Who is "self" here? Is it the tab view item view? If so, does the tab view item
know that you are using a custom subclass? Lastly, what is the origin point (to
make sure it isn't being placed outside the viewable area)?

Does this code work when you substitute NSPDText with a canned cocoa UI object?

Re: Updating NSMenu while it's open
Yes. I am facing the same problem. I am updating the menu in performSelectorOnMainThread. If the menu is kept open without any event then there is menu refreshing issue ie. sometimes some items will be shown twice. When I move the mouse over items then it will update. But, when the menu is open and mouse is still then the menu won't update. Is there a way to update the menu while it's open without any mouse movement like System WiFi menu?

I agree. This should not happen, but here is my original code:
-(NSString*)formattedDate:(NSDate*)aDate{
NSDateFormatter * formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"mm-dd- hh:mm a"];
NSString * dateString = [formatter stringFromDate:aDate];
return [self stringWithSentenceCapitalization:dateString];
}
and it produces the incorrect format.
It is called like this:
[weathervane formattedDate:[timer fireDate]];
[timer fireDate]
returns a date in this format:
2012-04-20 18:23:43 +
I've also rebuilt the revision of the source for the old build that I have and
it produces the same flawed results.
In any case, I'll edit the global prefs and see if it makes a difference. I
really hope that I made an error somewhere. Thats a problem I can fix.

self is the custom class of the view that is owned by the tab view item.
you do not use a custom class for the tab view item
the origin is 10,25

This may be because the format is invalid, although I wouldn't have thought so.
It should be: @"MM-dd-yyy hh:mm a". Might be worth a try.
For giggles, what does -[formatter formatterBehavior] return? Does setting it
explicitly to NSDateFormatterBehavior10_4 change anything?

When no one replies, it's usually the latter, but it might be something easy.

Displaying history - potential ways to do it
Hi, Am a newbie to iOS development. I want to display the DB history i.e. the changes the users make to a specific critical table in the DB, from bottom-up, i.e. the first update appears bottom-most ...something like ... ... Apr 10th - Changed 'status' field from 'boolean' to 'char' Apr 5th - Granted Joe access to the table Apr 2nd - Added a column to the table And I would like to display it in a fancy way...something like the timeline in Path app if I should say a recent example. One possible way I see to do this is to use UITableViewCell. Is there any other way to do this? Which is recommended/apt?

Is NSPDText a subclass of NSView? If so, I guess it should work, but it's
unusual to have a view be the owner of a NIB. You are mixing view and
controller layers, so you may want to consider a different design just to
clarify the roles of objects.
It appears you expect the content of the NIB to be visible. But, you add m_text
as a subview and it has no subviews; the fact that m_text is the owner of the
NIB does not cause views in the NIB to be added automatically to the owner. if
m_text has an outlet to a view, that will be connected, but then m_text must
add the view to itself as a subview. Try this quick experiment: in NSPDText,
override -drawRect and scribble in the view, such as (written in Mail):
- (void)drawRect:(NSRect)rect {
[@"Hello World" drawAtPoint:rect.location withAttributes:nil];
}

