TexfieldCell becomes see through for Borderless Window
Hi, >From the example of RoundTransparentWindow, I made my Application window to show only the Parts drawn and the transparent parts are cleared. This works fine.

Quastion about types in a NSPasteBoard
Hello. I have implemented a drag and drop, and I just wanted to check what I had in the NSPasteBoard on drop... I checked the types from the NSPasteBoard, and the type I declared when dragging is in the second place of the returning array. in first place it's. something like: dyn.ah62d4rv4gu8zuz4xkvw0q2pzrv4fq3pwsvy0g2pqnrka can somebody explain me what's that? can I safely take the 2 type in the array so I can pass it to my AbstractFactory and avoid a bunch of code lines.?

Who can say, without knowing how you've implemented your AbstractFactory? I'd say what you should do is follow the recommended approach for receiving data from a pasteboard, and request the types you're interested in in the order you want them.

Detecting lack of user input system wide.
Hello, What is the correct way to detect that there has been no keyboard or mouse input by the user over a given period of time? Ideally, I'd like my application to stop a timer if there is no activity at all from the user in any application. Think of a time tracking app that stops tracking time after 5 minutes.

Re: Quastion about types in a NSPasteBoard
Hello Graham.
In fact the AbstractFactory has nothing to do with the NSPasteBoard. Im reading
the NSPasteBoard in the NSViewController after it's view has recevied the
performDropOperation:
so this is what Im doing:
NSPasteBoard pb = [sender draggingPasteboard]
NSArray * types = [pb types];
if([types containsObject:DefaultHorizontal]){
...
...
}
else if ( ){
}
else if (){
}
So depending on what I have dragged, Im asking the AbstractFactory to create an
specific object. In the AbstractFactory Im not touching pb. ...
I jsut wanted to see from where is it coming, so I could just do something
like..
CustomObject a = [ createObjectWithName:[[types
objectAtIndex:1] description]];
or something like that instead of doing all those if-else clauses.

Re: Additional action when a view's value changes (Cocoa Bindings)
I think mmalc got me right. Sorry again for my initial mail which was a little
confusing. When I wrote the mail I confused Cocoa Bindings with target/action,
because what I've been doing is, I just connected the selector of one view
TextField) to the takeIntegerFrom IBAction of another one (Stepper) and vice
versa. Actually I'm pretty sure I read this in a book.
Anyways, obviously this is bad practice and I've been doing it "right", I was
just wondering whether there is a more convenient way since I got 4 pairs of
Steppers/TextFields in my app. My action method looks kind of like
if (sender == firstStepper) {...}
else if (sender == secondStepper) {...}
...
In the target controller I don't have IBOutlets for those steppers and
textfields. Those are in another (mediating) controller. Question is whether
there is another way to do this instead of defining outlets also in the target
controller. I guess assigning tags to each stepper/textfield and defining an
enum for them would be an option?
Cheers,
Chris

Yes, but my point was that AbstractFactory is your code, and yours alone, so
whether it will directly accept objects returned from the pasteboard's methods
is known only to you, so it's not a question anybody else can answer.
> NSArray * types = [pb types];
> if([types containsObject:DefaultHorizontal]){
You shouldn't be looking for what types the pasteboard has like this. You
should be asking it whether it has the types you want, in the order you want
them, using -availableTypeFromArray:
Given those types something will have to map those to the classes your abstract
factory makes. A bunch of if...else clauses is one way, but there smarter ways,
like having a dictionary that maps type -> class.
e.g.
NSString* myType = [pb availableTypeFromArray:[NSArray
arrayWithObjects:@"first_choice", @"second_choice", nil]];
Class theClass = [classMapDictionary objectForKey:myType];
if( theClass )
{
id object = [[theClass alloc] init];
}
If you are targeting 10.6 or later, the pasteboard supports multiple objects
and there are new APIs to get them. But for 10.5 and earlier, the pasteboard
can only hold one object, albeit in a different number of representations. If
the data is private to your app, you can get around that by passing an array of
objects in some fashion, but for data passed between apps, you're pretty much
stuck with the standard types unless yours and the other app agree on some
common protocol.
But to get back to your original post - anything you see on the pasteboard you
don't recognise is none of your business - it's probably data private to the
app where the drag started.

I was thinking in something like this whe getting the type from the pasteboard.
but didn't know... I guess I will ask in the Obj-c list about this..
then also Im gonna change the way I get the types form the pb as you suggested.
Im developing for 10.6 and on... but so far Im placing only one Data type in
the PB,.. who knows if I may need to put more in a future...
Ok Im gonna leave that weirdo type alone... hehe
Thanks for the help, as always very useful.

