  • What library to choose to build a user interface for a C++ software that uses SDL

    - by Barth
    Dear all, I have a simulation software (C++) that runs on the command line. It is platform independent (currently compiling and running on Windows, MacOS X and Linux). When the simulation ends, I visualize the result with SDL; it is a very basic 2d view, mainly color squares next to each other. I would like to have a user interface on top of the simulation so that I can start and pause the simulation, and change the parameters on the fly. Something pretty simple I guess. Well, ideally I will also add a grapher somewhere to see the evolution over time of some parameters. Now, I am wondering what direction I should go. Should I try to use one of the UI libraries for SDL ? Or maybe wxwidget in conjunction with SDL ? Or simply wxwidget and get rid of SDL ? Do you have any experience with this ? Thanks in advance Barth PS: I tried to use AGAR, a SDL UI library. It seemed very promising but I couldn't get it working. Not even the helloworld.

  • How can I simplify this user interface?

    - by Bears will eat you
    I'm writing an internal-tools webapp; one of the central pages in this tool has a whole bunch of related commands the user can execute by clicking one of a number of buttons on the page, like this: Ideally, all of the buttons would fit on one line. Ordinarily I'd do this by changing each widget from a button with a (sometimes long) text label to a simple, compact icon - e.g. could be replaced by a familiar disk icon: Unfortunately, I don't think I can do this for every button on this particular page. Some of the command buttons just don't have good visual analogs - "VDS List". Or, if I needed to add another button in the future for some other kind of list, I'd need two icons that both communicate "list-ness" and which list. So, I'm still considering this option, but I don't love it. So it's come time for me to add yet another button to this section (don't you love internal tools?). There's not enough room on that single line to fit the new button. Aside from the icon solution I already mentioned, what would be a good* way to simplify/declutter/reduce or otherwise improve this UI? *As per Jakob Nielsen's article, I'd like to think that a dropdown menu is not the solution.

