  • Strange \n in base64 encoded string in Ruby

    - by intellidiot
    The inbuilt Base64 library in Ruby is adding some '\n's. I'm unable to find out the reason. For this special example: irb(main):001:0> require 'rubygems' => true irb(main):002:0> require 'base64' => true irb(main):003:0> str = "1110--ad6ca0b06e1fbeb7e6518a0418a73a6e04a67054" => "1110--ad6ca0b06e1fbeb7e6518a0418a73a6e04a67054" irb(main):004:0> Base64.encode64(str) => "MTExMC0tYWQ2Y2EwYjA2ZTFmYmViN2U2NTE4YTA0MThhNzNhNmUwNGE2NzA1\nNA==\n" The \n's are at the last and 6th position from end. The decoder (Base64.decode64) returns back the old string perfectly. Strange thing is, these \n's don't add any value to the encoded string. When I remove the newlines from the output string, the decoder decodes it again perfectly. irb(main):005:0> Base64.decode64(Base64.encode64(str).gsub("\n", '')) == str => true More of this, I used an another JS library to produce the base64 encoded output of the same input string, the output comes without the \n's. Is this a bug or anything else? Has anybody faced this issue before? FYI, $ ruby -v ruby 1.8.7 (2008-08-11 patchlevel 72) [i486-linux]

  • Placemark not giving city name in ios 6

    - by Sawant
    I am using this code in which i am getting Placemark but it not giving the city name. Earlier i am using MKReverse Geocoder to get the placemark in which i am getting the city name but as in ios6 it showing deprecated because the apple developer added every thing in CLLocation. so i used this code. `-(void) locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation { CLLocation *location = [locationManager location]; NSLog(@"location is %@",location); CLGeocoder *fgeo = [[[CLGeocoder alloc] init] autorelease]; // Reverse Geocode a CLLocation to a CLPlacemark [fgeo reverseGeocodeLocation:location completionHandler:^(NSArray *placemarks, NSError *error){ // Make sure the geocoder did not produce an error // before continuing if(!error){ // Iterate through all of the placemarks returned // and output them to the console for(CLPlacemark *placemark in placemarks){ NSLog(@"%@",[placemark description]); city1= [placemark.addressDictionary objectForKey:(NSString*) kABPersonAddressCityKey]; NSLog(@"city is %@",city1); } } else{ // Our geocoder had an error, output a message // to the console NSLog(@"There was a reverse geocoding error\n%@", [error localizedDescription]); } } ]; } ` here as i am seeing in console in NSLog(@"%@",[placemark description]); its giving output like :- abc road name,abc road name, state name,country name. any help please .Thanking in advance.

  • php resize image

    - by haohan
    I have a class to read and output the image content, if $width is set, it will resize the image, and then output it. If I call the function like this $image-readImage('123.jpg'); , it can output the image file correctly, but when I call $image-readImage('123.jpg'); , it just display a black image with resized width & height. And I tried to replace the code from @imagejpeg($thumb, null, 100); to @imagejpeg($image, null, 100); will works~ - protected function readImage($fileName, $width = 0) { if ($width <= 0) { return @file_get_contents($this-destination . '/' . $fileName); } else { $imageSize = @getimagesize($this-destination . '/' . $fileName); $actualWidth = $imageSize[0]; $actualHeigth = $imageSize[1]; if ($actualWidth <= $width) { return @file_get_contents($this-destination . '/' . $fileName); } $height = (100 / ($actualWidth / $width)) * .01; $height = @round($actualHeigth * $height); $image = @imagecreatefromjpeg($this-destination . '/' . $fileName); $thumb = @imagecreatetruecolor($width, $height); @imagecopyresampled($thumb, $image, 0, 0, 0, 0, $width, $height, $actualWidth, $actualHeight); ob_start(); @imagejpeg($thumb, null, 100); $bits = ob_get_contents(); ob_end_clean(); return $bits; } } Any experts know what happened and help me to solve it ? Thanks.

  • Function that prints something to std::ostream and returns std::ostream?

    - by dehmann
    I want to write a function that outputs something to a ostream that's passed in, and return the stream, like this: std::ostream& MyPrint(int val, std::ostream* out) { *out << val; return *out; } int main(int argc, char** argv){ std::cout << "Value: " << MyPrint(12, &std::cout) << std::endl; return 0; } It would be convenient to print the value like this and embed the function call in the output operator chain, like I did in main(). It doesn't work, however, and prints this: $ ./a.out 12Value: 0x6013a8 The desired output would be this: Value: 12 How can I fix this? Do I have to define an operator<< instead? UPDATE: Clarified what the desired output would be. UPDATE2: Some people didn't understand why I would print a number like that, using a function instead of printing it directly. This is a simplified example, and in reality the function prints a complex object rather than an int.

