* CMake integration, no autotiools
* alignment panel is now correctly renamed to setting panel
* source view is now correctly renamed to code view
* Merge FLTK FLUID docs into FLUID user manual.
* Add two simple entry tutorials
* Remove FLUID chapter form FLTK docs.
* GitHub action to generate HTML and PDF docs and
make the available as artefacts
* this commit introduces a few FIXMEs and TODOs that probably
can't be solved until we do some major refactoring. They work for
now, but adding more layout controlling widgets will be hard.
Ctrl-0 is used by FLTK globally to zoom all windows back to 100%,
so FLUID should not override that. Loading the previous file is now
Ctrl-1 instead of Ctrl-0.
* interactive layout alignment rewritten
* interface for new alignment rules
* new alignment dialog box
* user defined layout rules added
* layout rules can be stored in projects, settings, and external files
* Valgrind verification
* Full support o when()
* Making undo suspend nesting
* Finally correct undo handling for Label: input
* Documentation.
* Adding more undo checkpoints for the Widget Panel
* Quick selection of default user_data types
* Pulldown menu for system colors
* Make sure that partially typed text fields are propagated before saving
* 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
In this first version, we assume that the code file is newer whenever it is written,
until the current design is modified in any way. So instead of a status bar at the bottom
of the main window, the title bar will now show the status of the design and the code at
the same place.
tl;dr : making Fluid maintainable, no changes in code execution and logic.
This is a pretty extensive restructuring of the Fluid source tree.
It was neccessary because source and header files were getting
much too big to handle. Many source files had no header, and many
headers declared functions that were in diffrent source files.
Reorganized much of the include statements.
Added comments to some of the files.
Added Doxygen configuration file for standalone Fluid docs.
Tested everything by rebuilding Fluid .fl designs with the resorted
version of Fluid.
