Displaying dynamically changing image: a problem with JLabel.
Hello! I use NetBeans 5.5 and I develop my GUI with Matisse. I'm rather a beginner in developing GUIs with this editor...
I'd like to display a dynamically changing image. The idea is: GUI shows the image, that is modified as some computations run in a different thread. App will be run on a single machine.
I'm trying to display the image as a label's icon. The problem is that my app's frame can be resized - and when it is, the label also resizes. When the label is resized, the image should also be resized - the image should always be of the same size as the label. The problem? I noticed, that it works only when I make my app's bigger. When I try to lower its dimensions, the label's dimensions remain the same. Why the label don't make its size smaller?
My code works as follows: when app's main frame is resize, the panel (the one, that the label is placed in) is also resized. And, since the label is in the panel, it (should) also be resized. So I wrote all the resize-events handlers (therefore I know that the resize event is sent when my app's frame is resized, and when the panel is resized - but the label is resized *only* when it grows bigger). In this methods I modify the image displayed in the label (I resize the image).
Or, perhaps, there is some other way to show a (dynamically changing) image with Swing... I chose JLabel, because I didn't want to write my own JComponent. JLabel can display image and that is all I need. The problem is: when the label grows bigger, I create a new, bigger image (icon). Why my label don't get smaller (the resize event isn't even sent)?
