• Looking for how-to use UIGraphicsSetPDFContextURLForRect on iOS or Cocoa

  - by user1676332

  I'm playing to manipulate PDF on iOS (display but also and mostly generation). I wish to embed rectangular areas which act as "external" links (URLs like http://host.tld/path/file). Do you know where I can find an example(s) of how to use the UIGraphicsSetPDFContextURLForRect function? I find absolutly nothing on Internet. If I understand well, the only requirement is that the current graphic context should be PDF "type" and I think I respect this since, upstream, I call UIGraphicsPushContext why my PDF context as parameter (this was anyway required for methods like drawAtPoint: that I use also with success). I do not think it is important but just in case I specify that this DOES NOT take place in the drawRect: of a View subclass. You're quite right to say me unequivocally that I have "all wrong". The graphical environment is so sophisticated and rich in iOS that I assume to have not assimilated more than 1 or 2% for now. Thank you in advance.

• How to create a bold and italic label in MFC?

  - by Hamish Grubijan

  Please do not mark it as a dupe of this question just yet: http://stackoverflow.com/questions/1881865/bold-labels-in-mfc That question does not help me; for some reason I do not see the rich edit control. Instead I believe I have to do it in code. here is a sample I found: http://www.tech-archive.net/Archive/VC/microsoft.public.vc.mfc/2006-10/msg00245.html My problem is that I prefer not to re-invent the wheel and test for errors myself or through QA. Someone must have implemented this before. Please share your code. What I would like to do is: Keep the same font size, family, etc. as in the already created label, but make it bold and italic as well. Keep the memory footprint reasonably low (do not create any new unnecessary objects), but do not get the app into an inconsistent state either. I appreciate your help.

• Form Design ScriptControlClass

  - by raghumithra

  I am working on a form designer. We have two parts: first is designing form by placing controls, and second is writing VB code in rich text editor. How do i integrate design and code (events of the controls) in runtime? I am using ScriptControlClass Form4 f4 = new Form4(); f4.Name = "dgfdfg"; f4.Text = "Raghudfgmithra"; Button btn = new Button(); btn.Text = "HI"; btn.Left = 25; btn.Top = 50; btn.Name = "btnSubmit"; f4.Controls.Add(btn); script.AddObject("form", f4, true); script.AddCode("???????????); script.ExecuteStatement(????????????);

• Can an app use the clipboard for its own purposes? (read: who owns the clipboard?)

  - by eran

  In PowerBuilder's IDE, the code autocomplete feature uses the clipboard to communicate the completed text to the code window. By doing so, it overrides whatever was stored on the clipboard before. So, if you had the winning numbers of the next lottary stored on your clipboard, and you used the autocomplete to turn m_goodfor into m_goodfornothing, you've just lost your only chance of ever getting rich, and you're left with nothing on your clipboard. Features like that are the reason I hate software. It looks like it was implemented by some intern that noone was looking after. However, there's also a chance I got all worked up for nothing, and making such use of the clipboard is absolutely legit. So, can an app use the clipboard for its own purposes? Who is considered the owner of the clipboard? (Bonus votes to whoever puts himself in place of the feature's programmer, and provides some reasoning for this being done on purpose, assuming the users would actually benefite from it)

• Which tutorial on Clojure is best?

  - by Steve Rowe

  I'm interested in learning Clojure. The Getting Started page on Clojure.net is pretty minimal. Is there a good language introduction or tutorial out there? Which would you recommend? Answer: I have watched the videos on youtube called Intro to Clojure. I don't recommend those. They are a little too brief and don't give a lot of background. The talks by Clojure creater Rich Hickey. I am finding the "for Java developers" version very useful.

• Java Framework Choice Question.

  - by Sarang

  We do have many frameworks available in Java. Struts, Swing, JSF 2.0, Spring etc are used as per their priority. Actually, I don't know how many they are as well! But, as I am fresher to Java, even learning after their architecture, I cannot decide which framework can be used with what type of Projects ! Also, I am confused with mixed use of framework like Spring + JSF. What is the benefit to it ? Another thing making me confusing is about the UI components available in market. Like, we do have Primefaces, Ice-faces, MyFaces, Rich-faces. They may or may not have been supporting AJAX in-built. They may contains some bugs as well. What is best choice for Framework + UI component that can directly provide a best feet solution for any project ?

• CueText equivalent for a TMemo

  - by JosephStyons

  I have this Delphi code to set the cue text of a control on my form: procedure TfrmMain.SetCueText(edt: TWinControl; cueText: string); const ECM_FIRST = $1500; EM_SETCUEBANNER = ECM_FIRST + 1; begin SendMessage(edt.Handle,EM_SETCUEBANNER,0, LParam(PWideChar(WideString(cueText)))); end; I want the same effect on a TMemo, but the MSDN document says: You cannot set a cue banner on a multiline edit control or on a rich edit control. Is there a standard way to have a cuetext effect on a TMemo, or do I have to fiddle with the OnEnter/OnExit events and roll my own?

