If the *only* reason for making separate subclasses is the code to extract the data, I don't see any great advantage. You need 22 pieces of code, and it's probably easier for housekeeping purposes to keep them all in one place than to spread them around. (But separate subclasses would be in no way wrong.) If there are other behavioral differences, then it might make more sense to use different subclasses. HTH IMO FWIW There are many other approaches you could take also. In my app I have one document class but a simple schema for extending the types of files it can read and write by mapping file types (and/or UTIs) to specific method selectors. The mapping table is a simple dictionary. This allows me to add the method via a category, amend the mapping table and info.pList and away it goes. The core document class never changes so I can reuse that code in many different apps. This is no better or worse in terms of the amount of code you need to write but it does make managing it quite easy. --Graham ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

A Cocoa Document-Based App is one document one window ... multiple windows. How do I win the battle of 'too many windows floatin' around on the Mac, we want everything in one window like windows! ? MDI is a travesty of UI design. Just one example - drag and drop between windows in different MDI apps is quite frankly, virtually unusable, where it is even attempted at all. The Mac's approach is much better (i.e. more usable), though when there are a lot of windows it can appear confusing to some. However, system features such as Exposé were designed to help overcome the problem of finding a particular window among a lot of clutter and it works well. Spaces is also useful for managing windows among several apps working together in particular ways. The people who are asking you to do this are misguided. If they want to make Mac apps, they should not be thinking about replicating the Windows version on the Mac, but instead fitting in with the way all other Mac apps work. Mac users are notoriously unforgiving of apps that don't work the right way, and apps that are an obvious Windows port do less well in terms of sales and user satisfaction, and in many cases will not be used unless there is absolutely no alternative. The same goes for Java apps to some extent. However I know how hard it can be to get those of a pointy-haired disposition to understand this argument, so you might have an uphill battle. Who matters more - the end user, or the people in the company who think a unified product is easier to handle? (even if in reality it's probably not). Even if they cannot or will not be re-educated, you don't have much choice anyway - the Mac does not support MDI in the Windows sense and faking it would be a huge effort that would be more than entirely wasted - the app will sell less well and be reviewed poorly. --Graham ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

While the full MDI way of doing things would be a bad thing on a Mac for many reasons, simply having multiple documents per single NSWindow is common in Cocoa apps, and there are two main ways that I see people doing this: tabs across the top, like Safari; or a sidebar view down the side, like Mail, iTunes, iChat, etc. Starting with Leopard, the NSSplitView IB widget can be used to set up the views and you can decide how to customize the look (it comes in both vertical and horizontal flavors). You can also used the excellent and flexible 3rd party solutions of RBSplitView and KFSplitView (which are also more backward compatible). If you want it to look like Safari tabs across the top you'll just have to do a little work to make that top bar view behave how you want. Side tabs are much easier to get up and running, and are often a better solution GUI-wise, depending on your app. There are many other ways to skin this cat too, but this is probably the simplest, and it can look quite elegant. jeff ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

I guess I'd ask the question we often ask about coding questions: What are you really trying to do? It sounds like the problem is that Windows users accustomed to MDI get visually confused by multiple windows from different apps overlapping each other willy-nilly. One simple solution to that is Command-Option-H to hide all other apps; there's even a utility out there that will do this for you automatically when you switch apps. There are also utility apps that place a dark gray background between your app's windows and all other apps' windows. Windows has an architecture called Multiple Document Interface.

How do I win the battle of 'too many windows floatin' around on the Mac, we want everything in one window like windows! ? First, there are certain realities that no amount of battling will change: some Windows users want MDI, and the Mac does not support it. Second, it seems to me, to borrow a business cliché, that you're all on the same team, with the same goals -- delivering successful applications. What's not clear to me is why the Windows developers care whether your apps are Windows-like, and why they have any influence over your design. Are they also end-users? Are your apps in-house apps? Do they have authority over your UI decisions or merely complaints? Aren't you there to be the person who knows better about Macs than they do -- or else *they'd* be writing your apps? Can I use Safari tabs somehow? I don't know of any public framework for creating tabbed interfaces. I'm pretty sure there are some good third-party options. If tabs are all it would take to satisfy your co-workers, then sure, you could create an interface they'd like better without violating Mac UI conventions. However, as I recall, MDI is much more than a tabbed interface. It's actually windows within a window, where each sub-window is a real window, complete with in-window menu bar, and the Mac frameworks simply do not support this. The nearest thing would either be a tabbed interface as you suggested or an index-card metaphor like I've seen for at least one app (targeted at writers). The latter would be a much different metaphor than windows within a window, but people who don't get that applications should behave according to the UI rules of their respective platforms probably aren't too sensitive to such nuances. --Andy ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: bypass NSApp
Hi, I took all your remarks into account and I decided to use the event dispatching system that uses the C third party program. So I post an event which will be handled by the main loop of the C third party program. The attached callback intializes the nsapp and in the main thread. To get ride of [NSapp run], I am also posting at regular time, an event and the attached callback calls [NSApp nextEventMatchingMask..], [NSApp sendEvent..]. It also resolves the problem of having several plugins like that (or loading this same plugin several times) The solution is ok but I am still convinced that the NSRunLoop could/should get the ability to perform/handle the events that the NSApp is the only one able to do.

