  • Getting started on a stream interface driver

    - by Ranhiru
    I want to build a stream interface driver for testing purposes but I am completely lost. I don't know which IDE to use VS2008 or Platform Builder. Platform Builder is whopping 20GB to download :( Can anyone guide me on how i create the .dll file and include XXX_Open, XXX_Close, XXX_Write, XXX_Read in the dll file? Should i write the .dll file in C++ or can i write it in C#? Please guide me through the basics :) Thanx a lot :)

    Hi there, I have been designing with jquery and using the jquery UI widgets .. but always been designing for 1024 x 768 ... Is there any tricks or plugins (preferably that work with jquery UI) to automatically resize elements of my interface ... that way when somebody views it at a higher resolution it doesn't look so small.. Anybody have any tips on this? Thanks

  • Polishing an user interface

    - by elec
    Looking for examples of some "final touches" to enhance an existing (raw) user interface. I.e nothing related to the core functionalities of the application, but rather examples of all these little details which give an application a "polished" look (new fonts, change in layout, more descriptive labels...others ?) The target platform will be a mobile platform (android/iphone). Note that I'm severly graphically impaired regarding colour and shape combinations, so anything too sophisticated will probably pass me by completely ;)

  • Java: Interface vs Abstract Class (regarding fields)

    - by lifeR00t
    From what I have gathered, I want to force a class to use particular private fields (and methods) I need an abstract class because an interface only declares public/static/final fields and methods. Correct?? I just started my first big java project and want to make sure I'm not going to hurt myself later :)

  • Apple Interface Builder: adding subview to UIImageView

    - by kpower
    I created UIImageView with the help of Interface Bulder. Now I want to place label inside it (as its subview). In code I can type something like: [myUIImageView addSubview:myUILabel]; But can I do it with the help of IB? I found the solution for UIView, but can't find something similar for UIImageView.

  • segemented control in iphone not appearing as in interface builder

    - by zecougar
    here is what i see in IB and here is what appears in the simulator i've used a segmented control with style = "Bezelled". When i change the style to "Bar", IB and simulator are consistent in the display. the style is set in interface builder and not in code, if that matters Also - the edges look rather ugly in the simulator. not what i expected even when it rendered incorrectly. Thanks in advance

  • UIViewController takes up entire screen in Interface Builder

    - by Sheehan Alam
    I have a NIB with a UIView that contains some UILabels, UIButtons etc. and a UIViewController that is loading a detached NIB. I want the UIViewController to be positioned below my UIView, but whenever I add it in Interface Builder it takes up the whole screen, and my UIView becomes part of the UIViewController. How can I make sure UIViewController appears below the UIView?

  • Change the User Interface Language in Ubuntu

    - by Matthew Guay
    Would you like to use your Ubuntu computer in another language?  Here’s how you can easily change your interface language in Ubuntu. Ubuntu’s default install only includes a couple languages, but it makes it easy to find and add a new interface language to your computer.  To get started, open the System menu, select Administration, and then click Language Support. Ubuntu may ask if you want to update or add components to your current default language when you first open the dialog.  Click Install to go ahead and install the additional components, or you can click Remind Me Later to wait as these will be installed automatically when you add a new language. Now we’re ready to find and add an interface language to Ubuntu.  Click Install / Remove Languages to add the language you want. Find the language you want in the list, and click the check box to install it.  Ubuntu will show you all the components it will install for the language; this often includes spellchecking files for OpenOffice as well.  Once you’ve made your selection, click Apply Changes to install your new language.  Make sure you’re connected to the internet, as Ubuntu will have to download the additional components you’ve selected. Enter your system password when prompted, and then Ubuntu will download the needed languages files and install them.   Back in the main Language & Text dialog, we’re now ready to set our new language as default.  Find your new language in the list, and then click and drag it to the top of the list. Notice that Thai is the first language listed, and English is the second.  This will make Thai the default language for menus and windows in this account.  The tooltip reminds us that this setting does not effect system settings like currency or date formats. To change these, select the Text Tab and pick your new language from the drop-down menu.  You can preview the changes in the bottom Example box. The changes we just made will only affect this user account; the login screen and startup will not be affected.  If you wish to change the language in the startup and login screens also, click Apply System-Wide in both dialogs.  Other user accounts will still retain their original language settings; if you wish to change them, you must do it from those accounts. Once you have your new language settings all set, you’ll need to log out of your account and log back in to see your new interface language.  When you re-login, Ubuntu may ask you if you want to update your user folders’ names to your new language.  For example, here Ubuntu is asking if we want to change our folders to their Thai equivalents.  If you wish to do so, click Update or its equivalents in your language. Now your interface will be almost completely translated into your new language.  As you can see here, applications with generic names are translated to Thai but ones with specific names like Shutter keep their original name. Even the help dialogs are translated, which makes it easy for users around to world to get started with Ubuntu.  Once again, you may notice some things that are still in English, but almost everything is translated. Adding a new interface language doesn’t add the new language to your keyboard, so you’ll still need to set that up.  Check out our article on adding languages to your keyboard to get this setup. If you wish to revert to your original language or switch to another new language, simply repeat the above steps, this time dragging your original or new language to the top instead of the one you chose previously. Conclusion Ubuntu has a large number of supported interface languages to make it user-friendly to people around the globe.  And since you can set the language for each user account, it’s easy for multi-lingual individuals to share the same computer. Or, if you’re using Windows, check out our article on how you can Change the User Interface Language in Vista or Windows 7, too!

