  • Allowing user to select a UIPickerView row by tapping.

    - by camilo
    Hi. I'm trying to use a UIPicker View with a behavior somehow different of what's usually seen in iPhone code examples. What I want to do is to allow users to scroll through the picker contents, but not to select a picker's row automatically (using the "didSelectRow" method from picker's delegate). Instead, I want to allow the user to touch the center row of the picker, which gets highlighted, and becomes the selection. Is there any way to achieve this? Thanks in advance.

  • Properly setting up willSelectRowAtIndexPath and didSelectRowAtIndexPath to send cell selections

    - by Gordon Fontenot
    Feel like I'm going a bit nutty here. I have a detail view with a few stand-alone UITextFields, a few UITextFields in UITAbleViewCells, and one single UITableViewCell that will be used to hold notes, if there are any. I only want this cell selectable when I am in edit mode. When I am not in edit mode, I do not want to be able to select it. Selecting the cell (while in edit mode) will fire a method that will init a new view. I know this is very easy, but I am missing something somewhere. Here are the current selection methods I am using: -(NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath { if (!self.editing) { NSLog(@"Returning nil, not in edit mode"); return nil; } NSLog(@"Cell will be selected, not in edit mode"); if (indexPath.section == 0) { NSLog(@"Comments cell will be selected"); return indexPath; } return nil; } -(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { if (!self.editing) { NSLog(@"Not in edit mode. Should not have made it this far."); return; } if (indexPath.section == 0) [self pushCommentsView]; else return; } My problem is really 2 fold; 1) Even when I'm not in edit mode, and I know I am returning nil (due to the NSLog message), I can still select the row (it flashes blue). From my understanding of the willSelectRowAtIndexPath method, this shouldn't be happening. Maybe I am wrong about this? 2) When I enter edit mode, I can't select anything at all. the willSelectRowAtIndexPath method never fires, and neither does the didSelectRowAtIndexPath. The only thing I am doing in the setEditing method, is hiding the back button while editing, and assigning firstResponder to the top textField to get the keyboard to pop up. I thought maybe the first responder was getting in the way of the click (which would be dumb), but even with that commented out, I cannot perform the cell selection during editing.

  • prevent UIWebView inputs from displaying UIKeyboard without disabling user interaction

    - by Slee
    I have a UIWebView that loads and external product configuration web service UI that is basically a bunch of dependent Drop Down lists. The problem is the Drop Downs are basically enhanced text input's so when the user taps them to display the options the UIKeyboard keeps popping up and own after they make their selection. it is less than a fluid process. Is there anyway to suppress the html inputs from triggering the UIKeyboard?

  • in flashbuilder (flex 4) select enclosing element

    - by core07
    Seems Adobe ignores strong movement now towards the productive programming. E.g. flash builder ide lacks keyboard shortcuts that are very useful in eclipse. If code templates, extract method, extract local variables are covered by some not-free plugins (and not cheap) like source mate, expanding selection to enclosing element I cannot find how to enable. Maybe you guys know some plugins doing that? Usually in eclipse it is Alt Shift Up to select enclosing block.

  • Generating a second context menu dynamically in Winforms

    - by rsteckly
    Hi, I have a context menu with a few selections. If the user picks a particular choice, I want a list of choices in a second menu to come up. These choices would be coming from a data store and be unique to that user. I see how in designer you can add a set of choices statically that show upon the user making a selection. However, what do you do when you need that to come from data and not design it in the designer?

  • problem binding ListBox on ObservableCollection<T>

    - by Fabian
    Hello, I have a strange "problem". Could someone explain me why : If I have in an ObservableCollection, twice (or more time) an item with the same value, then the selections of those values in the ListBox won't work properly ? In fact, what the ListBox is doing when I click on an item(Even in single item selection) : It selects the first item from the ObservableCollection collection with a matching value. so in the case if multiple items with same value are in the collection, then only the first one will be selected !

  • How Can I create different selectors for accepting new connection in java NIO

    - by Deepak
    I want to write java tcp socket programming using java NIO. Its working fine. But I am using the same selector for accepting reading from and writing to the clients. How Can I create different selectors for accepting new connection in java NIO, reading and writing. Is there any online help. Actually when I am busy in reading or writing my selector uses more iterator. So If more number of clients are connected then performance of accepting new coneection became slow. But I donot want the accepting clients to be slow // Create a selector and register two socket channels Selector selector = null; try { // Create the selector selector = Selector.open(); // Create two non-blocking sockets. This method is implemented in // e173 Creating a Non-Blocking Socket. SocketChannel sChannel1 = createSocketChannel("hostname.com", 80); SocketChannel sChannel2 = createSocketChannel("hostname.com", 80); // Register the channel with selector, listening for all events sChannel1.register(selector, sChannel1.validOps()); sChannel2.register(selector, sChannel1.validOps()); } catch (IOException e) { } // Wait for events while (true) { try { // Wait for an event selector.select(); } catch (IOException e) { // Handle error with selector break; } // Get list of selection keys with pending events Iterator it = selector.selectedKeys().iterator(); // Process each key at a time while (it.hasNext()) { // Get the selection key SelectionKey selKey = (SelectionKey)it.next(); // Remove it from the list to indicate that it is being processed it.remove(); try { processSelectionKey(selKey); } catch (IOException e) { // Handle error with channel and unregister selKey.cancel(); } } } public void processSelectionKey(SelectionKey selKey) throws IOException { // Since the ready operations are cumulative, // need to check readiness for each operation if (selKey.isValid() && selKey.isConnectable()) { // Get channel with connection request SocketChannel sChannel = (SocketChannel)selKey.channel(); boolean success = sChannel.finishConnect(); if (!success) { // An error occurred; handle it // Unregister the channel with this selector selKey.cancel(); } } if (selKey.isValid() && selKey.isReadable()) { // Get channel with bytes to read SocketChannel sChannel = (SocketChannel)selKey.channel(); // See e174 Reading from a SocketChannel } if (selKey.isValid() && selKey.isWritable()) { // Get channel that's ready for more bytes SocketChannel sChannel = (SocketChannel)selKey.channel(); } } Thanks Deepak

  • How to add a new node to a dijit.Tree

    - by Larry Bergman
    I want to add a new node to a dijit.ree as a sibling of the currently selected node. I've found sample code (I'm new to dojo) that adds a new item to the tree using the newItem method of ItemFileWriteStore, but the new item always appears at the bottom of the tree. How would I add to the store at a specified position, in particular the position corresponding to the current selection? Pointers to sample code would be welcome :) Thanks, Larry
