setIntDigits()

void ENumeric::setIntDigits

(

int

i

)

sets number of integer digits to be displayed

Parameters

i	number of digits

Referenced by EApplyNumeric::setIntDigits().

setMaximum()

void ENumeric::setMaximum

(

double

v

)

sets the maximum value of the widget

Parameters

v

setValue()

void ENumeric::setValue

(

double

v

)

sets value displayed by the widget

Parameters

v	the value to be displayed

inline

returns the value displayed by the widget

Returns

the value displayed

valueChanged

void ENumeric::valueChanged ( double  )

signal

Referenced by setValue().
