Avoid smooth scrolling when scrolling programmatically
I need to set the scroll position of my NSScrollView programmatically, and I don't want it to scroll smoothly (if the user's "smooth scrolling" preference is on). I can't find a way how to do that. Calling scrollPoint: on my document view results in smooth scrolling. I thought that removing the scroll view from its superview before and adding it back afterwards would prevent this, but it doesn't. I also tried calling setBoundsOrigin: on the content view instead, but it also results in an animation (although only sometimes, and in different cases than with scrollPoint; I haven't been able to figure out the details yet). I guess I could mess with NSUserDefaults, turning off smooth scrolling before calling scrollPoint and restoring it to what it was before afterwards, but this seems like a hack to me. Any other ideas? -- Stefan Haller Berlin, Germany http://www.haller-berlin.de/ ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

how to get baseline info
I have a subclass of NSTextView which does:
- (void)setUpData
{
[ [ self textStorage ] setAttributedString: someAttributedString ];
// uses self.usedFont
NSLayoutManager *layoutManager = [ self layoutManager ];
baselineOffset = [ layoutManager defaultBaselineOffsetForFont:
self.usedFont ];
lineHeight = [ layoutManager defaultLineHeightForFont: self.usedFont ];
}
- (void)drawRect:(NSRect)dirtyRect
{
[ super drawRect: dirtyRect ];
for( NSUInteger line = 0; line < NBR_OF_LINES; line++ )
{
CGFloat bax = lineHeight * line + baselineOffset;
[ [ NSColor blueColor ] set ]; // base line
[ NSBezierPath strokeLineFromPoint:NSMakePoint(
NSMinX(dirtyRect), bax )
toPoint:
NSMakePoint( NSMaxX(dirtyRect), bax )
];
};
}
This works, because currently all lines use the same font.
But how would I handle the more general case, where each line might contain
several and/or different fonts?
Kind regards,
Gerriet.

NSScanner to find multiple occurrences of a prefix?
Hi all,
I am trying to use NSScanner to change camel cased strings into
underscore delimited strings, e.g featuredListingId to
featured_listing_id
I have worked our how to use NSScanner to achieve this, consider my
implementation (implemented as a NSString category)
- (NSString *) delimiterSeparatedWords
{
NSScanner *scanner = [NSScanner scannerWithString:self];
NSString *prefix = nil;
NSString *suffix = nil;
[scanner scanCharactersFromSet:[NSCharacterSet
lowercaseLetterCharacterSet] intoString:&prefix];
[scanner scanCharactersFromSet:[NSCharacterSet letterCharacterSet]
intoString:&suffix];
NSString *fieldNameString = [NSString stringWithFormat:@"%@_%@",
prefix, [suffix lowercaseString]];
return fieldNameString;
}
obviously it only addresses the first occurrence of a capital letter.
Can I ask NSScanner to keep looking for multiple occurrences?
Thanks for your time.

Use something like
while (![scanner isAtEnd])
{
// your code
}
And be careful to consider all possibilities so you can't get an infinite
loop.___

Problem with NSAppleScript execution
Hi list,
I'm trying to run a simple Apple script, that gets the text from the frontmost
application. Basically it simulates cmd+c click. It checks whether the
clipboard is empty and if it is, it simulates the cmd+a and then cmd+c again.
It doesn't work consistently. Sometimes it works and sometimes - doesn't. The
interesting thing is that it doesn't return any error. Like the script runs and
even returns a descriptor, but I see the data is 0 bytes there.
Same script in the ScriptEditor btw works just fine :(
Did somebody bump into such a thing before?
Here is the code, which I use:
NSString *scriptStr = @"set the clipboard to \"\"\n"
"tell application \"System Events\" to keystroke \"c\"
using command down\n"
"delay 0.1\n"
"set selected_text to (the clipboard as text)\n"
"if length of selected_text = 0 then\n"
"tell application \"System Events\" to keystroke \"a\"
using command down\n"
"delay 0.1\n"
"tell application \"System Events\" to keystroke \"c\"
using command down\n"
"delay 0.1\n"
"end if\n"
"set selected_text to (the clipboard as text)\n"
"return selected_text";
appleScript = [[NSAppleScript alloc] initWithSource:scriptStr];
NSLog(@"appleScript = %@", appleScript.source);
NSString *returnString = nil;
@try
returnDescriptor = [appleScript executeAndReturnError:&errors];
if (errors) {
NSArray *all = [errors allValues];
for (int i = 0; i < [all count]; i++)
NSLog(@"ERROR ** %@\n", (NSString *)[all
objectAtIndex:i]);
}
if (returnDescriptor != NULL) {
if (kAENullEvent != [returnDescriptor descriptorType]) {
if (cAEList != [returnDescriptor descriptorType]){
NSData *aData = [returnDescriptor data];
if (aData && [aData length] != 0) {
returnString = [[[NSString alloc]
initWithCharacters:[aData bytes]
length:[aData length]/2]
autorelease];
}
}
} else {
NSLog(@"%@", @"Couldn't process AppleScript");
}
}
NSLog(@"copied string = %@", returnString);
}
@catch (NSException * e) {
NSLog(@"exception = %@", [e description]);
}
return returnString;
The returnDescriptor isn't NULL, but has 0 bytes of data. It's like something
doesn't work there and the script isn't performed.
More than that, when I run same script from Script editor, it works perfect. Is
it a known problem or do I do something wrong?
Thanks,
Nava

