BoxLayout won't respect JScrollPane/JTextPane sizes?
[nobr]Hi all. I'm in Swing Layout Hell. I'm trying to set up a JPanel that looks and acts like this:
+-++
| label1: | |
| | |
+-++
| label2: | |
| | |
+-++
| label3: |this column expands -->|
+-++
| label4: | |
+-++
| label5: | |
| | |
| | |
| | |
| |this row expands -+ |
| |V |
+-++
All the cells have borders around them.
The idea is that when you resize the panel, only the last row and the last column expands. Label1 and Label2 are 2-line multiline HTML labels. Labels 3, 4, and 5 are one-line labels. The column after all the labels are all JScrollPane/JTextPanes.
So first I created a JPanel containing all the labels, using a BoxLayout/Y-Axis. I put that panel in the main JPanel (which uses a BorderLayout), on the WEST side. That scrunches up the vertical box, and allows the vertical box to resize properly.
I wanted to do the same thing with the text pane column -- put them all in a JPanel using a BoxLayout/Y-Axis, and put it in the main JPanel in the CENTER, which I thought would just expand the box to take up the rest of the space.
However, it seems that no matter what I do, all of the JScrollPane/JTextPanes end up taking up an equal amount of space. I even tried setting the top scroll pane's maximum height to be equal to the top label's maximum height, but for whatever reason one or the other layout just ignored that.
Any ideas here?
Thanks!

NOTE: In this code, jPanel1 is the label panel, and jPanel2 is the scrollpane panel.jScrollPane2 is the top scrollpane, and is supposed to take up only enough vertical space to equal the first label, while jScrollPane1 should take up the rest of the space. What happens in practice is that both scrollpanes take up an equal amount of vertical space.