I noticed that the NSOutlineView's trackMouse method is only called when you click-and-drag inside the tracking areas of the cell (in this case, the info button). In other words, clicking anywhere else in the cell won't trigger the trackMouse method. Why does it happen this way? I'm starting to think that the trackMouse method is related to the NSTrackingAreas... but I'm surely wrong.

I guess assigning tags to each stepper/textfield and > defining an enum for them would be an option? In general I've found it's a false economy to avoid outlets for all controls - you'll want them sooner or later so may as well give everything an outlet just as a matter of habit. The target controller should be the controller with these outlets. It's OK to have multiple tiers of controllers, but make sure each one has a clearly defined role. Sounds like you have not defined a clear role for each controller and each is doing part of the job of the other. Multiple controllers would usually be arranged in series, not in parallel. Don't use tags to identify controls - that's not what they are for and there are far more elegant ways to handle this. To avoid the problem of keeping a stepper and a textfield in synch, you generally want to include the relevant property of your data model within the complete feedback loop that is created: stepper -> controller(s) -> data model -> change notification -> controller(s) --> text field text field-^ |-> stepper If you organise things this way then anyone else that changes that property of the data model also will cause your UI to update correctly (Undo, for example, or a different UI on the same property). This is precisely what bindings does, but you can do the same using target/action as well though it's a bit more work. e.g. You can set up the controller to observe the property changes using KVO (or some other means, such as notifications or a direct protocol of your own devising) and then respond to those changes by setting the relevant controls' values through their outlets. For new code, bindings is the way to go - it uses KVO internally and is the least work to set up. --Graham ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Question about touchesBegan
I'll elaborate a little more. I have a main view with some source buttons (UIButton) at the top. When I click one, I bring up a radio style tuner bar in a subview (animates up from the bottom). I am using touches to move the "pointer" in that subView. Works great, however because the subView is detecting touches for the whole subView - it prevents touches on those buttons in the main view.

Yup - setting the bounds is working. So I can have touches in my main view and also in the sub view. Coming from Flash AS3, this stuff seems so complicated in comparison.

Using CATransition for large views
I'm using CATransition to swap views with [[view animator] replaceSubview:oldView with:newView] The issue here is that when swapping between views with a large amount of content (e.g. a collection view with hundreds of items) there is a very noticeable 1-2 second delay before the animation starts. This doesn't seem to be an issue with CATransition itself, as using replaceSubview:with: without the animator proxy still has the same issue. Is there another way in which I could still use CATransition, but be able to swap large views fast and smooth?

Not necessarily --- if you just happen to click in the little IB icon in the window title bar, you'll start a drag of that icon . . . I just tried your experiment --- that is, place a UILabel halfway up out of the view (essentially 'under' the title bar), and I'm able to drag the window/view around with no problem at all *providing* I start the drag outside of the little IB icon . . .

The Process Manager isn't even part of Carbon.framework, it's in ApplicationServices.h framework. It's lineage is pre-OS X of course.

There is a very much in passing comment in 'Internationalising Programming Topics' guide for Cocoa. Note: It is recommended that you save strings files using the UTF-16 encoding, which is the default encoding for standard strings files. It is possible to create strings files using other property-list formats, including binary property-list formats and XML formats that use the UTF-8 encoding, but doing so is not recommended . . .

Ah - wait! I am using UTF-8 for the files in the Xcode Project. This makes it much easier to handle them in SCM systems etc. But Xcode automatically converts the strings files into UTF-16 when copying them into the final App bundle. I'm not sure this was always the case, though.

Problem with missing symbol
Hi,
I am trying for some specific reason to access a private attribute and make it
public for my need with the following code
in the .h
#import
@interface NSStatusItem (hack)
- (NSRect)hackFrame;
@end
in the .m
import "NSStatusItem+hack.h"
@implementation NSStatusItem(hack)
- (NSRect)hackFrame
{
return [_fWindow frame];
}
@end
void Init_nsstatusitem() { }
When compiling with the following I get
gcc-4.2 -o NSStatusItem.bundle -bundle -framework AppKit NSStatusItem+hack.m
Undefined symbols:
"_OBJC_IVAR_$_NSStatusItem._fWindow", referenced from:
-[NSStatusItem(hack) hackFrame] in ccGpP6n1.o
ld: symbol(s) not found
collect2: ld returned 1 exit status
This use to work in 10.5 .. I am using 10.6 and this is not linking due to
missing symbol. What I do not get, is that the _fWindow is still an attribute
in the NSSStatusItem...
any idea?
Thanks

The .strings files are actually a special case of plist files. There are three supported formats: first, the special .strings file format, which is UTF-16 plain text consisting of lines of "key" = "value"; pairs with optional comments; second, the XML plist format; third, the binary plist format. The .strings file format is the recommended format for .strings files. If you use this format, you should use UTF-16 with a BOM. If you use the XML plist format, the encoding specification is as per XML, but almost always one would use UTF-8. If you use the XML or binary plist format, the contents must be a dictionary of strings.

