The view class which encapsulates all drawing functionality
Copyright: (C) (C) 1996 Free Software Foundation, Inc.
NSView is an abstract class which provides facilities for drawing in a window and receiving events. It is the superclass of many of the visual elements of the GUI.
In order to display itself, a view must be placed in a window (represented by an NSWindow object). Within the window is a hierarchy of NSViews, headed by the window's content view. Every other view in a window is a descendant of this view.
Subclasses can override -drawRect:
in order to implement their appearance. Other methods of NSView and NSResponder can also be overridden to handle user generated events.

- AppKit/NSView.h

defaultMenu;
Availability: MacOS-X 10.0.0
Returns the default menu to be used for instances of the current class; if no menu has been set through setMenu: this default menu will be used.
NSView's implementation returns nil
. You should override this method if you want all instances of your custom view to use the same menu.

if none is focused.

- (void)
allocateGState;
Availability: OpenStep
Tell the view to maintain a private gstate object which encapsulates all the information about drawing, such as coordinate transforms, line widths, etc. If you do not invoke this method, a gstate object is constructed each time the view is lockFocused. Allocating a private gstate may improve the performance of views that are focused a lot and have a lot of customized drawing parameters.
View subclasses should override the setUpGstate method to set these custom parameters.

NSView*)
ancestorSharedWithView: (
NSView*)aView;
Availability: OpenStep
Returns self if aView is the receiver or aView is a subview of the receiver, the ancestor view shared by aView and the receiver if any, or aView if it is an ancestor of the receiver, otherwise returns nil
.

autoscroll: (
NSEvent*)theEvent;
Availability: OpenStep
Finds the nearest enclosing NSClipView and, if the location of the event is outside it, scrolls the NSClipView in the direction of the event. The amount scrolled is proportional to how far outside the NSClipView the event's location is. This method is suitable for calling periodically from a modal event tracking loop when the mouse is dragged outside the tracking view. The suggested period of the calls is 0.1 seconds.
- (void)
beginDocument;
Availability: MacOS-X 10.0.0
Writes header and job information for the PostScript document. This includes at a minimum, PostScript header information. It may also include job setup information if the output is intended for a printer (i.e. not an EPS file). Most of the information for writing the header comes from the NSPrintOperation and NSPrintInfo objects associated with the current print operation. There isn't normally anything that the program needs to override at the beginning of a document, although if there is additional setup that needs to be done, you can override the NSView's methods endHeaderComments, endPrologue, beginSetup, and/or endSetup. This method calls the above methods in the listed order before or after writing the required information. For an EPS operation, the beginSetup and endSetup methods aren't used.

Availability: OpenStep
Description forthcoming.
- (void)
drawRect: (NSRect)rect;
Availability: OpenStep
This method is invoked to handle drawing inside the view. The default NSView's implementation does nothing; subclasses might override it to draw something inside the view. Since NSView's implementation is guaranteed to be empty, you should not call super's implementation when you override it in subclasses. drawRect: is invoked when the focus has already been locked on the view; you can use arbitrary postscript functions in drawRect: to draw inside your view; the coordinate system in which you draw is the view's own coordinate system (this means for example that you should refer to the rectangle covered by the view using its bounds, and not its frame). The argument of drawRect: is the rectangle which needs to be redrawn. In a lossy implementation, you can ignore the argument and redraw the whole view; if you are aiming at performance, you may want to redraw only what is inside the rectangle which needs to be redrawn; this usually improves drawing performance considerably.

NSMenu*)
menuForEvent: (
NSEvent*)theEvent;
Availability: MacOS-X 10.0.0
Returns the menu that it appropriates for the given event. NSView's implementation returns the default menu of the view.
This methods is intended to be overriden so that it can return a context-sensitive for appropriate mouse's events. ((although it seems it can be used for any kind of event)
This method is used by NSView's rightMouseDown: method, and the returned NSMenu is displayed as a context menu
Use of this method is discouraged in GNUstep as it breaks many user interface guidelines. At the very least, menu items that appear in a context sensitive menu should also always appear in a normal menu. Otherwise, users are faced with an inconsistant interface where the menu items they want are only available in certain (possibly unknown) cases, making it difficult for the user to understand how the application operates

Availability: OpenStep
Removes the receiver from its superviews list of subviews, by invoking the superviews -removeSubview:
method, and marks the rectangle that the reciever occupied in the superview as needing redisplay.
This is dangerous to use during display, since it alters the rectangles needing display. In this case, you can use the -removeFromSuperviewWithoutNeedingDisplay
method instead.

Availability: OpenStep
As an exception to the general rules for threads and gui, this method is thread-safe and may be called from any thread. Display will always be done in the main thread. (Note that other methods are in general not thread-safe; if you want to access other properties of views from multiple threads, you need to provide the synchronization.)
- (void)
setNeedsDisplayInRect: (NSRect)invalidRect;
Availability: OpenStep
Inform the view system that the specified rectangle is invalid and requires updating. This automatically informs any superviews of any updating they need to do. As an exception to the general rules for threads and gui, this method is thread-safe and may be called from any thread. Display will always be done in the main thread. (Note that other methods are in general not thread-safe; if you want to access other properties of views from multiple threads, you need to provide the synchronization.)
- (void)
setNextKeyView: (
NSView*)aView;
Availability: OpenStep
The effect of the -setNextKeyView:
method is to set aView to be the value returned by subsequent calls to the receivers -nextKeyView
method. This also has the effect of setting the previous key view of aView, so that subsequent calls to its -previousKeyView
method will return the receiver.
As a special case, if you pass nil
as aView then the -previousKeyView
of the receivers current -nextKeyView
is set to nil
as well as the receivers -nextKeyView
being set to nil
.
This behavior provides MacOS-X compatibility.
If you pass a non-view object other than nil
, an NSInternaInconsistencyException is raised.
NB This method does NOT cause aView to be retained, and if aView is deallocated, the [NSView -dealloc]
method will automatically remove it from the key view chain it is in.
For keyboard navigation, views are linked together in a chain, so that the current first responder view can be changed by stepping backward and forward in that chain. This is the method for building and modifying that chain.
The MacOS-X documentation refers to this chain as a loop, but the actual implementation is not a loop at all (except as a special case when you make the chain into a loop). In fact, while each view may have only zero or one next view, and zero or one previous view, several views may have their next view set to a single view and/or their previous views set to a single view. So the actual setup is a directed graph rather than a loop.
While a directed graph is a very powerful and flexible way of managing the way views get keyboard focus in response to tabs etc, it can be confusing if misused. It is probably best therefore, to set your views up as a single loop within each window.
