public BetweenOperatorLayout()

Method Detail

initDisplay

public void initDisplay(Display displayToLay)

According to the operator, the layout manager has to add some components (e.g. brackets, ...) or has to perform some "re-oganisation" before rendering.
As soon as the layout manager is set to the display, this mehtod MUST be called with the display laid out as parameter. This method serves as well as a registering method. So all sub-classes of the instance MUST call super.initDisplay(displayToLay).

Overrides:

initDisplay in class DisplayLayout

Parameters:

displayToLay - the display laid by the instance

validateSelection

public void validateSelection()

Checks the validity of the selection.

Specified by:

validateSelection in class DisplayLayout

validateDeselection

public void validateDeselection(Display display)

Checks the validity of the deselection.

Specified by:

validateDeselection in class DisplayLayout

Parameters:

display - the display to deselect.

computeAttributes

public java.awt.Dimension computeAttributes()

Computes the size of the display according to its children size (if any), and its different attributes.

Overrides:

computeAttributes in class VerticalCenteredLayout

Returns:

the size of the display.

rebuildDisplay

public void rebuildDisplay()

The display needs to be rebuilt. We do this.

Specified by:

rebuildDisplay in class DisplayLayout
