components

It may be a simple question but how do I add multiple components to a UIPickerView? I use NSMutableArray to populate one component but I dont know how to populate the others. I also need to change the value of a label when a row is selected. Thanks in advance Kieran Tiquelou I take it that you are a beginner. Here's how to implement the methods nacho has rightly pointed out: - (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView { // return the number of components required return 2; } You can use other NSMutableArray 's to populate the components. Assuming that you have 2

Hi I want to create a splashscreen for an app, and have a gallery rotate several images on a timer. Can anyone show me how I could use a timer to animate the images in a Gallery? an easy solution would be private int PicPosition; private Handler handler = new Handler(); ... ... ... private Runnable runnable = new Runnable() { public void run() { myslideshow(); handler.postDelayed(this, 1000);\\execute every second. } }; private void myslideshow() { PicPosition = gallery.getSelectedItemPosition() +1; if (PicPosition >= Pictures.size()) PicPosition = gallery.getSelectedItemPosition(); //stop

I have this application that reuses a sort of idiom in a number of places. There's a TPanel, and on it are some labels and buttons. The purpose is to allow the user to select a date range. The "&Dates" caption is one label, and the "All Dates" part is a second one. When the user clicks the "Choose" button a form pops up presenting the user with a pair of Date/Time controls and OK/Cancel buttons. If the user hits OK after selecting some dates, the 2nd label changes to "From mm/dd/yyyy To mm/dd/yyyy". Is it plausible to create a component that packages up these controls? I have been looking at

As a follow on to an answered question on Adding Components Dynamically in JSF 2.0 (see link below), I like the approach of using a dataTable, but what about Removing one of the added components? How to dynamically add JSF components BalusC Based on the code snippet in the other question you linked, you need to do the following changes: Add a column with a delete button to the table. <h:column><h:commandButton value="delete" action="#{bean.delete}" /></h:column> Add a DataModel<Item> property to the bean and wrap the list of items in it so that you will be able to obtain the table row where

EDIT: The original question is still contained below, but I decided to re-title to a form that will be more useful to developers in a variety of cases, some of which described in my answer below, as the solution to the original problem turned out to provide a much wider area of application. I have a set of greyscale icons for an application, and a requirement that the icon color can be changed by the user. So, the obvious solution is to use the stock Colorize element from QtGraphicalEffects . The effect itself has a cached property - which caches the result of that particular effect so that it

I'm looking for a quality WinForms component that supports syntax highlighting, code folding and the like. The key criteria are: Stability Value (price) Ability to easily customize syntax to highlight Light weight ICSharpCode.TextEditor is free and pretty stable. As for commercial solution Actipro's SyntaxEditor might be a best choice Enhancing ICSharpCode.TextEditor was trivial compared with Scintilla.Net. Another huge benefit of ICSharpCode.TextEditor is that allows you to customize/build your own Syntax Highlighting, eg: https://github.com/icsharpcode/SharpDevelop/wiki/Syntax-highlighting .

I'm planning to buy CryptoLicensing but before buying it I'd like to get some feedbacks if anyone tried it before. Also it'd be interesting if anyone cracked it or spotted an easy hack against it. I've seen some other SO questions regarding the choosing a .NET licensing component but if you currently happy with another component it'd be nice to hear your experience. It's just quite hard to nail this without going through a long trial. I bought the licensing and obfuscator products from LogicNP and I'm quite satisfied. CryptoLicensing: The good: good value for your money. I didn't pay through

After using AS2 for several years, I'm getting started with writing applications in AS3 (Flash9/Flash10). I've come to the point where I need some full sets of GUI components, and I need to decide which set I'm going to use. Back in the AS2 days, the built in components included with flash were pretty crappy - bloated filesize, slow, buggy, etc. However, I heard good things about the new ones (included with CS3). So I'm looking for advice from people who have used a few different sets. Component sets I've heard of: CS3 Components - downside, I need to fiddle with the CS3 IDE, I'd prefer to
