Question

I have the following,

GridLayout layout = new GridLayout(4, 0);

In the event that I have 5 items, this will create 2 columns, where the first contains 3 rows and the second contains 2 rows. This is not what I want, nor is this what I expected. I expected the first column to contain 4 rows and the second column to contain 1 row.

Why isn’t this layout manager respecting the number of rows I want per column? Or better yet, how do I make this layout manager respect this?

Answer 1

The result seems expected: “Specifying the number of columns affects the layout only when the number of rows is set to zero.”

You can get the desired effect using JList, as shown here.

private static final int N = 5;
...
list.setLayoutOrientation(JList.VERTICAL_WRAP);
list.setVisibleRowCount(N - 1);
