I have the same problem with myWindow xid. « bad argument ». Yet I have used all the other methods which also use myWindow xid and display as arguments. I think the problem is from the other arguments passed by reference, not by value. I have seen a new version of Alien from Sept 30, but I don’t know if it works in pharo.

Hi,

I Have tried the following code on Linux , but the call breaks. Is it because of the X11Window structure missing or else ?

Annick ==== testGetOurWindowLocation "self new testGetOurWindowLocation"

| display ourWindow aParent anX anY aWidth aHeight aBorderWidth aDepth | display := X11Display XOpenDisplay: nil. ourWindow := display ourWindow. (Alien lookup: 'XGetGeometry' inLibrary: 'X11') primFFICallResult: nil withArguments: {display. ourWindow. (aParent := Alien new: 4). (anX := Alien new: 4). (anY := Alien new: 4). (aWidth := Alien new: 4). (aHeight := Alien new: 4). (aBorderWidth := Alien new: 4). (aDepth := Alien new: 4)}. (anX unsignedLongAt: 1) inspect

withArguments ... ourWindow xid ... ?