  • Loop with a while

    - by ookla
    Very basic question.. but I'm missing the point.. I have this data on my table: ID SITEID SECTION 1 1 posts 2 2 posts 3 1 aboutme 4 1 contact 5 2 questions The output is an array. I can't change it. I want to make this output on php with a single for loop with that array: <h1> sections for site 1 </h1> posts aboutme contact <h1>sections for site 2 </h1> posts questions I'm trying to do something like this, where $sectionsArray is my output. And I want to check if siteid is the same, then make a loop.. for ($j=0;$j<sizeof($sectionsArray);$j++) { while (siteid==1){ echo "<h1>'.$sectionsArray['siteid'].'</h1>'; } echo "<A href='section.php?id='.$sectionsArray['id'].' '">'.$sectionsArray['section'].'</a>; } But I don't get the logic of "grouping" the results with a while.. INSIDE a loop. Any light will be welcome. Thanks

  • Encoding h.264 with libavcodec/x264

    - by Leviathan
    I am attempting to encode video using libavcodec/libavformat. I'm trying to change the standard output-example.c from ffmpeg source. The AVI file is created on the disk, but the only sound is encoded. I tried adding a lot of options for x264 from here. All the other codecs works fine, mpeg2, mpeg4, mjpeg, xvid. In addition to specifying the parameters x264, I also set the codec to AVOutputFormat structure. That's all I've done. AVOutputFormat *pOutFormat; // in header file av_register_all(); AVCodec *codec = avcodec_find_encoder_by_name("libx264"); pOutFormat = guess_format("avi", NULL, NULL); pOutFormat->video_codec = codec->id; The debug output of my application: Output #0, mp4, to 'D:\1.avi': Stream #0.0: Video: libx264, yuv420p, 320x240, q=10-51, 500 kb/s, 90k tbn, 25 tbc Stream #0.1: Audio: aac, 44100 Hz, 1 channels, s16, 128 kb/s [libx264 @ 0x694010]using cpu capabilities: MMX2 SSE2Fast SSSE3 FastShuffle SSE4.2 [libx264 @ 0x694010]bitrate tolerance too small, using .01 [libx264 @ 0x694010]profile Main, level 2.0 [libx264 @ 0x694010]frame I:150 Avg QP:14.76 size: 2534 [libx264 @ 0x694010]mb I I16..4: 75.9% 0.0% 24.1% [libx264 @ 0x694010]final ratefactor: 17.57 [libx264 @ 0x694010]coded y,uvDC,uvAC intra: 42.7% 92.4% 47.4% [libx264 @ 0x694010]i16 v,h,dc,p: 11% 14% 2% 73% [libx264 @ 0x694010]i4 v,h,dc,ddl,ddr,vr,hd,vl,hu: 21% 18% 29% 5% 8% 10% 3% 3% 2% [libx264 @ 0x694010]kb/s:506.79

  • Issue using GAE appcfg.py

    - by JustSmith
    I get nothing out of appcfg.py besides the default output. I'm trying to upload some data to my development project with no luck at at all. From the instructions on the Google App Engine page the steps are as follows: Edit app.yaml update with appcfg.py make upload script upload with appcfg.py After step one I try to run the update and it never shows any success. The following commands product the same output: appcfg.py appcfg.py update appDir appcfg.py update appDir/ appcfg.py update /appDir If i try to follow the instructions from the appcfg.py output and type help upload and get: "help <action>" I get a response from the system, This command is not supported by the help utility. Try "update /?". cause I'm calling the system help command. If I use the command appcfg.py help upload I get the same result as just typing appcfg.py Can someone show me examples of the syntax to update the dev site, upload data to it and get appcfg.py to actually give help on its commands? Also I'm just assuming that the upload script and the .csv file that are being uploaded are in they myApp directory. Appreciate any help,

  • Strange behavior using getchar() and -O3

  • Matching Regular Expression in Javascript and PHP problem...

    - by Frankie
    I can't figure out how to get the same result from my Javscript as I do from my PHP. In particular, Javascript always leaves out the backslashes.

  • Code Golf: Shortest Turing-complete interpreter.

