Constructor & Destructor Documentation

ModuleBase_ParamIntSpinBox()

ModuleBase_ParamIntSpinBox::ModuleBase_ParamIntSpinBox ( QWidget *  theParent = 0 )

explicit

Constructor.

Constructs a spin box with 0.0 as minimum value and 99.99 as maximum value, a step value of 1.0 and a precision of 2 decimal places. The value is initially set to 0.00.

Parameters

theParent

a parent object

~ModuleBase_ParamIntSpinBox()

ModuleBase_ParamIntSpinBox::~ModuleBase_ParamIntSpinBox ( )

virtual

Destructor.

Member Function Documentation

stepBy()

void ModuleBase_ParamIntSpinBox::stepBy ( int  steps )

virtual

Perform steps increment/decrement steps.

Re-implemented to handle cases when Notebook variable name is specified by the user as the widget text. Otherwise, simply calls the base implementation.

Parameters

steps

number of increment/decrement steps

valueFromText()

int ModuleBase_ParamIntSpinBox::valueFromText ( const QString &  theText ) const

virtual

Convert Int value from text string.

textFromValue()

QString ModuleBase_ParamIntSpinBox::textFromValue ( int  theValue ) const

virtual

Convert text string from int value.

validate()

QValidator::State ModuleBase_ParamIntSpinBox::validate ( QString &  str, int &  pos  ) const

virtual

Validate the value.

This function is used to determine whether input is valid.

Parameters

str	currently entered value
pos	cursor position in the string

Returns

validating operation result

setValue()

void ModuleBase_ParamIntSpinBox::setValue ( int  value )

virtual

Set current int value.

This function is used to set a current value for this spinbox.

Parameters

value

current value

The new value is ignored if the spinbox has a variable.

setText()

void ModuleBase_ParamIntSpinBox::setText ( const QString &  value )

virtual

Set current text value.

This function is used to set a text for this spinbox.

Parameters

value

current value

setAcceptVariables()

void ModuleBase_ParamIntSpinBox::setAcceptVariables

(

const bool

flag

)

Set a flag about accepted variable.

Enables or disables variable names in the spin box. By default, variable names are enabled.

Parameters

flag	If true, variable names are enabled.

isAcceptVariables()

bool ModuleBase_ParamIntSpinBox::isAcceptVariables

(

)

const

Returns accepted variables flag.

Returns true if the spin box accepts variable names.

hasVariable() [1/2]

bool ModuleBase_ParamIntSpinBox::hasVariable

(

)

const

Returns True if the input value contains variable.

hasVariable() [2/2]

bool ModuleBase_ParamIntSpinBox::hasVariable ( const QString &  theText ) const

protected

Returns True if the given text contains variable.

Parameters

theText

a text string

isValid()

ModuleBase_ParamIntSpinBox::State ModuleBase_ParamIntSpinBox::isValid ( const QString &  theText, double &  theValue  ) const

protected

Returns state of the control.

This function is used to determine whether input is valid.

Returns

validating operation result

checkRange()

bool ModuleBase_ParamIntSpinBox::checkRange ( const double  theValue ) const

protected

Returns True if the given value is within min and max of the control.

This function is used to check that string value lies within predefined range.

Returns

check status

findVariable()

bool ModuleBase_ParamIntSpinBox::findVariable ( const QString &  theName, double &  outValue  ) const

protected

Finds a variable by its name.

This function is used to determine whether input is a variable name and to get its value.

Returns true in success

Parameters

theName	a name of variable
outValue	an output value of the variable

Returns

status of search operation

showEvent()

void ModuleBase_ParamIntSpinBox::showEvent ( QShowEvent *  theEvent )

protectedvirtual

This function is called when the spinbox receives show event.

onTextChanged

void ModuleBase_ParamIntSpinBox::onTextChanged ( const QString &  text )

protectedslot

A slot called on text change.

keyPressEvent()

void ModuleBase_IntSpinBox::keyPressEvent ( QKeyEvent *  theEvent )

protectedvirtualinherited

Called on key press event.
