JTable is an entirely different creature. Although the default cell
renderer is a JLabel, sizing depends on a number of factors. For the down
and dirty, see JTable.doLayout()
http://java.sun.com/j2se/1.4.2/docs/api/javax/swing/JTable.html#doLayout()
JTable row heights: JTable.getRowHeight() - Returns the height of a
table row, in pixels. The default row height is 16.0.
http://java.sun.com/j2se/1.4.2/docs/api/javax/swing/JTable.html#getRowHeight
()
See also getRowHeight(int row), setRowHeight(int rowHeight),
setRowHeight(int row, int rowHeight)
JTable column widths are determined by the individual TableColumn.
Unfortunately, the easiest way to get TableColumns is by
JTable.getColumnModel() - Returns the TableColumnModel that contains all
column information of this table.
http://java.sun.com/j2se/1.4.2/docs/api/javax/swing/JTable.html#getColumnMod
el()
then
TableColumnModel.getColumn(int columnIndex) - Returns the TableColumn
object for the column at columnIndex.
http://java.sun.com/j2se/1.4.2/docs/api/javax/swing/table/TableColumnModel.h
tml#getColumn(int)
Once you have the TableColumn,
TableColumn.getMinWidth() - The default minWidth is 15.
http://java.sun.com/j2se/1.4.2/docs/api/javax/swing/table/TableColumn.html#g
etMinWidth()
TableColumn.getPreferredWidth() - The default preferred width is 75.
http://java.sun.com/j2se/1.4.2/docs/api/javax/swing/table/TableColumn.html#g
etPreferredWidth()
See also getMaxWidth(), setMaxWidth(int maxWidth), setMinWidth(int
minWidth), setPreferredWidth(int preferredWidth)
The books I mentioned earlier go into detail about how all this works
together, including end user resizing on the fly. And you're welcome, hope
you find the AWT book helpful.
There are also several JTable demos included in the JDK, as well as
SwingSet2. Again, the Java Tutorial has a section on JTables. Being good
at GUIs is no different than any other area - no pain, no gain. If the pain
is not acceptable, call in someone who chose to go through it.