Redrawing overlay views
I have a window which owns a webview over which I place buttons (in their own
subviews) where the user has clicked. However, because they are not part of
the webview's hierarchy of objects, when the window is resized the webview
content will likely reflow. I therefore need to reposition the buttons. I have
methods which annotate the DOM and which cache references to the nodes the user
has selected. I am thinking to walk the cache of nodes and redraw the button's
views at the new location of the corresponding DOM element. I am halfway
through implementing this strategy but would be interested to hear other
opinions of how this might be achieved.
Below is some of the code I have in the works which responds to the window's
windowDidResizeNotification in the windowController and instructs the webView
to walk the cache of user-selected DOM nodes. At present I cannot seem to
recall the DOM nodes from the dictionary in which the code caches them.
#import
#import
#import "RSWebView.h"
//
// this controller is both windowController and webview frameLoadDelegate
@interface RSTrixieController : NSWindowController < NSComboBoxDataSource,
NSComboBoxDelegate >
@property (retain) IBOutlet RSWebView * webview;
- (void) refreshWebviewOverlay:(NSNotification*)nota;
@end
@implementation
@synthesize webview;
- (void)windowDidLoad
{
[super windowDidLoad];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(refreshWebviewOverlay:) name:NSWindowDidResizeNotification
object:[webview window]];
}
- (void) refreshWebviewOverlay:(NSNotification*)nota {
[[self webview] repositionLocatorViews];
}
[…]
@end
Then from the webView which responds:
@implementation
@synthesize boundingBox;// trivial view which draws it's outline
@synthesize locators; // mutable dict - button-hosting views -
keyed-alike to taggedNodes
@synthesize taggedNodes;// mutable dict - DOMElements adjacent -
keyed-alike to locators
- (void) repositionLocatorViews {
// clean up
[self removeBoundingBox];
for(NSString * idtag in [taggedNodes allKeys])
{
DOMElement * node = [taggedNodes objectForKey:idtag];
RSBoundingBox * bbox = [[RSBoundingBox alloc]
initWithFrame:[node boundingBox]];
NSRect newBox = [self flipBoundingBox:[bbox frame]
fromWebView:self];
[bbox setFrame:newBox];
RSLocatorViewController * lv = [locators objectForKey:idtag];
[[lv view]setFrame: [self frameRelativeTo:bbox]];
}
}
- (NSRect) flipBoundingBox:(NSRect)htmlBox fromWebView:(WebView*)webView {
NSRect bounds = [[[webView window] contentView] bounds];
float newY = bounds.size.height - htmlBox.size.height -
htmlBox.origin.y;
return NSMakeRect(htmlBox.origin.x,newY,htmlBox.size.width,
htmlBox.size.height);
}
- (NSRect) frameRelativeTo:(RSBoundingBox*)bbox {
return NSMakeRect(bbox.frame.origin.x-20, bbox.frame.origin.y +
bbox.frame.size.height - 20, 20, 20);
}
- (void) removeBoundingBox {
if(nil != boundingBox)
{
[boundingBox removeFromSuperview];
boundingBox = nil;
}
}
[ … ]
Any thoughts and suggestions welcomed.

So, I solved it as follows. I created a deleteObjects IBAction in my
AppController class invoked by the delete menuItem. To remove the objects, I am
more or less following the code in Hillegass' book, chapter 15 on NSAlerts.
In this example, the line
[employeeController remove: nil] is used to remove the selected objects
(employees)
However in my app it didn't remove anything (the code was called, though).
After some searching, I ended up doing the following:
for (Employee *employee in employeeArrayController.selectedObjects)
{
[[self managedObjectContext] deleteObject: employee];
}
It seems to work, but just to be sure I am checking here to see if this is
indeed the correct approach?
Thanks,
- Koen.

It's *a* correct approach.
It's not clear what went wrong with '[employeeController remove: nil]', but
that's a completely separate problem. For example, if you left the array
controller in Class mode rather than Entity mode, 'remove:' won't update Core
Data properly. Also, take a look at the class reference documentation for
NSArrayController (for the 'removeObject:' method) for a discussion of how to
configure the array controller's deletion behavior for Core Data.

