java.awt.Frame and System.currentTimeMillis()
I have put new b86 builds of pMEA on my website
I have changed the way how AWT Frames are created. They are now always full
screen without covering the top system bar. I actually ignore the size of the
frame that the user may have set. I could also cover the top system bar so
that you can no longer access the application menu or an application
switcher. I did not do this because if your application does not close
properly, you may have no other choice then to reset the PDA to terminate the
application. I also removed the decoration of the AWT Frame to save some
space and be more consistent with other native Windows Mobile applications.
Of course, this also means that for a WinCE platform with an 800x600 display,
the full screen would be used for any AWT application.
I changed the implementation of currentTimeMillis by relying both on the
GetSystemTime and GetTickCount to get a finer granularity than seconds. The
current implementation should be able to compute the time correctly after a
suspend and resume. Like I stated in a previous mail, the current time in
milliseconds is based on the GetTickCount value which returns the number of
msecs since device startup. To get the number of msecs since 1/1/70 I have to
add a delta. This delta remains fixed as long as you do not suspend and
resume a running application. If after a suspend and resume the difference
with the system time is more than 1 second, I recompute the delta.
I also received several reports of people that experienced an exception (error
code c0000005) when using a virtual keyboard and filling in an AWT text
field. It appears to only occur on Windows Mobile 6 platforms and I have been
able to trigger the exception with builds of a more than a year old. I
currently have no fix for this problem yet as I do not know what is causing
this behavior. Nonetheless, those who reported on the java.awt.Frame and
System.currentTimeMillis issues are free to test the new builds and provide
feedback on the forum.
