Pressed icon behaviour

[Dirk Bruere at NeoPax]

Slight oddity.
I have an app with icon buttons.
On one machine with a touch screen the icons move slightly when pressed.
On others that doesn't happen.
What governs that behaviour? AFAIK all machines are running the same JRE

It sounds like the platform shows button "press" behavior by shifting the
icon. Are these JButtons or AWT buttons? (I'm guessing AWT with heavyweight
delegate) Which platforms / jvm?

Swing.
Not sure what JVM. All I know is that I keep the Java stuff up to date
from Sun (as of last week). They are both running on a Windows XP system.

Any way to force that key movement behaviour? - it looks good.

You might look at SwingSet2, an example application that is often
included in the SDK. It allows one to see how standard Swing components
look with various Look & Feel settings. A changing bevel highlight
causes apparent motion in the Java (Metal) L&F.

You can private many different icons to represent the state. This
effect would be independent of any wiggling a particular JVM/Swing
implementation does. You could simulate the effect with an image a few
pixels to large and offsetting the image left and right for pressed
and plain versions.

Yes - I guessed that when reading the button menus.
Just wondered whether there was a simpler method by ticking a box somewhere.

See if it is a side effect of the look and feel. You can force a
particular look and feel.

LAFs have great latitude in how the various button states look by
default.

Let me try that again.


You can PROVIDE many different icons to represent the state. This
effect would be independent of any wiggling a particular JVM/Swing
implementation or L&F does. You could simulate the effect with an
image a few pixels TOO large, and offsetting the image left and right
for pressed and plain versions.
