  • How to hide/show controls in UITableViewCell when it goes in/out of editing mode?

    - by Aleksandar Vacic
    I have few custom controls (image views) added programmatically to table cell. I want to hide them when table view goes into editing mode and show them again when view gets out of editing mode. I'm not using UITableViewCell subclasses, controls are added through tableView:cellForRowAtIndexPath: method. When and where should I do the hide/show? I'm wondering is this even possible without subclassing (where I could do this in layoutSubviews)...

  • fast sphere-grid intersection

    - by Mat
    hi! given a 3D grid, a 3d point as sphere center and a radius, i'd like to quickly calculate all cells contained or intersected by the sphere. Currently i take the the (gridaligned) boundingbox of the sphere and calculate the two cells for the min anx max point of this boundingbox. then, for each cell between those two cells, i do a box-sphere intersection test. would be great if there was something more efficient thanks!

  • UITableViewCell with selectable/copyable text that also detects URLs on the iPhone

    - by Jasarien
    Hi guys, I have a problem. Part of my app requires text to be shown in a table. The text needs to be selectable/copyable (but not editable) and any URLs within the text need to be highlighted and and when tapped allow me to take that URL and open my embedded browser. I have seen a couple of solutions that solve one of either of these problems, but not both. Solution 1: Icon Factory's IFTweetLabel The first solution I tried was to use the IFTweetLabel class made possible by Icon Factory and used in Twitterrific. While this solution allows for links (or anything you can find with a regex) to be detected to be handled on a case by case basis, it doesn't allow for selecting and copying. There is also an issue where if a URL is long enough to be wrapped, the button that the class overlays above the URL to make it interactive cannot wrap and draws off screen, looking very odd. Solution 2: Use IFTweetLabel and handle copy manually The second thing I tried was to keep IFTweetLabel in place to handle the links, but to implement the copying using a long-tap gesture, like how the SMS app handles it. This was just about working, but it doesn't allow for arbitrary selection of text, the whole text is copied, or none is copied at all... Pretty black and white. Solution 3: UITextView My third attempt was to add a UITextView as a subview of the table cell. The only thing that this doesn't solve is the fact that detected URLs cannot be handled by me. The text view uses UIApplication's openURL: method which quits my app and launched Safari. Also, as the table view can get quite large, the number of UITextViews added as subviews cause a noticeable performance drag on scrolling throughout the table, especially on iPhone 3G era devices (because of the creation, layout, compositing whenever a cell is scrolled on screen, etc). So my question to all you knowledgeable folk out there is: What can I do? Would a UIWebView be the best option? Aside from a performance drag, I think a webview would solve all the above issues, and if I remember correctly, back in the 2.0 days, the Apple documentation actually recommended web views where text formatting / hyperlinks were required. Can anyone think of a way to achieve this without a performance drag? Many thanks in advance to everyone who can help.

  • Excel Date to String conversion

    - by Chaitanya MSV
    Hi I have a Date value like 01/01/2010 14:30:00 in a cell in Excel sheet. I want to convert that Date to Text and also want the Text to look exactly like Date. So a Date value of 01/01/2010 14:30:00 should look like 01/01/2010 14:30:00 but internally it should be Text. How can I do that in Excel? Thank you! Chaitanya