  • How can I separate the user interface from the business logic while still maintaining efficiency?

    - by Uri
    Let's say that I want to show a form that represents 10 different objects on a combobox. For example, I want the user to pick one hamburguer from 10 different ones that contain tomatoes. Since I want to separate UI and logic, I'd have to pass the form a string representation of the hamburguers in order to display them on the combobox. Otherwise, the UI would have to dig into the objects fields. Then the user would pick a hamburguer from the combobox, and submit it back to the controller. Now the controller would have to find again said hamburguer based on the string representation used by the form (maybe an ID?). Isn't that incredibly inefficient? You already had the objects you wanted to pick one from. If you submited to the form the whole objects, and then returned a specific object, you wouldn't have to refind it later on since the form already returned a reference to that object. Moreover, if I'm wrong and you actually should send the whole object to the form, how can I isolate UI from logic?

  • 12.04 boots fine, with graphical splash screen, but then Monitor "out of range"

    - by Jim Bednar
    I see dozens of posts from people whose monitors are saying "out of range" under Ubuntu; seems like there are some serious problems in Ubuntu with autodetection of monitor capabilities. :-( But none of the many, many suggestions I found have solved my problem, and right now I can't use anything graphical on this machine! History: I installed Ubuntu 12.04 on my HP Proliant Microserver N40L, which worked reasonably at the default resolution across several reboots. At some point I noticed that the proprietary video driver was not in use, and tried to install one to get better window-drawing speeds, but it failed with some sort of error, and I gave up on that. A few weeks later when I next rebooted, it showed the usual BIOS screen and various boot loading screens (including GRUB), and then the usual purple Ubuntu splash screen with the dots showing that things were loading, but when it finished booting the monitor went black and eventually showed "Out of range" (with no other information). Given that there were several weeks between reboots (it's a server, after all), I've no idea if it was some system update, trying to install the proprietary drivers, or something else that caused the problem. Anyway, the system has booted fine, as I can do Ctrl-Alt-F1 to get a text prompt and can log in there. But Ctrl-Alt-F7 goes back to the out of range error. Some posters said to try Ctrl-Alt-- (minus) to cycle through resolutions until one works, but that didn't have any visible effect. Many, many others said it was a grub problem, which seems unlikely given that grub's screen looks fine, but I tried editing /etc/default/grub to set a particular resolution (trying many of them) and running update-grub, with no apparent effect. Rebooting into failsafe mode works the same as regular mode. Replacing xorg.conf with xorg.conf.failsafe works the same too. I'm at my wits' end! Isn't there anything I can do to convince Ubuntu to choose a mode that the monitor supports? E.g. the one that it is using for the splash screen? I don't need great resolution on this machine, just anything that works!!!!! Help!!!!!! Please!!!!

  • What Interface Toolkit is being recommended for Ubuntu on Nexus7/Mobile Devices?

