[platform-swt-dev] composite and H/V_SCROLL
|
Hello to all,
Hope someone of you can point me to the right direction.
I'm quite new to swt/jface and probably I'm doing wrong keeping thinking in
Swing.
What I'm trying to create is a tabbed pane with few editor components (using
a FormLayout) inside.
It looks ok but I'm not able to bring the form to be scrollable inside the
tab area.
Note: the tab viewport (sorry for the swing terminology) need to be
scrollable because one of the "editors" need to displays a lot of fields and
the only thing I can able to get is some fake scrollbar that doesn't scroll
the view port at all.
Here is the code I'm using.
java -classpath
c:\eclipse\swt\swt.jar;.;c:\eclipse\plugins\org.eclipse.jface_3.0.0\jface.jar;c:\eclipse\plugins\org.eclipse.core.runtime_3.0.1\runtime.jar
WidgetWindow
Thanks in advance.
