  • Cocoa: How to make table view draw custom views in each cell

    - by Inso Reiges
    Hello, I am learning Cocoa and trying to create an application for Mac that displays a simple book list. Each book is an NSView with its cover image, title and author. I want to present this list as a NSTableView with a single column and a book view in each cell. However i can't yet figure out how to display a custom view inside a table cell in interface builder or programmatically. Any tips would be very appreciated :) Inso.

  • Show/hide views with checkbox

    - by DixieFlatline
    Hi! I want to show or hide some elements (textviews and edittexts) with checkbox. I set their visibility to gone in layout file. Showing them when user checks the box works, but the when user unchecks it, they don't hide. (android 1.5 and 1.6) My code: cb=(CheckBox)findViewById(R.id.cek); cb.setOnClickListener(new OnClickListener() { // checkbox listener public void onClick(View v) { // Perform action on clicks, depending on whether it's now checked if (((CheckBox) v).isChecked()) { tv1.setVisibility(0); //visible==0 et3.setVisibility(0); } else if (((CheckBox) v).isChecked() == false) { tv1.setVisibility(2); //gone=2 et3.setVisibility(2); } } });

  • JSF 2.0 Dynamic Views

    - by Robe Eleckers
    Hello, I'm working on a web project which uses JSF 2.0, PrimeFaces and PrettyFaces as main frameworks / libraries. The pages have the following (common) structure: Header, Content, Footer. Header: The Header always contains the same menu. This menu is a custom component, which generates a recursive html <ul><li> list containing <a href="url"> html links, this is all rendered with a custom renderer. The link looks like 'domain.com/website/datatable.xhtml?ref=2'. Where the ref=2 used to load the correct content from the database. I use prettyfaces to store this request value in a backingbean. Question 1: Is it ok to render the <a href> links myself, or should I better add an HTMLCommandLink from my UIComponent and render that in the encodeBegin/End? Question 2: I think passing variables like this is not really the JSF 2.0 style, how to do this in a better way? Content: The content contains dynamic data. It can be a (primefaces) datatable, build with dynamic data from the database. It can also be a text page, also loaded from the database. Or a series of graphs. You got the point, it's dynamic. The content is based on the link pressed in the header menu. If the content is of type datatable, then I put the ref=2 variable to a DataTableBean (via prettyfaces), which then loads the correct datatable from the database. If the content is of type chart, I'll put it on the ChartBean. Question 3: Is this a normal setup? Ideally I would like to update my content via Ajax. I hope it's clear :)

  • UIView Obscuring Other Views

    - by Matt Long
    I cannot figure out what is obscuring my buttons. The first image shows the buttons that I want to click. They are clickable while the view is contracted like this, but when the view is expanded like in the second image, the buttons are no longer clickable. There seems to be another view obscuring the buttons. Any thoughts on what might be causing that? If not, any idea how I can figure out what view is getting the tap events when I tap in that area? Thanks. -Matt

  • 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?

  • Who should call viewDidLoad on progammatically loaded views?

    - by Remus Rusanu
    When I need to load a view programatically I do the following: MyController* myController = [[MyController alloc] init]; [[NSBundle mainBundle] loadNibNamed:@"myNib" owner:myController options:nil]; // use my controller here, eg. push it in the nav controller This works fine, but my controller's viewDidLoad is never called. So I resorted to manually calling it after the loadNibNamed call, but it doesn't seem correct. I was expecting the framework to call the viewDidLoad on my behalf. Is this the right way or I'm missing something?

  • New to Android: Dynamically changing views

    - by Josiah Kiehl
    I'm trying to learn how to build apps for Android. The first simple app, which will become a component of a bigger app I hope to build, is to have a button on the screen where, when tapped, it adds something new to the view. For instance: Imagine a layout that only has a button: [Create!] When that button, the view gets a new row added to it: [Create!] A Something! Upon subsequent presses, more rows are added [Create!] A Something! A Something! And so on. I've made a LinearLayout and placed the button in it, and have attached a click listener to it. That all works great. What I can't figure out is how to get a handle on the LinearLayout in the onClick function with which I'll addView() the new TextView that says "A Something!" Am I on the right track? What basic thing am I missing? Thanks!

  • How to partially update views in an app widget without rebuilding all the RemoteViews

    - by Gianni Costanzi
    I'm implementing an app widget and I'd like to be able to change the property of a single view in the widget layout, without rebuilding all the RemoteViews from scratch, which involves loading XML etc and which is not necessary in some circumstances.. Is there a way to say "update property X on view identified by a specific ID in the current widget layout"? I've seen that there is a partiallyUpdateAppWidget method in the AppWidgetManager class but I can't understand nor if it is meant for this purpose neither how it must be used.. Can you help me or point me to a useful link or example?

