Method Detail

run

public void run(org.eclipse.jface.action.IAction action)
Double the cells containing integers in the selected rows.

Specified by:
run in interface org.eclipse.ui.IActionDelegate
See Also:
IActionDelegate.run(IAction)

selectionChanged

public void selectionChanged(org.eclipse.jface.action.IAction action,
                             org.eclipse.jface.viewers.ISelection selection)
Enable the action if there is at least one cell containing an integer. This evaluation is done checking each cell, but note that MiniSSRowActionFilter allows action delegates to do the same thing without having to load their code first. Below is an excerpt from com.ibm.jdg2e.msseditor.extras. that demonstrates this point.
