Problem with Mozilla and Post Requests [message #437499]

I have successfully integrated Mozilla into my GTK/SWT application (by
the way; SWT is REALLY COOL! ).
My problem now is: I can tell the browser to open a certain URL but I
have no idea how to handle post requests and links.

Here is my code:

final Browser browser = new Browser(shell, SWT.NONE);
browser.setSize(640, 400);
browser.setUrl("http://80.78.255.19");

browser.addLocationListener(new LocationListener()
{
public void changed(LocationEvent event)
{
Elog.Elog("an event has occurred: " +
event.location);
Elog.Elog(" doit: " + event.doit);
Elog.Elog(" top: " + event.top);
/* location.setText(event.location); */
// browser.setUrl(event.location);
}
public void changing(LocationEvent event)
{
Elog.Elog("an event has occurred 2: " +
event.location);
Elog.Elog(" doit: " +
event.doit);
Elog.Elog(" top: " + event.top);
browser.setUrl(event.location);
}
});

Button quit = new Button(shell, SWT.PUSH);
quit.setSize(100, 50);
quit.setText("Quit");
quit.setLocation(50, 420);
quit.addSelectionListener(new SelectionAdapter()
{
public void widgetSelected(SelectionEvent e)
{
Elog.Elog("Calling quit");
shell.dispose();
}
});

The problem now is ...

An endless loop is started. As you can see the script function is said
to be the target of my click (I am hitting a link which is supposed to
call a JScript function).
How can I solve my problem and how can I make this (= navigation and
submit) work?

Best regards,

Hans

Hi Hans-Juergen,

> by the way SWT is REALLY COOL!
:-)

> My problem now is:
The Browser takes care of the links within itself. You usually don't have
to worry about the LocationListener. In your code below, if I remove the
LocationListener code, the app seems to correctly connect to the website.

LocationListener is typically used in two situations.
1. To update the Location text entry in a browser app - using
LocationListener.changed when event.top is true
2. To filter/redirect to another browser/trigger an SWT UI action in
response to a URL navigation request. Use LocationListener.changing.
Determine if Event.location refers to the URL pattern you are interested
in. Set Event.doit to false to block the current request from being
further processed. And do your own action. If you do nothing, the URL will
be loaded (event.doit should be true by default).

Hope this helps,
Chris
