undocumented layout managers

I found HorizBagLayout OrientableFlowLayout VariableGridLayout VerticalBagLayout in classes.zip (1.1.1)
but I cannot find any documentation.  Where is the API reference and how are these used?

You should look in the documentation under the package sun.awt

For more information, hit http://www.cdt.luth.se/java/doc/sun/shared/Package-sun.awt.html

You should find the regular documentation there.

Good luck...

I have found the same three APIs at a different location.  I was hoping for more of a how-to-use them answer.  I have found no documentation for OrientableLayout anywhere.

I have a feeling that these Layout Managers may not be implicitly intended for a programmer's use.  I've taken the first two Java programming courses from Sun and there was no documentation for them either.

If I was going to use VariableGridLayout, for instance, I would use it like I use GridLayout.  Without looking at the spec, I suspect that I will be allowed to set variable column widths.  I don't know if I'll be able to set variable row heights yet...  Here goes:

// Create a panel
Panel p = new Panel();
VariableGridLayout vgl = new VariableGridLayout( 1 , 2 , 5 , 5 ) );
p.setLayout( vgl );

// I'd add my components here
Label l = new Label( "Label" );
Button b = new Button( "Button" );

// Say you want to make the button twice as wide as the Label
vgl.setColFraction( 2, .67 );

// the above line says to me, make the second column 2/3 the
// width of the entire grid.

p.add( l );
p.add( b );
add( p );


Try the above and see if it works.  I've never used sun.awt as a package before and I'm still not certain if we're supposed to implicitly use it.

Good luck...
