  • JXMapViewer change orientation to Heading Up

    - by Charlie
    I am trying to use JXMapViewer (from swingx-ws) with Open Street Maps. I was wondering if it would be possible to display the map tiles in the JXMapViewer based on heading up, rather than on North up. For example, the normal car GPS navigation systems let you do that. I've looked through the documentation and there doesn't seem to be a straightforward way to do this. Is there something else that accomplish this, besides JXMapViewer?

  • screen orientation problem in windows mobile application

    - by karim
    some one in tips and tricks say like this plz i cant understand that plz if u could provide saple code for that answer ,i could understand it.actullay iam facing this problem in my application where iam using C#.net,VS 2008,windows mobile 6 professional. they told like this below one If you have to support multiple screen sizes/resolutions, form inheritance is an excellent way to do it. Basically you design your form to fit the standard 320x240 screen. To support a different screen size, you just add a new form, inherit from your custom form (instead of just Form), and then re-arrange the controls as necessary.

  • iPhone SDK: Orientation (Landscape and Portrait views)

    - by domness
    Okay, I've got my normal app which is in portrait mode. I can force my app to go to landscape mode for a view (using navigationcontroller and viewcontroller) like this: - (void)viewWillAppear:(BOOL)animated { [[UIDevice currentDevice] setOrientation:UIInterfaceOrientationLandscapeRight]; } But then when I go back to the main menu (tableview) it goes straight back to portrait. I try this code: - (void)viewWillAppear:(BOOL)animated { [[UIDevice currentDevice] setOrientation:UIInterfaceOrientationPortrait]; } But that doesn't work.. Any ideas?

  • Passing an Object as an Interface

    - by Christopher Chase
    This should be a simple answer, i believe its going to be a no, but taken from a larger project, i have an interface and the procedure iMyUnknown= interface(IInterface) ['..GUID..'] end; procedure WorkObject(iObj :iMyUnknown); i know this works var MyUnknown : iMyUnknown; begin if supports(obj, iMyUnknown, MyUnknown) then WorkObject(MyUnknown); But is it possible to do something like this? if supports(obj, iMyUnknown) then WorkObject(obj as iMyUnknown);

  • What is the minimum interface that has the Count property in .Net

    - by SoMoS
    Hello, I need to change a method that has one parameter that takes a serie of objects. I need to find the lowest Interface (in inheritance tree) that has the Count property. Until now I was using the IEnumerable but as this has not Count I need to change it to the wider interface possible so the method can work with the biggest number of types of series (collections, lists, arrays, etc). Thanks in advance.

  • C# - Dynamic Keyword and Interface Implementations

    - by Adam Driscoll
    I'm assuming this isn't possible but before digging further is there a way to do something like this: public void ProcessInterface(ISomeInterface obj) {} //... dynamic myDyn = GetDynamic<ISomeInterface>() ProcessInterface(myDyn); I've seen a post arguing for it but it sounds like it wasn't included. A little context: .Net assembly exposed through COM - Silverlight app consuming interface-implementing classes. Would be nice to refer to the objects by interface. I really don't expect that this was what was intended...

  • ViewController has wrong orientation after Landscape-only has been popped

    - by noroom
    In a navigation-based app, LandscapeViewController only supports landscape mode (all others support both modes). I also have a "loading screen" that advises the user to rotate the phone before continuing. This way I can make sure that when my landscape view loads, that it's in landscape mode. The problem comes when i rotate the phone to portrait mode while still showing LandscapeVC. I press the Back nagivation button to navigate up one level (to a VC that supports both landscape and portrait modes), but the upper level shows in landscape mode even though the phone is in portrait mode. I guess this is because when I left this view I was in portrait mode, I then rotated the phone while in another view, so this view has not received the notification. If I then proceed to rotate the phone to the other landscape mode (say the LandscapeVC was loaded on its right side, so I'd rotate the upper VC from portrait to the left landscape mode), it will update. My question is: how can I notify this upper view that the phone was rotated, so when the user goes up after putting the phone in portrait mode, the upper view shows correctly?

