its overridden by your layout hints. use LAYOUT_FIX_X|LAYOUT_FIX_Y if
you want to position widgets explicitly

the "numColumns" attribute of textfield overwrites the "width". same
here. use LAYOUT_FIX_WIDTH to make width effective instead of
numColumns.

not yet. what you would want to read is what Mike Parr is currently
writing. a very detailed introduction to foxGUIb and fxruby. however
it is not finished yet. in the meanwhile you could download foxGUIb
(or even better check it's latest version out of CVS).
foxGUIb let's you play around with most of the parameters of most
common widgets and layout containers. it is a good start for learning
fxruby. check it out at: http://rubyforge.org/fox-tool
