getting a link's URL or the content of a tooltip

Posted: 09 Jul 2014, 11:51

In FireFox, whenever I place the cursor on a hyper-link, in the lower left corner of the screen I see the URL of that link ("link's location"), and right next to the cursor a tool-tip appears containing one word that I want to "catch" (for example, to place it into the clipboard or some other variable). The URL that is shown in the lower left corner of the screen also contains that word, which I can "fish out" of the URL by means of RegExMatch. So I only need to catch either that URL or the content of the tooltip. How can I do that in AHK?

You will need Acc.ahk.

Code: Select all

; From http://www.autohotkey.com/board/topic/77303-acc-library-ahk-l-updated-09272012/?p=493839

f1:: MsgBox % GetTextUnderMouse()

GetTextUnderMouse() {
	Acc := Acc_ObjectFromPoint(child)
	try value := Acc.accValue(child)
	if Not value
		try value := Acc.accName(child)
	return value
}
And check out Accessible Info Viewer.

WOW! Thank you very much tmplinshi! It works.

And thank you also for the links.

Code: Select all

f1:: MsgBox % GetTextUnderMouse()

GetTextUnderMouse() {
	Acc := Acc_ObjectFromPoint(child)
	try value := Acc.accValue(child)
	if Not value
		try value := Acc.accName(child)
	return value
}
This code does not work with google chrome address bar.
But this code works:

Code: Select all

f1::
hwndChrome := WinExist("ahk_class Chrome_WidgetWin_1")
AccChrome := Acc_ObjectFromWindow(hwndChrome)
AccAddressBar := GetElementByName(AccChrome, "Address and search bar")
MsgBox % AccAddressBar.accValue(0)
return

GetElementByName(AccObj, name) {
   if (AccObj.accName(0) = name)
      return AccObj

   for k, v in Acc_Children(AccObj)
      if IsObject(obj := GetElementByName(v, name))
         return obj
}
Anybody knows why?

This worked for me by using accParent. Perhaps the element under the cursor was too far down the hierarchy. Cheers.

Code: Select all

q:: ;google chrome - get address bar text (when hovered over it)
Acc := Acc_ObjectFromPoint()
Acc := Acc.accParent
Acc := GetElementByName(Acc, "Address and search bar")
if IsObject(Acc)
	MsgBox, % Acc.accValue(0)
return

Thank You.
Do You think is it possible to get text without using GetElementByName(Acc, "Address and search bar")?
I mean - how to mofify GetTextUnderMouse() function to show text in such situations?

Here's an attempt at a function to get the text from under the cursor. Cheers.

Code: Select all

q:: ;acc get text under cursor
;first available name and value (may be from different elements):
MsgBox, % JEE_AccGetTextUnderCursor("n") "`r`n`r`n" JEE_AccGetTextUnderCursor("v")
JEE_AccGetTextUnderCursor("v", oAcc1, vChildID1)
JEE_AccGetTextUnderCursor("n", oAcc2, vChildID2)
;name/value from element with first available value:
MsgBox, % oAcc1.accName(vChildID1) "`r`n`r`n" oAcc1.accValue(vChildID1)
;name/value from element with first available name:
MsgBox, % oAcc2.accName(vChildID2) "`r`n`r`n" oAcc2.accValue(vChildID2)
return

Thank You.
It does not work with chrome bookmarks bar.

This quick fix works, although it breaks the script for lower level text.

Code: Select all

;before:
oAcc := oAcc.accParent
;after:
Loop, 2
	oAcc := oAcc.accParent
The problem is that there isn't an easy way to decide how many levels up to check text, as mentioned here:
How to get the full ACC path for control on cursor? - AutoHotkey Community
https://autohotkey.com/boards/viewtopic.php?f=5&t=56470

[EDIT:] Here's an improved function that can check further up the hierarchy until a match is found.

Code: Select all

q:: ;acc get text under cursor
;first available name and value (may be from different elements):
MsgBox, % JEE_AccGetTextUnderCursor("n") "`r`n`r`n" JEE_AccGetTextUnderCursor("v")
JEE_AccGetTextUnderCursor("v", oAcc1, vChildID1)
JEE_AccGetTextUnderCursor("n", oAcc2, vChildID2)
;name/value from element with first available value:
MsgBox, % oAcc1.accName(vChildID1) "`r`n`r`n" oAcc1.accValue(vChildID1)
;name/value from element with first available name:
MsgBox, % oAcc2.accName(vChildID2) "`r`n`r`n" oAcc2.accValue(vChildID2)
return

Here's a script to get the url under the cursor from Chrome. Tested with Chrome v70. Is there a better way?

Code: Select all

q:: ;chrome - get url under cursor
SendInput, {Click right}
Clipboard := ""
Sleep, 30
SendInput, e ;Copy link address
ClipWait, 3
MsgBox, % Clipboard
return

It is interesting for me is it possible with acc always get info under cursor.
Your last improved function works good, but it is no so fast, therefore I think it is better to modify it like this:
And it does not work with chrome "Bookmark this page icon" - it shows wrong element, also it does not work with blank url in address bar - it shows "search icon".

Code: Select all

f1:: MsgBox % GetTextUnderMouse()

GetTextUnderMouse() {
	Acc := Acc_ObjectFromPoint(child)
	try value := Acc.accValue(child)
	if Not value
		try value := Acc.accName(child)
	if (value = "")
                    value := JEE_AccGetTextUnderCursor("v")
	if (value = "")
                    value := JEE_AccGetTextUnderCursor("n")
        return value
}

While testing I notice that this situation is only with object pane, therefore I modify function like this:

Code: Select all

f1:: MsgBox % GetTextUnderMouse()

GetTextUnderMouse()
{
   Acc := Acc_ObjectFromPoint(child)
   try value := Acc.accValue(child)
   if Not value
      try value := Acc.accName(child)
   if (Acc.accRole(child) = 16)   ; pane
   {
      CoordMode, Mouse
      MouseGetPos, OutputVarX, OutputVarY, OutputVarWin
      loop
      {
         Acc := Acc.accParent
         if (Acc_WindowFromObject(Acc) != OutputVarWin)
            break
         try oChildren := Acc_Children(Acc)
         for _, oChild in oChildren
         {
            oCoords := Acc_Location(oChild)
            if (OutputVarX >= oCoords.x) and (OutputVarX <= oCoords.x + oCoords.w) and (OutputVarY >= oCoords.y) and (OutputVarY <= oCoords.y + oCoords.h)
            {
               try value := oChild.accValue(0)
               if Not value
                  try value := oChild.accName(0)
               try role := oChild.accRole(0)
               if (role != 16)  ; pane
                  break 2
            }
         }
      }
   }
   return value
}
