Hi Michael,
a handling of the selection could maybe look like this.
ISelection selection selection =
PlatformUI.getWorkbench().getActiveWorkbenchWindow().getSele ctionService().g
etSelection();
IStructeredSelection strucSelection = null;
if (selection instanceof IStructeredSelection) {
strucSelection = (IStructeredSelection)) selection;
if (strucSelection.size()==0){
//handle wrong selection
} else if (strucSelection.size()==1){
Object selectedObj = structSelection.getFirstElement();
if (selectedObj instanceof IFile) {
IFile selectedFile = (IFile) selectionObj;
//do something with the file
} else if (selectedObj instanceof CompilationUnit){
CompilationUnit selectedUnit = (CompilationUnit) selectedObj;
//do something with the compilation unit
}
} else{
Iterator iter = structSelection.iterator();
//do something with the multiple selection
}
} else {
//handle wrong selection
}
Note that a selection could be multiple and that if you are in the Java
perspective you got a CompilationUnit instead of a IFile if a Java file was
selected. In most cases it's not necessary to get the Workbench from the
PlatformUI, because inherited methods will give you the Workbench as a
parameter, but using PlatformUI it should always work.
Take Care
