• Edit, select value from UITableView on the iPhone

  - by Anthony D

  I have a UITableView with a list of names, representing server configurations. I want the user to be able to select a server configuration, add a server config, edit a server config, or just cancel out of the view and return to the main view. I'm having a hard time trying to figure out how to achieve all of that functionality in this view. To select, the user should be able to just tap the server config name and a check will appear next to the name then the user is taken back to the main view automatically (or use a save button instead?). To edit the server config, I would also like the user to be able to tap the server config name and be taken to a detail screen where changes can be made. How can I accomplish both since I want both to be done by tapping the server name (row)? Right now the cancel button seems out of place since the screen is accessed via a UINavigationController. Any suggestions?

• Windows gadget in WPF - show while "Show desktop" is activated

  - by Jannick

  Hi I'm trying to create a "gadget" like application using WPF. The goal is to get the same behavior as a normal Windows 7 gadget: No task-bar entry Doesn't show up when you alt+tab windows NOT always on top, applications can be on top Visible while performing 'Aero Peek' Visible while using 'Show desktop' / Windows+D I've been able to accomplish the first four goals, but have been unable to find a solution to the fifth problem. The closest I've come is by using the utility class from http://stackoverflow.com/questions/75785/how-do-you-do-appbar-docking-to-screen-edge-like-winamp-in-wpf, but this turns the app into a "toolbar", thereby banishing applications from the part of the screen where my gadget GUI is placed. I can see that similar questions has been asked previously on Stackoverflow, but those have died out before a solution was found. Posting anyway in the hope that there is now someone out there with the knowledge to solve this =)

• BlackBerry - Custom centered cyclic HorizontalFieldManager

  - by Hezi

  Trying to create a custom cyclical horizontal manager which will work as follows. It will control several field buttons where the buttons will always be positioned so that the focused button will be in the middle of the screen. As it is a cyclical manager once the focus moves to the right or left button, it will move to the center of the screen and all the buttons will move accordingly (and the last button will become the first to give it an cyclic and endless list feeling) Any idea how to address this? I tried doing this by implementing a custom manager which aligns the buttons according to the required layout. Each time moveFocus() is called I remove all fields (deleteAll() ) and add them again in the right order. Unfortunately this does not work.

• Adding rows to UItableview and passing data between Viewcontrollers

  - by Jonathan

  I have a list of websites in a plist, when the app loads this populates a tableview (which is inside a navigation controller) But I have added an add button to the navigation bar and then created another View Controller to deal with inputting of the new website (Like Title and URL). It is very similar to how the contacts app looks. There is a table view and when you tap add, the add UI slides up. I have got all this working great so far. My Problem is what happens when the user taps Done. I can add the website to the plist (each website is a dictionary in the plist with 2 keys, atm) But then how do I tell the tableView to update? The table view has not been removed from the main window, just the add view has been added on top of the "screen". Another way of asking is, when you tap Save on Add a Contact screen: (not my image) How does the new contact's data (Xyz's data) get shown on the tableview?

• How can I make a grid of clickable images from a list of data in WPF?

  - by mico

  Hello, I am a seasoned C and Java programmer, but an absolute WPF newbie. I am creating a kiosk application that will display a list of images of products that the user will click to see product details and maybe place an order. I am trying to structure my app with MVVM Foundation because I am used to the benefits of structure and tests. I wonder what is the most natural way to create a grid of clickable images that will fill the screen left to right, top to bottom (or the other way round, I have no exact requirements). Any image should be bound to an object that will become current and be displayed in the next screen. Thanks for your help.

• Dynamically creating GWT screens using Metadata?

  - by Francis Shanahan

  I have an AWT applet application that needs to be ported over to GWT. The applet screens are described in meta data and the applet renders each screen dynamically using reflection. We'd like the same thing in GWT/ExtGWT. I've built a working version of this ExtJS whereby the metadata is turned into ExtJS Screen configs in the form of JSON. The drawback with this approach is the "wiring" of controls to data needs to be written in Javascript. GWT is preferred since it'd be all Java code, no JS. Upon digging in it's possible to render the screens using GWT off the metadata using GWT.create(). The problem I'm having is the wiring to hook a dynamically created button for example to an event handler requires reflection which is not supported in GWT. Is this conclusion correct? and if so, are there any other ways to achieve this type of dynamic UI using ExtGWT?

• Some animation requests in a Silverlight application

  - by Mohit Deshpande

  I am making a flash card application. It shows the question and then a textbox for user input, all wrapped in a border or rectangle. So what I want is an animation that "flips" the rectangle or border upside-down and then their is text on the "back". Also, I want my application to APPEAR transition from one card to another by "flying off" the screen then "another" card comes in to replace the other one in the opposite direction. But actually I'm want just a little animation of the border or rectangle moving off the screen then coming back in, but in the opposite direction.

