Re: [gnome-desktop-testing] Selecting an area Gnome-Screenshot

Hi Javier / Michael,

Here is the code: This method takes x, y, width, height (arguments) of the file object co-ordinates in nautilus window in host.

   def LinDragAndDrop(self, serverInst, client, x, y, width, height):

      objList = getobjectlist(mainWindow)
      unkObj = None
      ###################################### Hard coding for testing DnD
      objList = ['unk29']
      for obj in objList:
         if obj.find ('unk') != -1:

            print obj
            self.harness.AddTestComment(obj)
            if hasstate (mainWindow, obj, state.SHOWING) and \
                   hasstate (mainWindow, obj, state.FOCUSED):
               unkObj = obj

               break
      if not unkObj:
         raise ValueError, "Unable to find unknown object"
      vm_x, vm_y, vm_width, vm_height = getobjectsize(mainWindow,
                                                      unkObj)

      print 'File', x, y, width, height
      print 'Guest', vm_x, vm_y, vm_width, vm_height
      # Press mouse button
      generatemouseevent(x + width / 2,
                         y + height / 2,

                         'b1p')
      # Bring Workstation window to focus
      grabfocus(mainWindow, unkObj)
      self.MouseMoveInNautilus(serverInst, client,
                               0, 0, vm_width,

                               vm_height)
      # Move mouse to absolute location
      generatemouseevent(vm_x + vm_width / 2,
                         vm_y + vm_height / 2,
                         'abs')

      wait(1)
      self.MouseActionInNautilus(serverInst, client, 'rel',
                                 0, 0, vm_width, vm_height,
                                 False)
      wait(1)
      self.MouseActionInNautilus(serverInst, client, 'b1p',

                                 0, 0, vm_width, vm_height,
                                 False)
      wait(1)
      self.MouseActionInNautilus(serverInst, client, 'abs',
                                 0, 0, vm_width, vm_height,

                                 False)

      wait(1)
      # Release mouse button
      self.MouseActionInNautilus(serverInst, client, 'b1r',
                                 0, 0, vm_width, vm_height,

                                 False)
#      wait(3)
      print 'Host', vm_x, vm_y, vm_width, vm_height, vm_x + vm_width / 2, vm_y + vm_height / 2
      print 'Guest', 0, 0, vm_width, vm_height, vm_width / 2, vm_height / 2

      generatemouseevent(vm_x + vm_width / 2,
                         vm_y + vm_height / 2,
                         'b1r')
      generatemouseevent(vm_x + vm_width / 2,
                         vm_y + vm_height / 2,

                         'b1c')
      wait(1)

On the guest to operate on nautilus window:

if waittillguiexist (nautilusWindow, guiTimeOut = 2) == 0:
    # If window doesn't exist, then launch

    launchapp ('nautilus')
    waittillguiexist (nautilusWindow)

menucheck(nautilusWindow, 'View;Main Toolbar')
grabfocus(nautilusWindow, 'btnReload')

# To get object x,y co-ordinates, we need to uncheck,

# the following options in nautilus window
menuuncheck(nautilusWindow, 'View;Main Toolbar')
menuuncheck(nautilusWindow, 'View;Side Pane')
menuuncheck(nautilusWindow, 'View;Location Bar')

try:
    x, y, width, height = getobjectsize(nautilusWindow, nautilusWindow)
    generatemouseevent(x + width / 2, y + height / 2, 'abs')
except:
    print traceback.format_exc()

Code which calls the above function:

            x, y, width, height = getobjectsize(nautilusWindow,
                                                testdata ['filename1'])
            guestCommInst.LinDragAndDrop(serverInst, client, x, y,

                                         width, height)

In our scenario, we run a server and client, as the information has to be transferred between host machine and the guest. This may not be required in your automation.

During my DnD automation, I noticed the bug in nautilus. It always gives the coordinates without calculating the toolbar, side pane and location bar. Once you grab the focus of nautilus window, you have to uncheck them. To grab focus of nautilus window, you need to have toolbar visible. The above nautilus code handles this.

MouseActionInNautilus will be done inside the guest.

Thanks
Nagappan

Hello Nagappan,

I was curious about this. Is it possible to generate the drag by sending both
mouse button press and mouse move events?

Best regards,
