<p>Effectively, if your 3rd party app defines a custom pixmap cursor
whose ID is not a constant, you cannot retrieve it.</p>
<p>Or perhaps if you test this cursor comparing it with all constant
values enumerated in cursorfont.h, if it does not correspond with
any of these, it could be your 3rd party app window.</p>
<p>Sorry, but I can't help you more.</p>

<p>Don't you know the ID of your custom pixmap cursors ?</p>
<p>If you do, you can add them to the cases of the switch.<br>

<p>Hello,</p>
<p>Perhaps you should look at XTest
extension : <a

<p>See <code>XTestCompareCursor function<br>

<div dir="ltr">So XSetWindowAttributes
allows you to set the cursor on the
window, basically this is the hardware
cursor when your mouse enters the
window that is displayed. <br>
<br>
Is there a way to readback this value
from an existing window? Or perhaps
another workaround to get the cursor
on a specific window?<br>
<br>
I am aware there is
XFixesSelectCursorInput but this
listens for changes and grabs the
current system cursor; not on a per
window basis.<br>
