(1) Ensure that the terminal widgets doesn't use keyboard events.
Advantage: keyboard navigation and selection doesn't interfere
with the display.
Drawback: Contents of the terminal can no longer be copied.
This will be addressed in a later update.
(2) Thanks to Manolo for his addition of the "GUI scaling" button.
Although GUI scaling can be useful, it can also be annoying while
testing shortcuts.
(3) Changed all light buttons to check buttons.
Esc is intentionally consumed by the test program (see comment) but
other keystrokes (shortcuts) must pass to allow zooming with ctrl/+/-/0.
The old code filtered all shortcuts which turned out to be wrong.
Not being able to zoom was caused by a previous commit that lowered
the priority of the zoom key handler - which alone was not wrong.
The macOS Window menu is connected to the item array of the macOS menubar
via FL_SUBMENU_POINTER. This facilitates memorization of pointers
to items of the macOS menubar because the item array no longer changes
each time a window opens of gets closed.
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.
Keyboard behavior for button types was not consistent with mouse
click behavior. This change avoids callbacks when pressed radio buttons
are pressed again.
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.
- 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).
- some documentation missing
- Fl_Tile::resize() not satisfying yet
- minimums work, maximums currently ignored
- 0 size children may make program hang
New public methods:
void clear(void);
void clear(Fl_Color val);
old protected methods made public:
void clear_screen(bool scroll_to_hist=true); // ESC [ 2 J
void clear_screen_home(bool scroll_to_hist=true); // ESC [ H ESC [ 2 J
void cursor_home(void); // ESC [ 0 H
test/terminal modified to test these, and added separate tests
for both the API and ANSI code ways to do these ops.
textcolor() needed for consistency, color() behavior documented.
Both added to the test/terminal app.
Elaborated on the special background "see through" color value + behavior,
tested with color() in test/terminal app.
Define GLDEMO_LIBS and GLDEMO_SHARED: these definitions can be used
to build OpenGL demo programs that can also be built w/o OpenGL
Examples: fullscreen, handle_events, unittests
- add CMake option 'OPTION_USE_STD'
- add configure option '--enable-use_std'
- move FL/Fl_String.H to src/Fl_String.H
- move FL/Fl_Int_Vector.H to src/Fl_Int_Vector.H
- remove Fl_String from demo program examples/callbacks.cxx
- remove Fl_Int_Vector from public header FL/Fl_Table.H
- some methods of Fl_Table are no longer inline
- add CMake option OPTION_USE_STD to allow std::string in some
selected functions and methods
Experimental, may be removed before release:
- use either Fl_Int_Vector or std::vector in Fl_Table depending
on CMake OPTION_USE_STD or configure --enable-use_std
Move all fl_filename* functions that use Fl_String to fluid
Main changes in fluid:
- add fluid_filename.h and .cxx
- include "fluid_filename.h" rather than <FL/filename.H>
Update fl_input(), fl_password() and test/ask
- add maxchar parameter to fl_input() and fl_password()
- fl_input_str() and fl_password_str() are optional and return
std::string if enabled (FLTK_USE_STD)
- Fl_Grid: force layout() on resize() - needed for GL subwindows
- test/cube.cxx:
- use end() in constructor of class cube_box
- ensure not to change the current group when adding a button
- FL/Fl_Grid.H: header file
- src/Fl_Grid.cxx: implementation
- examples/grid-simple.cxx: simple example program
- test/cube.cxx: use Fl_Grid for layout
- test/grid_alignment.cxx: test cell alignment and other functions
- test/grid_buttons.cxx: demo program as discussed in fltk.general
- test/grid_login.cxx: like test/flex_login.cxx but with Fl_Grid
- test/flex_login.cxx: modified to match test/grid_login.cxx
- remove static variables and functions
- make move_intersection() virtual
- add (protected) cursor access methods
These changes were inspired by STR 2791 where the user proposing an
enhancement was not able to subclass Fl_Tile properly. This commit
fixes the mentioned issues and enables subclassing without copying
internal code.
... "when there's no current window".
Silently ignore GLUT function calls that need a current window if the
current window is NULL, return 0 from functions that return an 'int'.
Check if window is shown in Fl_X11_Gl_Window_Driver::swap_buffers().
This would issue "XRequest.nnn: GLXBadDrawable 0x0" on X11 otherwise.
Note: the chosen implementation to ignore GLUT calls silently appears
to be compatible with GLUT (3.7) whereas FreeGLUT 3.0 would issue error
messages and exit. The latter could be implemented as well but would
be much more work.
The user can add an arbitrary number of highly configurable
shell commands through the setting panel. The commands can
be saved as user preferences, inside the .fl file, or exported
to an external file. Shell scripts can be limited to individual
platforms, can have shortcut keys, etc. .
* documentation will follow
* support to call `fltk-config` will follow
This code was (and is still) commented out but it *would* trigger
a "stack buffer overflow" error *if* uncommented.
The new code demonstrates how a binary object (Fl_Preferences 'bed')
can be dumped to a preferences file in binary format (if activated).
Todo: fluid-shared can't (yet) be built agains the shared fltk lib
because of some linker errors. Needs investigation.
Note: fluid-shared is basically a test program to demonstrate linking
against the shared FLTK libs but doesn't work yet using VS (MSVC).
This is no problem for the functionality.
fl_filename_absolute can no generate a path using arbitrary source paths.
Fl_Menu_ adds find_item_with_user_data and find_item_with_argument
Fl_String adds find(string, start)
See fltk.general, thread "Is handling simultaneous Left-click and
Right-click drags supported?" from Jul 12, 2023
Status: FL_DRAG operation is terminated when one mouse button is
released, even if more than one button is actually down. Subsequent
mouse movement is reported as FL_MOVE rather than FL_DRAG, this is
under investigation.