    - by ilya n.
    I've just tried to create the smallest possible language interpreter. Would you like to join and try? Rules of the game: You should specify a programming language you're interpreting. If it's a language you invented, it should come with a list of commands in the comments. Your code should start with example program and data assigned to your code and data variables. Your code should end with output of your result. It's preferable that there are debug statements at every intermediate step. Your code should be runnable as written. You can assume that data are 0 and 1s (int, string or boolean, your choice) and output is a single bit. The language should be Turing-complete in the sense that for any algorithm written on a standard model, such as Turing machine, Markov chains, or similar of your choice, it's reasonably obvious (or explained) how to write a program that after being executred by your interpreter performs the algorithm. The length of the code is defined as the length of the code after removal of input part, output part, debug statements and non-necessary whitespaces. Please add the resulting code and its length to the post. You can't use functions that make compiler execute code for you, such as eval(), exec() or similar.

  • Threads, Sockets, and Designing Low-Latency, High Concurrency Servers

    - by lazyconfabulator
    I've been thinking a lot lately about low-latency, high concurrency servers. Specifically, http servers. http servers (fast ones, anyway) can serve thousands of users simultaneously, with very little latency. So how do they do it? As near as I can tell, they all use events. Cherokee and Lighttpd use libevent. Nginx uses it's own event library performing much the same function of libevent, that is, picking a platform optimal strategy for polling events (like kqueue on *bsd, epoll on linux, /dev/poll on Solaris, etc). They all also seem to employ a strategy of multiprocess or multithread once the connection is made - using worker threads to handle the more cpu intensive tasks while another thread continues to listen and handle connections (via events). This is the extent of my understanding and ability to grok the thousand line sources of these applications. What I really want are finer details about how this all works. In examples of using events I've seen (and written) the events are handling both input and output. To this end, do the workers employ some sort of input/output queue to the event handling thread? Or are these worker threads handling their own input and output? I imagine a fixed amount of worker threads are spawned, and connections are lined up and served on demand, but how does the event thread feed these connections to the workers? I've read about FIFO queues and circular buffers, but I've yet to see any implementations to work from. Are there any? Do any use compare-and-swap instructions to avoid locking or is locking less detrimental to event polling than I think? Or have I misread the design entirely? Ultimately, I'd like to take enough away to improve some of my own event-driven network services. Bonus points to anyone providing solid implementation details (especially for stuff like low-latency queues) in C, as that's the language my network services are written in.

  • Writing language converter in ANTLR

    - by Stefan
    I'm writing a converter between some dialects of the same programming language. I've found a grammar on the net - it's complex and handles all the cases. Now I'm trying to write the appropriate actions. Most of the input is just going to be rewritten to output. What I need to do is parse function calls, do my magic (rename function, reorder arguments, etc) and write it. I'm using AST as output. When I come across a function call, I build a custom object structure (from classes defined in my target language), call the appropriate function and I have a string that represents the transformed function that I want to get. The problem is, what I'm supposed to do with that string? I'd like to replace the .text attribute of the enclosing rule, but setText() is only available on lexer rules and the rule's .text attribute is read-only. How to solve this problem? program : statement_list { output = $statement_list.text; } ; //... statement : expression_statement // ... ; expression_statement : function_call // ... ; function_call : ID '(' { /* build the object, assign name */ Function function = new Function(); //... } ( arg1 = expression { /* add first parameter */ } ( ',' arg2 = expression { /* add the rest of parameters */ } )* )? ')' { /* convert the function call */ string converted = Tools.Convert(function); // $setText(converted); // doesn't work // $functionCall.text = converted; // doesn't work } ;

  • Getting PCM values of WAV files

  • Calling PHP functions within HEREDOC strings

    - by Doug Kavendek
    In PHP, the HEREDOC string declarations are really useful for outputting a block of html. You can have it parse in variables just by prefixing them with $, but for more complicated syntax (like $var[2][3]), you have to put your expression inside {} braces. In PHP 5, it is possible to actually make function calls within {} braces inside a HEREDOC string, but you have to go through a bit of work. The function name itself has to be stored in a variable, and you have to call it like it is a dynamically-named function. For example: $fn = 'testfunction'; function testfunction() { return 'ok'; } $string = <<< heredoc plain text and now a function: {$fn()} heredoc; As you can see, this is a bit more messy than just: $string = <<< heredoc plain text and now a function: {testfunction()} heredoc; There are other ways besides the first code example, such as breaking out of the HEREDOC to call the function, or reversing the issue and doing something like: ?> <!-- directly outputting html and only breaking into php for the function --> plain text and now a function: <?PHP print testfunction(); ?> The latter has the disadvantage that the output is directly put into the output stream (unless I'm using output buffering), which might not be what I want. So, the essence of my question is: is there a more elegant way to approach this? Edit based on responses: It certainly does seem like some kind of template engine would make my life much easier, but it would require me basically invert my usual PHP style. Not that that's a bad thing, but it explains my inertia.. I'm up for figuring out ways to make life easier though, so I'm looking into templates now.