There are only global variables (even if they are declared between @implementation and @end of a class), and instance variables (declared using @property and @synthesize, or declared between the curly brackets of the class. So if you google for "global variable", or "instance variable" you might find better information. But reading on, I think your main confusion is memory management. I presume you have not turned on ARC or the garbage collector, right? > Now, within a method, am setting this value to the date from a DatePicker > as: > > *fromDate = [datePicker date];* "date" does not contain "retain", "copy", "new" or "alloc", so it gives you an object you do not own. Usually an autoreleased object, which stays around until your method returns or thereabouts, but maybe it's just owned by this date picker. fromDate contains the address (think "building number" of one building in a street) of that particular date. Now when your date picker gets destroyed (e.g. you close its window) or when its value changes, the date picker releases the old date (and creates a new one in the case of the change). (Going with a house metaphor, this means it tears down the house whose house number you remembered, and forgets its house number, then goes to build another house containing the new date) Now, the problem is, your fromDate variable still contains the address of the old, destroyed date. So when you later use it in another method, you end up not at a date object, but in a random memory location (an empty building site, if you want). > Soon after the above assignment, I print its value into the log & it works > fine. > > *NSLog(@"From Date: %@", fromDate);* > > Now, when I use NSDate's value in another/different method, the value's > gone!

There are lots of examples around. That's wrong. There are no properties on classes. There are only properties on instances of classes. It helps to think of a class as a blueprint. When you create a new object of that class (called an "instance" by geeks), you actually build, say, a radio according to those blueprints. When you destroy the radio because you no longer need it (OK, this is where the analogy becomes more violent and wasteful than I intended), the blueprint still exists, and you can create a new instance according to these plans, or several at the same time. Now, the blueprint (i.e. the @interface ... @end and @implementation ... @end in your source code) say that a radio has a "current frequency" property, a "volume" property, maybe even a "date" property if it has a built-in clock. But that *does not* mean that the *class* has a current frequency, volume or date/time. When you create a new radio from the blueprints, it will have those things. When you set the clock on your radio in San Francisco, it will not change the date on my radio in Munich. Each object/instance/radio gets its own property. OTOH, when you create a global variable like your fromDate, there is only one for your entire program. If you change the clock in San Francisco to be correct, it will suddenly be wrong for me in Munich. Now that's not necessarily wrong, if you intended to build a radio with a "San Francisco Local Time" clock, mind you. It just depends on what you are actually trying to do ... ?

Yes I did read that, but the suggestion there to enable "Deletes Objects On Remove" also didn't work. I suspect what is happening is that I also maintain an NSTreeController to control the source list on the left side, and that is the controller that is bound to the MOC. The content set of myArrayController is bound to myTreeController. In any event, removing the objects from the MOC directly works seamlessly, it also updates the source list, etc. - Koen. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Guidelines on using NSJSONSerialization
What's odd is that I check the annotation array for nil termination earlier on and to alert me. No alerts. But I do a check when rebuilding the array to ignore nil results and that exports fine. I'm still thinking that nil termination is creeping in there but all I have inside are locations with the coordinates as a struct of doubles, the address and the sub address as NSStrings. Yeah, so from what you said, there's the CLlocation object in every annotation object that contains the struct of doubles. I knew I should have handcoded the export to JSON. Hours wasted. So many hours. On Apr 22, 2012, at 11:58 AM, Fritz Anderson wrote: > On 22 Apr 2012, at 6:51 AM, Uli Kusterer wrote: > >> It could be a CFArrayRef.

Problem with capturing view contents
Hi, I have a view I am trying to capture using the following code:
NSBitmapImageRep *rep = [view bitmapImageRepForCachingDisplayInRect:[view
bounds]];
[view cacheDisplayInRect:[view bounds] toBitmapImageRep:rep];
My view coordinates in a typical test case are as follows:
"01_frame" = "{{0, 0}, {350, 190}}";
"02_bounds" = "{{-98, -95}, {350, 190}}";
The image rep created is the right size, but the contents are drawn up and to
the right in the image rep (by 98,95 pixels).
If I instead use the frame, the contents are in the right place in the image
rep, but it only includes the portions of the image with positive x and y
values (bottom right seeing as it's a flipped view).
If I create an image that is bigger by the amount of the negative origins of
the bounds, the entire thing is drawn, but then I would need to crop the image
afterwards, which would be very messy and memory hungry since my views can get
pretty big.
I tried applying an affine transform before grabbing it, but that made no
difference.
So is it possible to capture views where the bounds go into the negatives, and
if so, how?
TIA
Gideon