  • Views jump during ViewDidLoad

    - by Jon-Paul
    Hi, I have a custom button, subclassed from UIButton that is initialised as below (obviously all the button does is use a custom font). @implementation HWButton - (id)initWithCoder:(NSCoder *)decoder { if (self = [super initWithCoder: decoder]) { [self.titleLabel setFont:[UIFont fontWithName: @"eraserdust" size: self.titleLabel.font.pointSize]]; } return self; } So far so good. But when I use the custom class in my nib and launch the app, the button initially displays for a split second as tiny with small text, then grows. So the outcome is what I want, but I don't want to see the transition. Can anyone put me right? Thanks. JP

  • Problem with my Jquery loading in my Codeigniter views

    - by sico87
    Hello, I am working on a one page website that allows the users to add and remove pages from there navigation as and when they would like too, the way it works is that if the click 'Blog' on the main nav a 'Blog' section should appear on the page, if they then click 'News' the 'News' section should also be visible, however the way I have started to implement this it seems I can only have one section at a time, can my code be adpated to allow multiple sections to shown on the main page. Here is my code for the page that has the main menu and the users selections on it. <!DOCTYPE html> <head> <title>Development Site</title> <link rel="stylesheet" href="/media/css/reset.css" media="screen"/> <link rel="stylesheet" href="/media/css/generic.css" media="screen"/> <script type="text/javascript" src="/media/javascript/jquery-ui/js/jquery.js"></script> <script type="text/javascript" src="/media/javascript/jquery-ui/development-bundle/ui/ui.core.js"></script> <script type="text/javascript" src="/media/javascript/jquery-ui/development-bundle/ui/ui.accordion.js"></script> <script type="text/javascript"> $(document).ready(function() { $('a.menuitem').click(function() { var link = $(this), url = link.attr("href"); $("#content_pane").load(url); return false; // prevent default link-behavior }); }); </script> </head> <body> <li><a class="menuitem" href="inspiration">Inspiration</a></li> <li><a class="menuitem" href="blog">Blog</a></li> <div id="content_pane"> </div> </body> </html>

  • Bind any version of MySql.Data using the app.config

    - by Martin Kirsche
    How do I bind any version or a range of versions of an assembly by using the app.config? I'm currently binding the MySql.Data assembly like this: <runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1" applies-to="v2.0.50727"> <qualifyAssembly partialName="MySql.Data" fullName="MySql.Data, Version=6.2.2.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d, processorArchitecture=MSIL"/> </assemblyBinding> </runtime> Any version of MySql.Data other than 6.2.2.0 is not working this way. The versions of this assembly are changing fast so I either want to bind any or all versions beginning with 6.2 to my application without changing the app.config each time.

  • MVP - asp.net - passing information via views - confused

    - by ekynox
    Hi, I've just started to play around with MVP in asp.net. One thing I quite cant figure out is how do I pass information, i.e. an integer variable from one view(webform) to another. Let's I have a customerlistView which is mapped to a customerlist.aspx page. From it I select a customer and it's record id. Say I want to display the customer's details in another view (i.e customerDetailView, customerdetail.aspx). How do I achieve that ? Does that mean customerlistView would call the presenter of the customerdetail and cause a page redirect ? Any ideas ? thanks

  • Forbid GridView to load all views at once

    - by efpies
    I have about 700 items to display in the grid view. On a Samsung Galaxy Tab 10.1 this is not a problem: it has enough memory. On a HTC Explorer the heap is overflown. So I want to load data dynamically regarding current scroll position (N rows for screen + 5 rows as a tail). And I want to show a scrollbar which represents the position in total rows. But I don't want to draw items that I don't see. In other words, I want to create something similar to UITableView in iOS. How can I do this?

  • UITouch Events and Table Views

    - by Andy
    I'm working on a navigation-based iPhone-only app that serves two main purposes: One, to present data in a hierarchical view, allowing users to drill down and eventually edit said data, and, two, to all users to perform a default action when the table view cell is tapped. I now need to offer a small set of options tied to the same data; however, both the didSelectRowAtIndexPath: and accessoryButtonTappedForRowAtIndexPath: methods are obviously taken. So, my options seem to be to implement a double-tap method, wherein the small list of additional options would be presented after (you guessed it) a double-tap on said table row; or, preferably, a tap-and-hold method. From what I can tell, tap-and-hold seems like the way to go in SDK 4.0 - which does me no good right this red-hot minute. I decided to go with the double-tap option, but I'm having a little trouble. First and foremost, the touchesBegan:withEvent: method does not seem to be getting called at all; a breakpoint placed within the method is never called while the application runs, and the table view responds exactly as it did before I inserted the method (which is to say, it performs the default action): - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *aTouch = [touches anyObject]; if (aTouch.tapCount == 2) { [NSObject cancelPreviousPerformRequestsWithTarget:self]; } } Second, I don't really need to handle a single-tap - the didSelectRowAtIndexPath: method can handle the single-tap just fine. The double-tap is the funky one I want to handle. I suspect the answer is going to contain the phrase, "You can't have the table view handle the single-tap and the touchesBegan: method handle the double-tap. The touch handling methods have to handle all of them." I would really appreciate some guidance from some of you who've dealt with this issue. Thanks in advance.

  • Add programmatically clickable Button with custom Views layouted in InterfaceBuilder

    - by allisone
    I have a UIScrollView. In there I add buttons programmatically. Right now I just use UIButton and set one title. But I need to have an UIImage View in there, that will change upon certain events, Text that will change too etc. and I would like to style that in Interface Builder, but I can't figure out how to do this. Which class should I extend, and what kind of xib should I create and what in there, so that in the end I can make the right connections and so that I can listen for UIControlEventTouchDown of that Button.
