Detailed Description

The Q3TimeEdit class provides a time editor.

Q3TimeEdit allows the user to edit times by using the keyboard or the arrow keys to increase/decrease time values. The arrow keys can be used to move from section to section within the Q3TimeEdit box. The user can automatically be moved to the next section once they complete a section using setAutoAdvance(). Times appear in hour, minute, second order. It is recommended that the Q3TimeEdit is initialised with a time, e.g.

 QTime timeNow = QTime::currentTime();
 Q3TimeEdit *timeEdit = new Q3TimeEdit(timeNow, this);
 timeEdit->setRange(timeNow, timeNow.addSecs(60 * 60));

Here we've created a Q3TimeEdit widget set to the current time. We've also set the minimum value to the current time and the maximum time to one hour from now.

The maximum and minimum values for a time value in the time editor default to the maximum and minimum values for a QTime. You can change this by calling setMinValue(), setMaxValue() or setRange().

Terminology: A QTimeWidget consists of three sections, one each for the hour, minute and second. You can change the separator character using setSeparator(), by default the separator is read from the system's settings.

Member Type Documentation

enum Q3TimeEdit::Display

This enum defines the sections that comprise a time

Q3TimeEdit::Hours0x01The hours section
Q3TimeEdit::Minutes0x02The minutes section
Q3TimeEdit::Seconds0x04The seconds section
Q3TimeEdit::AMPM0x10The AM/PM section

The values can be or'ed together to show any combination.

Property Documentation

autoAdvance : bool

This property holds whether the editor automatically advances to the next section.

If autoAdvance is true, the editor will automatically advance focus to the next time section if a user has completed a section. The default is false.

Access functions:

display : Display

This property holds the sections that are displayed in the time edit.

The value can be any combination of the values in the Display enum. By default, the widget displays hours, minutes and seconds.

Access functions:

maxValue : QTime

This property holds the maximum time value.

Setting the maximum time value is equivalent to calling Q3TimeEdit::setRange(minValue(), t), where t is the maximum time. The default maximum time is 23:59:59.

Access functions:

See also minValue and setRange().

minValue : QTime

This property holds the minimum time value.

Setting the minimum time value is equivalent to calling Q3TimeEdit::setRange(t, maxValue()), where t is the minimum time. The default minimum time is 00:00:00.

Access functions:

See also maxValue and setRange().

time : QTime

This property holds the editor's time value.

When changing the time property, if the time is less than minValue(), or is greater than maxValue(), nothing happens.

Member Function Documentation

Q3TimeEdit::Q3TimeEdit ( QWidget * parent = 0, const char * name = 0 )

Constructs an empty time edit with parent parent and called name.

Q3TimeEdit::Q3TimeEdit ( const QTime & time, QWidget * parent = 0, const char * name = 0 )

Constructs a time edit with the initial time value, time, parent parent and called name.

Q3TimeEdit::~Q3TimeEdit ()

Destroys the object and frees any allocated resources.

QString Q3TimeEdit::sectionFormattedText ( int sec )   [virtual protected]

Returns the formatted number for section sec. This will correspond to either the hour, minute or second section, depending on sec.

QString Q3TimeEdit::separator () const

Returns the editor's separator.

See also setSeparator().

void Q3TimeEdit::setHour ( int h )   [virtual protected]

Sets the hour to h, which must be a valid hour, i.e. in the range 0..24.

void Q3TimeEdit::setMinute ( int m )   [virtual protected]

Sets the minute to m, which must be a valid minute, i.e. in the range 0..59.

void Q3TimeEdit::setRange ( const QTime & min, const QTime & max )   [virtual]

Sets the valid input range for the editor to be from min to max inclusive. If min is invalid no minimum time is set. Similarly, if max is invalid no maximum time is set.

void Q3TimeEdit::setSecond ( int s )   [virtual protected]

Sets the second to s, which must be a valid second, i.e. in the range 0..59.

void Q3TimeEdit::setSeparator ( const QString & s )   [virtual]

Sets the separator to s. Note that currently only the first character of s is used.

See also separator().

void Q3TimeEdit::valueChanged ( const QTime & time )   [signal]

This signal is emitted whenever the editor's value changes. The time parameter is the new value.