  • Brighton Rocks: UA Europe 2011

    - by ultan o'broin
    User Assistance Europe 2011 was held in Brighton, UK. Having seen Quadrophenia a dozen times, I just had to go along (OK, I wanted to talk about messages in enterprise applications). Sadly, it rained a lot, though that was still eminently more tolerable than being stuck home in Dublin during Bloomsday. So, here are my somewhat selective highlights and observations from the conference, massively skewed towards my own interests, as usual. Enjoyed Leah Guren's (Cow TC) great start ‘keynote’ on the Cultural Dimensions of Software Help Usage. Starting out by revisiting Hofstede's and Hall's work on culture (how many times I have done this for Multilingual magazine?) and then Neilsen’s findings on age as an indicator of performance, Leah showed how it is the expertise of the user that user assistance (UA) needs to be designed for (especially for high-end users), with some considerations made for age, while the gender and culture of users are not major factors. Help also needs to be contextual and concise, embedded close to the action. That users are saying things like “If I want help on Office, I go to Google ” isn't all that profound at this stage, but it is always worth reiterating how search can be optimized to return better results for users. Interestingly, regardless of user education level, the issue of information quality--hinging on the lynchpin of terminology reflecting that of the user--is critical. Major takeaway for me there. Matthew Ellison’s sessions on embedded help and demos were also impressive. Embedded help that is concise and contextual is definitely a powerful UX enabler, and I’m pleased to say that in Oracle Fusion Applications we have embraced the concept fully. Matthew also mentioned in his session about successful software demos that the principle of modality with demos is a must. Look no further than Oracle User Productivity Kit demos See It!, Try It!, Know It, and Do It! modes, for example. I also found some key takeaways in the presentation by Marie-Louise Flacke on notes and warnings. Here, legal considerations seemed to take precedence over providing any real information to users. I was delighted when Marie-Louise called out the Oracle JDeveloper documentation as an exemplar of how to use notes and instructions instead of trying to scare the bejaysus out of people and not providing them with any real information they’d find useful instead. My own session on designing messages for enterprise applications was well attended. Knowing your user profiles (remember user expertise is the king maker for UA so write for each audience involved), how users really work, the required application business and UI rules, what your application technology supports, and how messages integrate with the enterprise help desk and support policies and you will go much further than relying solely on the guideline of "writing messages in plain language". And, remember the value in warnings and confirmation messages too, and how you can use them smartly. I hope y’all got something from my presentation and from my answers to questions afterwards. Ellis Pratt stole the show with his presentation on applying game theory to software UA, using plenty of colorful, relevant examples (check out the Atlassian and DropBox approaches, for example), and striking just the right balance between theory and practice. Completely agree that the approach to take here is not to make UA itself a game, but to invoke UA as part of a bigger game dynamic (time-to-task completion, personal and communal goals, personal achievement and status, and so on). Sure there are gotchas and limitations to gamification, and we need to do more research. However, we'll hear a lot more about this subject in coming years, particularly in the enterprise space. I hope. I also heard good things about the different sessions about DITA usage (including one by Sonja Fuga that clearly opens the door for major innovation in the community content space using WordPress), the progressive disclosure of information (Cerys Willoughby), an overview of controlled language (or "information quality", as I like to position it) solutions and rationale by Dave Gash, and others. I also spent time chatting with Mike Hamilton of MadCap Software, who showed me a cool demo of their Flare product, and the Lingo translation solution. I liked the idea of their licensing model for workers-on-the-go; that’s smart UX-awareness in itself. Also chatted with Julian Murfitt of Mekon about uptake of DITA in the enterprise space. In all, it's worth attending UA Europe. I was surprised, however, not to see conference topics about mobile UA, community conversation and content, and search in its own right. These are unstoppable forces now, and the latter is pretty central to providing assistance now to all but the most irredentist of hard-copy fetishists or advanced technical or functional users working away on the back end of applications and systems. Only saw one iPad too (says the guy who carries three laptops). Tweeting during the conference was pretty much nonexistent during the event, so no community energy there. Perhaps all this can be addressed next year. I would love to see the next UA Europe event come to Dublin (despite Bloomsday, it's not a bad place place, really) now that hotels are so cheap and all. So, what is my overall impression of the state of user assistance in Europe? Clearly, there are still many people in the industry who feel there is something broken with the traditional forms of user assistance (particularly printed doc) and something needs to be done about it. I would suggest they move on and try and embrace change, instead. Many others see new possibilities, offered by UX and technology, as well as the reality of online user behavior in an increasingly connected world and that is encouraging. Such thought leaders need to be listened to. As Ellis Pratt says in his great book, Trends in Technical Communication - Rethinking Help: “To stay relevant means taking a new perspective on the role (of technical writer), and delivering “products” over and above the traditional manual and online Help file... there are a number of new trends in this field - some complementary, some conflicting. Whatever trends emerge as the norm, it’s likely the status quo will change.” It already has, IMO. I hear similar debates in the professional translation world about the onset of translation crowd sourcing (the Facebook model) and machine translation (trust me, that battle is over). Neither of these initiatives has put anyone out of a job and probably won't, though the nature of the work might change. If anything, such innovations have increased the overall need for professional translators as user expectations rise, new audiences emerge, and organizations need to collate and curate user-generated content, combining it with their own. Perhaps user assistance professionals can learn from other professions and grow accordingly.

  • What's the best way to handle the same shortcut in WPF and WinForms controls?

    - by Anthony Brien
    I have a WPF application with the following KeyBinding on its main window: <KeyBinding Command="Commands:EditCommands.Undo" Gesture="CTRL+Z" /> <KeyBinding Command="Commands:EditCommands.Redo" Gesture="CTRL+Y" /> This makes the command respond to the shortcut fine. However, in all the places where I have embedded WinForms text boxes or rich text boxes, I've lost the ability to use those shortcuts. If I remove the above bindings, the WinForms shortcuts work fine. How can I support these shortcuts in both WinForms and WPF? I'd prefer a generic method since this problem is likely to affect many other commands with the same keybindings.

  • ADO Entity Framework 4 to WPF Datagrid. DatagridComboBox nightmare.