• If you are forced to use an Anemic domain model, where do you put your business logic and calculated

  - by Jess

  Our current O/RM tool does not really allow for rich domain models, so we are forced to utilize anemic (DTO) entities everywhere. This has worked fine, but I continue to struggle with where to put basic object-based business logic and calculated fields. Current layers: Presentation Service Repository Data/Entity Our repository layer has most of the basic fetch/validate/save logic, although the service layer does a lot of the more complex validation & saving (since save operations also do logging, checking of permissions, etc). The problem is where to put code like this: Decimal CalculateTotal(LineItemEntity li) { return li.Quantity * li.Price; } or Decimal CalculateOrderTotal(OrderEntity order) { Decimal orderTotal = 0; foreach (LineItemEntity li in order.LineItems) { orderTotal += CalculateTotal(li); } return orderTotal; } Any thoughts?

• Accessing the value of a Richfaces calendar during validation.

  - by JBristow

  I am trying to validate a field based on another field's value. <h:form id="item"> <s:validateAll/> <h:selectBooleanCheckbox id="selected" value="#{bean.selected}" validator="selectedValidator"/> <rich:calendar id="startDate" value="#{bean.startDate}"/> </h:form> However, inside my validator. public void validate(FacesContext context, UIComponent component, Object value) throws ValidatorException { UIInput startComp = (UIInput) context.getViewRoot().findComponent("item:startDate"); if(value != null && value) { // Check value of startComp and throw exception if null or empty. } } The component startComp resolves, but has no value. Where is the value that appears in the text box of the richfaces calendar component?

• Fill a rails form with a hashmap

  - by Ignace

  Hey, I have a difficult situation. I let the the user create a form through a Rich Text Editor and then I save this. So for example, I save this literally into my DB: http://pastebin.com/DNdeetJp (how can you post HTML here? It gets interpreted, so now I use pastebin...) On another page I wrap this in a form_tag and it gets presented as it should be. What I want to do is save this as a template and save the answers as a hashmap to my DB. This works well, but the problem is I want to recreate what checkbox/radiobutton/... is selected when the user goes back to the page. So I want to fill the form with the answers from the hashmap. Is there a way to use a 'dummy' model or something else to accomplish this? Thanks!

• JSF implementations and component libraries

  - by Avinash Nandagiri

  I have just started using JSF and I have three questions related to JSF implementations and component libraries What is the difference between JSF Implementations and Component Libraries? What are the various JSF implementations (like Apache MyFaces) that are available and what is the difference between each one of them? What are the various JSF component libraries (like rich faces and ice faces) that are available and what is the difference between each one of them? Any relevant links giving the exact information on this would also be helpful. Thanks a lot in advance.

• .delegate equivalent of an existing .live method in jQuery 1.4.2

  - by kim3er

  I have an event handler bound to the hover event using the .live method, which is below: $(".nav li").hover(function () { $(this).addClass("hover"); }, function () { $(this).removeClass("hover"); }); It is important to note, that I require both functions within the handler to ensure synchronisation. Is it possible to rewrite the function using .delegate, as the following does not work? $(".nav").delegate("li", "hover", function () { $(this).addClass("hover"); }, function () { $(this).removeClass("hover"); }); Rich

• Default content editor in list form doesn't allow image alignment

  - by Ben Collins

  I need to be able to adjust the alignment of an image in an "Enhanced Rich Text Field" in an announcements list in MOSS 2007. However, the default content editor in the edit form for the list doesn't provide a way to do that. What's the fastest way for me to make sure users can align images? My first thought was to customize the DispForm.aspx and EditForm.aspx pages, but they just have the ListForm web part in the content region and as far as I know, you can't customize the ListForm web part from the designer.

• Delphi: How to diagnose sluggish UI?

  - by Ian Boyd

  i have a form, which you can pretend is laid out like Windows Explorer: panel on the left splitter client panel +------------+#+-----------------------+ | |#| | | |#| | | |#| | | |#| | | Left |#| Client | | |#| | | |#| | | |#| | | |#| | | |#| | +------------+#+-----------------------+ ^ | +----splitter The the left and client area panels are each rich with controls. The problem is that using the splitter is very sluggish. i would expect that a modern 2 GHz computer can re-display the form as fast as a human can push the mouse around. But that's definitely not the case, and it takes about 200-300 ms before the form is fully re-adjusted. The form has about 100 visual controls on it, no code, or custom controls. How do i go about tracing who's the cause of the sluggishness?

• Websites with horizontal sliding panels

  - by peterdp

  In a recent meeting, I mentioned that I've seen a few websites with horizontal sliding panels and thought the UI was elegant, uncluttered and accessible. Naturally, I was asked to provide examples of those sites, but can't seem to dig up any of them now. Actually, I've been looking on an off for the past few days. (blush) Sooo.... I thought that I would put it out to the brilliant and talented folks who frequent StackOverflow. If you know of a website -- or better yet, have a website -- that uses horizontal sliding panels to provide rich functionality while maintaining a clean UI, would you please take a few moments and paste links here? I'm sure it would be helpful to a bunch o' folks. Thanks so very much!

