Re: [platform-swt-dev] eclipse Linux 390 --Error: Widget has zero width and/or height
|
Veronika,
Thanks, I will try this sample app.... but please realize that I had to
re-build openmotif 2.1 on Linux/390 ...what is shipped with eclipse is an
Intel version....
A major difference between 390 and i86 is big endian vs little endian .
(aside from the instruction set architecture itself).... so re-compile is
always necessary at
a minimum. I am running with the November 7 official version 1.0
........... unfortunately I only have .class files for the failing routine
........ the .java is not shipped.

Motif will not allow a widget to have zero width or height. As a work
around, we make sure the widget size is greater than (0, 0). This is
already done in the SWT code so I am not quite sure why you are seeing a
problem.
Which eclipse build are you running?
Are you using the open motif libraries shipped with Eclipse? (see
libXm.so.2.1 in the root of the eclipse install - make sure your
LD_LIBRARY_PATH points here rather than to the /usr/lib location).
Can you run this simple application - if not, comment out the first
c.setBounds call and uncomment the second c.setBounds call - does it work
now? Note, to run this application, the SWT libraries (see
eclipse/plugins/ws/motif) and the open motif libraries shipped with eclipse
(see eclipse/libXm.so.2.1) must be on your LD_LIBRARY_PATH.
import org.eclipse.swt.*;
import org.eclipse.swt.widgets.*;
public class SWTTest {
public static void main (String [] args) {
Display display = new Display ();
Shell shell = new Shell (display);
Composite c = new Composite(shell, SWT.BORDER);
c.setBounds(-200, -200, 0, 0);
//c.setBounds(10, 10, 100, 100);
shell.open ();
while (!shell.isDisposed ()) {
if (!display.readAndDispatch ()) display.sleep ();
}
display.dispose ();
}
}

Please respond to --Error: Widget has zero width and/or
platform-swt-dev height
Anyone have any idea what this could be ?? We're into a lot of "new" code
on Linux/390 --- including openmotif 2.1, java 1.3.0+, and SuSE 7.2 .....
so I built
eclipse against all of this .... it gets the subject message and hangs with
default workbench plugin ........ any environmentals I should be setting??
Looking at just init of swt stuff ............ (all prior init seems to be
ok ...except see JNI warnings at bottom of note)
Thanks, Steve

BTW, I get these messages during init in my verbose output ....... how do I
