Hello,
A few minor problems...
1. We are trying to save and retrieve boolean values in a properties file.
They are saved as strings. How do we read them back as booleans? (We can't
figure out how to use the getBoolean() method in Boolean which says it
reads a property name -- is this the same type of "property"?)
2. I am trying to scale a clone of a graphics object and insert it into the
original. (I want to preserve the original).
copyOfImage =3D (Image)offscreen.clone();
// I have also tried:
// mapscreen.copy(offscreen);
// However it returns nullPointerExceptions in runtime.
copyGraphics =3D copyOfImage.getGraphics();
copyOfGraphics.scale(.5f, .5f);
offGraphics.drawImage(copyOfImage,0, 0, null);
g.drawImage(offscreen, 0, 0, null);
It draws two identical images over each other at 100%. (I can see this by
setting off the images in the drawImage command.) However, if I scale
offGraphics then it works (but I get infinite scaling regression).
3. Dialog windows which worked in prebeta are acting funny in beta. They
appear briefly where they are supposed to and then relocate to the topleft
of the screen.
4. Again in beta, windows appear blue until resized by hand unless they
have a menubar. (This is more than just the blue-flash in the
Appletviewer...)(Running a Java application on a Sparc 20 with Solaris.)
Thanks,
Henry
