Detailed Description

The QgsTimeEdit class is a QTimeEdit widget with the capability of setting/reading null date/times.

Warning: You should use the signal valueChanged of this subclass rather than QDateTimeEdit::timeChanged. (If you consequently connect parent's timeChanged signal and call time() afterwards there is no guarantee that NULL values will be correctly handled).

Constructor & Destructor Documentation

◆ QgsTimeEdit()

QgsTimeEdit::QgsTimeEdit ( QWidget * parent = nullptr )

explicit

Constructor for QgsTimeEdit.

The current time is used by default. The widget is allowing null by default. If allow null is disabled, you should check allowNull before getting values from the widget.

Definition at line 365 of file qgsdatetimeedit.cpp.

Member Function Documentation

◆ emitValueChanged()

void QgsTimeEdit::emitValueChanged ( const QVariant & value )

overrideprotectedvirtual

Emits the widget's correct value changed signal.

Reimplemented from QgsDateTimeEdit.

Definition at line 392 of file qgsdatetimeedit.cpp.

◆ setTime()

void QgsTimeEdit::setTime ( const QTime & time )

Sets the time for the widget and handles null times.

Note: Since QDateTimeEdit::setTime() is not virtual, setTime must be called for QgsTimeEdit.

Definition at line 371 of file qgsdatetimeedit.cpp.

◆ timeValueChanged

void QgsTimeEdit::timeValueChanged ( const QTime & time )

signal

Signal emitted whenever the time changes.
