Detailed Description

Macro Definition Documentation

#define GSAFE_VERSION   "1.3.8"

The version of gsafe

Definition at line 39 of file datalib.h.

#define HASHMUL   1.5

This multiplier is used in HSqlChoose. It is determine the over allocation of the hash table. If the multiplier is bigger, it will be less collision but will use more memory. Must be greater than 1.0.

Definition at line 55 of file datalib.h.

Function Documentation

QStringList* deep_copy_stringlist	(	QStringList *	target,
		QStringList *	source
	)

Deepcopy a stringlist to another

Definition at line 54 of file datalib.cpp.

QString doubleToQString	(	double	val,
		int	min,
		int	max,
		int	group
	)

Converts a double value to QString. It uses the my_dtoa function inside.

my_dtoa

Definition at line 273 of file datalib.cpp.

double dRound	(	double	val,
		int	mode = ROUND_MATH
	)

Round a double value.

Parameters

val	the value to round
mode	the round mode. Can be ROUND_MATH or ROUND_FLOOR

Definition at line 286 of file datalib.cpp.

void error

(

QString

s

)

Pops up an error message with QMessageBox. You can call this function everywhere in the program. (It blocks the execution)

Parameters

s	the error string

int my_dtoa	(	double	v,
		char *	buffer,
		int	bufflen,
		int	min,
		int	max,
		int	group
	)

Converts a double value to char * string

Parameters

v	the double value to convert
buffer	the buffer wehre the string is written
bufflen	the size of the buffer. (limits the max length of converted string)
min	specified the minimum displayed decimal digit fragments.
max	specified the maximum displayed decimal digit fragments.
group	the displayed digits will be groupped by three digit. (if group==1 means "2334455.34" displayed "2 334 455.45" )

Returns

1 if the buffer is smaller size than needed, 0 otherwise