You'd want a button that stays down when the view is displayed (like a popup). You'd want a view in which to display your complicated UI. For this, you'd need a borderless (or custom-drawn) window to position over the control's host window in which to display your custom view. There are examples of both online.

Short answer: No. Long answer: You can get around this, but you won't get instantaneous notifications. iTunes maintains an XML PLIST representation of the database for third-party developers to latch onto for reading only. Using FSEvents for Leopard and above (or UKKQueue for Tiger and before), you can watch this file for changes and respond accordingly. Caveat: This doesn't work on network volumes.

NSTableView - strange behaviour after cell text color assignment
Hi, All,
I'm trying to color my table's rows depending on some value, returning
from a function like this:
int GetState(int rowIndex);
I've searched around the Net and the only clear way I've found is to
set my AppController, as a tableView delegate and respond to the message
- (void)tableView:(NSTableView *)aTableView
willDisplayCell:(id)aCell
forTableColumn:(NSTableColumn *)aTableColumn
row:(int)rowIndex;
I've created this method as the next:
if (rowIndex == selRow)
color = [NSColor selectedTextColor];
else
switch (st = GetState(rowIndex)) {
case 1 : { color = [NSColor colorWithCalibratedRed:0
green:0
blue:0.5
alpha:1.0]; break; }
case 2 : { color = [NSColor colorWithCalibratedRed:0
green:0.5
blue:0
alpha:1.0]; break; }
case 3 : { color = [NSColor colorWithCalibratedRed:0.5
green:0
blue:0
alpha:1.0]; break; }
}
[aCell setTextColor:color];
I've got a strange effect: a new row is selected OK, when I change
selection in the tableview, but the row, which was selected, remains
being drawn with the same selected color unless reloadData will
appear. Therefore, changing selection quickly I can change color of
many rows to selected color, unless update will come. Selection bar
itself looks OK, and selected row background and text color changes
immediately, but how to update the row, which was previously selected?
I believed it will be done by my delegate method. It looks like this
method is called at some not appropriate time. Is there a solution?
Thanks.

UITextView not updating
I asked about this earlier and no one seemed the know the answer.
I have a UITextView inside of a scroll view. The textview is offscreen
when the main view loads. So it does not update when data is loaded in
to it. Thus when ever the scroll it is inside moves I use a standard
scrollview delegate method to detect the scroll. Then execute the code
below.
if(scrollView == miniScroll){
for (UIView *childView in onlinePeopleView.subviews)
{
[childView setNeedsDisplay];
}
}
This does not work. setNeedDisplay does not cause it to update and
display the text inside of the textview. What can I do to cause the
text to be displayed? Everything else is set up correctly in IB and
the text size is unaltered. So I know its none of that. If I NSLog()
the contents of the text view it shows that the textview is infact
imbued with the correct text it simply will not display. How can I
force a textview to update it's display?
Thanks

Re: UITextView not updating
It would be easier to answer this with a sample project.

I asked about this earlier and no one seemed the know the answer.
I have a UITextView inside of a scroll view. The textview is
offscreen when the main view loads. So it does not update when data
is loaded in to it. Thus when ever the scroll it is inside moves I
use a standard scrollview delegate method to detect the scroll. Then
execute the code below.
if(scrollView == miniScroll){
for (UIView *childView in onlinePeopleView.subviews)
{
[childView setNeedsDisplay];
}
}
This does not work. setNeedDisplay does not cause it to update and
display the text inside of the textview. What can I do to cause the
text to be displayed? Everything else is set up correctly in IB and
the text size is unaltered. So I know its none of that. If I NSLog()
the contents of the text view it shows that the textview is infact
imbued with the correct text it simply will not display. How can I
force a textview to update it's display?

