Method Detail

check

public java.awt.Rectangle check(ScreenDockWindow window)

Description copied from interface: BoundaryRestriction

Calculates the bounds which window can have.

Specified by:

check in interface BoundaryRestriction

Parameters:

window - the window whose bounds should be checked.

Returns:

the new boundaries of window, can be null to indicate that the current boundaries are valid.

check

public java.awt.Rectangle check(ScreenDockWindow window,
                                java.awt.Rectangle target)

Description copied from interface: BoundaryRestriction

Calculates the bounds which window can have.

Specified by:

check in interface BoundaryRestriction

Parameters:

window - the window whose future bounds should be checked.

target - the bounds window should have, this method should not write into target.

Returns:

the new boundaries, null to indicate that target is valid.

measureBounds

protected double measureBounds(ScreenDockWindow window,
                               int x,
                               int y,
                               int width,
                               int height,
                               java.awt.GraphicsDevice device)

Checks how good window fits into the screen device

Parameters:

window - the window that is checked

x - the desired x-coordinate

y - the desired y-coordinate

width - the desired width

height - the desired height

device - the targeted screen

Returns:

a value between 0 and 1, where 0 means "does not fit" and 1 means "perfect".

boundsInDevice

protected java.awt.Rectangle boundsInDevice(ScreenDockWindow window,
                                            int x,
                                            int y,
                                            int width,
                                            int height,
                                            java.awt.GraphicsDevice device)

Calculates size and location of dialog such that it is in device.

Parameters:

window - the window to check

x - the desired x-coordinate

y - the desired y-coordinate

width - the desired width

height - the desired height

device - the screen in which to show this dialog

Returns:
