Method Detail

setValue

public void setValue(LocalDateTime value)

Sets the selected date and time value of the component. The value can be cleared by setting null.

The value will be truncated to millisecond precision, as that is the maximum that the time picker supports. This means that AbstractField.getValue() might return a different value than what was passed in.

Overrides:

setValue in class com.vaadin.flow.component.AbstractField<DateTimePicker,LocalDateTime>

value - the LocalDateTime instance representing the selected date and time, or null

setReadOnly

public void setReadOnly(boolean readOnly)

Specified by:

setReadOnly in interface com.vaadin.flow.component.HasValue<com.vaadin.flow.component.AbstractField.ComponentValueChangeEvent<DateTimePicker,LocalDateTime>,LocalDateTime>

Specified by:

setReadOnly in interface com.vaadin.flow.component.HasValueAndElement<com.vaadin.flow.component.AbstractField.ComponentValueChangeEvent<DateTimePicker,LocalDateTime>,LocalDateTime>

setLabel

public void setLabel(String label)

Sets the label for this field.

Specified by:

setLabel in interface com.vaadin.flow.component.HasLabel

Parameters:

label - the String value to set

getLabel

public String getLabel()

Gets the label of this field.

Specified by:

getLabel in interface com.vaadin.flow.component.HasLabel

Returns:

the label property of the date time picker

setDatePlaceholder

public void setDatePlaceholder(String placeholder)

Sets a placeholder string for the date field.

Parameters:

getTimePlaceholder

public String getTimePlaceholder()

Gets the placeholder string of the time field.

Returns:

the placeholder property of the time picker

setStep

public void setStep(Duration step)

Sets the step property of the time picker using duration. It specifies the intervals for the displayed items in the time picker dropdown and also the displayed time format.

The set step needs to evenly divide a day or an hour and has to be larger than 0 milliseconds. By default, the format is hh:mm (same as * Duration.ofHours(1)

If the step is less than 60 seconds, the format will be changed to hh:mm:ss and it can be in hh:mm:ss.fff format, when the step is less than 1 second.

NOTE: If the step is less than 900 seconds, the dropdown is hidden.

NOTE: changing the step to a larger duration can cause a new HasValue.ValueChangeEvent to be fired if some parts (eg. seconds) is discarded from the value.

Parameters:

step - the step to set, not null and should divide a day or an hour evenly

getStep

public Duration getStep()

Gets the step of the time picker.

Returns:

the step property from the picker, unit seconds