    - by Jason
    The WPF datagrid -seems- like it's going to work, but the combobox implementation does not work straight from the designer. So I'm left wandering around in the XAML randomly changing things trying to get it to work. The problems are numerous. I want to display a foreign key relationship (with drop down) instead of a bunch of numbers for a selection. It seems like it shouldn't be this hard. I can get the right values to show up (their description instead of an ID), but the table freaks out thinking that all the values have been modified. If I select a drop down, it refuses to allow me to edit anything else. I want to chalk this up as a .NET bug, but since I'm new to WPF datagrids, it's probably just me. Here is the code. <DataGridComboBoxColumn Header="Make Up" ItemsSource="{Binding Source={StaticResource materialMakeUpTypesViewSource}}" DisplayMemberPath="Description" TextBinding="{Binding Path=MaterialMakeUpType.Description}" SelectedItemBinding="{Binding Path=MaterialMakeUpType.Description}" SelectedValueBinding="{Binding Path=MaterialMakeUpType.ID}" />

  • How to use a App.config file in WPF applications?

    - by Edward Tanguay
    I created a App.config file in my WPF application: <?xml version="1.0" encoding="utf-8" ?> <configuration> <appsettings> <add key="xmlDataDirectory" value="c:\testdata"/> </appsettings> </configuration> Then I try to read the value out with this: string xmlDataDirectory = ConfigurationSettings.AppSettings.Get("xmlDataDirectory"); But it says this is obsolete and that I should use ConfigurationManager which I can't find, even searching in the class view. Does anyone know how to use config files like this in WPF?

  • Should I use WPF or ASP.NET for my next Web Application development?

    - by gap
    We have a web application that has been built using MySQL / PHP / Javascript+JQuery, with server-side HTML generation. The problem is that of the 10 software developers that work for the company, none are PHP experts (we're all .NET / C# developers). I need to make a recommendation to my management team on which technologies to use as the platform for the next generation of web application products. I want to leverage the .NET / C# expertise which the company has and is otherwise building, and so am inclined to recommend some Microsoft technologies. We don't want a client-side plugin, and we don't need flashy animations/multimedia, so I'm ruling out Silverlight. Is WPF ready for primetime? Is ASP.NET deprecated by WPF? How do I choose between these two technologies? Big Question, I know... I can refine it based on your comments if necessary. Thanks for taking the time.

  • VSS to TFS Migration - Persist User on check-in actions

    - by Adam Jenkin
    I am using the VSSConveter.exe tool to import from VSS6 (using 2005 ide) to TFS2008. I have run analyze (no errors) and migrate WITH a user mapping file (containg the vss/domain user mappings) I would like to persist in tfs the check-in user of the file, currently the check-in user for all versions of file shows as admin (the account im running the import with), the origional check-in user is appended to the check-in comment. For example:- TestFile.aspx in VSS Check in ver: 1 - User:Adam - Comment:TEST1 Check in ver: 2 - User:James - Comment:TEST2 Check in ver: 3 - User:Joel - Comment:TEST2 After import into TFS Check in ver: 1 - User:mydomain\Admin - Comment:TEST1 (Commited by Adam) Check in ver: 2 - User:mydomain\Admin - Comment:TEST2 (Commited by James) Check in ver: 3 - User:mydomain\Admin - Comment:TEST2 (Commited by Joel) In TFS I want the user to show as the correct domain user as configured in my user mapping file. Is this possible, or is this just how the VSSConverter program works?

  • How do I find all files and directories writable by a specific user?

    - by Pistos
    Under Linux, how can I find all the files and directories that are writable (or, actually, not writable) by a particular user? Edit: To clarify, I meant under a particular subdir, not systemwide. And yes, that means all the permutations and combinations of user, group and world writability that would allow that user to write. I know what the question entails semantically, I was hoping for a one- or few-liner to execute to get a list of these files.

  • Why are events and commands in MVVM so unsupported by WPF / Visual Studio?

    - by Edward Tanguay
    When creating an WPF application with the MVVM pattern, it seems I have to gather the necessary tools myself to even begin the most rudimentary event handling, e.g. AttachedBehaviors I get from here DelegateCommands I get from here Now I'm looking for some way to handle the ItemSelected event in a ComboBox and am getting suggestions of tricks and workarounds to do this (using a XAML trigger or have other elements bound to the selected item, etc.). Ok, I can go down this road, but it seems to be reinventing the wheel. It would be nice to just have an ItemSelected command that I can handle in my ViewModel. Am I missing some set of standard tools or is everyone doing MVVM with WPF basically building and putting together their own collection of tools just so they can do the simplest plumbing tasks with events and commands, things that take only a couple lines in code-behind with a Click="eventHandler"?

