• How do you keep text from wrapping in an NSTableView using NSAttributedString

  - by Justin

  I have an NSTableView that has 2 columns, one for an icon and the other for two lines of text. In the second column, the text column, I have some larger text that is for the name of an item. Then I have a new line and some smaller text that describes the state of the item. When the name becomes so large that it doesn't fit on one line it wraps (or when you shrink the window down so small that it causes the names to not fit on a single line). row1=============== | image |  some name   | | image |   idle               | row2================ | image |  some name really long name   | <- this gets wrapped pushing 'idle' out of the view | image |   idle               | =================== My question is, how could I keep the text from wrapping and just have the NSTableView display a horizontal scroll-bar once the name is too large to fit?

• Focus Window by CGWindowID

  - by JustSid

  Is it possible to focus a NSWindow by its CGWindowID? And yes, how? I need to focus a Window of another application, but I have only its CGWindowID and I can only find sample code about retrieving the ID, but not how to focus a Window by its ID.

• How can I move the clear button in a UITextField?

  - by Jake

  For some reason, when I add a UITextfield as a subview of the contentview of a tablecell, the clearbutton does not align with the text typed in the field, and appears a bit underneath it. Is there any way I can move the text of the clearbutton to stop this from happening? Thanks for any help,

• Unicode data from NSData to NSString

  - by Jeff

  So if I have NSData from an HTTP request, then I do something like this: NSString *test = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; This will result in null if the data contains weird unicode data (title is from reddit): {"title":"click..¦¦me..and..then¦¦________ ¦¦check¦¦_.your...¦¦.__...¦¦____ ¦¦....¦¦¦¦¦¦¦¦¦¦¦¦¦¦....¦¦____ ¦¦¦¦¦¦....¦¦¦¦¦¦....¦¦¦¦¦¦____ ¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦____ ....¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦______ ........¦¦..._recently....¦¦________ ....¦¦....viewed....links....¦¦_____"}, How would I convert the data to a string? Ideally, it would best if the string wasn't null so I could parse it as JSON, but even a lossy conversion is fine with me in these cases. I'm not familiar with unicode (naive American I am), so any enlightenment about that would be a nice bonus :)

• Cannot figure out how to get rid of memory leak

  - by Mark S.

  I'm trying to test for memory leaks in my iphone and I'm not having much luck getting rid of this one. Here is the code that is leaking. - (id)initWithManagedObjectContext:(NSManagedObjectContext *)aMoc delegate:(id)aDelegate runSync:(BOOL)aRunSync { if (self = [super init]) { self.moc = aMoc; self.settingsManager = [[VacaCalcSettingsManager alloc] initWithManagedObjectContext:self.moc]; self.delegate = aDelegate; calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar]; self.runSync = aRunSync; } return self; } It is leaking on the self.settingsManager = [[VacaCalcSettingsManager alloc] initWithManagedObjectContext:self.moc]; line. The self.settingManager instance variable is released in the dealloc method of the class. I'm not sure what other information would be pertinent. Please let me know and I can provide it. Thanks for any assistance. -Mark

