Examples with Constraints javax.swing.SpringLayout.Constraints used on opensource projects

Example 6 with Constraints

use of javax.swing.SpringLayout.Constraints in project megameklab by MegaMek.

the class SpringUtilities method makeCompactGrid.

/**
 * Aligns the first <code>rows</code> * <code>cols</code>
 * components of <code>parent</code> in
 * a grid. Each component in a column is as wide as the maximum
 * preferred width of the components in that column;
 * height is similarly determined for each row.
 * The parent is made just big enough to fit them all.
 *
 * @param parent the parent container to organize
 * @param rows number of rows
 * @param cols number of columns
 * @param initialX x location to start the grid at
 * @param initialY y location to start the grid at
 * @param xPad x padding between cells
 * @param yPad y padding between cells
