java - Eclipse PDE - How to sort the Properties in the Standard Propeties view -

i'm developing eclipse 3.6 plugin, , have view contains treeviewer. when item treeviewer selected, properties appear in standard properties view. properties ordered alphabetically default.
order these properties differently.

it seems else has had problem too:
http://www.eclipse.org/forums/index.php/m/393029/

the properties in properties view of default generated editor sorted alphabetical order. ask how modify , arrange them in different orders.

the suggested solution is:

your editor needs provide propertysheetpage getadapter(class) method. if doesn't provide 1 property sheet use default propertysheetpage, uses standard collator produce sort order. getadapter() method needs provide specialized subclass of propertysheetpage sets sorter instead.

so need subclass propertysheetpage, override setsorter method , should fine.

two questions arise:

1. why write in documentation that:

   this class may instantiated; not intended subclassed.

2. where make link between standard properties view , subclass of propertysheetpage?
   not using editor in case, have treeviewer when item selected provides properties.
   
   any support appreciated!

i ran same thing , found solution.

what did add sort sequence prefix id of property pages contributing (basically 3 digit number) , create contributioncomparator took first 3 digits of id , basic sort.

the code looks this:

@override public int compare(icomparablecontribution c1,         icomparablecontribution c2) {      int result = super.compare(c1, c2);      iplugincontribution pc1 = (iplugincontribution)c1;     iplugincontribution pc2 = (iplugincontribution)c2;      string id1 = pc1.getlocalid().substring(0,3);     string id2 = pc2.getlocalid().substring(0,3);      result = id1.compareto(id2);      return result; } 

then, in workbenchadvisor, overrode getcomparitorfor method instantiate contributioncomparator created if contributiontype property:

@override public contributioncomparator getcomparatorfor(string contributiontype) {     contributioncomparator cc;      if (contributiontype.equals(icontributionservice.type_property)) {         cc = new mycontributioncomparator();     } else {         cc = super.getcomparatorfor(contributiontype);     }      return cc; } 

now property pages show in order want them to.