• No Debug information of an iPhone app

  - by Markus Pilman

  Hi all, I wrote an iPhone app which uses a third party library. I crosscompiled this library successfully and everything works smoothly. But when I want to debug the application, it would make sense to also be able to debug the library. So I compiled also the external library with debuging information (usign the gcc option -ggdb). But when I want to debug it, I get the correct symbol names, but the positions are always wrong/extremly wierd (locale_facets.tcc:2505 or iostream:76). For example a stack trace could look like this: #0 0x000045e8 in zorba::serialization::SerializeBaseClass::SerializeBaseClass () at iostream:76 #1 0x0001d990 in zorba::RCObject::RCObject () at iostream:76 #2 0x00025187 in zorba::xqpStringStore::xqpStringStore () at iostream:76 #3 0x000719e4 in zorba::String::String () at locale_facets.tcc:2505 #4 0x00030513 in iphone::iLabelModule::getURI (this=0x533f710) at /Users/sausalito/eth/izorba/sandbox/ilabel.cpp:19 #5 0x00356766 in zorba::static_context::bind_external_module () at locale_facets.tcc:2505 #6 0x0006139d in zorba::StaticContextImpl::registerModule () at locale_facets.tcc:2505 #7 0x000333e5 in -[ZorbaCaller init] (self=0x53405c0, _cmd=0x95583398) at /Users/sausalito/eth/izorba/sandbox/ZorbaCaller.mm:61 #8 0x00033180 in +[ZorbaCaller instance] (self=0x11dc2bc, _cmd=0x93679591) at /Users/sausalito/eth/izorba/sandbox/ZorbaCaller.mm:37 #9 0x0003d998 in -[testOne execute:] (self=0x530d560, _cmd=0x9366b126, sender=0x5121da0) at /Users/sausalito/eth/izorba/sandbox/generator/testOne.mm:13 #10 0x01a21405 in -[UIApplication sendAction:to:from:forEvent:] () #11 0x01a84b4e in -[UIControl sendAction:to:forEvent:] () #12 0x01a86d6f in -[UIControl(Internal) _sendActionsForEvents:withEvent:] () #13 0x01a85abb in -[UIControl touchesEnded:withEvent:] () #14 0x01a3addf in -[UIWindow _sendTouchesForEvent:] () #15 0x01a247c8 in -[UIApplication sendEvent:] () #16 0x01a2b061 in _UIApplicationHandleEvent () #17 0x03b6fd59 in PurpleEventCallback () #18 0x034a8b80 in CFRunLoopRunSpecific () #19 0x034a7c48 in CFRunLoopRunInMode () #20 0x03b6e615 in GSEventRunModal () #21 0x03b6e6da in GSEventRun () #22 0x01a2bfaf in UIApplicationMain () #23 0x0002dd7e in main (argc=1, argv=0xbffff044) at /Users/sausalito/eth/izorba/sandbox/main.m:16 Does anybody have an idea, where these wrong locations come from?

• Unit Testing Model Classes that derive from NSManagedObject

  - by Matt Baker

  So...I'm trying to get unit tests set up in my iPhone App but I'm having some issues. I'm trying to test my model classes but they inherit directly from NSManagedObject. I'm sure this is a problem but I don't know how to get around it. Everything is building and running as expected but I get this error when calling any method on the class I'm testing: Unknown.m:0:0 unrecognized selector sent to instance 0xc2b120 If I follow this structure (http://chanson.livejournal.com/115621.html) to create my object in my tests I end up with another error entirely but it still doesn't help me. Basically my question is this: how can I test a class that inherits from NSManagedObject?

• Cocoa NSWindow not updating with data

  - by Matt S.

  I have an NSWindow that shows up when you click either of two items (both from an NSTableView). I have a setter method that tells the window what information to display. This all works perfectly, until it comes time to display the data in the window. If I cause the window to display from one tableview, then try to have it display the new data from another it doesn't do it, it keeps the old data on. I am using the exact same method to get and display the data from both possible ways to have the window show up, and the data is changing correctly. To display the window I'm using [mywindow makeKeyAndOrderFront:self];

• ParseKit.framework won't work, Foundation.h not found

  - by Jeremy

  I'm really stumped trying to get the ParseKit.framework (this) to work in general, not even bothering to implement it till it runs the demo app that comes with it. What happens is the compiler can't locate < Foundation/Foundation.h or something, which I thought the header was in the linked framework. Exact error: "Lexical or Preprocessor Issue: 'Foundation/Foundation.h' file not found." Here's the code, just from the ParseKit_Prefix.pch: // // Prefix header for all source files of the 'ParseKit' target in the 'ParseKit' project. //#ifdef __OBJC__ #import <Foundation/Foundation.h> #endif Nothing unusual about it, did I mess up the file paths some how? I've reinstalled Xcode, re-downloaded the ParseKit, and nothing is helping. The suggestions here did nothing and it's not this. When I make a new project or use a different project and load the Foundation.framework and #import the header it works just fine. If I unlink the framework I can't find it to re-link again. Has anyone else had this kind of problem? Did I download it wrong somewhere? I have a very difficult time finding where exactly the Xcode UI links stuff, apple must get a kick out of frustrating people, so if anyone has anything they can think of please give me some feedback, I'm horribly confused right now. Thanks,

