Macro Definition Documentation

FUTURE_TR_NOOP

#define FUTURE_TR_NOOP

(

x

)

Value:

(x)

Macros for marking future QT_TR_NOOP translations.

Definition at line 166 of file KDbGlobal.h.

futureTr

#define futureTr   QString

Macros for marking future Qt tr() translations.

Definition at line 160 of file KDbGlobal.h.

futureTr2

#define futureTr2	(		a,
			b )

Value:

QString(b)

Definition at line 161 of file KDbGlobal.h.

KDB_IS_VERSION

#define KDB_IS_VERSION	(		a,
			b,
			c )

Value:

( KDB_VERSION >= KDB_MAKE_VERSION(a,b,c) )

Check if the KDb version matches a certain version or is higher.

This macro is typically used to compile conditionally a part of code:

#if KDB_IS_VERSION(3, 1, 0)
// Code for KDb 3.1
#else
// Code for KDb older than 3.1
#endif

Warning

Especially during development phases of KDb, be careful when choosing the version number that you are checking against. Otherwise you might risk to break the next KDb release. Therefore be careful that development version have a version number lower than the released version, so do not check e.g. for KDb 3.1 with KDB_IS_VERSION(3, 1, 0) but with the actual version number at a time a needed feature was introduced, e.g. KDB_IS_VERSION(3, 0, 90) for beta 3.1

KDB_MAKE_VERSION

#define KDB_MAKE_VERSION	(		a,
			b,
			c )

Value:

(((a) << 16) | ((b) << 8) | (c))

Make a number from the major, minor and release number of a KDb version.

This function can be used for preprocessing when KDB_IS_VERSION is not appropriate.
