Hi!
I noticed the following problems in recent releases of Linux jdk 1.1.6.
RedHat 5.0
glibc version of jdk, no dynamic Motif
Window Manager: fvwm2, icewm (http://ixtas.fri.uni-lj.si/~markom/icewm/)
Port#1: java version "Linux_JDK_1.1.6_v1"
Port#2: java version
"[EMAIL PROTECTED]:05/29/98-18:52"
(RH5.0_jdk1.1.6v1.2)
The first program (noresize.java) has two testcases. The first one
involves toggling setResizable. The second one moves the window 1 pixel
to the right/bottom.
Problem #1: Window jumps upwards for ~titlebar size the first time
Move+1+1
button is pressed. It works fine afterwards. This is repeatable both
with fvwm2 and icewm. (I also tried wmaker, but oddly enough the window
moves in the wrong direction there -- it seems to be wmaker bug).
Repeatable under Port#1 and Port#2
Problem #2: setResixable(false) disables minimize function too. It
probably
should not do that.
Repeatable under Port#1 and Port#2
Problem #3: toggling setResizable(...) repeatedly maps and unmaps the
window.
This is very ugly and probably unnecessary. It should be enough just to
update
the MWM and other hints. Mapping/unmapping the frame also loses all the
WM state and this is bad.
There is also a possible (?) bug in mapping/unmapping the window.
Previous
versions of icewm had a problem where window would not come up again.
This
was caused by the fact that window was reparented back to the root and
the
map request was sent (before even reparented) to the parent frame (now
destroyed). Since icewm is more OO than other WMs this caused the map
request being ignored. I have made a workaround for this, but I'd prefer
to remove it someday.
Repeatable under Port#1 and Port#2
Problem #4: application that sets setResizable(false) has the default
size
wrong (min/max sizes are OK). Here is the output of xprop:
program specified size: 513 by 291
program specified minimum size: 512 by 291
program specified maximum size: 512 by 291
A cutdown testcase is offone.java (It needs swing). Output of xprop for
it is:
program specified size: 101 by 135
program specified minimum size: 100 by 135
program specified maximum size: 100 by 135
The min,max sizes look correct but the default size is not within the
limits.
Repeatable under Port#2. It also occured in some previous versions of
Port#1,
but seems to be OK now.
