Method Detail

addLayoutComponent

public void addLayoutComponent(String name,
                               Component comp)

Adds the given component in this layout on the specified by name position.

Overrides:

addLayoutComponent in class FitLayout

Parameters:

name - the constraint giving the position of the component in this layout

comp - the component to add

areAspectRatiosEqual

public static boolean areAspectRatiosEqual(Dimension size,
                                           int width,
                                           int height)

Determines whether the aspect ratio of a specific Dimension is to be considered equal to the aspect ratio of specific width and height.

Parameters:

size - the Dimension whose aspect ratio is to be compared to the aspect ratio of width and height

width - the width which defines in combination with height the aspect ratio to be compared to the aspect ratio of size

height - the height which defines in combination with width the aspect ratio to be compared to the aspect ratio of size

Returns:

true if the aspect ratio of size is to be considered equal to the aspect ratio of width and height; otherwise, false
