Example 3 with IHopFileType

use of org.apache.hop.ui.hopgui.file.IHopFileType in project hop by apache.

 * We need to figure out which file is open at the given time so we can save it.
 * To do this we see which is the active perspective.
 * Then we ask the perspective for the shown/active file.
 * We then know the filter extension and name so we can show a dialog.
 * We can then also have the {@link IHopFileType to save the file.
 *
 * @return The original filename, not having any variables replaced.  It returns null if no file was saved