  • Noob question about a statement in a Java program

    - by happysoul
    I am beginner to java and was trying out this code puzzle from the book head first java which I solved as follows and got the output correct :D class DrumKit { boolean topHat=true; boolean snare=true; void playSnare() { System.out.println("bang bang ba-bang"); } void playTopHat() { System.out.println("ding ding da-ding"); } } public class DrumKitTestDriver { public static void main(String[] args) { DrumKit d =new DrumKit(); if(d.snare==true) { d.playSnare(); } d.playTopHat(); } } Output is :: bang bang ba-bang ding ding da-ding Now the problem is that in that code puzzle one code snippet is left that I did not include..it's as follows d.snare=false; Even though I did not write it , I got the output like the book. I am wondering why is there need for us to set it's value as false even when we know the code is gonna run without it too !?? I am wondering what the coder had in mind ..I mean what could be the possible future use and motive behind doing this ? I am sorry if it's a dumb question. I just wanna know why or why not to include that particular statement ? It's not like there's a loop or something that we need to come out of. Why is that statement there ?

  • Problem when reading input in C

    - by gcx
    I've made a Linked List. Its elements keep both previous and next items' address. It gets commands from an input file. It detects the command and uses the following statement as a parameter. (text: add_to_front john - means: add_to_front(john)) Code: http://pastebin.com/KcAm1y3L When I try to give the commands from an input file it gives me same output over and over. However, if I write inputs in main() manually, it works. For ex input file: add_to_front john add_to_back jane add_to_back jane print (unfortunately) the output is: >add_to_front john >add_to_back jane >add_to_back jane >print jane jane jane Although, if I write add_to_front(john); add_to_back(jane); add_to_back(jane); print(); instead of this command check: while (scanf("%s",command)!=EOF) { if (strcmp(command,"add_to_front")==0) { gets(parameter); add_to_front(parameter); } else if (strcmp(command,"add_to_back")==0) { gets(parameter); add_to_back(parameter); } else if (strcmp(command,"remove_from_back")==0) remove_from_back(parameter); ... printf(" HUH?\n"); } } in main() it gives the correct output. I know it's a lot to ask but this thing is bothering me for 2 days. What do you think i'm doing wrong?

  • Render multiple control collections in ASP.NET custom control

    - by Monty
    I've build a custom WebControl, which has the following structure: <gws:ModalBox ID="ModalBox1" HeaderText="Title" runat="server"> <Contents>(controls...)</Contents> <Footer>(controls...)</Footer> </gws:ModalBox> The control contains two ControlCollection properties, 'Contents' and 'Footer'. Never tried to build a control with multiple control collections, but solved it like this (simplified): [PersistChildren(false), ParseChildren(true)] public class ModalBox : WebControl { private ControlCollection _contents; private ControlCollection _footer; public ModalBox() : base() { this._contents = base.CreateControlCollection(); this._footer = base.CreateControlCollection(); } [PersistenceMode(PersistenceMode.InnerProperty)] public ControlCollection Contents { get { return this._contents; } } [PersistenceMode(PersistenceMode.InnerProperty)] public ControlCollection Footer { get { return this._footer; } } protected override void RenderContents(HtmlTextWriter output) { // Render content controls. foreach (Control control in this.Contents) { control.RenderControl(output); } // Render footer controls. foreach (Control control in this.Footer) { control.RenderControl(output); } } } However it seems to render properly, it doesn't work anymore if I add some asp.net labels and input controls inside the property. I'll get the HttpException: Unable to find control with id 'KeywordTextBox' that is associated with the Label 'KeywordLabel'. Somewhat understandable, because the label appears before the textbox in the controlcollection. However, with default asp.net controls it does work, so why doesn't this work? What am I doing wrong? Is it even possible to have two control collections in one control? Should I render it differently? Thanks for replies.