  • IOS4 UISplitViewController in Portrait Orientation with RootViewController showing like Landscape

    - by magic-c0d3r
    In IOS 3.2 I was able to display my UISplitViewController side by side like in landscape mode. In IOS 4.2 the RootViewController (MasterView) is not showing up in portrait mode. Does anyone know if we need to display the rootviewcontroll in a popover? Can we display it side by side like how it is in landscape mode? I want to avoid having to click on a button to show the masterview (when in portrait mode)

  • Preserve HTML font-size when iPhone orientation changes from portrait to landscape

    - by DShultz
    I have a mobile web application with an unordered list containing multiple listitems with a hyperlink inside of each li: <ul> <li id="home" class="active"> <a href="home.html">HOME</a></div> </li> <li id="home" class="active"> <a href="test.html">TEST</a></div> </li> </ul> ...My question is how can I format the hyperlinks so that they DON'T change size when viewed on an iPhone, and the accellerometer switches from portrait - landscape? Right now, I have the hyperlink font size spec'ed to 14px, but when switching to landscape, it blows way up to like 20px. I want the font-size to stay the same. Here is the selector: ul li a { font-size:14px; text-decoration: none; color: #cc9999; }

  • Determining line orientation using vertex shaders

    - by Brett
    Hi, I want to be able to calculate the direction of a line to eye coordinates and store this value for every pixel on the line using a vertex and fragment shader. My idea was to calculate the direction gradient using atan2(Gy/Gx) after a modelview tranformation for each pair of vertices then quantize this value as a color intensity to pass to a fragment shader. How can I get access to the positions of pairs of vertices to achieve this or is there another method I should use? Thanks

    Can anyone recommend a good Ribbon interface library? I can see that Microsoft is (maybe) planning to release a native Ribbon interface library in Windows 7: http://www.istartedsomething.com/20080917/windows-scenic-new-ribbon-based-ui-platform/ But for now, which 3rd party libraries are the best?

  • iPad3 HD Black Screen in Portrait Orientation

    - by Jason Brooks
    I'm currently updating my game using XCode 4.3.1 and an iPad3. WHen iPAD HD mode is selected, I get a black screen when I change the scene from the AppDelegate. I'm using COCOS2d v1.0.1 My Game is portrait only mode, and I think I've tracked the problem down. If you create a new project with the default HelloWorld Layer, it works on the iPad3 and it's simulator in HD. However if you change the following code :- -(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { ... #elif GAME_AUTOROTATION == kGameAutorotationUIViewController // // EAGLView will be rotated by the UIViewController // // Sample: Autorotate only in landscpe mode // // return YES for the supported orientations //return ( UIInterfaceOrientationIsLandscape( interfaceOrientation ) ); return ( UIInterfaceOrientationIsPortrait ( interfaceOrientation ) ); //return NO; ... } In RootViewController.m You see a black screen for the iPad3 real device and simulator. It works as expected on all devices, iPhone/iPod Touch, and iPad 1 and 2. If I change the statement back to return ( UIInterfaceOrientationIsLandscape( interfaceOrientation ) ); I get the Hello World rendered to the screen, but it is in landscape only on iPad3. Has anyone else encountered this and have any suggestions for a fix? The project is quite large to upgrade to the latest V1 Beta code.

  • Problem Naming an Interface

    - by Jens Schauder
    I have an interface named PropertyFilter which used to take a Propertyand decide if accepts it or not. And the world was good. But now the interface changed, so that implementations may choose to add additional Propertys. For example a Customer property might get expanded into Name and Address properties. I think it is obvious this is not a Filter anymore, but how would you call such a thing?

  • How could I make the SurfaceView and Button have a different orientation in a Activity

    - by ???
    I hava a simple program about video recording . I use the surfaceView to show the preview screen. and I also want to put some buttons on the screen. I put all the component mentioned above into a XML file which is "ipcam.xml" I use MediaRecorder , SurfaceView , SurfaceHolder to complete this program because the preview screen does not orientate correctly when I rotate my phone. so I use "setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);" but , the button in the program is always in LANDSCAPE direction . it will not auto change direction when I rotate my phone , but the preview is ok!! so is there anyway to solve this problem. Thank you all very much in advance.

  • Set background of UITableview in interface builder?

    - by Martin
    In iPhone I need to set the background view of a UITableview. From 3.2 SDK I can in code use something like: [self.tableView setBackgroundView:[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"mycustombackground.png"]]]; But how can I do the same in interface builder? It would be great if I could just set the background view directly in interface builder. But can't seem to find this property, where is it? Thanks!
