Constructor Detail

MatchSizeAction

public MatchSizeAction(IWorkbenchPart part)
Constructs a MatchSizeAction and associates it with the given part.

Parameters:
part - The workbench part associated with this MatchSizeAction
Method Detail

calculateEnabled

protected boolean calculateEnabled()
Description copied from class: WorkbenchPartAction
Calculates and returns the enabled state of this action.

Specified by:
calculateEnabled in class WorkbenchPartAction
Returns:
true if the action is enabled
See Also:
WorkbenchPartAction.calculateEnabled()

getPreciseHeightDelta

protected double getPreciseHeightDelta(PrecisionRectangle precisePartBounds,
                                       PrecisionRectangle precisePrimaryBounds)
Returns the height delta between the two bounds. Separated into a method so that it can be overwritten to return 0 in the case of a width-only action.

Parameters:
precisePartBounds - the precise bounds of the EditPart's Figure to be matched
precisePrimaryBounds - the precise bounds of the Primary Selection EditPart's Figure
Returns:
the delta between the two heights to be used in the Request.

getPreciseWidthDelta

protected double getPreciseWidthDelta(PrecisionRectangle precisePartBounds,
                                      PrecisionRectangle precisePrimaryBounds)
Returns the width delta between the two bounds. Separated into a method so that it can be overriden to return 0 in the case of a height-only action.

Parameters:
precisePartBounds - the precise bounds of the EditPart's Figure to be matched
precisePrimaryBounds - the precise bounds of the Primary Selection EditPart's Figure
Returns:
the delta between the two widths to be used in the Request.

run

public void run()
Executes this action, cycling through the selected EditParts in the Action's viewer, and matching the size of the selected EditPart's Figures to that of the Primary Selection's Figure.

Specified by:
run in interface IAction
Overrides:
run in class Action
