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 that show particular + 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 demonstrate recommended techniques the FLTK + developers think application programmers should use in their own + applications. + + 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 very large data sets 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 common uses 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. + Property changes on: branches/branch-1.3/examples/README.examples ___________________________________________________________________ Name: svn:eol-style + native Added: branches/branch-1.3/examples/tabs-simple.cxx =================================================================== --- branches/branch-1.3/examples/tabs-simple.cxx (rev 0) +++ branches/branch-1.3/examples/tabs-simple.cxx 2010-06-06 20:28:37 UTC (rev 7628) @@ -0,0 +1,87 @@ +// +// "$Id$" +// +// Simple Fl_Tabs widget example. +// Originally from erco's cheat sheet 06/05/2010, permission by author. +// +// Copyright 1998-2010 by Bill Spitzak and others. +// +// This library is free software; you can redistribute it and/or +// modify it under the terms of the GNU Library General Public +// License as published by the Free Software Foundation; either +// version 2 of the License, or (at your option) any later version. +// +// This library is distributed in the hope that it will be useful, +// but WITHOUT ANY WARRANTY; without even the implied warranty of +// MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
