BoxLayout making component too big

Thread view:

Nomak - 26 Apr 2005 10:29 GMT

Hello,

if i put some component in a FlowLayout, they have a "clever" size. But i need to have them verticaly, so i use a BoxLayout(Y_AXIS). But the layout make the components big to fill all the panel space (in fact the 2 radio button are ok, but the combo box has a big height).

How can i prevent that? I reaaly juste need a flowlayout but vertical. If i must say wich size (preferred, min, max) to use, it's simpler to use a "null" layout.

Thx for your help

See "How to Use BoxLayout" in the Java Tutorial. Check out the part on
rigid areas, glue, and custom fillers.

well, i did, but when running the demo associated with this:

http://java.sun.com/docs/books/tutorial/uiswing/layout/example-1dot4/BorderLayou
tDemo.java

the buttons have a "good" size, they don't fill all the panel.

By looking at the code, you can see that there isn't any Box.Filler or related.

So why is it working?

Since it is using BorderLayout, not BoxLayout?

A BoxLayout will *try* to fill the container that it lays out, but it will
also respect the preferred, minimum, and maximum sizes of the components
in the container. If they do not fill the container at their maximum
sizes, it will leave the extra space at the end.

I have set the max size for my components in a vertiaclBox and they are all
centered in the damn window.

Why?

I would guess you have a bug in your code. I have no idea how to figure
out exactly what the problem is without seeing the code. Please post a
runnable example of the problem.

My advice is use TableLayout

http://www.clearthought.info/software/TableLayout/

http://java.sun.com/products/jfc/tsc/articles/tablelayout/

This is the most flexible and easy to use too.

I used to use BoxLayout a lot until I found out about TableLayout.
