in eclipse plugin, how to customize path editor element browse button to open at a given absolute path

Question

Hi

I am making a plugin whose Gui is having path editor element.
I want to make the browse button such that on clicking it open the directory from a given absolute path.
I researched in depth: it seems the path editor.getNewInputObject() is responsible for the setting the filter which set the position in the directory dialog.

Please suggest a solution
