interface XDispatch |
|
- Description
- serves state information of objects which can be connected to
controls (e.g. toolbox controls).
Each state change is to be broadcasted to all registered
status listeners. The first notification should be performed
synchronously from addStatusListener();
if not, controls may flicker. State listener must be aware of this
synchronous notification.
The state consists of enabled/disabled and a short descriptive text
of the function (e.g. "undo insert character"). It is to be broadcasted
whenever this state changes or the control should re-get the value
for the URL it is connected to. Additionally, a context-switch-event
is to be broadcasted whenever the object may be out of scope,
to force the state listener to requery the XDispatch.

Arguments ); |
- Description
- dispatches (executes) an URL asynchronously.
It is only allowed to dispatch URLs for which this XDispatch
was explicitly queried. Additional arguments ("'#..." or "?...") are allowed.
- Parameter URL
- fully parsed URL describing the feature which should be dispatched (=executed)
- Parameter Arguments
- optional arguments for this request.
They depend on the real implementation of the dispatch object.
- Example
// some code for a click-handler (Java)
void myOnClick(String sURL,String sTargetFrame,com.sun.star.beans.PropertyValue[] lArguments)
{
com.sun.star.util.URL[] aURL = new com.sun.star.util.URL[1];
aURL[0] = new com.sun.star.util.URL();
aURL[0].Complete = sURL;
com.sun.star.util.XURLTransformer xParser = (com.sun.star.util.XURLTransformer)UnoRuntime.queryInterface(
com.sun.star.util.XURLTransformer.class,
mxServiceManager.createInstance("com.sun.star.util.URLTransformer"));
xParser.parseStrict(aURL);
com.sun.star.frame.XDispatch xDispatcher = mxFrame.queryDispatch(aURL[0], sTargetFrame, com.sun.star.frame.FrameSearchFlag.GLOBAL);
if(xDispatcher!=null)
xDispatcher.dispatch(aURL[0], lArguments);
}

addStatusListener
- Description
- registers a listener of a control for a specific URL
at this object to receive status events.

was explicitly queried. Additional arguments ("#..." or "?...") will be ignored.
Note: Notifications can't be guaranteed! This will be a part of interface XNotifyingDispatch.
- Parameter Control
- listener that wishes to be informed
- Parameter URL
- the URL (without additional arguments) the listener wishes to be registered for.
A listener can be registered for more than one URL at the same time.

- Parameter Control
- listener that wishes to be unregistered
- Parameter URL
