There is a script - in tdesdk/scripts called "fixheaders" that takes care of most of these - cases. Just call "make -k 2>&1 | perl .../fixheaders" and it will try - to look after the error messages and add includes as it recognize the - errors.<P> - - Also, if your code does not compile and complains about missing member - functions, you should check for methods that started with get...(). - These methods have been renamed to xy*() for consistency.<P> - -<H4><P ALIGN="RIGHT"><A HREF="#TOC">Return to the Table of Contents</A></P></H4> - -<H3><A NAME="automoc">automoc/am_edit, Makefile.am tags</A></H3> - - On the subject of the compilation framework, automoc has been removed from - the admin directory.

Replace kapp->getIconLoader()->loadIcon() with - BarIcon() or use TDEGlobal::iconLoader() instead of getIconLoader()<P> - - kde_*dir() have been removed as they require a unique top level directory - for all applications (TDEDIR). This concept doesn't exist in KDE 2.0 - any more, it has been replaced with "multiple levels of directories", - set in TDEDIRS, so that it's possible to have global settings and - group settings, applied before user settings.<P> - - Replace code that uses kde_*dir() + filename with calls to - locate(filetype, filename) where filetype is what * used to be - in kde_*dir(). locate is defined as function in kstddirs.h to call - TDEGlobal::dirs()->findResource.<P> - - Use locateLocal to get the path of a writable file. For instance, - TDEApplication::localconfigdir()+filename is now locateLocal( "config", filename ), - but for most cases, simply using TDEGlobal::config() is enough, if you're happy - with saving the application's configuration into appnamerc, or - KSimpleConfig cfg("anothercfgfile") to create a config file with another name.<P> - - generalFont() and fixedFont() are deprecated and will be removed soon. - Please use TDEGlobalSettings::generalFont() and TDEGlobalSettings::fixedFont() instead.<P> - - appName() is deprecated.