  • Generating JavaScript in C# and subsequent testing

    We are currently developing an ASP.NET MVC application which makes heavy use of attribute-based metadata to drive the generation of JavaScript. Below is a sample of the type of methods we are writing: function string GetJavascript<T>(string javascriptPresentationFunctionName, string inputId, T model) { return @"function updateFormInputs(value){ $('#" + inputId + @"_SelectedItemState').val(value); $('#" + inputId + @"_Presentation').val(value); } function clearInputs(){ " + helper.ClearHiddenInputs<T>(model) + @" updateFormInputs(''); } function handleJson(json){ clearInputs(); " + helper.UpdateHiddenInputsWithJson<T>("json", model) + @" updateFormInputs(" + javascriptPresentationFunctionName + @"()); " + model.GetCallBackFunctionForJavascript("json") + @" }"; } This method generates some boilerplace and hands off to various other methods which return strings. The whole lot is then returned as a string and written to the output. The question(s) I have are: 1) Is there a nicer way to do this other than using large string blocks? We've considered using a StringBuilder or the Response Stream but it seems quite 'noisy'. Using string.format starts to become difficult to comprehend. 2) How would you go about unit testing this code? It seems a little amateur just doing a string comparison looking for particular output in the string. 3) What about actually testing the eventual JavaScript output? Thanks for your input!

  • t-sql most efficient row to column? crosstab for xml path, pivot

    - by ajberry
    I am looking for the most performant way to turn rows into columns. I have a requirement to output the contents of the db (not actual schema below, but concept is similar) in both fixed width and delimited formats. The below FOR XML PATH query gives me the result I want, but when dealing with anything other than small amounts of data, can take awhile. select orderid ,REPLACE(( SELECT ' ' + CAST(ProductId as varchar) FROM _details d WHERE d.OrderId = o.OrderId ORDER BY d.OrderId,d.DetailId FOR XML PATH('') ),'&#x20;','') as Products from _orders o I've looked at pivot but most of the examples I have found are aggregating information. I just want to combine the child rows and tack them onto the parent. I should also point out I don't need to deal with the column names either since the output of the child rows will either be a fixed width string or a delimited string. For example, given the following tables: OrderId CustomerId ----------- ----------- 1 1 2 2 3 3 DetailId OrderId ProductId ----------- ----------- ----------- 1 1 100 2 1 158 3 1 234 4 2 125 5 3 101 6 3 105 7 3 212 8 3 250 for an order I need to output: orderid Products ----------- ----------------------- 1 100 158 234 2 125 3 101 105 212 250 or orderid Products ----------- ----------------------- 1 100|158|234 2 125 3 101|105|212|250 Thoughts or suggestions? I am using SQL Server 2k5. Example Setup: create table _orders ( OrderId int identity(1,1) primary key nonclustered ,CustomerId int ) create table _details ( DetailId int identity(1,1) primary key nonclustered ,OrderId int ,ProductId int ) insert into _orders (CustomerId) select 1 union select 2 union select 3 insert into _details (OrderId,ProductId) select 1,100 union select 1,158 union select 1,234 union select 2,125 union select 3,105 union select 3,101 union select 3,212 union select 3,250 using FOR XML PATH: select orderid ,REPLACE(( SELECT ' ' + CAST(ProductId as varchar) FROM _details d WHERE d.OrderId = o.OrderId ORDER BY d.OrderId,d.DetailId FOR XML PATH('') ),'&#x20;','') as Products from _orders o which outputs what I want, however is very slow for large amounts of data. One of the child tables is over 2 million rows, pushing the processing time out to ~ 4 hours. orderid Products ----------- ----------------------- 1 100 158 234 2 125 3 101 105 212 250

  • Jekyll - How to approach asset processing (minification, spriting...)

    - by Gromix
    I recently switched to Jekyll and I find the conversion pipeline works really well. However I'm stuck on which approach to take when the process is many inputs to one output (ex: concatenating CSS files, creating image sprites...) I know several tools that can do it, that can be called either from the command line or in Ruby code directly. For ex: Jammit css sprites Compass sprites My current solution is a few Jekyll plugins that call these tools. However, it has the following problems: 1. SASS files should be processed, then concatenated/minified SASS-CSS is a Converter, and the concatenation is a Generator run on the output. Unfortunately generators are run first, which means the concatenation is always a step behind (I have to run the build twice) 2. Jekyll does not know about the source/output relationship With converters, when I run Jekyll in server mode, if I change a SASS file it automatically runs the conversion to CSS. When dealing with concatenation/spriting, I haven't found a way to do the same. I end up having to run a "normal" Jekyll build (not server auto) to update the concatenated files and sprites. Thanks for any ideas!

