/**
|
|
This class defines methods for streaming widget data.
|
|
|
|
For each widget type rules are defined telling which attributes should be
|
|
streamed. If you need to stream other attributes or to avoid streaming
|
|
certain attributes, then this may be obtained by editing the property
|
|
map, which is obtained by calling @ref propertyMap. For further control
|
|
inherit from this class and override @ref toStream and @ref fromStream.
|
|
|
|
The following example shows how you can avoid streaming
|
|
<tt>numDigits</tt> for a TQLCDNumber. The same approach applies if you
|
|
want to add extra properties to be streamed.
|
|
<pre>
|
|
KWidgetStreamer streamer;
|
|
KWidgetStreamer::PropertyMap& map = streamer.propertyMap();
|
|
KWidgetStreamer::PropertyList& list = *map.find(TQLCDNUMBER_OBJECT_NAME_STRING);
|
|
list.remove("numDigits");
|
|
</pre>
