In the image linked here there are 3 runs of the same little scribble application overlapping. The pixels only get drawn when the mouse is in the top overlapping window. I'm just a little confused on the reason to track the lack of mouse input in the window when ... none gets reported if the mouse isn't in the window. Am I missing something?
Hi James D Jarvis
thanks for your feedback!

Quote:Isn't the lack of mouseinput the easiest way to tell the mouse isn't in the window?I think it is not so simple. Here in the bottom I post an image of 3 different apps (run) of the same program that I have posted here as a program that detects if mouse pointer is out or in the area of the window.
As you can see, all three applications in running show a correct result about the position of the pointer of the mouse. So it seems that mouse information are shared among them.

Moreover if you run this code you can see that also when mouse is out of window of the program after a call to _MouseInput you get back mouse informations like _MouseX and _MouseY, _MouseMovementX and _MouseMovementY.
run this code to verify
Code: (Select All)
Rem it is a code test to detect mouse out of window of application
Option _Explicit
Dim As Long S1, W1, H1
Dim As Integer Xm, Ym, Dxm, Dym, Im, Ox, Oy
W1 = 800: H1 = 600
S1 = _NewImage(W1, H1, 32)
Screen S1
Print " Dxm Dym Xm Ym"
View Print 2 To 30
Do
Im = _MouseInput ' here we call a mouseinput queque
If Im Then ' if mouseinput is true
Dxm = _MouseMovementX ' we store mousemovementX
Dym = _MouseMovementY ' we store mousemovementY
Xm = _MouseX
Ym = _MouseY
Print Dxm, Dym, Xm, Ym
End If
_Limit 300
Loop Until InKey$ <> ""
End
Here a screenshot

I dunno if it is right to get back info about mouse when it leaves the area of window's application.
I think that it is the actual behaviour of the OS (MS Window). But Someoneelse can test the code in Linux or Mac platforms.
Waiting more feedbacks
