Sets the alignment for this layout. Allowable values are FlowLayout.LEFT, FlowLayout.CENTER and FlowLayout.RIGHT.

getAlignment

public int getAlignment()

Gets the alignment for this layout.

minimumSize

public Dimension minimumSize(Container container_)

Calculate the minimum-size rectangle that can enclose all the components in the given container.

Specified by:

minimumSize in interface LayoutManager

doLayout

public void doLayout(Container container_)

Lay out the components according to the specified alignment, hgap and vgap. This is called when the size of the container has already been calculated. It lays out the components in a row, one at a time, until it determines that there is not enough space left in the row. Then it moves to the next row. If there is not enough vertical space in the container to lay out all of the components, it removes the remaining components from the container; they don't appear at all.
