Implementations

impl QDate

pub fn add_months(&self, nmonths: i32) -> QDate

Returns a QDate object containing a date nmonths later than the date of this object (or earlier if nmonths is negative).

impl QDate

pub fn add_years(&self, nyears: i32) -> QDate

Returns a QDate object containing a date nyears later than the date of this object (or earlier if nyears is negative).

impl QDate

pub fn day(&self) -> i32

Returns the day of the month for this date.

impl QDate

pub fn day_of_week(&self) -> i32

Returns the weekday (1 = Monday to 7 = Sunday) for this date.

impl QDate

pub fn day_of_year(&self) -> i32

Returns the day of the year (1 for the first day) for this date.

impl QDate

pub fn days_in_monyth(&self) -> i32

Returns the number of days in the month for this date.

impl QDate

pub fn days_in_year(&self) -> i32

Returns the number of days in the year for this date.

impl QDate

pub fn is_null(&self) -> bool

Returns true if the date is null; otherwise returns false. A null date is invalid.

impl QDate

pub fn is_valid(&self) -> bool

Returns true if this date is valid; otherwise returns false.

impl QDate

pub fn month(&self) -> i32

Returns the month-number for the date.

Numbers the months of the year starting with 1 for the first

impl QDate

pub fn set_date(&mut self, y: i32, m: i32, d: i32) -> bool

Sets this to represent the date, in the Gregorian calendar, with the given year, month and day numbers. Returns true if the resulting date is valid, otherwise it sets this to represent an invalid date and returns false.

impl QDate

pub fn format_enum(&self, format: DateFormat) -> QString

Returns the time as a string. The format parameter determines the format of the string.

impl QDate

pub fn year(&self) -> i32

Returns the year of this date.

impl QDate

pub fn add_days(&self, ndays: i64) -> Self

Returns a QDate object containing a date ndays later than the date of this object (or earlier if ndays is negative).

Returns a null date if the current date is invalid or the new date is out of range.

pub fn current_date() -> Self

pub fn days_to(&self, date: Self) -> i64

Returns the number of days from this date to d (which is negative if d is earlier than this date).

Returns 0 if either date is invalid.

pub fn format(&self, format: &QString) -> QString

Returns the time as a string. The format parameter determines the format of the result string.

pub fn from_julian_day(jd: i64) -> Self

Converts the Julian day jd to a QDate.

pub fn from_string(string: &QString, format: &QString) -> Option<Self>

Returns the QTime represented by the string, using the format given, or None if the string cannot be parsed.

pub fn from_string_enum(string: &QString, format: DateFormat) -> Option<Self>

Returns the time represented in the string as a QTime using the format given, or None if this is not possible.

pub fn is_leap_year(year: i32) -> bool

Returns true if the specified year is a leap year in the Gregorian calendar; otherwise returns false.

pub fn new(y: i32, m: i32, d: i32) -> Self

Constructs a date with year y, month m and day d.

pub fn to_julian_day(&self) -> i64

Converts the date to a Julian day.

Trait Implementations

impl Clone for QDate

fn clone(&self) -> QDate

Returns a copy of the value.

Performs copy-assignment from source.

impl Debug for QDate

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl ExternType for QDate

type Id = (Q, D, a, t, e)

type Kind = Trivial

Either cxx::kind::Opaque or cxx::kind::Trivial.

impl Ord for QDate

fn cmp(&self, other: &QDate) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

impl PartialEq for QDate

fn eq(&self, other: &QDate) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