• CoreData: Same predicate (IN) returns different fetched results after a Save operation

  - by Jason Lee

  I have code below: NSArray *existedTasks = [[TaskBizDB sharedInstance] fetchTasksWatchedByMeOfProject:projectId]; [context save:&error]; existedTasks = [[TaskBizDB sharedInstance] fetchTasksWatchedByMeOfProject:projectId]; NSArray *allTasks = [[TaskBizDB sharedInstance] fetchTasksOfProject:projectId]; First line returns two objects; Second line save the context; Third line returns just one object, which is contained in the 'two objects' above; And the last line returns 6 objects, containing the 'two objects' returned at the first line. The fetch interface works like below: WXModel *model = [WXModel modelWithEntity:NSStringFromClass([WQPKTeamTask class])]; NSPredicate *predicate = [NSPredicate predicateWithFormat:@"(%@ IN personWatchers) AND (projectId == %d)", currentLoginUser, projectId]; [model setPredicate:predicate]; NSArray *fetchedTasks = [model fetch]; if (fetchedTasks.count == 0) return nil; return fetchedTasks; What confused me is that, with the same fetch request, why return different results just after a save? Here comes more detail: The 'two objects' returned at the first line are: <WQPKTeamTask: 0x1b92fcc0> (entity: WQPKTeamTask; id: 0x1b9300f0 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WQPKTeamTask/p9> ; data: { projectId = 372004; taskId = 338001; personWatchers = ( "0xf0bf440 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WWPerson/p1>" ); } <WQPKTeamTask: 0xf3f6130> (entity: WQPKTeamTask; id: 0xf3cb8d0 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WQPKTeamTask/p11> ; data: { projectId = 372004; taskId = 340006; personWatchers = ( "0xf0bf440 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WWPerson/p1>" ); } And the only one object returned at third line is: <WQPKTeamTask: 0x1b92fcc0> (entity: WQPKTeamTask; id: 0x1b9300f0 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WQPKTeamTask/p9> ; data: { projectId = 372004; taskId = 338001; personWatchers = ( "0xf0bf440 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WWPerson/p1>" ); } Printing description of allTasks: <_PFArray 0xf30b9a0>( <WQPKTeamTask: 0xf3ab9d0> (entity: WQPKTeamTask; id: 0xf3cda40 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WQPKTeamTask/p6> ; data: <fault>), <WQPKTeamTask: 0xf315720> (entity: WQPKTeamTask; id: 0xf3c23a0 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WQPKTeamTask/p7> ; data: <fault>), <WQPKTeamTask: 0xf3a1ed0> (entity: WQPKTeamTask; id: 0xf3cda30 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WQPKTeamTask/p8> ; data: <fault>), <WQPKTeamTask: 0x1b92fcc0> (entity: WQPKTeamTask; id: 0x1b9300f0 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WQPKTeamTask/p9> ; data: { projectId = 372004; taskId = 338001; personWatchers = ( "0xf0bf440 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WWPerson/p1>" ); }), <WQPKTeamTask: 0xf325e50> (entity: WQPKTeamTask; id: 0xf343820 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WQPKTeamTask/p10> ; data: <fault>), <WQPKTeamTask: 0xf3f6130> (entity: WQPKTeamTask; id: 0xf3cb8d0 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WQPKTeamTask/p11> ; data: { projectId = 372004; taskId = 340006; personWatchers = ( "0xf0bf440 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WWPerson/p1>" ); }) ) UPDATE 1 If I call the same interface fetchTasksWatchedByMeOfProject: in: #pragma mark - NSFetchedResultsController Delegate - (void)controllerDidChangeContent:(NSFetchedResultsController *)controller { I will get 'two objects' as well. UPDATE 2 I've tried: NSPredicate *predicate = [NSPredicate predicateWithFormat:@"(ANY personWatchers == %@) AND (projectId == %d)", currentLoginUser, projectId]; NSPredicate *predicate = [NSPredicate predicateWithFormat:@"(ANY personWatchers.personId == %@) AND (projectId == %d)", currentLoginUserId, projectId]; Still the same result.

