In Xcode 4.x is there a way to quickly add method stubs for a delegate or dataSourceDelegate?
Right now if I'm adding an UI component like a UI picker view I need to lookup the protocol in the header and then create those methods.
Is there some handy way of saying add the required and optional stubs to my .m for a given delegate protocol? Without translating copy+paste and adapt from the protocol declaration.
This SO question What is the most efficient way in XCode to add a delegate's or protocol's methods to the .m file? talks about cut and paste from Xcode3 and that's always how I've done it but I'm wondering if there is a slicker approach in Xcode4.
You could create your own stubs and add them to Xcode's Code Snippet pane. To create a new snippet, highlight the relevant section of your code, and click and drag into the code snippets pane. Then to use them, simply drag and drop snippets into your code. I've heard you can set a completion prefix too so that the snippet will come up in autocomplete.

We need a tree view with File system and check boxes in QT. Is there any way to achieve that?
The tree we need would look something like below:
UPDATE:
I am able to achieve it with subclass of QFileSystemModel. Still have few challenges, but at least subclass is working. Below is the code if anyone needs it. Below is the link to the code -
https://drive.google.com/file/d/1qViZ3iEW2pV2th0jQhzneDL14SEhIgS0/view?usp=sharing
The pending work is to apply a wait cursor (or make treeview uneditable when the check/uncheck is taking place).
PS: It will take a lot of time if root node is checked.
Well, all of that can be achieved with minimal customizations of built-in classes, actually those checkboxes is almost the only thing that has to be done yourself.
QFileSystemModel already provides a proper model for displaying the current filesystem contents, it can be subclassed
As for QML, the best demo is already provided by Qt, check the File System Browser Example. This example uses some deprecaded Qt functionality, but still it shows the basic concept.
The modern techniqes can be also found in the answers to the following question: Qt File Browser based on QML
Hopefully, all that helps you, good luck!
I created a simple form object representing some arbitrary name and value pair:
It's intentionally very simple - any design is to be applied through the CSS styles. Apart from the UI, the form consists of C++ class that handles the data loading and custom property defined in Designer too - the name of the data source (eg. hostname).
So I have two values I need to parametrize:
the Name - the QLabel text
the datapoint - some hostname. This will be later loaded by the C++ class and tell it what data should be loaded
I was Imagine I would be able to create "instances" of my form manually in designer and assign parameters to them. Like in this fictional image:
Don't forget datapoint is the custom dynamic attribute. I am sure the described design can be easily carried out programatically, but I feel like the designer solution will be prettier - provided there's a legit way to do it.
Maybe it's wrong, but the only way I can think of is making your Qt Designer aware of your widget. Something like this.
AFAIK, widget propagation doesn't allow you to edit custom properties without code, so you need a full widget support. My colleagues intentionally do whatever posiible from sources, not IDE& Forms, so that the project becomes more portable, but you are to choose yourself.
I designed a Qt application by Qt creator. As you well know when you build a new form is possible to drag an drop the default items inside the main window. Instead of use classical "push button" I created a custom button by adding .qml file to the project. The problem now is that I don't know how I can use (or integrate) the new button inside the form of my project.
Thanks in advance
As long as your component is in the path of your application qml files, all you need to use your component is to place it somewhere. You don't need to include or import anything. Any user component is directly available to the entire project.
As long as the QML component is made from only built in components, it can even be safely loaded from arbitrary location on disk, over network or just from a source string. Check this answer for details on dynamic instantiation.
A friendly advice - type the code, do not use the visual editor - it is pretty weak.
EDIT: I don't know about you, but for me, seems like every custom qml file in the project qml folder is automatically added to the QML types in the designer library. So contrary to what I assumed, you shouldn't really need to do anything to get your custom type available for use in the designer.
I found this 1 year-old question when facing the same problem. This is what I found out:
If you save your custom button with an initial uppercase letter (CustomButton.qml instead of customButtom.qml), QtDesigner shows your component in the library panel correctly.
Sometimes you need to restart QtDesigner to work.
I would like to make an input method which is used only for Qt desktop application.
It like Chinese(Pinyin) input method in windows. Include script processing, rendering of words.
As it includes rendering of words, it can't be created with Keyboard Layout.
More over, when built-in with application, it can be use cross over other platform.
But, It not like on-screen keyboard.
Thanks for all
The Qt way to implement this is to provide an input method plugin, see general plugin development docs and the input method specific base class.
With this you should be able to implement your own input method. Stuff like script processing and rendering is then up to your own plugin.
I need to make small asp.net application in codecharge.
Please tell me how to add server side event into that app and how can i get textbox value in server side.
Have you had a look through the examples here:
http://examples.codecharge.com/
This is going to sound like 'RTFM' but... the Help file that comes with Codecharge is quite extensive and goes through many of the common tasks (in the case of CodeCharge Studio (CCS), it does it for each language - PHP, .NET, perl, JSP, coldfusion, ASP). See the links below for the online version.
An example of using the Server Side events (Before Insert) to modify a control's value is shown in all languages (see 'Replace Control Value Before Inserting' and choose your project's language at top-right of page).
As with most frameworks, a lot of the gathering of POST values from controls are already done and ready to use at run-time. CCS has lists of the properties and methods of its 'components' in the Help as well. Most languages have something like 'GetValue()' in their run-time properties - check the Text Box Component Reference section of the Help. For .NET it's 'GetFormattedValue()'
CCS also has a lot of pre-built 'Actions' to use in the Events - so in a lot of cases you don't need to code it yourself, there may be an Action to Help. You can also choose an Action, get CCS to make it, double-click on the Action, and view the generated code for tips. You could then delete the Action (don't delete the code, delete the Action and let CCS remove the actual code) and you can then add 'Custom Code' and put in your own. I have used that method when learning a new language in CCS.
You use within an event on the server.
