<div class="section"><p>A <a href="javadoc/com/ibm/as400/vaccess/VPrinters.html#NAVBAR_TOP"> VPrinters</a> object is a resource that represents
|
||
|
|
a list of printers for use in <a href="vpanes.htm#vpanes">AS400Panes</a>.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><p>To use a VPrinters object, set the system property. Set this property
|
||
|
|
by using a constructor or through the <a href="javadoc/com/ibm/as400/vaccess/VPrinters.html#SETSYSTEM(COM.IBM.AS400.ACCESS.AS400)"> setSystem()</a> method. The VPrinters object
|
||
|
|
is then "plugged" into the AS400Pane as the root, using the pane's constructor
|
||
|
|
or setRoot() method.</p>
|

</div>
|
||
|
|
<div class="section"><p>A VPrinters object has another useful property for defining the
|
||
|
|
set of printers that is presented in AS400Panes. Use <a href="javadoc/com/ibm/as400/vaccess/VPrinters.html#SETPRINTERFILTER(JAVA.LANG.STRING)"> setPrinterFilter()</a> to specify a filter
|
||
|
|
that defines which printers should appear.</p>

</div>

<div class="section"><p>When AS400Pane and VPrinters objects are created, they are initialized

to a default state. The list of printers has not been loaded. To load the

contents, the caller must explicitly call the load() method on either object.</p>

</div>
|
||
|
|
<div class="section"><p>At run-time, a user can perform actions on any printer list or
|
||
|
|
printer by right-clicking it to display the context menu. The printer list
|
||
|
|
context menu can include an item called <strong>Properties</strong> that allows the
|
||
|
|
user to set the printer filter property, which can change the contents of
|
||
|
|
the list.</p>
|

</div>

<div class="section"><p>The printer context menu can include the following items:</p>

</div>

<div class="section"><ul><li><strong>Hold</strong> - holds the printer</li>
|
||
|
|
<li><strong>Release</strong> - releases the printer</li>
|

|
|
<li><strong>Start</strong> - starts the printer</li>
|
||
|
|
<li><strong>Stop</strong> - stops the printer</li>
|
||
|
|
<li><strong>Make available</strong> - makes the printer available</li>
|
||
|
|
<li><strong>Make unavailable</strong> - makes the printer unavailable</li>
|
||
|
|
<li><strong>Properties</strong> - displays properties of the printer and allows the

user to set filters</li>

</div>

addition, the caller can prevent the user from performing actions by using

the setAllowActions() method on the pane.</p>