• Defined outlets, connected them, everything looks fine, nothing works.

  - by Tom

  Hi! I'm trying to play with a WebView. I made an outlet: IBOutlet UIWebView *browser; Defined it as a property: @property (nonatomic, retain) IBOutlet UIWebView *browser; Synthethized it: @synthesize browser; Finally, I connected it in Interface Builder, really it is. Then I try to do something with it i.e.: [browser loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://apple.com"]]]; Or also: Etape *etape = [[Etape alloc] init]; NSString *html = [etape generateHTMLforEtape:[current_etape objectAtIndex:0]]; [browser loadHTMLString:html baseURL:nil]; [etape release]; I get no errors, I tried to Build & Analyse, no notices or warnings or errors.. I've been searching for one whole day, please help me :/ Thanks a lot! EDIT: Here's screenshots of my connections for my WebView:

• iphone integer multiplication

• Copy NSArray and replace text items with bool values

  - by Frank Martin

  I utilize a (nested) plist to populate UITableViews where users can select entries at the deepest levels and set a checkmark (or not). I want to save these selections in a same structured list where at the deepest level the NSArray contains bool values instead the text strings that are displayed in the UITableView. So how can i build from a hierarchy like the following: Root - Item 0 (Dictionary) - Group (Dictionary) - Items (NSArray) - Item 0: @"Please check me" (String) a hierarchy like this? Root - Item 0 (Dictionary) - Group (Dictionary) - Items (NSArray) - Item 0: 0 (NSNumber) // NSNumber for bool values I'm trying to create a deep mutable copy and replace the items at the deepest levels but have somehow the feeling that this can be done easier. Thanks for any help with this in advance. Frank

• iPhone not returning to application after calling eMail send

  - by Bill

  I am sending an email from within my iPhone application. The eMail page pops up ok, I click on the Send button, the iPhone plays a whoosh sound, and the eMail actually arrives at the recipient. Unfortunately, the mail dialog still sits there unresponsive, and the only option - to click the home button - kills the app. Is there something else that needs to be specified to close the eMailMessage view? MFMailComposeViewController *eMailMessage; NSArray *toAddress; if ([MFMailComposeViewController canSendMail]) { toAddress = [NSArray arrayWithObject:@"[email protected]"]; eMailMessage = [[MFMailComposeViewController alloc] init]; [eMailMessage setToRecipients:toAddress]; [eMailMessage setSubject:@"Notification"]; [eMailMessage setMessageBody:@"Performed by ..." isHTML:NO]; [self presentModalViewController:eMailMessage animated:YES]; [eMailMessage release]; }