NSPopover ~ resize to match content?
I'm trying to make a popover view resize to fit the content-of-the-moment.
This is probably trivial and I have being over thinking myself into
complications.
I have three classes of information to display in turn in a popover. The user
clicks a segment control to advance and may return if she wishes. My window
xib contains the popover view and three differently sized 'client' views which
are swapped in as needed. Great, works like a charm.
However I cannot for the life of me cause the popover 'host' view to resize.
When I dump the dimensions to NSLog the outer view frame reports the correct
(resized as I specified) dims. but the popover has not been resized. The
numbers do not match the picture.
What am I missing? Some code:
- (void) showPanel:(NSView*)panel {
// guard
if(!panel) panel = actionPanel;
[self setActivePanelWidth: panel.frame.size.width];
[self setActivePanelHeight: panel.frame.size.height];
NSLog(@"%s- [%04d] %@: %0.2f", __PRETTY_FUNCTION__, __LINE__, [panel
className], panel.frame.size.height);
NSRect newFrameSize = self.view.frame;
newFrameSize.size.height = popoverHeader.frame.size.height +
activePanelHeight;
NSLog(@"%s- [%04d] %@: %0.2f", __PRETTY_FUNCTION__, __LINE__,
[self.view className], self.view.frame.size.height);
[[self view] setFrame:newFrameSize];
if( currentPanel == nil)
{
[[self view] replaceSubview:[self placeholderBox] with: panel];
}
else {
[[self view] replaceSubview:currentPanel with: panel];
}
// a custom category on NSView
[panel setFrameTopLeftPoint: popoverHeader.frame.origin];
currentPanel = panel;
[locator setCurrentPanel: panel];
[popover showRelativeToRect:[locator bounds] ofView:locator
preferredEdge:NSMaxXEdge];
}
Any help appreciated. Thanks.

Re: addsubview
Hi koko,
This could be anything from "the view is added to the wrong subview" to "the
view has a frame that moves it outside of its' parents bounds" to "the view is
visible but does not draw anything."
Two powerful tools that will help you with debugging:
- Run with NSShowAllViews set to YES
- Use the _subtreeDescription method to get a list of all your views and where
they are.
A web search will show you how to do either of those if you're not sure.
Hope that helps.

Good questions.
As an experiment, in the same method in which I create and add the subview
which is not displaying I create an NSButton using the same frame as for
the subview. I add the NSButton and it displays.
So, I am sure the NSTabviewItem view is correct.
As to the subview, I added a delegate method for when the tab is clicked.
Breaking there and dumping the subviews I see my subview in the view
hierarchy.
This seems such a trivial task that I am quite puzzled.

Losing attachments when saving rtfd
Dear programmers, Trying to save an RTFD from an NSAttributedString with attachements. The text saves; the images don't... I've been scouring the web but can't seem to figure out what's wrong. I have a NSAttributedString with attachments. I check that the string really has the attachments by using setAttributedString to the textstorage of a NSTextView, and voila, there it is. But I can't seem to save the attachment. This is what I'm trying: //this is a category I found on the interwebs myimagets = [[NSTextAttachment alloc] initWithAnImage: myimage]; //get doc string //replace with the attributed string myattstr = [NSMutableAttributedString attributedStringWithAttachment: myimagets]; //stick on a little text at the end to see how it handles both... addon = [[NSMutableAttributedString alloc] initWithString: @"and here's the extra bit"]; [myattstr appendAttributedString: addon]; //this is my test to see if the attachment is really there: it works! [[myTextView textStorage] setAttributedString: myattstr]; //here's what fails: myfw = [myattstr RTFDFileWrapperFromRange: NSMakeRange(0, [myattstr length]) documentAttributes:nil]; [myfw writeToFile: [@"~/Desktop/outfile.rtfd" stringByExpandingTildeInPath] atomically:YES updateFilenames:YES]; What's created is an rtfd with only the rtf file in it and no images Thoughts?