• how to organize javascripts using rails and jquery

  - by VP

  Hi, i'm working in a big and rich rails web application using tons of javascript. I would like to know if anybody has a tip to organize the javascripts. Today i'm generating a new file named controller.js and adding it to my views using content_for. The problem is, some files are becoming big and sometimes, i need a function from one controller in another, so then in the end, i add a products.js to a details controller just to keep DRY. Is that solution good? Any other tip? I think the same pattern can be applied as well to css files?

• Comparing YUI and Ext JS

  - by Spike Williams

  I've been using Ext JS as my rich-widget toolkit for a while, but I'm thinking of moving to YUI, partly because of the less restrictive license. The component-oriented model used in YUI seems quite similar to the one that I've enjoyed so much in Ext JS, but I'm interested in how deep those similarities are. So I'm interested in feedback from people who've used both Ext JS and YUI. What is the same, and what is different? What do I lose by moving to YUI, and what do I gain?

• Can my Facelets converter depend on a `ui:repeat` loop var?

  - by harto

  The following doesn't work as I'd hoped: <ul> <ui:repeat var="i" value="#{fn:split('1,2,3,4', ',')}"> <li> <h:outputText value="1.2345"> <f:convertNumber minFractionDigits="#{i}" maxFractionDigits="#{i}" /> </h:outputText> </li> </ui:repeat> </ul> I was hoping to see: 1.2 1.23 1.234 1.2345 Instead I see: 1 1 1 1 What am I missing? My real use-case involves a RichFaces rich:dataTable component instead of a ui:repeat, but the gist is the same.

• Formatting code snippets for blogging on Blogger

  - by nzpcmad

  My blog is hosted on Blogger and I frequently post code snippets in C / C# / Java / XML etc. but I find the snippet gets "mangled". Are there any web sites that I could use to parse the snippet beforehand and sort out the formatting, convert XML "<" to "<" etc. There are a numbers of questions around this area on SO but I couldn't find any that address this question directly. Edit: For @Rich answer, site states "To display the formatted code on your site, you need to get this CSS stylesheet, and add a reference to it in the section of your page". That's the problem - you can't do this on Blogger AFAIK.

• How to provide Input to Dialogs designed by Qt Designer

  - by GG

  Hello, I am a Qt beginner and working with Qt Designer to develop some small UI elements. I read http://doc.trolltech.com/4.5/designer-using-a-ui-file.html to use these GUI elements in my code and using multiple inheritance approach. I am introducing bookmark feature which somewhat look like http://img293.imageshack.us/img293/3041/screenshotyb.png. Now the problem I am facing is How can I show all existing bookmark folders in the drop down(say folders are in a QVector). So my main problem is how can I pass some inputs to the UI element. I think I'm clear, please let me know if further explanation is required. Sorry for adding links directly, rich formatting in my browser is not working. Thanks in advance,

• Best C++ Linux IDE [closed]

  - by Idan

  Possible Duplicate: Best unix/linux C++ debuger/IDE ? Hey, I've been searcing and reading about a good Linux C++ IDE, and couldn't set my mind on the right one. I've been using Eclipse with the C++ pluging , for C development, for the last couple months, but I found it not very useful, especially the debugging process that was quite annoying. I love Vistal Studio, so I'm looking for something really close to it. I need an IDE that will provide me, among other things: - rich debugging options - easy to use graphical designer - underscores error/warning (before I compile - like eclipse has) - Intellisense and more... Any suggestion? Maybe NetBeans?

• Spotlight search with PHP

  - by htf

  Hi. I want to add a spotlight search functionality - search results being displayed with rich contents like thumbnail etc in a drop down menu changing on each keyup event - just like the apple.com search - to a site, having data in MySQL InnoDB tables. The data is spread into separate tables for categories, help pages, blog pages and so on. The search script must take into account just a subset of columns. Since it seems to be a popular demand, I guess there are some PHP search engine projects (preferably open-source and with memcached support), which could be integrated into the existing system on the basis of regular exports of relevant data from the working db/tables. Are there any solutions out there? Which one would you recommend? Or maybe it would be better to implement it the other way around? Thanks

• Synchronising scripts / db / files from dev system to web server

  - by Spoonface

  I work as a freelance web dev, and up until now have been ftping my scripts / databases / static files to my web server manually, but I'm finding that is too error prone. So I'm looking for an app to automate uploading new and updated scripts / files / databases / etc. I know a lot of independent devs use WinSCP or Unison, but I don't think those apps can synch databases. Does anyone have any other suggestions? It doesn't need to be anything overly feature rich as I'm not working within a team or across multiple operating systems or anything like that. I can purchase any reasonably priced license if necesary. My work is primarily for PHP / MySQL / Apache on a Windows system, and then uploaded to a Linux / Apache server. thanks for your time!
