Detailed Description

qtLineEdit subclass that supports a low precision view when inactive

qtDoubleLineEdit allows to edit a real number in full precision and display a simplified version when the widget is not in focus or under mouse pointer.

The precision and notation associated with the displayed number can be configured using the precision and notation properties on the qtDoubleLineEdit instance. Additionally, qtDoubleLineEdit can be configure to simply respect a global precision and notation specification by using the property useGlobalPrecisionAndNotation (which is default).

Since qtDoubleLineEdit is intended for numeric values, in its constructor, a QDoubleValidator is created for convenience.

This is from ParaView's pqDoubleLineEdit class. Changes pqInternals -> qtInternals and the class uses the smtk::extension namespace

Member Function Documentation

◆ notation()

RealNumberNotation smtk::extension::qtDoubleLineEdit::notation ( ) const

Return the notation used to display the number.

See also: setNotation()

◆ precision()

int smtk::extension::qtDoubleLineEdit::precision ( ) const

Return the precision used to display the number.

See also: setPrecision()

◆ setGlobalPrecisionAndNotation()

void qtDoubleLineEdit::setGlobalPrecisionAndNotation	(	int	precision,
		RealNumberNotation	notation
	)

static

Get/set the global precision and notation.

All qtDoubleLineEdit instances that have useGlobalPrecisionAndNotation property set to true will automatically respect the state set on the global variables.

◆ setNotation

void qtDoubleLineEdit::setNotation ( qtDoubleLineEdit::RealNumberNotation _notation )

slot

Set the notation used to display the number.

See also: notation()

◆ setPrecision

void qtDoubleLineEdit::setPrecision ( int precision )

slot

Set the precision used to display the number.

See also: precision()

◆ setUseGlobalPrecisionAndNotation

void qtDoubleLineEdit::setUseGlobalPrecisionAndNotation ( bool value )

slot

Set whether to use global precision and notation values.

Default is true.

See also: useGlobalPrecisionAndNotation()

◆ simplifiedText()

QString qtDoubleLineEdit::simplifiedText ( ) const

Returns the text being shown when the widget is not active or under mouse pointer.

Primarily intended for test or debugging purposes.

◆ useGlobalPrecisionAndNotation()

bool smtk::extension::qtDoubleLineEdit::useGlobalPrecisionAndNotation ( ) const

useGlobalPrecisionAndNotation indicates if the qtDoubleLineEdit should use global precision and notation values instead of the parameters specified on this instance.

Default is true.
