Constructor Detail

GridLayoutPainter

public GridLayoutPainter(int cellsX,
                         int cellsY)

Creates a new instance

Parameters:

cellsX - The number of cells in x-direction

cellsY - The number of cells in y-direction

Throws:

java.lang.IllegalArgumentException - If any number of cells is negative

GridLayoutPainter

public GridLayoutPainter(int cellsX,
                         int cellsY,
                         double relativeCellBorderSizeX,
                         double relativeCellBorderSizeY)

Creates a new instance with the given border sizes for the cells. The border size is relative, i.e. referring to the total size of the cell. Thus, it will usually be a positive value between 0.0 and 1.0.

Parameters:

cellsX - The number of cells in x-direction

cellsY - The number of cells in y-direction

relativeCellBorderSizeX - The border size of each cell in x-direction

relativeCellBorderSizeY - The border size of each cell in y-direction

Throws:

java.lang.IllegalArgumentException - If any number of cells is negative

Method Detail

getCellsX

public int getCellsX()

Returns the number of cells in x-direction

Returns:

The number of cells in x-direction

getCellsY

public int getCellsY()

Returns the number of cells in y-direction

Returns:

The number of cells in y-direction

setDelegate

public void setDelegate(int x,
                        int y,
                        Painter delegate)

Set the painter for the cell with the given coordinates

Parameters:

x - The x-coordinate of the cell

y - The y-coordinate of the cell

delegate - The delegate

Throws:

java.lang.IndexOutOfBoundsException - If the given indices are invalid
