</R>Purpose<!R>
The Cdk calendar widget is a simple little widget which allows a user to
play with a calendar.
</R>Construction Options<!R>
The calendar widget is defined using the following syntax. The variable
</B>$calendarObject<!B> contains the reference to the entry object.
<C></B>$calendarObject = new Cdk::Calendar ( options );
The options are defined in the following table.
</U>Option Default Value Type Purpose<!U>
Day The current day Scalar The day of the calendar.
of the month.
Month The current month Scalar The month of the calendar.
Year The current year Scalar The year of the calendar.
Dattrib Normal Scalar The attribute of the days.
Mattrib Normal Scalar The attribute of the month name.
Yattrib Normal Scalar The attribute of the year.
Highlight Reverse Scalar The highlight attribute of the cursor.
Filler . Scalar The default field character.
Xpos Center Scalar This is the position of the window on the X axis.
Ypos Center Scalar This is the position of the window on the Y axis.
Box True Scalar This Boolean states whether the dialog box will have a box drawn around it.
Shadow False Scalar This Boolean states whether the dialog box will have a shadow on the box.
</R>Available Methods<!R>
</B>activate<!B>
Activation of an object means to make the object available for use. The
following example demonstrates how to activate a entry widget.
<C></B>($day, $month, $year) = $calendarObject->activate ();
The variables </B>$day<!B>, </B>$month<!B>, </B>$year<!B> is the date
of the calendar when it exited.
</B>inject<!B>
This function injects a single character into the widget. The following
examples demonstrates how to call the inject method.
<C></B>$calendarObject->inject ( options );
The options are defined in the following table.
</U>Option Default Value Type Purpose<!U>
Shadow Required Scalar The character to inject into the widget.
If you are injecting a special character into the widget, then you can
use a pre-defined value to represent the key.

<C><#VL>Escape <#VL>KEY_ESC <#VL>
<C><#LL><#HL(11)><#BT><#HL(14)><#LR>
</B>setDate<!B>
Sets the current date of the calendar field.
<C></B>$calendarObject->setDate ( options );
The options are defined in the following table.
</U>Option Default Value Type Purpose<!U>
Day Required Scalar The day of the calendar.
Month Required Scalar The month of the calendar.
Year Required Scalar The year of the calendar.
</B>bind<!B>
The bind method binds keys to events. The binding is specific to the individual
objects. The following example demonstrates how to call the bind method.
<C></B>$calendarObject->bind ( options );
The options are defined in the following table.
</U>Option Default Value Type Purpose<!U>
Key Required Scalar This is the character to bind the event to.
Function Required Scalar This is the name of the callback function.
</B>preProcess<!B>
The </B>preProcess<!B> function sets a process to be run before the key entered
is processed. If this function returns a value of 0, then the key injected
into the widget will not be processed; otherwise the character will be
processed as normal. The following example demonstrates how to call the
preProcess method.
<C></B>$calendarObject->preProcess ( options );
The options are defined in the following table.
</U>Option Default Value Type Purpose<!U>
Function Required Scalar This is the name of the
callback function.
To create a pre-process callback the following code segment demonstrates
how to do it properly.
fulldemo/help/calendar.help view on Meta::CPAN
If the pre-process function returns a value of 0 the key hit will
not be injected into the widget. This allows the programmer to
selectively pick which characters will or will not get injected
into the widget.
The </B>postProcess<!B> function sets a process to be run before the key entered
is processed. If this function returns a value of 0, then the key injected
into the widget will not be processed; otherwise the character will be
processed as normal. The following example demonstrates how to call the
postProcess method.
<C></B>$calendarObject->postProcess ( options );
The options are defined in the following table.
</U>Option Default Value Type Purpose<!U>
Function Required Scalar This is the name of the
callback function.
To create a post-process callback the following code segment demonstrates
how to do it properly.

<C><#LL><#HL(11)><#BT><#HL(14)><#LR>
</B>draw<!B>
This method draws the object on the screen. The following example demonstrates
how to call the draw method.
<C></B>$calendarObject->draw ( options );
The options are defined in the following table.
</U>Option Default Value Type Purpose<!U>
Box True Scalar Draws the window with a box around it.
</B>erase<!B>
This method removes the object from the screen. This does </B/U>NOT<!B!U>
destroy the object. The following example demonstrates how to call the erase
method.
<C></B>$calendarObject->erase ();
</B>raise<!B>
The raise method raises the widget to the top of the screen. This means if there
were any widgets obscuring part of the view, raising the object would bring the
complete object into view. The following example demonstrates how to call the
raise method.
<C></B>$calendarObject->raise();
</B>lower<!B>
The lower method lowers the object so it doesn't obscure the view of any other
objects. The following example demonstrates how to call the lower method.
<C></B>$calendarObject->lower();
</B>register<!B>
The register method registers the object to the default screen. This does </R>NOT<!R>
have to be called since the objects are registered automatically. This method
should be called if the </B>unregister<!B> method was called. The following
example demonstrates how to call the register method.
<C></B>$calendarObject->register();
</B>unregister<!B>
The unregister method should be called when a widget, which is part of the
default screen, needs to be taken away temporarily. This does not delete or free
the object, it just unmaps it from any future screen refreshes. The object can
be registered by calling the </B>register<!B> method. The following example
demonstrates how to call the unregister method.
<C></B>$calendarObject->unregister();
</B>getwin<!B>
This method returns a pointer to the window of the object. Not much use for this
yet. It will be useful in the future when the drawing methods are added. The
following example demonstrates how to call the getwin method.
<C></B>$calendarObject->getwin();
</R>Default Key Bindings<!R>
Since this widget is 'driven' by the entry field, the default key bindings
of the entry field apply to this widget. There are however extra bindings
which have been applied. They are as follows:
</U>Key Action<!U>
TAB Tries to complete the word in the entry field.
Key Up Scrolls the list one item backward.
Page Up Scrolls the list one page backward.
fulldemo/help/calendar.help view on Meta::CPAN
Return Returns what is currently displayed in the entry field.
Escape Exits the widget and returns undef.
</R>Tips & Tricks<!R>
None.
</R>Physical Restrictions<!R>
Same as the scrolling list.
</R>Example Use Of The Widget<!R>
