real-time resizing?

Thread view:

Jim Pete - 20 Nov 2003 12:29 GMT

I have a swing application that is made up of only one textarea that takes
the size of the window. When I resize it using the window's border, it does
not resize in real-time. It only resizes when I release my finger from the
mouse. Im using BorderLayout for this app.

Also, when I use the mouseDragged event, it does not get called when I
resize the borders.

Can anyone help me out?

Thanks

    The window resizing events come from your operating system.
    Try adding a component listener to your JFrame (You are using
    Jframe, right?) and print some debugging info every time you
    receive a componentResized event. My bet is that you only
    receive one event (when you release the mouse button).

    It is not a mouse drag event. Try listening for a "mouseExited"
    event and you'll notice you get one before you get a chance to
    resize the window.

    You need to go to a newsgroup that handles questions about your
    specific operating environment. The Java virtual machine can not
    do anything if it does not receive events from the operating
    system.

    PS. In Fedora Core 1 with Metacity window manager Swing windows
    are resized in real time. Maybe you should try it. :-)

Hi,

Thanks for responding. Yes, I am using JFrame. You are saying that resizing
is an operating system issue... hmmm.... I am on Windows. I don't think the
windows newsgroups will respond to any swing-java issues... they'll
recommend I go to a java newsgroup... hehehe.. its never ending loop..

There must be some workaround to make this work on Windows....

first call Frame.setResizeable(false);
then write your own MouseListener and MouseMotionListener to handle resize.

it worked with JWindow, why not with JFrame?

this works only with 1.4 and later and is platform-specific issue!

So what :-)

1.4 is pretty much the standard in the meantime, especially for any new
development there is hardly no reason to use something else.

And it's only so far platform specific that on those platforms where the
user can control this feature, the user setting will override this featuer,
which is perfectly accetable I think.