    - by Baggers
    I understand this is a may be a very premature question given that the current build is for testing Ubuntu Core, but I have just bought a Nexus7 to join in with this Ubuntu on mobile adventure and can't help wanting to start writing some apps! I haven't really dabbled with either GTK or QT for touch apps yet and, having seen that Ubuntu TV is using Nux, I wondered what people on AskUbuntu-land would recommend. Hope someone out there know this! Cheers

  • Java best practice Interface - subclasses and constants

    - by Taiko
    In the case where a couple of classes implements an interface, and those classes have a couple of constants in common (but no functions), were should I put this constant ? I've had this problem a couple of times. I have this interface : DataFromSensors that I use to hide the implementations of several sub classes like DataFromHeartRateMonitor DataFromGps etc... For some reason, those classes uses the same constants. And there's nowere else in the code were it is used. My question is, were should I put those constants ? Not in the interface, because it has nothing to do with my API Not in a static Constants class, because I'm trying to avoid those Not in a common abstract class, that would stand between the interface and the subclasses, because I have no functions in common, only a couple of constants (TIMEOUT_DURATION, UUID, those kind of things) I've read best practice for constants and interface to define constants but they don't really answer my question. Thanks !

  • Refactoring a leaf class to a base class, and keeping it also a interface implementation

    - by elcuco
    I am trying to refactor a working code. The code basically derives an interface class into a working implementation, and I want to use this implementation outside the original project as a standalone class. However, I do not want to create a fork, and I want the original project to be able to take out their implementation, and use mine. The problem is that the hierarchy structure is very different and I am not sure if this would work. I also cannot use the original base class in my project, since in reality it's quite entangled in the project (too many classes, includes) and I need to take care of only a subdomain of the problems the original project is. I wrote this code to test an idea how to implement this, and while it's working, I am not sure I like it: #include <iostream> // Original code is: // IBase -> Derived1 // I need to refactor Derive2 to be both indipendet class // and programmers should also be able to use the interface class // Derived2 -> MyClass + IBase // MyClass class IBase { public: virtual void printMsg() = 0; }; /////////////////////////////////////////////////// class Derived1 : public IBase { public: virtual void printMsg(){ std::cout << "Hello from Derived 1" << std::endl; } }; ////////////////////////////////////////////////// class MyClass { public: virtual void printMsg(){ std::cout << "Hello from MyClass" << std::endl; } }; class Derived2: public IBase, public MyClass{ virtual void printMsg(){ MyClass::printMsg(); } }; class Derived3: public MyClass, public IBase{ virtual void printMsg(){ MyClass::printMsg(); } }; int main() { IBase *o1 = new Derived1(); IBase *o2 = new Derived2(); IBase *o3 = new Derived3(); MyClass *o4 = new MyClass(); o1->printMsg(); o2->printMsg(); o3->printMsg(); o4->printMsg(); return 0; } The output is working as expected (tested using gcc and clang, 2 different C++ implementations so I think I am safe here): [elcuco@pinky ~/src/googlecode/qtedit4/tools/qtsourceview/qate/tests] ./test1 Hello from Derived 1 Hello from MyClass Hello from MyClass Hello from MyClass [elcuco@pinky ~/src/googlecode/qtedit4/tools/qtsourceview/qate/tests] ./test1.clang Hello from Derived 1 Hello from MyClass Hello from MyClass Hello from MyClass The question is My original code was: class Derived3: public MyClass, public IBase{ virtual void IBase::printMsg(){ MyClass::printMsg(); } }; Which is what I want to express, but this does not compile. I must admit I do not fully understand why this code work, as I expect that the new method Derived3::printMsg() will be an implementation of MyClass::printMsg() and not IBase::printMsg() (even tough this is what I do want). How does the compiler chooses which method to re-implement, when two "sister classes" have the same virtual function name? If anyone has a better way of implementing this, I would like to know as well :)

  • Terminology: Difference between software interface, software component, software unit, software modu

    - by JamieH
    I see these terms used quite a lot between various authors, but I can't seem to fix upon definitive definitions. From my POV a software interface is a "type" specifying the way in which a software component may be used by other softare components. But what exactly a software component is I'm not entirely sure (and it seems no-one else is either). Same goes for software unit, and software module, although I suspect that a software unit is a smaller, ahem, unit than a component, and a software module has something to do with packaging. I hope this is not deemed (and downvoted) as frivulous, as I have serious intent in the asking.
