:: Reference :: Columns & Rows ::

Columns and rows are specified by three parts:

a mandatory initial size
an optional default alignment
an optional resizing behavior

For example, you can specify that a column is left aligned, has an initial size of 50 Dialog Units and grows: new ColumnSpec("left:50dlu:grow");

Resizing Behavior

Columns and rows can grow if the layout container becomes larger than the preferred size. By default, columns and rows won’t resize. The extra space is distributed over the columns and rows that have a resize weight larger than 0.0, where each column gets a space proportional to its weight.

String Representations

String representations for column and row specifications can be used in the FormLayout constructors as well as in classes ColumnSpec, RowSpec.

columnSpec     ::= [columnAlignment:] size [:resizeBehavior]
rowSpec        ::= [rowAlignment   :] size [:resizeBehavior]
resizeBehavior ::= NONE | GROW | GROW() | G()

Examples

new ColumnSpec("16px");
new ColumnSpec("left:16px");
new ColumnSpec("left:16px:grow");

new FormLayout("right:max(50dlu;pref), 4dlu, max(100dlu;min)", 
               "p, 3dlu, p, 3dlu, fill:200dlu:grow");
