Method Detail

setLocation

public static void setLocation(org.eclipse.swt.widgets.Shell window,
                               int position)

getLocation

public static org.eclipse.swt.graphics.Point getLocation(org.eclipse.swt.graphics.Point windowSize,
                                                         int position)

Get location needed to place window at a specified alignmnent on the screen.

Parameters:

windowSize - The size of the window to place.

position - The position of the window. A bitmask of one of the HORIZ_* constants with one of the VERT_* constants, eg "HORIZ_TOP | VERT_CENTER".

Returns:

The new location.

getLocation

public static org.eclipse.swt.graphics.Point getLocation(org.eclipse.swt.graphics.Rectangle parentRect,
                                                         org.eclipse.swt.graphics.Point childSize,
                                                         int position)

Align a child window relative to its parent.

Parameters:

parentRect - The parent window.

childSize - The size of the child window.

position - The child's alignment relative to parent.

Returns:

The new location.

Get location needed to place a child window relative to a parent (or the screen) using an imaginary strut connecting 8 points on the parent and child window's borders.

Parameters:

parentRect - The parent window. May be null in which case the screen dimensions are used.

fromPoint - The point on the parent to connect the strut. A bitmask of one of the HORIZ_* constants with one of the VERT_* constants, eg "HORIZ_TOP | VERT_CENTER".

childSize - The child window size.

toPoint - The point on the child to connect the strut. Same format as fromPoint.

direction - The direction of the strut.

distance - The length of the strut.

Returns:

The new location.