Disable autosave in place for a particular uti / filetype?
Is there any way to turn off 10.7's autosave in place for a particular uti/file type? Or maybe turn it on for a single file type? Here's my use case: I've got an image editor which can edit multiple types of files (png, jpeg, etc). Autosave is great for for its native format (.acorn) which is lossless and can preserve layers. But for something like a jpeg, which is a lossy format, autosave in place is problematic. Open up the image, edit, and it saves. And when you undo to the original state, autosave kicks in- but the saved file doesn't go back to it's very original state. It's compressed again, which is going to cause image degradation over time. If I return a lossless uti in - (NSString *)autosavingFileType, the original jpeg will be written with data that isn't a jpeg, which is problematic as well. I realize that having autosave turned on for a single file type is dumb and will be confusing for the user- but I'm just looking for ideas at this point. thanks, -gus -- August 'Gus' Mueller Flying Meat Inc. http://flyingmeat.com/ ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

any way to know where a UIBarButtonItem has been drawn?
I have a toolbar with items on it. One of them is a trash can. When I delete something from the main screen I'd like it to 'minify' towards the trash can, well I think I would, I have to see what it looks like and see if the effect is as nice as I hope, I want to draw attention to where the 'thing' has gone and this seems like a reasonable animation to try. However .. I can't figure out what the frame for the UIBarButtonItem is .. it's on a bar with items which change, some flexible space etc, so it's not a fixed offset from either end of the the thing, and I can't find an API which tells me what the frame is for a given item.

Sometimes the obvious answers are… > not so obvious :) Probably because it's not the "best" solution. We have the same issue in our apps, where we read and write to a filetype, but the reading and/or writing process might be lossy (OPML in OmniOutliner is a prime example). I believe the expected behavior would be to get an untitled document with the lossily-imported file contents. I believe you get this behavior for free if you set the Role to "Viewer" in your UTI declaration. --Kyle Sluder ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

I can't find a frame either, but the bar will give you an array of items, and
assuming all the items are UIBarButtonItem, you can iterate over the array to
get their widths. From that you can get a good enough rectangle for visual
purposes. Here's what I'd start with (composed in Mail, untested):
- (CGRect) barButtonFrame: (UIBarButtonItem *) aButton
{
// Assumes you are holding a UIToolbar in self.toolbar.
// Assumes everything in the toolbar responds to -width
// (i.e., UIBarButtonItem, which includes spacers).
// The toolbar observes an inset for the first item.
// Figure out the inset empirically, and adjust BAR_MARGIN accordingly:
#define BAR_MARGIN 4.0
BOOLfound = NO;
CGRect buttonFrame = self.toolbar.bounds;
CGFloat totalWidth = 0.0;
for (UIBarButtonItem * item in self.toolbar.items) {
if (item == aButton) {
// Found it.
buttonFrame.origin.x = totalWidth + BAR_MARGIN;
buttonFrame.size.width = item.width;
found = YES;
break;
}
else
// Still looking.
totalWidth += item.width;
}
return found? buttonFrame: CGRectZero;
// The rect is in the coordinates of self.toolbar.
// Convert to self.view coordinates (or whatever) for the animation.
// Check for CGRectZero (button not found). There's an argument to
// be made that this method should raise an exception if ! found.

Imagine a master-detail interface with a master list of "documents" and a detail view showing one document.

The typesetter can be obtained via -[NSLayoutManager typesetter].