• OpenGL ES functions not accepting values originating outside of it's view

  - by Josh Elsasser

  I've been unable to figure this out on my own. I currently have an Open GLES setup where a view controller both updates a game world (with a dt), fetches the data I need to render, passes it off to an EAGLView through two structures (built of Apple's ES1Renderer), and draws the scene. Whenever a value originates outside of the Open GL view, it can't be used to either translate objects using glTranslatef, or set up the scene using glOrthof. If I assign a new value to something, it will work - even if it is the exact same number. The two structures I have each contain a variety of floating-point numbers and booleans, along with two arrays. I can log the values from within my renderer - they make it there - but I receive errors from OpenGL if I try to do anything with them. No crashes result, but the glOrthof call doesn't work if I don't set the camera values to anything different. Code used to set up scene: [EAGLContext setCurrentContext:context]; glBindFramebufferOES(GL_FRAMEBUFFER_OES, viewFramebuffer); //clears the color buffer bit glClear(GL_COLOR_BUFFER_BIT); glMatrixMode(GL_PROJECTION); //sets up the scene w/ ortho projection glViewport(0, 0, 320, 480); glLoadIdentity(); glOrthof(320, 0, dynamicData.cam_x2, dynamicData.cam_x1, 1.0, -1.0); glClearColor(1.0, 1.0, 1.0, 1.0); /*error checking code here*/ "dynamicData" (which is replaced every frame) is created within my game simulation. From within my controller, I call a method (w/in my simulation) that returns it, and pass the result on to the EAGLView, which passes it on to the renderer. I haven't been able to come up with a better solution for this - suggestions in this regard would be greatly appreciated as well. Also, this function doesn't work as well (values originate in the same place): glTranslatef(dynamicData.ship_x, dynamicData.ship_y, 0.0); Thanks in advance. Additional Definitions: Structure (declared in a separate header): typedef struct { float ship_x, ship_y; float cam_x1, cam_x2; } dynamicRenderData; Render data getter (and builder) (every frame) - (dynamicData)getDynRenderData { //d_rd is an ivar, zeroed on initialization d_rd.ship_x = mainShip.position.x; d_rd.ship_y = mainShip.position.y; d_rd.cam_x1 = d_rd.ship_x - 30.0f; d_rd.cam_x2 = d_rd.cam_x1 + 480.0f; return d_rd; } Zeroed at start. (d_rd.ship_x = 0;, etc…) Setting up the view. Prototype (GLView): - (void)draw: (dynamicRenderData)dynamicData Prototype (Renderer): - (void)drawView: (dynamicRenderData)dynamicData How it's called w/in the controller: //controller [glview draw: [world getDynRenderData]]; //glview (within draw) [renderer drawView: dynamicData];

If I search for "test," I get 0 results. But if I search for "test one" or "test two" I get the proper result. The search is ignoring the space. In reality I want both results if the user searches for "test." Any ideas? I tried contain and like.

• Generating a Grid of NSTextField Objects From NSDictionary Items

  - by SteveStifler

  I'm trying to create an vocabulary study application using Obj-C and the Cocoa frameworks. I have about two week's experience in both areas and have reached an edge of my current knowledge. Here's where I'm stuck. When I press a checkbox, a corresponding plist is loaded into memory as an NSDictionary. I want to generate a "Label: Textfield" pair for each key:value pair, where the Label is the key. When the text typed into the Textfield matches the key's value, I want the Label's text to turn green. So how would I generate this grid, and once generated, how would I make the text green upon correct input? Thanks!