  • Eclipselink read complex oject model in an ordered way

    - by Raven
    Hi, I need to read a complex model in an ordered way with eclipselink. The order is mandantory because it is a huge database and I want to have an output of a small portion of the database in a jface tableview. Trying to reorder it in the loading/quering thread takes too long and ordering it in the LabelProvider blocks the UI thread too much time, so I thought if Eclipselink could be used that way, that the database will order it, it might give me the performance I need. Unfortunately the object model can not be changed :-( The model is something like: @SuppressWarnings("serial") @Entity public class Thing implements Serializable { @Id @GeneratedValue(strategy = GenerationType.TABLE) private int id; private String name; @OneToMany(cascade=CascadeType.ALL) @PrivateOwned private List<Property> properties = new ArrayList<Property>(); ... // getter and setter following here } public class Property implements Serializable { @Id @GeneratedValue(strategy = GenerationType.TABLE) private int id; @OneToOne private Item item; private String value; ... // getter and setter following here } public class Item implements Serializable { @Id @GeneratedValue(strategy = GenerationType.TABLE) private int id; private String name; .... // getter and setter following here } // Code end In the table view the y-axis is more or less created with the query Query q = em.createQuery("SELECT m FROM Thing m ORDER BY m.name ASC"); using the "name" attribute from the Thing objects as label. In the table view the x-axis is more or less created with the query Query q = em.createQuery("SELECT m FROM Item m ORDER BY m.name ASC"); using the "name" attribute from the Item objects as label. Each cell has the value Things.getProperties().get[x].getValue() Unfortunately the list "properties" is not ordered, so the combination of cell value and x-axis column number (x) is not necessarily correct. Therefore I need to order the list "properties" in the same way as I ordered the labeling of the x-axis. And exactly this is the thing I dont know how it is done. So querying for the Thing objects should return the list "properties" "ORDER BY name ASC" but of the "Item"s objects. My ideas are something like having a query with two JOINs. Joing Things with Property and with Item but somehow I was unable to get it to work yet. Thank you for your help and your ideas to solve this riddle.

  • WPF 4 Datagrid with ComboBox

    - by Doug
    I have a WPF 4 app with a ComboBox embedded in a DataGrid. The ComboBox is in a template column that displays the combobox when in edit mode but just a TextBlock otherwise. If I edit the cell and pick a new value from the combobox, when leaving the cell, the TextBlock in view mode does not reflect the new value. Ultimately, the new value gets saved and is displayed when the window is refreshed but it does not happen while still editing in the grid. Here are the parts that are making this more complicated. The grid and the combobox are bound to different ItemsSource from the EnityFramework which is tied to my database. For this problem, the grid is displaying project members. The project member name can be picked from the combobox which gives a list of all company employees. Any ideas on how to tie the view mode of the DataGridColumnTemplate to the edit value when they are pointing to different DataSources? Relevant XAML <Window.Resources> <ObjectDataProvider x:Key="EmployeeODP" /> </Window.Resources> <StackPanel> <DataGrid Name="teamProjectGrid" AutoGenerateColumns="false" ItemsSource="{Binding Path=ProjectMembers}" <DataGrid.Columns> <DataGridTemplateColumn Header="Name" x:Name="colProjectMember"> <DataGridTemplateColumn.CellTemplate> <DataTemplate> <TextBlock Text="{Binding Path=ProjectMemberFullName}" /> </DataTemplate> </DataGridTemplateColumn.CellTemplate> <DataGridTemplateColumn.CellEditingTemplate> <DataTemplate> <ComboBox x:Name="ProjectMemberCombo" IsReadOnly="True" DisplayMemberPath="FullName" SelectedValue="{Binding Path=Employee}" ItemsSource="{Binding Source={StaticResource EmployeeODP}}" /> </DataTemplate> </DataGridTemplateColumn.CellEditingTemplate> </DataGridTemplateColumn> <DataGridTextColumn x:Name="colProjectRole" Binding="{Binding Path=ProjectRole}" Header="Role" /> </DataGrid.Columns> </DataGrid> </StackPanel> Relevant Code Behind this.DataContext = new MyEntityLibrary.MyProjectEntities(); ObjectDataProvider EmployeeODP= (ObjectDataProvider)FindResource("EmployeeODP"); if (EmployeeODP != null) { EmployeeODP.ObjectInstance = this.DataContext.Employees; }

  • Range subtraction in the Excel Object Model

    - by mcoolbeth
    When using Excel Interop libraries from .NET, I can find a Range object representing the cell offset from Range X by calling something like. Range Y = X.Range[2,3]; But what should I do to perform the inverse operation, ie: I have two Range objects, A and B, and I would like to find out by how many rows/columns B is offset from A. Does anyone know the easiest way to do this? Is there a library function? Thanks.

  • Bind DataGrid to Dictionary in ASP.NET

    - by mcoolbeth
    In ASP.NET, binding a DataGrid to a list of objects is super-easy. I end up with a row for each object in the list, and any cell in a given row is bound to a property of the corresponding object. However, suppose one of the properties of my object is a dictionary, and each is expected to contain a specific key. Is there any way to bind one of my DataGridColumns to that dictionary key? Thanks.
