Method Detail

init

public void init()

Description copied from class: PjWorkshop

Initialize and reset project, stops the running animation if any. Does not reset any registered display nor geometry. They must be reset individually in each subclass.

Overrides:

init in class PjWorkshop

reset

public void reset()

Reset workshop and geometry to original state.

Overrides:

reset in class PjWorkshop

update

public boolean update(java.lang.Object event)

Each time another geometry is loaded.

Specified by:

update in interface PsUpdateIf

Overrides:

update in class PjWorkshop

Parameters:

event - sender of this update.

Returns:

true if update was correctly handled by superclass.

See Also:

PsObject.setParent(PsUpdateIf), PsObject.getFather(), PsObject.addUpdateListener(PsUpdateIf)

cancel

public void cancel()

Description copied from class: PjWorkshop

Cancel operation of this workshop by resetting the assigned geometry, and finally close this workshop.

If necessary, the duplicate of the original geometry is restored into the geometry. The update method of the geometry is called.

Overrides:

cancel in class PjWorkshop

ok

public void ok()

Description copied from class: PjWorkshop

Accept current version of the geometry as new version. Close workshop. The copy of the original geometry is ignored.

Implementation in this class calls close().

Overrides:

ok in class PjWorkshop

showOnlyGrayLevels

public void showOnlyGrayLevels(boolean gl)

The workshop and can assign colors to the surface according to the value of the scalar field. Here one can switch between full colors and only grey-levels. If set to true grey-levels are shown, it shows full colors if set to false.

isShowingOnlyGrayLevels

public boolean isShowingOnlyGrayLevels(boolean gl)

The workshop and can assign colors to the surface according to the value of the scalar field. One can switch between full colors and only grey-levels. True - greylevels, false - full colors.