• iPhone application-Memory handling issues

  - by Vin

  Hi All, I am having some memory management issues in my app. Maybe someone may help me out here. 1) While checking for leaks in intruments, when I deploy and run the app on device, the virtual memory utilized, starts from 50 MB(even though i've just launched the app and am on the first screen). My resources contribute to 2.6 MB of it and I don't know what is contributing for the rest. What is the ideal utilization of virtual memory for an app? 2) In certain screen of the app, user is allowed to click a picture from the camera. In Instruments, I observe that virtual memory utilization jumps around 20MB, on the invocation of camera. Is it normal and can it be decreased? Looking forward to hear a reply soon. Thanks in advance

• Show underlying applications mouse cursor when hovering over visible section of my application.

  - by Dylan Vester

  I am writing a WPF application that allows the user to draw over the entire screen when the right mouse button is held down. I use a full screen transparent overlay form to achieve this, however, as I draw lines with the mouse, what's happening is that the portion of my window that contains the line is becoming visible (as expected). The undesired effect of this is that if the line is over a part of another application such as a textbox, or hyperlink, this changes the cursor back to the default cursor my my app (arrow), instead of the other applications desired cursor (IBeam). I want my overlay to be seamless to the user, and just show their drawing path, rather than have any interaction with the mouse cursor. See my example below:

• How to compare two times in milliseconds precision?

  - by Marcos Issler

  I have a subtitle text file that works with standart srt format 00:00:00,000 Hour, minutes, seconds, milliseconds. I want to create a timer to update the subtitle screen and check the current time to know what subtitle show on screen. Which is the best to use? NSTimeInterval, NSDate? I think the best is to convert all to times to milliseconds number and compare. But NSTimeInterval works with seconds, not milliseconds. Some clue? Marcos

• HTML table headers always visible at top of window when viewing a large table

  - by Craig McQueen

  I would like to be able to "tweak" an HTML table's presentation to add a single feature: when scrolling down through the page so that the table is on the screen but the header rows are off-screen, I would like the headers to remain visible at the top of the viewing area. This would be conceptually like the "freeze panes" feature in Excel. However, an HTML page might contain several tables in it and I only would want it to happen for the table that is currently in-view, only while it is in-view. Note: I've seen one solution where the table data area is made scrollable while the headers do not scroll. That's not the solution I'm looking for.

• BlackBerry Storm - Cannot scroll vertically while in TreeField

  - by sethxian

  I am having issues performing a vertical scroll on the BlackBerry Storm while in a TreeField. The tree nodes expand just fine, even with expanded nodes while in the tree I cannot scroll to the bottom of the expanded list. Sometimes it will scroll a little but then not allow me to scroll back up. Could this be an issue with the screen not being a fixed size? The TreeField is in a VeriticalFieldManager with the VERTICAL_SCROLL and VERTICAL_SCROLLBAR styles. The screen I am using is MainScreen.

• Which Android phone to use for development...?

  - by Nikos

  Hi, I'm planning to port a couple of games from iPhone/Windows Mobile to the Android platform. The games are written in C++ so I plan to use the NDK with a thin java wrapper. I'm new to the Android platform and need some advice on which phone to buy for development. I suspect like Windows Mobile there is a level of fragmentation with different phones supporting different features (keyboard/ rotation/ screen size/ capacitive touch screen/ etc). What are the best device(s) for development on the Android platform...? They also have to be available in the UK/Europe. Thank you in advance. Nikos.

• Can I do video communication with silverlight 4.0?

  - by tom greene

  With silverlight 4.0, it is possible to show a live video of the user on the screen: Here is the code VideoBrush videoBrush = new VideoBrush(); CaptureSource captureSource = new CaptureSource { VideoCaptureDevice = CaptureDeviceConfiguration.GetAvailableVideoCaptureDevices().First() }; bool b = CaptureDeviceConfiguration.RequestDeviceAccess(); videoBrush.SetSource(captureSource); captureSource.Start(); myrect.Fill = videoBrush; However, I am looking at a way to show the video to someone else - seeing oneself on screen is not that interesting. Is it possible? Do I need my own server? Can I use clowd services to do the communication? Are there performance issues?

• iPhone: CALayer + rotate in 3D + antialias?

  - by Colin

  Hi all, An iPhone SDK question: I'm drawing a UIImageView on the screen. I've rotated it in 3D and provided a bit of perspective, so the image looks like it's pointing into the screen at an angle. That all works fine. Now the problem is the edges of the resulting picture don't seem to be antialiased at all. Anybody know how to make it so? Essentially, I'm implementing my own version of CoverFlow (yeah yeah, design patent blah blah) using quartz 3d transformations to do everything. It works fine, except that each cover isn't antialiased, and Apples version is. I've tried messing around with the edgeAntialisingMask of the CALayer, but that didn't help - the defaults are that every edge should be antialiased... thanks!

• How can I disable a view behind my SlidingDrawer in Android?

  - by Sara

  I have a SlidingDrawer that pops up from the bottom of the screen and fills the screen about 80%. Even though the SlidingDrawer view is in focus, it is still possible to click on items, buttons and other elements in the view that is behind the SlidingDrawer. When SlidingDrawer is active/pulled up/in focus, I want to disable the entire view behind it so it will not be able to recieve clicks and touches. Is there a good way to disable an entire view? I have tried setEnable(false) and setClickable(false) but neither of them work. Help?