Re: iTunes DB Change Notifications?
If Apple is providing the XML file for third party developer use, but they don't provide any way to monitor changes, does that mean that their intention is for third party apps to regularly refresh from the XML file? Isn't this an extremely expensive operation? Particularly when moving data across a network? How about interjecting a Core Data app, running on the machine that maintains the XML file? That machine could monitor the XML file with FSEvents and maintain a CD DB that mirrors the XML file, adding new objects or fetching, updating and then saving changes, as appropriate. On the context's WillSaveNotification, it could alert its clients, sending just the updated information. If this works, the question is, would it be better to maintain mirrored CD DB's on each of the clients (clients will be a mix of Macs and iPhones), and update those databases when changes occur? Or, should they query the server when they need information? The client UI's would be much more responsive if the clients each maintained their own databases, particularly if I wanted to get cover art to the clients, but maintenance gets more complicated.

Arun, my advice is the same. To identify which menu (if any) should get the Search field, AppKit examines the actions of the items in that menu.

Re: NSTableView - strange behaviour after cell text color assignment
Replying to myself: - (void)tableView:(NSTableView *)aTableView willDisplayCell:(id)aCell forTableColumn:(NSTableColumn *)aTableColumn row:(int)rowIndex; The function above works perfectly, but the problem reason was in the incorrect receiving of the selected row index. I wrongly assigned it, as a global variable, within a function, which updated my table data on timer. therefore the selected row index value was changed on timer, but not on real selection change. why didn't 5 set the assignment in the tableViewSelected: action, going from tableView? Really, I did it. But unfortunately this action raises on the mouse clicks only. Keyboard clicks are passing by this action. Fortunately I've found a solution, that really works. I've registered an observer for NSTableViewSelectionDidChangeNotification notification, and now every change of selection is processed. I believe, the question is closed.

Could anybody point me any sample or at least what notifications should I use?

NSXMLDocument and schema validation (Not finding schema document?)

I can parse and process my XML file fine as long as I don't validate, but when I call validateAndReturnError: I'm getting back the error xmlSchemaParse: could not load ''. As far as I can tell, the schema URL in my XML document is fine (I can access it using Safari), and I've validated the same XML document using the same schema URL using XML Nanny. So...I can't figure out why NSXMLDocument can't find my schema. Heck, I've even grabbed the schema URL from the NSXMLDocument root element (by getting the attribute xsi:schemaLocation) and checked that I can access the URL directly using NSString stringWithContentsOfURL:.

Re: How to set the string and integer value of an NSButtonCell using NSOutilneView
Well, according to the documentation, an NSButtonCell's object value
(and all interpretations thereof) correspond to the state of the
button (on, off, or mixed). You want to set this as well as set the
title of the button. Unlike NSBrowser, NSOutlineView's data source
methods don't provide direct access to the cell, it only asks you for
the object value.
It's a bit of a pain, but if you want the button state AND the title
of the button to be affected by object value, you could subclass
NSButtonCell and override -setObjectValue:. THEN, in the datasource
methods, you could pass a dictionary containing an int and a string.
Then do this:
- (void)setObjectValue:(id)object {
[super setObjectValue:[object valueForKey:@buttonState]];
[self setTitle:[object valueForKey:@buttonTitle]];
}
Getting controls to USE your custom cell can be icky (NSBrowser ack!),
but I don't have much experience with NSOutlineView. If you have
trouble with that, just reply and ask on the list. You should be able
to just call -setCellClass:[MyCustomCell class] on your outline view.

More generally, you could implement the Chain Of Responsibility pattern in the UITextField's direct delegate (the principal delegate), so any number of other secondary delegates could contribute to the overall task, in chain-priority order, and according to which selectors a secondary delegate implements. Since any secondary delegate could also be the principal of its own chain, you have the potential for a tree of delegates. Yes, after careful consideration, the Chain of Responsibility is the approach I went with, and it's working great. Thanks for the suggestion.

You already own _myDocumentView by virtue of the fact that you used
alloc/init, so this extra retain is going to lead to memory leaks

to do).

You are treating _myDocumentView as a pointer to a struct. Since you
declared as _cgImageRef as @public, it will work, it completely
defeats the goal of encapsulation in the language, so you should have
a good reason for doing it. If you can't think of a good reason, then
instead you should set up getter and setter methods for these members:
- (void)setImage:(CGImageRef)image
{
CFRetain(image);
CFRelease(_cgImageRef);
_cgImageRef = image;
}
- (CGImageRef)image
{
return _cgImageRef;
}
An even better design would probably be to not even create getters and
setters and create a method in your view such as
- (BOOL)setImageFromData:(NSData*)data type:(NSString*)type error:
(NSError**)error
{
/* everything in -readFromData goes here
}
Then:
- (BOOL)readFromData:(NSData*)data ofType:(NSString*)typeName error:
(NSError*)outError
{
return [_myDocumentView setImageFromData:data type:typeName
error:outError];
}
It's hard to say without knowing your architecture if that's the
better design, but it is definitely better if your view is the only
thing that uses the imageref, especially since it completely hides the
fact that your view uses CGImages and you are now free to use anything
else that comes along without affecting the rest of your design.
As to why your ivar becomes nil, that's hard to say without seeing
your entire project. But I suspect that if you start using better
encapsulation and other OO principals in your design, your problem
will disappear.

