On Windows fluid.exe is a "GUI" program and does not allow console
output which can be a problem in automated builds. In Visual Studio
the fluid GUI program would pop up console windows when generating
.cxx and .h files from .fl files.
The new (additional) fluid-cmd.exe is built as console application
for users that need it and it is used in the FLTK build process on
Windows to convert the .fl files.
* Size and position widgets can evaluate basic math.
* Allowing x, y, w, and h as variables for formulas.
Also supporting 'i' as a counting index when selecting multiple
widgets, so setting Y: to i*25+10 arranges all selected widgets
vertically.
* Additional variables cx, etc. for children box
cx, cy, cw, ch
Before, Functions could only be "static" (keyword static is added)
or "global" (prototype is added). This is harmful if the function or
method was declared elsewhere. "local" solves that.
* Added filename function to Fl_Preferences
Static function to get filename before opening.
Member to get filename after opening.
Bug fixes for memory mapped preferences.
* ERROR is a macro on Windows, don't use it
* Added Fl_Preferences::dirty().
User can now check if the database will be written
when flushed or destroyed.
Flush returns a crude error code.
* Fl_Preferences::get binary data returns # of bytes read.
* Verified group deletion code
* Fl_Preferences ignores locale.
This will make .prefs files interchangeable
between different computers.
* Updating the Preferences Mode to ignore locale.
* Fixes in docs.
Reading an .fl file rebuilds a menu item arrays with every item read.
If a menu is only partially read, the end marker (label==NULL) is
not set, so that deleting the menu will run beyond the missing marker.
This bug was exposed by adding images to menu items, which
requires additional deletes.
... as discussed in fltk.coredev in thread "RFC: introduce public
config header <FL/fl_config.h>", see:
https://groups.google.com/g/fltkcoredev/c/xLCs1AIXMVo/m/MHZpQggzAQAJ
- Rename abi-version.h to fl_config.h, rename input files,
update dependencies, .gitignore, CMake, configure and Makefiles.
- Include Cairo options in FL/fl_config.h
- Rename FLTK_USE_CAIRO to FLTK_HAVE_CAIROEXT for consistency.
- Include <FL/fl_config.h> in config.h and wherever necessary,
fix include order (move FL/Fl.H to the top) and more.
- Move USE_X11 to fl_config.h and rename to FLTK_USE_X11
- Do not include <config.h> in Cairo demo program which is no
longer required in Cairo programs since FLTK 1.4.0
In Fluid, selecting a menu button, and selecting it again to make it
movable would also grab the text input focus, which would prevent
the enclosing window from using arrow key events to manipulate
the selected widget.
Code now convinces browser to rebuild when the tree changes by UI.
When widgets are move, the current widget should always be visible.
It's the responsibility of the UI callback to update the browser.