I am trying to create a small item in the status bar, which when I click, I can
show at a glance a small calendar... kind of like how Gnome does it. Really
convenient and better than loading the full dashboard at times.. Anyway I using
rubycocoa and this is the code I am trying to have to work.
The hackFrame method was returning the result of a the [ _fWindow Frame]
method. But if I cannot access the _fWindow since it is private, not sure
how else I can
I will look at those methods then. But this is what I am up to (using RubyCocoa)
statusbar = NSStatusBar.systemStatusBar
@item = statusbar.statusItemWithLength(NSVariableStatusItemLength)
image = NSImage.alloc.initWithContentsOfFile("cal.png")
@item.setImage(image)
@item.setAction :clicked
calendarController =
CalendarController.alloc.initWithPosition(@item.hackFrame)<== I need the
frame here

I should clarify that all I am trying to do is to get the initial position of
the new item on the status bar to position a small window (like a contextual
menu) right under that icon when clicking on it.

dynamically create/remove IB elements and instance vars?
Hi, I just wrote a basic little cocoa app to test my knowledge after going through Apple's Currency Converter tutorial... I made two text fields, and when you click a button, it combines the two words together and displays them in a label. I would like to expand on this and make it a little more interesting and challenging, but I don't know how to do what I am thinking-- which is: Create a button which will insert a new label/text field. This action also needs to dynamically generate an instance variable in my model file for the text of the new textfield, as well as generate an IBOutlet in my controller. ... I know how to do this immediately with javascript-- but.. objective-c and xcode... no clue! Any suggestions? Patrick J.

It would be a lot easier than creating a window - which contains an NSView, if it's Cocoa - and working out where to show it; all that work is done for you.

In the exact terms you've used, this is not a pattern you're likely to use in any practical application. Although Objective-C is in many senses a dynamic language, this particular kind of dynamism is not usual in most applications. If there's only one "new" label, then you might as well go ahead and design it into your code and your interface to begin with (even if it's hidden initially). If there might be an arbitrary number of new labels to show in the interface, you might use an NSArray or NSDictionary instance variable to hold the values, and a NSTableView to display them. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

String attributes in the iPhone SDK
I use the following code to determine the height and width of a string in the Snow Leopard version of an app NSMutableDictionary *textAttributes = [[[NSMutableDictionary alloc] init] autorelease]; [textAttributes setObject: [NSFont fontWithName: @"Garamond Bold" size: 24] forKey: NSFontAttributeName]; [textAttributes setObject: [NSColor blackColor] forKey: NSForegroundColorAttributeName]; NSString *text = [NSString stringWithFormat: @"%d", h]; NSSize textSize = [faceText sizeWithAttributes: faceTextAttributes]; x -= faceTextSize.width / 2.; y -= faceTextSize.height / 2.; I'm tearing my hair out trying to figure out how to accomplish the same thing in the iPhone SDK. Can anybody help me? Charlie Dickman 3tothe...@comcast.net ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

I found what the problem was. The hitTestForEvent:inRect:ofView: method had to be overridden to return NSCellHitTrackableArea. Problem solved.

Binding an Array of Dictionaries
I have a window with an NSTableView which is bound to an NSArrayController which has as content an NSMutableArray called "theArrayOfDictionaries". Works fine. "theArrayOfDictionaries" contains NSMutableDictionaries. So I added another NSTableView to my window, bound to an NSDictionaryController, which has it's content bound to NSArrayController.selection. But the documentation says about selection: "proxy object representing the receiver’s selection". And it's no surprise that I get an exception: "Cannot create NSDictionary from object [...] of class _NSControllerObjectProxy" Well, everything behaves as documented - no reason to complain. But: how to I populate my NSDictionaryController with the NSMutableDictionary currently selected in my NSArrayController? And also: make sure that any changes done in this current dictionary (the NSTableViews will be editable) get back into "theArrayOfDictionaries"?

[ myWorkSpace openURL: myurl ] is leaking. Why??
Hi all,
This is a very simple code. And it is always leaking.
-(void)awakeFromNib {
NSAutoreleasePool* pool = [ [NSAutoreleasePool alloc ] init ];
NSWorkspace* ws = [NSWorkspace sharedWorkspace];
NSString* tempUrl = @"http://www.google.com";;
NSURL* myurl = [NSURL URLWithString:tempUrl];
* [ws openURL:myurl]; * *// Here NSCFDictionary is leaking 64 bytes
twice. (shown by instruments)*
[pool release];
}
leaks shows:
Process 1605: 8513 nodes malloced for 1063 KB
Process 1605: 2 leaks for 128 total leaked bytes.

I must be missing something here.
Can anyone point what is wrong here.
Advanced thanks.
