I am trying to make a simple application in which there is a empty red rectangle and whenever the mouse is moved over the upper half border of the rectangle the cursor will become closed hand.
I started with selecting the foundation command line project.Made a transparent NSWindow and embedded a NSView in it with the rectangle, made window to accept mouse moved events(by method: -setAcceptsMouseMovedEvents). I have overridden -canBecomeKeyWindow and -canBecomeMainWindow window to return YES. But somehow none of the -mouseMoved events are being received by NSView.
When I put the same code by making a cocoa application project and creating my window in -applicationDidFinishLaunching method , my view was able to receive -mouseMoved events.
why is it not receiving mouse moved events when I use foundation command line utility project ?
I have also observed that whenever I make a window(carbon or cocoa) through foundation cmd line utility project , the window doesn't become key even on clicking the title bar.On clicking the title bar color remains light grey instead of becoming dark grey. Why is this happening?
I have overridden -canBecomeKeyWindow and -canBecomeMainWindow of NSwindow to return YES.
You have no event loop to detect events and pass them to your window because your program does not start an NSApplication. See the main.m file of a typical Cocoa application.
It might be helpful to describe what you're trying to accomplish by taking this approach. My guess is you're building a daemon but want a GUI interface to manage the otherwise "headless" daemon. That or you're building a new login management system. In either case, there are specific ways to do both and this isn't it. :-)
