Deprecated functions
From time to time I do a fresh trunk compile to entertain myself on the logs (as I have no time to do real development at the moment).
So this is the top list of warnings about deprecated functions:
168 'insertItem' is deprecated (declared at build/qt-copy/include/QtGui/../../../../qt-copy/src/gui/widgets/qmenu.h:170) 156 '__base_ctor ' is deprecated (declared at build/qt-copy/include/QtGui/../../../../qt-copy/src/gui/kernel/qwidget.h:191) 146 '__comp_ctor ' is deprecated (declared at build/qt-copy/include/QtGui/../../../../qt-copy/src/gui/kernel/qgridlayout.h:53) 123 '__comp_ctor ' is deprecated (declared at build/qt-copy/include/QtGui/../../../../qt-copy/src/gui/kernel/qboxlayout.h:113) 123 ‘bitBlt’ is deprecated (declared at build/qt-copy/include/QtGui/../../../../qt-copy/src/gui/painting/qpaintdevice.h:126) 86 'setItemChecked' is deprecated (declared at build/qt-copy/include/QtGui/../../../../qt-copy/src/gui/widgets/qmenu.h:259) 75 '__comp_ctor ' is deprecated (declared at build/qt-copy/include/QtGui/../../../../qt-copy/src/gui/kernel/qboxlayout.h:133) 74 ‘insertItem’ is deprecated (declared at build/qt-copy/include/Qt/../../../../qt-copy/src/gui/widgets/qcombobox.h:257) 69 ‘__comp_ctor ’ is deprecated (declared at build/qt-copy/include/QtGui/../../../../qt-copy/src/gui/kernel/qboxlayout.h:113) 65 'insertItem' is deprecated (declared at build/qt-copy/include/Qt/../../../../qt-copy/src/gui/widgets/qcombobox.h:257) 64 'addMultiCellWidget' is deprecated (declared at build/qt-copy/include/QtGui/../../../../qt-copy/src/gui/kernel/qgridlayout.h:123) 59 ‘__comp_ctor ’ is deprecated (declared at build/qt-copy/include/QtGui/../../../../qt-copy/src/gui/kernel/qgridlayout.h:53) 57 'latin1' is deprecated (declared at build/qt-copy/include/QtCore/../../../../qt-copy/src/corelib/tools/qstring.h:428) 54 'setPixmap' is deprecated (declared at build/qt-copy/include/QtGui/../../../../qt-copy/src/gui/widgets/qabstractbutton.h:132) 54 ‘setCurrentItem’ is deprecated (declared at build/qt-copy/include/Qt/../../../../qt-copy/src/gui/widgets/qcombobox.h:237) 54 'insertItem' is deprecated (declared at build/qt-copy/include/QtGui/../../../../qt-copy/src/gui/widgets/qmenu.h:157) 54 '__comp_ctor ' is deprecated (declared at inst/include/kaction.h:276) 52 'find' is deprecated (declared at build/qt-copy/include/QtCore/../../../../qt-copy/src/corelib/tools/qstring.h:450) 51 'insertSeparator' is deprecated (declared at build/qt-copy/include/QtGui/../../../../qt-copy/src/gui/widgets/qmenu.h:191) 51 'insertItem' is deprecated (declared at build/qt-copy/include/QtGui/../../../../qt-copy/src/gui/widgets/qmenu.h:173) 40 'repaint' is deprecated (declared at build/qt-copy/include/QtGui/../../../../qt-copy/src/gui/kernel/qwidget.h:726) 40 ‘__base_ctor ’ is deprecated (declared at build/qt-copy/include/QtGui/../../../../qt-copy/src/gui/kernel/qwidget.h:191) 37 'setItemEnabled' is deprecated (declared at build/qt-copy/include/QtGui/../../../../qt-copy/src/gui/widgets/qmenu.h:250) 37 'data' is deprecated (declared at build/qt-copy/include/QtCore/../../../../qt-copy/src/corelib/tools/qmap.h:270) 37 '__comp_ctor ' is deprecated (declared at inst/include/kactivelabel.h:42) 36 'lower' is deprecated (declared at build/qt-copy/include/QtCore/../../../../qt-copy/src/corelib/tools/qstring.h:477) 35 'find' is deprecated (declared at build/qt-copy/include/QtCore/../../../../qt-copy/src/corelib/tools/qstring.h:448) 32 'currentItem' is deprecated (declared at build/qt-copy/include/Qt/../../../../qt-copy/src/gui/widgets/qcombobox.h:236) 32 '__comp_ctor ' is deprecated (declared at inst/include/ktoggleaction.h:125) 31 'fromPathOrUrl' is deprecated (declared at inst/include/kurl.h:859) 31 deprecated conversion from string constant to 'char*'' 31 '__comp_ctor ' is deprecated (declared at inst/include/kaction.h:331) 28 'start' is deprecated (declared at build/qt-copy/include/QtCore/../../../../qt-copy/src/corelib/kernel/qtimer.h:67) 28 ‘setPixmap’ is deprecated (declared at build/qt-copy/include/QtGui/../../../../qt-copy/src/gui/widgets/qabstractbutton.h:132)
So if you're interested, you can make any of these warnings an error for yourself and recompile to port the warnings away. But make sure know what you're doing.