  • How to add children of an ItemsControl where the children should decide their own position in Wpf?

    - by code-zoop
    Hey all I am using a wpf slider to display the time line in a video player. I need to add an ItemControl of some sort on top of this so that I can add buttons on the time line on certain positions in the time line (the buttons will hold their own position relative to the parent ItemsControl). What ItemsControl container should I use where I can add child elements that know their own position (based on their timecode)? I have looked at the different ItemsControls in Wpf, and it looks like all of them have a certain way to stack their children (Horizontal or vertical one after another)! And to add some more complexity, How can the positioning of the children be relative to the width of the parent ItemsControl? This way scaling up and down the ItemsContol will reposition the children! Thanks

  • How can I keep a WPF Image from blocking if the ImageSource references an unreachable Url?

    - by Corey O'Brien
    I'm writing a WPF application and trying to bind an image to my view model with the following XAML: <Image Source="{Binding Author.IconUrl, IsAsync=True}" /> The problem is that the image URLs are defined by users and can often refer to images hosted on intranet web servers. When the WPF application is run remotely, it locks up while trying to resolve the images that are now unreachable. I thought the "IsAsync" binding property would cause the load to happen in the background, but it appears that the DNS resolution may still happen in the main thread? What can I do to keep my app from locking, even if the images are unreachable? Thanks, Corey

  • How do I get a TextBox to only accept numeric input in WPF?

    - by Giffyguy
    I'm looking to accept digits and the decimal point, but no sign. I've looked at samples using the NumericUpDown control for WinForms, and this sample of a NumericUpDown custom control from Microsoft. But so far it seems like NumericUpDown (supported by WPF or not) is not going to provide the functionality that I want. The way my app is designed, nobody in their right mind is going to want to mess with the arrows. They don't make any practical sense, in the context of my app. So I'm looking for a simple way to make a standard WPF TextBox accept only the characters that I want. Is this possible? Is it practical? Thanks, SO!

  • Text rendering still blurry : Best font for WPF application?

    - by Holli
    I know this is a very subjective question but as text rendering in WPF is still an issue I have to make the best out of it. In WPF Application text tend to become blurry that is no secret. Also there are countless website about this topic and how you get around this problem. But I wonder ... text blurriness seems to affect some fonts more that others. So I am still looking for the best font available to get around this issue. So far I am still using Arial and it doesn't look good. But I am sure some other font are more suitable for the task at hand.

  • How to stop a WPF binding from ignoring the PropertyChanged event that it caused?

    - by Jacob Stanley
    I have a TextBox bound to a ViewModel's Text property with the following setup: Xaml <TextBox Text="{Binding Text}"/> C# public class ViewModel : INotifyPropertyChanged { public string Text { get { return m_Text; } set { if (String.Equals(m_Text, value)) { return; } m_Text = value.ToLower(); RaisePropertyChanged("Text"); } } // Snip } When I type some stuff in to the TextBox it successfully sets the Text property on the ViewModel. The problem is that WPF ignores the property changed event that is raised by it's own update. This results in the user not seeing the text they typed converted to lowercase. How can I change this behaviour so that the TextBox updates with lowercase text? Note: this is just an example I have used to illustrate the problem of WPF ignoring events. I'm not really interested in converting strings to lowercase or any issues with String.Equals(string, string).

  • What is the accepted pattern for WPF commanding in MVVM?

    - by Robert S.
    I'm working on a WPF app and I understand the command pattern pretty well, but I've found that there are several different implementations of the command pattern for MVVM. There's Josh Smith's implementation in his WPF sample app, the DelegateCommand from Prism, and the CommandBindings implementation. My question is, what is the generally accepted best practice for using commands with MVVM? My application uses Prism so DelegateCommand is available to us. The devs on my team are arguing about which approach is "best." Some don't like the numerous .cs files generated for each command, others prefer that everything be wired up via CommandBindings. I'm at a loss. Can anyone shed some light?

