Detailed Description

The QtxIntSpinBox class represents the widget for entering the integer values. In addition to the functionality provided by QSpinBox, this class supports "cleared" state - this is the state corresponding to "None" (or empty) entered value.

To set "cleared" state use setCleared() method. To check if the spin box stores "cleared" state, use isCleared() method. For example:

  if (mySpinBox->isCleared()) {
    ... // process "None" state
  }
  else {
    int value = mySpinBox->value();
    ... // process entered value
  }

bool QtxIntSpinBox::isCleared

(

)

const

Returns:

true if spin box is cleared

References myCleared.

void QtxIntSpinBox::setCleared

(

const bool

on

)

[virtual]

Parameters:

on	new "cleared" status

References myCleared.

void QtxIntSpinBox::stepBy

(

int

steps

)

[virtual]

The steps value can be any integer number. If it is > 0, the value incrementing is done, otherwise value is decremented steps times.

Parameters:

steps

number of increment/decrement steps

Reimplemented in SalomeApp_IntSpinBox.

void QtxIntSpinBox::onTextChanged

(

const QString &

)

[protected, virtual, slot]

Parameters:

txt	current spin box text (not used)

Reimplemented in SalomeApp_IntSpinBox.

References myCleared.

QString QtxIntSpinBox::textFromValue

(

int

val

)

const [protected, virtual]

Parameters:

val	value being converted

Returns:

string containing the converted value
