Detailed Description

A QDoubleSpinBox allowing to customize numbers display with respect to.

It allows the user to specify a custom display format.

Constructor & Destructor Documentation

◆ DoubleSpinBox()

DoubleSpinBox::DoubleSpinBox	(	const char	format = `'g'`,
		QWidget *	parent = `nullptr`
	)

Constructor.

Parameters

format	format used to display numbers: has the same meaning as in QLocale::toString ( double i, char f = 'g', int prec = 6 )
parent	parent widget (only affects placement of the dialog)

Definition at line 15 of file DoubleSpinBox.cpp.

References d_format, d_prec, d_value, and interpretText().

Member Function Documentation

◆ activated

void DoubleSpinBox::activated ( DoubleSpinBox * )

signal

Signal emitted when the spin box gains focus.

Referenced by focusInEvent().

◆ addSpecialTextMapping()

void DoubleSpinBox::addSpecialTextMapping	(	const QString &	text,
		double	value
	)

Adds a mapping from string whihc may be entered into the edit box and a double value.

The mapping is case sensitive

Parameters

text	QString with text to map
value	Value to map it to

◆ getMaximum()

double DoubleSpinBox::getMaximum ( )

Definition at line 39 of file DoubleSpinBox.cpp.

References d_max_val.

◆ getMinimum()

double DoubleSpinBox::getMinimum ( )

Definition at line 48 of file DoubleSpinBox.cpp.

References d_min_val.

◆ interpretText

void DoubleSpinBox::interpretText ( bool notify = true )

privateslot

Interpret the text and update the stored value.

Parameters

notify If true then emit signals to indicate if the value has changed (default=true) The default is important so that connected signals ensure the correct updates are pushed through but we need to be able to turn them off as there are cases where this causes a recursive call.