  • wpf - Which one is better? Style or User Control?

    - by Archie
    Hello, I wanted to know which one amongst Style and UserControl would be better to use in WPF? For example: I have created an image button in two different ways. One uses Style and ContentTemplate property is set. It uses one other class with dependency properties. The other way is i have created a UserControl which has a button and its content property is set. UserControl.xaml.cs file also contains the dependency properties. For Code details see the answers of this question: http://stackoverflow.com/questions/2734825/custom-button-template-in-wpf Which one would be better to use? Can anyone tell me in which scenario one should go for Style or UserControl or any CustomControl? Thanks in advance.

  • Can you run a specific tomcat Web Application under another user?

    - by Boaz
    Hi, We're developing a web-app running under tomcat which relies on Java User preferences to store all kind of settings. That works great, but we've run into problem where we needed to set up another staging web-app which allows you to test settings before settings them live. The core of the problem lies in the fact that Java User preferences are the same for all web-app due to the fact that all of them run under the tomcat user (configurable). For legacy reasons I can not at the moment change my preferences structure, so I'm hoping for a solution on the the tomcat configuration side. Is it possible to designate a different user credentials for a specific web-app in tomcat? Thanks, Boaz

  • Any issues with computer on one domain in a separate forest and user account in another domain/forest?

    - by TheCleaner
    I have a few of my sites with a trust relationship among two different forests with a single domain in each AD forest. I'll skip all the politics and details that don't matter and just ask the question: Will having a machine with a computer account in one domain and their user account in another cause any issues? (besides GPO behavior that would need to be understood such as their computer getting a GPO applied from the computer's domain, and their user account getting a GPO applied from their user domain)

  • How do I work with WIndows Forms in WPF?

    - by xarzu
    How do I work with WIndows Forms in WPF? In my WPF program I created a Windows Form class. In this Form, I placed an OK button and I went into the properties of the button and set the DialogResult to OK. Now, I am calling this Dialog (Window Form) from the MainWindow.xaml.cs: dres = form.ShowDialog(); if (dres != DialogResult.OK) return; The compiler is complaining: Error 3 'System.Nullable<bool>' does not contain a definition for 'OK' and no extension method 'OK' accepting a first argument of type 'System.Nullable<bool>' could be found (are you missing a using directive or an assembly reference?)

  • How can I get to the value of my WPF UserControl DependencyProperty from UI Automation Framework?

    - by Surfbutler
    Hi, I'm having trouble getting access to my WPF UserControl DependencyProperty values through the UI Automation Framework. I've used James McCaffreys article in MSDN as a starting point (Automating IO Tests in WPF Applications, MSDN March 2009), but I can only see properties etc in standard controls such as buttons. I'm assuming there's some Automation interface I have to implement on my UserControl, but what and how? I can already see my control fine e.g. in UISpy, but I can't see the dependency properties within it. Here's what my usercontrol looks like currently in UISpy: AutomationElement General Accessibility AccessKey: "" AcceleratorKey: "" IsKeyboardFocusable: "False" LabeledBy: "(null)" HelpText: "Switches 48v Phantom Power On/Off (for Mic inputs only)." State IsEnabled: "True" HasKeyboardFocus: "False" Identification ClassName: "" ControlType: "ControlType.Custom" Culture: "(null)" AutomationId: "V48SwL" LocalizedControlType: "custom" Name: "" ProcessId: "5684 (VirtualSix)" RuntimeId: "7 5684 40026340" IsPassword: "False" IsControlElement: "True" IsContentElement: "True" Visibility BoundingRectangle: "(140, 457, 31, 20)" ClickablePoint: "155,467" IsOffscreen: "False" ControlPatterns

  • Where should I put WPF specific code when using MVVM?

    - by Surfbutler
    I'm just getting up to speed on MVVM, but all the examples I've seen so far are binding View controls to simple non-WPF specific data types such as strings and ints. However in our app I want to be able to set a button's border brush based on a number in the Model. At the moment, I translate the number into a brush in the ViewModel to keep the View XAML only, but is that right? I don't like putting WPF specific code in the ViewModel, but equally I don't like the idea of putting code-behind on my View panel. Which is the best way? Thanks