Re: Updating NSMenu while it's open
Yes. As I answered before, you have to get things scheduled in the right
runloop mode. But once you do, it's quite easy:
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification {
NSStatusItem *item = [[[NSStatusBar systemStatusBar]
statusItemWithLength:24] retain];
[item setImage:[NSImage imageNamed:NSImageNameApplicationIcon]];
[item setEnabled:YES];
NSMenu *m = [[NSMenu alloc] init];
[item setMenu:m];
NSTimer *t = [NSTimer timerWithTimeInterval:1.0 target:self
selector:@selector(updateMenu:) userInfo:m repeats:YES];
[[NSRunLoop currentRunLoop] addTimer:t forMode:NSDefaultRunLoopMode];
[[NSRunLoop currentRunLoop] addTimer:t forMode:NSEventTrackingRunLoopMode];
}
- (void)updateMenu:(NSTimer *)t {
NSMenu *m = [t userInfo];
NSString *s = [[NSDate date] description];
NSMenuItem *i = [[NSMenuItem alloc] initWithTitle:s action:nil
keyEquivalent:@""];
[m addItem:i];
[m update];
}
Run that, open the poorly-iconed status item, and don't touch your mouse.
Yes, this code is terrible and leaks and all that. It's just to illustrate the
point.

Re: How to set the foreground and background colors of selected text in a field editor (NSTextView)?
Thanks for the suggestion, Kyle. I subclassed NSTextViewCell and implemented -setUpFieldEditorAttributes. My apologies to anyone who initially followed this thread and has had to wait till now for a solution/outcome. This became a low-priority issue almost as soon as I posted it and I only got back to it two days ago. -Michael On Apr 10, 2012, at 3:09 PM, Kyle Sluder wrote: > On Apr 10, 2012, at 11:29 AM, Stephane Sudre wrote: > >> Allowing rich text, subclassing NSTextField and add some methods from >> NSTextView did not work so far. > > Subclassing NSTextField and implemented -setUpFieldEditor didn't do the trick? > > --Kyle Sluder ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

The code you posted is pretty bizarre. It might work, but there's certainly not
enough to go on for others to help you.
What is NSPDText? Is that a class of your own (if so, it should NOT be prefixed
'NS', that's Apple's reserved prefix. If it's supposed to be a Cocoa class, I
have never heard of it). Using a view as 'Files Owner' for a NIB is very
unusual and unconventional. It might work, but then again, it might not - it's
not standard practice, so there won't be a large body of code to compare it
with.
Have you tried simply instantiating NSPDText in a window and seeing whether it
in fact does draw anything? Perhaps the reason nothing appears is because that
class is broken.
What is the reason for not simply adding your view to the tab view in IB?
Again, that's what I and probably most Cocoa programmers would do.
The problem you seem to have (not just here, but in most of the cries for help
you post) is that you don't take the time or trouble to learn how things are
typically done, but half-understand it and then write a screed of code based on
that improperly understood concept. You also then ignore advice to go back and
do it properly and persist in doing it your (incorrect) way. For example, using
the NSBundle method above is rarely done. Instead, you conventionally use a
higher level class such as NSVIewController or NSWindowController that loads
the nib for you. I'm not saying it's wrong, but it is unusual, and it's
certainly symptomatic of an approach that will lead to buggy, difficult to
maintain code that others will have little chance of helping you with, because
it's "out there" in uncharted territory.
There is a very strong streak of the bad workman blaming his tools here.

Except that due to the way the Menu Manager works, you can't use view-based menu items to perfectly imitate standard menus, so this is probably not an option for your app. You could reimplement the entire thing as a window, but that wouldn't play nice with accessibility. --Kyle Sluder ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
