[java-gnome-hackers] String encoding | showAll() | ButtonBox example

[Mark H. <mh...@ti...>]

hi,
  I've been working on an example app for the ButtonBoxes:
/src/examples/gtk/buttonbox/ButtonBoxes.java
(I have implemented gtk Frame btw)

The main problem seems to be with string encodings.=20
The button box example gives the warnings:
** (java-gnome:14365): WARNING **: Invalid UTF8 string passed to
pango_layout_set_text()

In my code, I have been using String.getBytes() with no encoding
argument. I guess this is wrong. I have tried a few examples and read
through the gtk docs, but have been unable to determine what should be
passed to the getBytes method.=20

This seems to affect all classes which pass Strings to native methods.

All widgets seem to require either implicit show() calls or calls to
showAll() of their direct parent. This seems strange, IMHO.

I'll take a look at it this evening and see if I can uncover
the root of the problem.

This is strange but not something we can get around.  It is a
requirement of the GTK libs.