Re: UITextView not updating
Hi,
I run into the same problem with an app for that I decided to set up
my view controllers / views as singletons (and therefore to reuse them).
Views within a scroll view display their previous values if they
become a new value assigned when they are scrolled off (screen or
scroll view bounds - I can't tell).
A fix (very bad for performance) is to set up the view controller as a
delegate for the scroll view and to do somethings like this:
-(void) viewDidScroll {
myTextView.frame=myTextView.frame;
}
It's a bug in UIKit a I always wanted to file but didn't do...

I asked about this earlier and no one seemed the know the answer.
I have a UITextView inside of a scroll view. The textview is
offscreen when the main view loads. So it does not update when data
is loaded in to it. Thus when ever the scroll it is inside moves I
use a standard scrollview delegate method to detect the scroll. Then
execute the code below.
if(scrollView == miniScroll){
for (UIView *childView in onlinePeopleView.subviews)
{
[childView setNeedsDisplay];
}
}
This does not work. setNeedDisplay does not cause it to update and
display the text inside of the textview. What can I do to cause the
text to be displayed? Everything else is set up correctly in IB and
the text size is unaltered. So I know its none of that. If I NSLog()
the contents of the text view it shows that the textview is infact
imbued with the correct text it simply will not display. How can I
force a textview to update it's display?
Thanks

- (BOOL)readFromData:(NSData*)data ofType:(NSString*)typeName error:

{
return [_myDocumentView setImageFromData:data type:typeName

}
Yes, I should do it as above and will. Thanks for the suggestion.
I guess a better way of stating the problem is :
What is the preferred method of associating a view with a document?
This is the fundamental issue for me.

Re: How to display the information in the columns of the table view?
Hi all, In my application, I want to drag the file into the table view. At the same time, display the basic information in the columns of the table view. ...

After killing the connection and running a few tests, I found I was temporarily locked out of the apple list, presumably because it thought I still had an active connection. Anyway it got worse from there but I'll bore you no longer, You caused me significant irritation, and prevented me from getting some emails I was waiting on. Actually.

Dynamic UI with scroll view
I'm writing an app where the number of controls in the UI is dependent on the amount of information to be entered. The scroll view programming guide is not helping either. The only experience I've had with scroll views is the ones that come with other views in IB. If I'm thinking correctly, I can build a view in code (with copying some generic text fields/popup with correct settings in the nib) then set the documentView of the scroll view with this newly created view. But this: (the scroll view is an independent scroll view made in IB) NSLog(@%@, [scrollView documentView]); //outputs (null) [scrollView setDocumentView:[[NSView alloc] initWithFrame:NSMakeRect(0, 0, 500, 500)]]; NSLog(@%@, [scrollView documentView]); //outputs (null) again Also, I'm not too clear on how the frame of this view should work. Should I just make it whatever height I need for all the controls and the scroll view will scroll it? Thanks for any help. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

NSString and regular expressions
I need to do some regex searches on NSStrings, and use capturing groups. Looking online I found some discussions from 2003 referring to MOKit, which hasn't been touched since 2005, and seems to include a lot of stuff I don't care about. Other references to agkit suggest it doesn't support unicode. All of this makes me wonder if there's not a better support in this day and age for regex? I'm surprised not to find it in NSString.

NSWindow reference remains null after window did load
I have a master controller loading a window controller subclass, but for some reason, I cannot get a pointer to the window loaded in the XIB file. I've looked at every connection, and I've also tested the order by of method calls. In the window controller's init: [self window] yields nothing. Likewise in awakeFromNib and windowDidLoad. It's totally mysterious because I have practically identical setups in two other programs, the only difference being that they used nib files and this is xib. But from what I understand, that shouldn't matter. For what it's worth, in the XIB file, the window outlet goes to File's Owner (the window controller subclass). The window contains a table, and (unsurprisingly) [myTable window] also yields nothing. Eventually the window does load, but only in its basic nib-drawn form, ignoring all of the initialization that the controller is supposed to do except for two text fields, which do for some reason get initialized. I've spent hours checking connections and stepping through code. Does anyone have a suggestion where I can look to track down this issue.
