Parameters:

component - the component connected to the area.

x1 - the X-coordinate of the upper left corner of the area c is supposed to occupy.

y1 - the Y-coordinate of the upper left corner of the area c is supposed to occupy.

x2 - the X-coordinate of the lower right corner of the area c is supposed to occupy.

y2 - the Y-coordinate of the lower right corner of the area c is supposed to occupy.

Throws:

GridLayout.OverlapsException - if the new component overlaps with any of the components already in the grid

Method Detail

overlaps

public boolean overlaps(GridLayout.Area other)

Tests if the given Area overlaps with an another Area.