• Getting text position while parsing pdf with Quartz 2D

  Hi guys, another question regarding pdf parsing... Just read PDF Reference version 1.7 "5.3.1 Text-Positioning Operators" and I am a little bit confused. I wrote some code to get transformation matrix and initial text position. CGPDFOperatorTableSetCallback (table, "MP", &op_MP);//Define marked-content point CGPDFOperatorTableSetCallback (table, "DP", &op_DP);//Define marked-content point with property list CGPDFOperatorTableSetCallback (table, "BMC", &op_BMC);//Begin marked-content sequence CGPDFOperatorTableSetCallback (table, "BDC", &op_BDC);//Begin marked-content sequence with property list CGPDFOperatorTableSetCallback (table, "EMC", &op_EMC);//End marked-content sequence //Text State operators CGPDFOperatorTableSetCallback(table, "Tc", &op_Tc); CGPDFOperatorTableSetCallback(table, "Tw", &op_Tw); CGPDFOperatorTableSetCallback(table, "Tz", &op_Tz); CGPDFOperatorTableSetCallback(table, "TL", &op_TL); CGPDFOperatorTableSetCallback(table, "Tf", &op_Tf); CGPDFOperatorTableSetCallback(table, "Tr", &op_Tr); CGPDFOperatorTableSetCallback(table, "Ts", &op_Ts); //text showing operators CGPDFOperatorTableSetCallback(table, "TJ", &op_TJ); CGPDFOperatorTableSetCallback(table, "Tj", &op_Tj); CGPDFOperatorTableSetCallback(table, "'", &op_apostrof); CGPDFOperatorTableSetCallback(table, "\"", &op_double_apostrof); //text positioning operators CGPDFOperatorTableSetCallback(table, "Td", &op_Td); CGPDFOperatorTableSetCallback(table, "TD", &op_TD); CGPDFOperatorTableSetCallback(table, "Tm", &op_Tm); CGPDFOperatorTableSetCallback(table, "T*", &op_T); //text object operators CGPDFOperatorTableSetCallback(table, "BT", &op_BT);//Begin text object CGPDFOperatorTableSetCallback(table, "ET", &op_ET);//End text object So this is the output after application lunch: 2010-09-02 15:09:23.041 testSearch[8251:207] op_BT begin Integer value: 0 2010-09-02 15:09:23.043 testSearch[8251:207] op_BT end 2010-09-02 15:09:23.043 testSearch[8251:207] op_Tf begin Integer value: 1 2010-09-02 15:09:23.044 testSearch[8251:207] op_Tf end 2010-09-02 15:09:23.044 testSearch[8251:207] op_Tm begin Float value: 557.364197 2010-09-02 15:09:23.045 testSearch[8251:207] op_Tm end 2010-09-02 15:09:23.045 testSearch[8251:207] op_TJ begin 2010-09-02 15:09:23.046 testSearch[8251:207] Array string value [0]: F 2010-09-02 15:09:23.046 testSearch[8251:207] Array integer value [1]: 94985208 2010-09-02 15:09:23.047 testSearch[8251:207] Array string value [2]: r 2010-09-02 15:09:23.047 testSearch[8251:207] Array integer value [3]: 94985208 2010-09-02 15:09:23.048 testSearch[8251:207] Array string value [4]: o 2010-09-02 15:09:23.048 testSearch[8251:207] Array integer value [5]: 94985208 2010-09-02 15:09:23.049 testSearch[8251:207] Array string value [6]: m s 2010-09-02 15:09:23.049 testSearch[8251:207] Array integer value [7]: 94985208 2010-09-02 15:09:23.049 testSearch[8251:207] Array string value [8]: a 2010-09-02 15:09:23.050 testSearch[8251:207] Array integer value [9]: 94985208 2010-09-02 15:09:23.050 testSearch[8251:207] Array string value [10]: m 2010-09-02 15:09:23.051 testSearch[8251:207] Array integer value [11]: 94985208 2010-09-02 15:09:23.051 testSearch[8251:207] Array string value [12]: p 2010-09-02 15:09:23.052 testSearch[8251:207] Array integer value [13]: 94985208 2010-09-02 15:09:23.053 testSearch[8251:207] Array string value [14]: l 2010-09-02 15:09:23.054 testSearch[8251:207] Array integer value [15]: 94985208 2010-09-02 15:09:23.055 testSearch[8251:207] Array string value [16]: e t 2010-09-02 15:09:23.055 testSearch[8251:207] Array integer value [17]: 94985208 2010-09-02 15:09:23.057 testSearch[8251:207] Array string value [18]: o r 2010-09-02 15:09:23.057 testSearch[8251:207] Array integer value [19]: 94985208 2010-09-02 15:09:23.058 testSearch[8251:207] Array string value [20]: e 2010-09-02 15:09:23.058 testSearch[8251:207] Array integer value [21]: 94985208 2010-09-02 15:09:23.059 testSearch[8251:207] Array string value [22]: s 2010-09-02 15:09:23.059 testSearch[8251:207] Array integer value [23]: 94985208 2010-09-02 15:09:23.060 testSearch[8251:207] Array string value [24]: u 2010-09-02 15:09:23.061 testSearch[8251:207] Array integer value [25]: 94985208 2010-09-02 15:09:23.061 testSearch[8251:207] Array string value [26]: l 2010-09-02 15:09:23.062 testSearch[8251:207] Array integer value [27]: 94985208 2010-09-02 15:09:23.062 testSearch[8251:207] Array string value [28]: t 2010-09-02 15:09:23.063 testSearch[8251:207] op_TJ end If someone is familiar with text matrix and text positioning operators it would be nice to explain how all those thing work. How to calculate text position (or glyph?) using Tm (transformation matrix and other data)?
