mouse - In Cocoa, what is the best way to change the cursor when hovering over a circular view? -

What do I do

I have a circular custom NSView subclass , And I want to change the appearance of the cursor when the mouse is hovering over the circular part of the view, but not when there are parts of the rectangle of that scene which falls outside the circle.

I would have outlined it with an image tag, but I am also new to being part of such awesome features.

What do I know till now?

I know how to change the appearance of the cursor through the nicers, I think it's rectangular The best way to complete the cursor will be with the rectangle I know that I can get a mouse mood event (and when the mouse is not using the mouse attribute and mousex on this view, then they should be closed), and To determine A simple, inexpensive method is whether or not a point is in the field of interest.

Then what's the problem?

As far as I can tell, the system does not send the mouse using the event in a view that is not the first responder. Therefore, if I want to receive mousemovaged events to see the mouse, when mouse is hovering over my scene, then I need to steal the position of the suspenders, which is currently if there is a text view focus , Then simply stole it from moving the mouse over the scene, which is unacceptable from the point of view of usability.

So, my question is: Is there a better way to do this? Can I get mouse movers events without first responding?

Thank you!

I will add the following tag: Custom-view mouse-event assistant first responder but again, I can not do a SA Noob so I can.

I think you may need to accept NSView to return to yes if you If you do not do this, the scene will not get information about an event.

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
