Close and or refresh Browser Window
Mar 7th, 2009, 5:19pm  
Hi.. I need to know how to do 2 things:

In my processing script, I trigger the opening of a browser window using a sensor using the following command:

link ("http://www.somesite.com/php/openthispage.php");

the next time I trigger the sensor, it spawns the opening of another browser window.

How can I direct the process to look if the browser window exists, and if so, just resubmit/refresh it?

Similarly, how can direct the closing of a browser window that was opened?

I don't think you can do what you want, unless, perhaps, you target a precise browser on a given system. Doing that in a portable way is much trickier: it depends on default browser of the user, you have to know which window you opened (to avoid closing a different one of the same browser), etc.

Well, from what I can see, the link command doesn't allow me to assign a window handle.

Should I/can I use a java method to open / close windows?

Does anyone have an example?

I mean that for closing a window opened by the link command.
Unless you can do a window manager in Java (again, that's strongly system dependent, I think).
I can be wrong, of course. (By "not possible" I mean "quite hard".)

Perhaps by explaining what you want to do at a broader level (why open this page in browser), we can help finding workarounds.

I think if you use the 2nd form of the link command, and use the same "target" each time then it will open the URL in the previously opened window/tab

e.g.
Code:
link("http://www.foo.com","MyWindow");

Thanks for answering...

I'm using Windows2003 + Explorer 6 or the latest Firefox.
I don't mind "hardcoding" a solution for only this platform. THis is for my use anyway.

Here is the syntax I am using. When activated, it continues to spawn windows...

link("http://mysite.com/myphpprogram.php", "MyWindow" );

I'm amenable to any solution...

I guess the target parameter works only when the sketch is run as an applet, in a browser.
Here, you can communicate with JavaScript (in the hosting Web page), so you can manipulate windows like JS does: open new, update, close... as long as the browser still allow it, of course.

Ok... I hate to say this, but how do you do that? Do you have a snippet of code?

Processing PDE has a menu for that: File > Export.
It will generate a JAR file and an HTML file embedding the applet.
