From 51a55bc73660f64e8f4b32b8b4d3858f2a786f7b Mon Sep 17 00:00:00 2001 From: Matthias Melcher Date: Sun, 16 Mar 2025 17:16:12 -0400 Subject: Fluid: restructuring and rejuvenation of the source code. * Add classes for application and project * Removed all globals from Fluid.h * Extracting args and project history into their own classes * Moving globals into Application class * Initialize values inside headers for some classes. * Undo functionality wrapped in a class inside Project. * File reader and writer are now linked to a project. * Avoid global project access * Nodes (former Types) will be managed by a new Tree class. * Removed static members (hidden globals) form Node/Fl_Type. * Adding Tree iterator. * Use nullptr instead of 0, NULL, or 0L * Renamed Fl_..._Type to ..._Node, FL_OVERRIDE -> override * Renaming ..._type to ...::prototype * Splitting Widget Panel into multiple files. * Moved callback code into widget panel file. * Cleaning up Fluid_Image -> Image_asset * Moving Fd_Snap_Action into new namespace fld::app::Snap_Action etc. * Moved mergeback into proj folder. * `enum ID` is now `enum class Type`. --- fluid/nodes/Grid_Node.h | 82 +++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 82 insertions(+) create mode 100644 fluid/nodes/Grid_Node.h (limited to 'fluid/nodes/Grid_Node.h') diff --git a/fluid/nodes/Grid_Node.h b/fluid/nodes/Grid_Node.h new file mode 100644 index 000000000..4363164ee --- /dev/null +++ b/fluid/nodes/Grid_Node.h @@ -0,0 +1,82 @@ +// +// Grid Node header file for the Fast Light Tool Kit (FLTK). +// +// Copyright 2023-2025 by Bill Spitzak and others. +// +// This library is free software.
