Detailed Description

Provides a widget for calendar date input. A date selection widget.

Different from the previous versions, it now emits two types of signals, either dateSelected() or dateEntered() (see documentation for both signals).

A line edit has been added in the newer versions to allow the user to select a date directly by entering numbers like 19990101 or 990101.

Constructor & Destructor Documentation

KDatePicker::KDatePicker const QString calType = "gregorian",
QWidget parent = 0,
QDate  = QDate::currentDate(),
const char *  name = 0
 

The usual constructor.

The given date will be displayed initially.

Definition at line 42 of file mkdatepicker.cpp.

References dateChanged(), line, monthBackward, monthForward, selectMonth, selectYear, setDate(), setFontSize(), QLineEdit::setValidator(), table, tableClicked(), val, yearBackward, and yearForward.

KDatePicker::~KDatePicker  )  [virtual]
 

The destructor.

Definition at line 83 of file mkdatepicker.cpp.


Member Function Documentation

QSize KDatePicker::sizeHint  )  const
 

The size hint for date pickers.

The size hint recommends the minimum size of the widget so that all elements may be placed without clipping. This sometimes looks ugly, so when using the size hint, try adding 28 to each of the reported numbers of pixels.

Definition at line 393 of file mkdatepicker.cpp.

References QSize::height(), line, maxMonthRect, monthBackward, monthForward, selectMonth, selectYear, QLineEdit::sizeHint(), QWidget::sizeHint(), KDateTable::sizeHint(), table, QSize::width(), yearBackward, and yearForward.

bool KDatePicker::setDate const QDate  ) 
 

Sets the date.

Returns:
false and does not change anything if the date given is invalid.

Definition at line 165 of file mkdatepicker.cpp.

References KCalendarSystem::formatDate(), QDate::isValid(), line, KCalendarSystem::monthName(), selectMonth, selectYear, KDateTable::setDate(), QString::setNum(), QLineEdit::setText(), table, and KCalendarSystem::year().

const QDate & KDatePicker::getDate  )  const
 

Returns the selected date.

This class or method is obsolete, it is provided for compatibility only.

Definition at line 153 of file mkdatepicker.cpp.

References KDateTable::getDate(), and table.

const QDate & KDatePicker::date  )  const
 

Returns:
the selected date.

References KDateTable::getDate(), and table.

void KDatePicker::setEnabled bool   ) 
 

Enables or disables the widget.

Definition at line 361 of file mkdatepicker.cpp.

References line, monthBackward, monthForward, selectMonth, selectYear, QWidget::setEnabled(), table, yearBackward, and yearForward.

void KDatePicker::setFontSize int   ) 
 

Sets the font size of the widgets elements.

Definition at line 426 of file mkdatepicker.cpp.

References QFontMetrics::boundingRect(), QWidget::font(), QSize::height(), QRect::height(), maxMonthRect, KCalendarSystem::monthName(), selectMonth, selectYear, KDateTable::setFontSize(), QSize::setHeight(), QFont::setPointSize(), QSize::setWidth(), table, QSize::width(), and QRect::width().

int KDatePicker::fontSize  )  const [inline]
 

Returns the font size of the widget elements.

void KDatePicker::resizeEvent QResizeEvent  )  [protected]
 

the resize event

Reimplemented from QFrame.

Definition at line 88 of file mkdatepicker.cpp.

References line, monthBackward, monthForward, selectMonth, selectYear, QWidget::setGeometry(), QSize::setWidth(), QLineEdit::sizeHint(), QWidget::sizeHint(), table, QSize::width(), yearBackward, and yearForward.

void KDatePicker::dateChanged QDate   )  [signal]
 

This signal is emitted each time the selected date is changed.

Usually, this does not mean that the date has been entered, since the date also changes, for example, when another month is selected.

dateSelected

void KDatePicker::dateSelected QDate   )  [signal]
 

This signal is emitted each time a day has been selected by clicking on the table (hitting a day in the current month).

It has the same meaning as dateSelected() in older versions of KDatePicker.

void KDatePicker::dateEntered QDate   )  [signal]
 

This signal is emitted when enter is pressed and a VALID date has been entered before into the line edit.

Connect to both dateEntered() and dateSelected() to receive all events where the user really enters a date.

void KDatePicker::tableClicked  )  [signal]
 

This signal is emitted when the day has been selected by clicking on it in the table.
