click is over link ? Does it use (x,y)  co-ordinates of clicked area to take
decision ?

Actually, I tried to dig up isOverLink() as follows:

isOverLink()
------------------------------------------------------------------------

|
|
    |calls -

| calls -
m_hitTestResult.URLElement()
m_hitTestResult.URLElement()->isLink()

|
|
    |calls
-
|
m_innerURLElement.get()                                              Then
above isLink() always returns TRUE
    |
Then I could not find out function definition
of above  get() function calls.

I am not getting the logic behind this. If I am wrong then please correct
me..

Thanks in advance,
Vivek


Or is it some other function?
