Detailed Description

KDE debug message streams let you and the user control just how many debug messages you see.

Debug message printing is controlled by (un)defining QT_NO_DEBUG when compiling your source. If QT_NO_DEBUG is defined then debug messages are not printed by default but can still be enabled by runtime configuration, e.g. via kdebugdialog or by editing kdebugrc.

You can also control what you see: process name, area name, method name, file and line number, timestamp, etc. using environment variables. See http://techbase.kde.org/SysAdmin/Environment_Variables#KDE_DEBUG_NOPROCESSINFO

Macro Definition Documentation

#define k_funcinfo   ""

An indicator of where you are in a source file, to be used in warnings (perhaps debug messages too).

Deprecated:

kDebug takes care of printing the method name automatically now

Definition at line 67 of file kdebug.h.

#define k_lineinfo   "[" << __FILE__ << ":" << __LINE__ << "] "

An indicator of where you are in a source file, to be used in warnings (perhaps debug messages too).

Gives an accurate idea of where the message comes from. Not suitable for user-visible messages.

Deprecated:

kDebug takes care of printing the method name automatically now

Definition at line 76 of file kdebug.h.

#define KDE_DEBUG_ENABLED_BY_DEFAULT   true

Definition at line 59 of file kdebug.h.

#define KDE_DEFAULT_DEBUG_AREA   0

Definition at line 121 of file kdebug.h.

#define kDebug   KDebug(QtDebugMsg, __FILE__, __LINE__, Q_FUNC_INFO)

Definition at line 316 of file kdebug.h.

#define KDEBUG_BLOCK   KDebug::Block _kDebugBlock(Q_FUNC_INFO);

Convenience macro for making a standard KDebug::Block.

Definition at line 372 of file kdebug.h.

#define kWarning   KDebug(QtWarningMsg, __FILE__, __LINE__, Q_FUNC_INFO)

Definition at line 322 of file kdebug.h.

#define KWARNING_DEPRECATED   kWarning() << "DEPRECATED";

Convenience macro, use this to alert other developers to stop using a function The function name will appear in the output (unless $KDE_DEBUG_NOMETHODNAME is set)

Since

4.6

Definition at line 399 of file kdebug.h.

#define KWARNING_NOTIMPLEMENTED   kWarning() << "NOT-IMPLEMENTED";

Convenience macro, use this to remind yourself to finish the implementation of a function The function name will appear in the output (unless $KDE_DEBUG_NOMETHODNAME is set)

Since

4.6

Definition at line 392 of file kdebug.h.
