Right Click an Element

This example uses the getBoundingClientRect method and a Windows API method to 1) get the mouse coordinates of a particular object and 2) to click that element. This code is taken from Paul Rogers and Bill Agee (see links below) with a little help from me putting it in one place. There are two examples below. The first example goes to the TSA site and right clicks on a link that brings up a PDF. Although the send_keys method uses AutoIt, the rest of the example uses only Windows functions. The second example goes to the EXTJS site and uses the left_click method to click the tab. This has previously resisted many attempts at clicking since EXTJS needs an actual mouse click (not a simulated one). Possibly Watir will be extended soon to include these methods and other code being worked on by others. If this happens I will update this page.

I have not tested this code for Firefox and I have no reason to believe it will work (sorry).

require 'watir'

module Watir
  class Element
    def top_edge
      assert_exists
      assert_enabled
      ole_object.getBoundingClientRect.top.to_i
    end

    def top_edge_absolute
      top_edge + page_container.document.parentWindow.screenTop.to_i
    end

    def left_edge
      assert_exists
      assert_enabled
      ole_object.getBoundingClientRect.left.to_i
    end

    def left_edge_absolute
      left_edge + page_container.document.parentWindow.screenLeft.to_i
    end

    def right_click
      x = left_edge_absolute
      y = top_edge_absolute
      #puts "x: #{x}, y: #{y}"
      WindowsInput.move_mouse(x, y)
      WindowsInput.right_click
    end

    def left_click
      x = left_edge_absolute
      y = top_edge_absolute
      #puts "x: #{x}, y: #{y}"
      # need some extra push to get the cursor in the right area
      WindowsInput.move_mouse(x + 2, y + 2)
      WindowsInput.left_click
    end
  end
end

module WindowsInput
  # Windows API functions
  SetCursorPos = Win32API.new('user32','SetCursorPos', 'II', 'I')
  SendInput = Win32API.new('user32','SendInput', 'IPI', 'I')
  # Windows API constants
  INPUT_MOUSE = 0
  MOUSEEVENTF_LEFTDOWN = 0x0002
  MOUSEEVENTF_LEFTUP = 0x0004
  MOUSEEVENTF_RIGHTDOWN = 0x0008
  MOUSEEVENTF_RIGHTUP = 0x0010

  module_function

  def send_input(inputs)
    n = inputs.size
    ptr = inputs.collect {|i| i.to_s}.join # flatten arrays into single string
    SendInput.call(n, ptr, inputs[0].size)
  end

  def create_mouse_input(mouse_flag)
    mi = Array.new(7, 0)
    mi[0] = INPUT_MOUSE
    mi[4] = mouse_flag
    mi.pack('LLLLLLL') # Pack array into a binary sequence usable to SendInput
  end

  def move_mouse(x, y)
    SetCursorPos.call(x, y)
  end

  def right_click
    rightdown = create_mouse_input(MOUSEEVENTF_RIGHTDOWN)
    rightup = create_mouse_input(MOUSEEVENTF_RIGHTUP)
    send_input( [rightdown, rightup] )
  end

  def left_click
    leftdown = create_mouse_input(MOUSEEVENTF_LEFTDOWN)
    leftup = create_mouse_input(MOUSEEVENTF_LEFTUP)
    send_input( [leftdown, leftup] )
  end
end

def main()
  # Open google index page, and send a right click to the logo image
  br = Watir::IE.new()
  br.bring_to_front
  br.goto('http://www.tsa.gov/travelers/airtravel/prohibited/permitted-prohibited-items.shtm')
  br.link(:text, 'Click here').focus
  br.link(:text, 'Click here').right_click
  # Then, bring up the properties menu (works with IE6, at least)
  br.send_keys("{DOWN}{DOWN}{DOWN}{ENTER}")

  br.goto('http://extjs.com/deploy/dev/examples/tabs/tabs.html')

  tabs_div = br.div(:id, 'ext-gen6')
  long_text_tab = tabs_div.li(:id, 'ext-comp-1001__ext-comp-1003')
  long_text_tab.left_click # sucess!!
end

if __FILE__ == $0
  main
end

you have 2 or 3 options here I think:
1) re-install Watir with admin privileges

or

2) install AutoIt independent of Watir (not bad because you get the helpfile for the API and the Window Info tool)

or

3) you may be able to just register AutoIt from the command line. See this post from Charley Baker here
"You need to register AutoIt. In a command window, navigate to the directory
where you've put AutoIt and type:
regsvr32 AutoItX3.dll"

Hi Alan - After we discussed a solution that doesn't use a magic number, I got an example working. It also uses SendInput for the mouse motion bits. Let me know what you think:

Chethan -

I ran this on my computer tonight with no problems. The error you are getting leads me to believe that you might have a cut and paste mistake. I have changed the example so it is executable for anyone (I had to get creative with the example, having traveled recently - it was the first downloadable pdf example I could think of).

Let me know if you are still getting the error message after making sure that you have completely pasted the example correctly.

Alan,

I tried with modified script you have provided, Still unable to resolve the error message.
I tried with IRE even, same error message getting popped-up.
do I need to add any more require other than 'watir' or any other windows plugins..?

Suggest me on this.

Chethan -

Sorry I didn't see this earlier, I don't always see updates to the wiki. I'm not sure how else to help. Maybe you can post to watir-general on the google groups list and let me know what specific problems you are having so I can help. You shouldn't need to require anything else other than what is normally required for watir. Also, can you tell me what line number in the above code is generating the error?

Hello Chethan

I too received similar issue with this code.

After days of troubleshooting, I found out this,

change this,
SetCursorPos = API.new('SetCursorPos', 'II', 'I', 'user32')
SendInput = API.new('SendInput', 'IPI', 'I', 'user32')

to,
SetCursorPos = Win32API.new('user32','SetCursorPos', 'II', 'I')
SendInput = Win32API.new('user32','SendInput', 'IPI', 'I')

works flawless to me

Alan,
thank you for the code. I am a fresher to watir, so i dont understand the logic behind your code. However, I tried my best to troubleshoot using my guess and guts method

Thank you

Sounds like you got it to work. I'm not sure why the previous example didn't though. If you still have questions let me know and I will try and answer.
