    Hi All,
    I have a form with a number of line edits, when the user right clicks on a line edit I want to set up an even filter that opens a file dialog to allow the line edit to be filled with a file name. I've worked out how to get event filters running with a left click, however how do I determine if its line edit 1,2,3 ect?
    Thanks

      hi
      you get the lineedit in
      eventFilter( QObject * object ...)

      So object is the line edit.
      you can then cast it to lineedit.
      QLineEdit *TheOne= qobject_cast<QLineEdit *>(object ) ;
      if (TheOne) {
      OpenDialog()
      TheOne->setText(xxx);
      }

          As a side note: Opening a file browse dialog on a right click is not a very common behavior. Usually a small "..." button next to the edit is used for this sort of thing, so a user can discover it easily. It also makes connecting it to the right open function easier.
