o Fix STR#2828 (E): {Vertical|Widget} Gap o Moved Fabien's reselected methods to Fl_Tree_Prefs, return method made const, doxygen, removed underbars from methods (to follow general API) o Widgets can now appear to the right of labels. This can be controlled with item_draw_mode(FL_TREE_ITEM_DRAW_LABEL_AND_WIDGET) o Cleaned up Fl_Tree_Item::draw(), Fl_Tree::draw() o New methods: marginbottom() -- [ABI feature] extra space below last tree element when scrolling widgetmarginleft() -- [ABI feature] space to left of widget usericonmarginleft() -- space to left of usericon labelmarginleft() -- space to left of label item_draw_mode() -- control how items, widget() are drawn o Updated Fl_Tree docs, tree-elements.png o test/tree: added sliders to test the above new features, added "open all" and "close all" buttons o Probably other stuff.. TODO: Fix "scroll-beyond-bottom" (STR#2796) TODO: Fix other items in STR#2828 git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@9377 ea41ed52-d2ee-0310-a9c1-e6b18d33e121 |

FLTK EXAMPLE PROGRAMS --------------------- This directory contains example FLTK programs that demonstrate recommended programming practices and techniques for FLTK application programmers. The "*-simple.cxx" files are a good starting point for those new to FLTK. The programs in this directory are NOT built automatically when you build FLTK; you have to manually build them. The goals of these example programs: o Show good programming style for app programmers to emulate o Show simple examples of how to use widgets to new users of FLTK. o Show intermediate or advanced examples of techniques often misused or hard to document o Demonstrate code that are FAQs on the newsgroup forum. (such as how to use threads, callbacks, etc) o Example code should be short, but not at the expense of clarity. o Where possible, examples should emphasize FLTK's simplicity. NEW SUBMISSIONS: RECOMMENDED PRACTICES These programs must follow FLTK coding style as defined in the FLTK "CMP" (Configuration Management Plan/Coding Standards). Example code should have the above goals in mind. The best examples are those that are as short and clear as possible; terse, but not at the expense of clarity. To avoid cluttering up the top level directory with ancillary files (such as image files or icons), examples that depend on more than just a .cxx/.h file pair should have their own subdirectory. Data files common to several examples should be located in the examples/data directory. Ancillary data files should be as small as possible, to keep the distribution tar files small. Avoid high resolution images or uncompressed images when possible. Examples that need large data sets (HD images, etc) should not be part of the FLTK distribution; they can be provided as separate packages (eg. as articles or external links). Some widgets have multiple capabilities that are best demonstrated separately. For instance, the table widget can be used as a custom data table, or as a spreadsheet, or as a widget container. So separate examples for each would be e.g. "table-custom-data.cxx", "table-spreadsheet.cxx", "table-widget-container.cxx", etc. Example programs should contain comments that help understand the concepts shown, but not so verbose as to dwarf the code or make the code hard to read. Within code, it's best to use single line comments to emphasize code that might be unclear. Let the code speak as much as possible. Examples programs may be referred to from the documentation as good examples on how to do particular programming techniques. NAMING CONVENTIONS Example programs that demonstrate a particular widget should start with that widget's name in lowercase, eg. "table.cxx" for Fl_Table. Demonstrations of a particular technique should start with "howto-xxx.cxx" to avoid naming conflicts with future widgets of the same name. xxx-simple.cxx -- Simplest possible example of widget xxx eg. table-simple.cxx xxx-<technique>.cxx -- A particular "technique" using widget xxx eg. "table-spreadsheet.cxx" howto-<technique>.cxx -- Demonstrate a particular technique, eg. "howto-threading.cxx" Some example programs may depend on multiple files. To avoid cluttering up the top level examples directory, such examples will have their own subdirectory with the files they depend on localized to that directory. Example programs should be as small as possible, to keep the distribution tar files small. Very large examples, or examples that depend on large data sets should be submitted as separate articles on the FLTK site, or as external links on the FLTK site's 'links' page. HISTORY Previous to FLTK 1.3.0, the fltk/test directory served the dual purpose of containing test suites as well as example code. But the fltk/test programs started becoming necessarily complex, testing for obscure problems, and not necessarily good demos for applications programmers. The fltk/examples directory was created in FLTK 1.3.0 to separate 'good programming examples' from the test suite code. DISCLAIMER The examples in this directory are provided 'as-is', without any express or implied warranty. In no event will the authors be held liable for any damages arising from the use of this software. BUGS If you find a bug, please report it through the fltk STR form at http://fltk.org/str.php
