Member Function Documentation

◆ load()

void Wt::WTimeEdit::load ( )
overridevirtual

Loads content just before the widget is used.

This function is called when a widget is inserted in the widget hierarchy. Widgets that get inserted in the widget hierarchy will be rendered. Visible widgets are rendered immediately, and invisible widgets in the back-ground (or not for a plain HTML session). This method is called when the widget is directly or indirectly inserted into the widget tree.

The default implementation simply propagates the load signal to its children. You may want to override this method to delay loading of resource-intensive contents.

During the life-time of a widget, this method may be called multiple times, so you should make sure that you do a deferred initialization only once.

Reimplemented from Wt::WInteractWidget.

◆ propagateSetEnabled()

void Wt::WTimeEdit::propagateSetEnabled ( bool  enabled)
overrideprotectedvirtual

Propagates that a widget was enabled or disabled through children.

When enabling or disabling a widget, you usually also want to disable contained children. This method is called by setDisabled() to propagate its state to all children.

You may want to reimplement this method if they wish to render differently when a widget is disabled. The default implementation will propagate the signal to all children.

Reimplemented from Wt::WFormWidget.

◆ render()

void Wt::WTimeEdit::render ( WFlags< RenderFlag flags)
overrideprotectedvirtual

Renders the widget.

This function renders the widget (or an update for the widget), after this has been scheduled using scheduleRender().

The default implementation will render the widget by serializing changes to JavaScript and HTML. You may want to reimplement this widget if you have been postponing some of the layout / rendering implementation until the latest moment possible. In that case you should make sure you call the base implementation however.

Reimplemented from Wt::WLineEdit.

◆ setHidden()

void Wt::WTimeEdit::setHidden ( bool  hidden,
const WAnimation animation = WAnimation() 
)
overridevirtual

Sets the hidden state of this widget.

If the widget has a label, it is hidden and shown together with this widget.

Reimplemented from Wt::WFormWidget.

◆ setTime()

void Wt::WTimeEdit::setTime ( const WTime time)

Sets the time.

Does nothing if the current time is Null.

See also
time()

◆ setWrapAroundEnabled()

void Wt::WTimeEdit::setWrapAroundEnabled ( bool  rollover)

Enables or disables wraparound.

Wraparound is enabled by default

◆ time()

WTime Wt::WTimeEdit::time ( ) const

Returns the time.

Returns an invalid time (for which WTime::isValid() returns false) if the time could not be parsed using the current format().

See also
setTime(), WTime::fromString(), WLineEdit::text()

◆ timeValidator()

std::shared_ptr< WTimeValidator > Wt::WTimeEdit::timeValidator ( ) const
virtual

Returns the validator.