Well, then, rather than hard-coding it, include that .scpt file in your
project, and in your Copy Resources Build Phase. Like this… (error checking
omitted)
NSString* scriptPath = [[NSBundle mainBundle] pathForResource:exformat
ofType:@"scpt"
inDirectory:nilOrWhatever] ;
NSURL* scriptUrl = [NSURL fileURLWithPath:scriptPath] ;
NSAppleScript* script = [[NSAppleScript alloc] initWithContentsOfURL:scriptUrl
error:&errorDic]
;
NSAppleEventDescriptor* descriptor = [script executeAndReturnError:&error] ;
[script release] ;
> Did somebody bump into such a thing before?
When I wanted to do this, I ended up specifying the menu items by number. It's
probably more fragile than keyboard shortcuts, but System Events are pretty
fragile anyhow. The AppleScript workflow is to keep trying different things
that should work until you find one that does work.
Here is part of the script which I use:
tell application "System Events"
set oldClipboard to the clipboard
set the clipboard to ""
tell process "Whatever"
set frontmost to true
set editCopyMenuItem to a reference to menu item 5 of menu of menu bar
item 4 of menu bar 1
set isEnabled to enabled of editCopyMenuItem as boolean
if (isEnabled is true) then
click editCopyMenuItem
end if
end tell
delay 0.1
copy (the clipboard) to selectedText
set the clipboard to oldClipboard
end tell
-- Make sure that none of your property keys are AppleScript reserved words,
nor used in the target app's terminology, or the following will give unexpected
results…
return {whatever:whatever textIWant:selectedText, whateverElse:whateverElse}
Comment regarding the delay 0.1:
-- Sometimes, copy (the clipboard) gets previous clipboard data unless we use a
delay. The more, the better. We chose 0.1 as a good compromise. Even without
this delay, this script takes 0.2 seconds to execute anyhow.
Regarding your code for processing the script output, it looks different than
mine. I use -[NSAppleEventDescriptor stringValue]. This works for me:
NSMutableDictionary* infoFromScript = [[NSMutableDictionary alloc] init] ;
NSInteger i ;
for (i=1; i<=[descriptor numberOfItems]; i++) {
// This loop should only execute once; [descriptor numberOfItems] = 1
NSAppleEventDescriptor* subdescriptor = [descriptor descriptorAtIndex:i] ;
NSInteger nItems = [subdescriptor numberOfItems] ;
if ((nItems > 0) && (nItems%2 == 0)) {
NSUInteger j ;
for(j=1; j<=[subdescriptor numberOfItems]/2; j++) {
NSString* key = [[subdescriptor descriptorAtIndex:(2*j-1)]
stringValue] ;
NSString* value = [[subdescriptor descriptorAtIndex:(2*j)]
stringValue] ;
if (key && value) {
[infoFromScript setObject:value
forKey:key] ;
}
}
break ;
}
}

Well, some would say that AppleScript is kind of a known problem :))

Re: any way to know where a UIBarButtonItem has been drawn?
If your use case permits, you can figure out the frame of the bar button item
in it's action selector by giving the selector the following signature:
- (void)barButtonAction:(UIBarButtonItem *)item event:(UIEvent *)event;
You can then use the properties of UIEvent to get the touches location, or the
view that the touches belong to.
For instance:
- (IBAction)barButtonAction:(UIBarButtonItem *)sender event:(UIEvent *)event{
UITouch *touch = [[event allTouches] anyObject];
CGPoint locationInView = [[[event allTouches] anyObject]
locationInView:self.view];
NSLog(@"event touch location = %@", [NSValue
valueWithCGPoint:locationInView]);
NSLog(@"touch.view = %@", [touch view]);
}

web view moving in split view when keyboard comes up
I have a UIWebView loading a Sencha Touch html page in a split view. The autosizing for the web view is set to the left and top in Interface Builder with the four in the middle, right, and bottom disabled, although I've tried many combinations. The issue occurs when you touch in the sencha dialog box and the keyboard comes up. The web view itself moves up. In another case it moves up and left. Is it my autosizing that is wrong or web code? code: http://ragehip.com/split.zip Thanks!

Yes, I tried, It didn't make things work more consistent :(

I have a scpt file, that does it and tried use it also. The script activates
the frontmost application

0.1 makes you wait reasonable amount of time. And as I use it twice or more,
you come to some 0.5 delay which is already something that feels a bit slow.

I found that it brings the unicode characters. I'll try string value.

I have another question.
My application intercepts clicks/key down events and brings the text from the
frontmost application to my application on catching a certain key sequence.
Then it evaluates it and pastes fixed text back to the application, that was
frontmost.
I tried using accessibility APIs, but not all applications support it.
AppleScript seems to be the universal solution in this case, since it's mostly
simulates copy & paste key sequences, but may be there are another
technologies, that can be used for this purpose. Are you aware of something
more robust?
Thanks,

strange values for boundingRectForGlyphRange with SE-Asian fonts
I get the bounding rect for all glyphs in my TextView subclass and display them.
Looks perfect: the boxes snugly fit the characters.
But when a line contains any Thai character (similar for Laos, Burma, Khmer)
then the boxes are strangly wide.
Why? Is there some good reason for this? Or am I doing something wrong?
Example: font = Thonburi 48pt. One line of "Wim" prints:
2011-09-13 12:01:36.072 NSFontAttributeExplorer[5156:707] -[FontView
setFont:andString:] 3 glyps - self {{0, 0}, {205, 231}}
2011-09-13 12:01:36.075 NSFontAttributeExplorer[5156:707] -[FontView
setFont:andString:] textContainer {205, 1000}
2011-09-13 12:01:36.075 NSFontAttributeExplorer[5156:707] -[FontView
setFont:andString:] glyphs[0] = 172 rect {{5, 0},
{45.453, 66}}
2011-09-13 12:01:36.077 NSFontAttributeExplorer[5156:707] -[FontView
setFont:andString:] glyphs[1] = 190 rect {{50.453, 0},
{11.2687497, 66}}
2011-09-13 12:01:36.077 NSFontAttributeExplorer[5156:707] -[FontView
setFont:andString:] glyphs[2] = 194 rect {{61.71875, 0},
{42.918746948242188, 66}}
but the line "Wimม" (last char is Thai character mo ma = U+0E21) prints:
2011-09-13 12:03:55.684 NSFontAttributeExplorer[5156:707] -[FontView
setFont:andString:] 4 glyps - self {{0, 0}, {205, 231}}
