Detailed Description

The QgsSpinBox is a spin box with a clear button that will set the value to the defined clear value.

The clear value can be either the minimum or the maiximum value of the spin box or a custom value.

This value can then be handled by a special value text.

Constructor & Destructor Documentation

◆ QgsDoubleSpinBox()

QgsDoubleSpinBox::QgsDoubleSpinBox ( QWidget * parent = nullptr )

explicit

Constructor for QgsDoubleSpinBox.

Parameters

parent parent widget

Member Function Documentation

◆ changeEvent()

void QgsDoubleSpinBox::changeEvent ( QEvent * event )

overrideprotected

Definition at line 73 of file qgsdoublespinbox.cpp.

◆ clear()

void QgsDoubleSpinBox::clear ( )

override

Sets the current value to the value defined by the clear value.

Definition at line 171 of file qgsdoublespinbox.cpp.

◆ clearValue()

double QgsDoubleSpinBox::clearValue ( ) const

Returns the value used when clear() is called.

See also: setClearValue()

Definition at line 216 of file qgsdoublespinbox.cpp.

◆ editingTimeout

void QgsDoubleSpinBox::editingTimeout ( double value )

signal

Emitted when either:

1 second has elapsed since the last value change in the widget (eg last key press or scroll wheel event)
or, immediately after the widget has lost focus after its value was changed.

This signal can be used to respond semi-instantly to changes in the spin box, without responding too quickly while the user in the middle of setting the value.

Since: QGIS 3.42

◆ editingTimeoutInterval()

int QgsDoubleSpinBox::editingTimeoutInterval ( ) const

Returns the timeout (in milliseconds) threshold for the editingTimeout() signal to be emitted after an edit.

Since: QGIS 3.42

Definition at line 144 of file qgsdoublespinbox.cpp.

◆ expressionsEnabled()

bool QgsDoubleSpinBox::expressionsEnabled ( ) const

inline

Returns whether the widget will allow entry of simple expressions, which are evaluated and then discarded.

Returns: true if spin box allows expression entry

◆ setClearValue()

void QgsDoubleSpinBox::setClearValue	(	double	customValue,
		const QString &	clearValueText = `QString()`
	)

Defines the clear value as a custom value and will automatically set the clear value mode to CustomValue.

Parameters

customValue	defines the numerical value used as the clear value
clearValueText	is the text displayed when the spin box is at the clear value. If not specified, no special value text is used.

	)

Defines if the clear value should be the minimum or maximum values of the widget or a custom value.

Parameters

mode	mode to user for clear value
clearValueText	is the text displayed when the spin box is at the clear value. If not specified, no special value text is used.
