tooltip.
New member function bool Fl_Screen_Driver::screen_boundaries_known() returns
true by default. A platform where the position of windows inside a screen is hidden
(e.g., Wayland) returns false. This allows FLTK to refrain from trying to make sure
a computed position is inside a screen.
This addresses some issues pointed out by GitHub Issue #875.
Documentation lacked details about Fl_Multi_Label assignment and
correct memory handling.
The new methods
- Fl_Menu_Item::image_label(const Fl_Image *) and
- Fl_Menu_Item::multi_label(const Fl_Multi_Label *)
provide a cleaner interface to assign images and Fl_Multi_Label's
to menu items.
examples/howto-menu-with-images.cxx: carify some issues, fix leak,
and use new Fl_Menu_Item::multi_label(const Fl_Multi_Label *).
This library is no longer needed in FLTK itself. There is only one
demo program (test/forms.cxx) that uses it if it is built. The demo
program displays a message if fltk_forms is not available.
The default is 'enabled' for backwards compatibility but this may
be changed to 'disabled' in a future version.
- the current UI for fallback/default/original shortcut was
confusing, so I remove it until we find something better. I
kept the values so we can reinstate a better interface without
changing the API.
- add fl_draw_radio(...) to standardize radio button drawing
- src/Fl_Light_Button.cxx: use fl_contrast() to determine color of
radio button and check (light) button check marks, and use
new fl_draw_radio() method
- src/Fl_Menu.cxx: same as src/Fl_Light_Button.cxx and use
fl_draw_check() instead of "manually" drawing the check mark
(forgotten in an earlier update)
- add Fl::args_to_utf8() to convert commandline arguments to UTF-8
This new function closes the gap that previously only Visual Studio
applications converted their commandlines to UTF-8.
Tested with MinGW, MSYS2/MinGW-w64, and Visual Studio (2019).