  • How do I read text from a serial port?

    - by user2164
    I am trying to read data off of a Windows serial port through Java. I have the javax.comm libraries and am able to get some data but not correct data. When I read the port into a byte array and convert it to text I get a series of characters but no real text string. I have tried to specify the byte array as being both "UTF-8" and "US-ASCII". Does anyone know how to get real text out of this? Here is my code: while (inputStream.available() > 0) { int numBytes = inputStream.read(readBuffer); System.out.println("Reading from " + portId.getName() + ": "); System.out.println("Read " + numBytes + " bytes"); } System.out.println(new String(readBuffer)); System.out.println(new String(readBuffer, "UTF-8")); System.out.println(new String(readBuffer, "US-ASCII")); the output of the first three lines will not let me copy and paste (I assume because they are not normal characters). Here is the output of the Hex: 78786000e67e9e60061e8606781e66e0869e98e086f89898861878809e1e9880 I am reading from a Hollux GPS device which does output in string format. I know this for sure because I did it through C#. The settings that I am using for communication which I know are right from the work in the C# app are: Baud Rate: 9600 Databits: 8 Stop bit: 1 parity: none

  • Using Hidden Markov Model for designing AI mp3 player

    - by Casper Slynge
    Hey guys. Im working on an assignment, where I want to design an AI for a mp3 player. The AI must be trained and designed with the use of a HMM method. The mp3 player shall have the functionality of adapting to its user, by analyzing incoming biological sensor data, and from this data the mp3 player will choose a genre for the next song. Given in the assignment is 14 samples of data: One sample consist of Heart Rate, Respiration, Skin Conductivity, Activity and finally the output genre. Below is the 14 samples of data, just for you to get an impression of what im talking about. Sample HR RSP SC Activity Genre S1 Medium Low High Low Rock S2 High Low Medium High Rock S3 High High Medium Low Classic S4 High Medium Low Medium Classic S5 Medium Medium Low Low Classic S6 Medium Low High High Rock S7 Medium High Medium Low Classic S8 High Medium High Low Rock S9 High High Low Low Classic S10 Medium Medium Medium Low Classic S11 Medium Medium High High Rock S12 Low Medium Medium High Classic S13 Medium High Low Low Classic S14 High Low Medium High Rock My time of work regarding HMM is quite low, so my question to you is if I got the right angle on the assignment. I have three different states for each sensor: Low, Medium, High. Two observations/output symbols: Rock, Classic In my own opinion I see my start probabilities as the weightened factors for either a Low, Medium or High state in the Heart Rate. So the ideal solution for the AI is that it will learn these 14 sets of samples. And when a users sensor input is received, the AI will compare the combination of states for all four sensors, with the already memorized samples. If there exist a matching combination, the AI will choose the genre, and if not it will choose a genre according to the weightened transition probabilities, while simultaniously updating the transition probabilities with the new data. Is this a right approach to take, or am I missing something ? Is there another way to determine the output probability (read about Maximum likelihood estimation by EM, but dont understand the concept)? Best regards, Casper

  • Why does the add() method in PHP-GTK cause 2 parent-set signals to be emmitted?

    - by JW
    I am going through the book PHP-GTK and trying out listing 4-1 One thing I notice is that with the following code some odd output occurs: <?php //listing4-1b.php function setParentFunction($widget) { //get the widgets parent $parent = $widget->get_parent(); //echo a mssg about the widget echo 'The ' . get_class($widget) .' has '; if (isset($parent)) { //ech the class of the parent widget echo 'a '. get_class($parent); } else { //the widget does not have a parent echo 'no'; } echo " parent. \n"; } //start with widgets $frame = new GtkFrame('i am a frame'); $button = new GtkButton('i am a button'); //connect the event to our test function $button->connect('parent-set', 'setParentFunction'); $frame->add($button); ?> The output is: # php listing4-1b.php The GtkButton has a GtkFrame parent. The GtkButton has no parent. Now, I can understand why the first signal is getting emitted and causing the first line of output: The GtkButton has a GtkFrame parent. But, I don't understand why the 2nd 'parent change' is reported to have happened: The GtkButton has no parent. I expected only to see the signal getting emitted / and handled only once in this short script. Does this 2nd signal get emmitted when the script closes down?
