#PXSourceList
|
||||
|
||||
A Source List control for use with the Mac OS X 10.5 SDK or above.
|
||||
|
||||
[Download the documentation][1]
|
||||
|
||||
##Intention
|
||||
[Source Lists][2] are used in a lot of Mac OS X applications, but the support for such controls is quite primitive – at best you create an Outline View with Source List highlighting, but none of the features such as badging are built in by default. `PXSourceList` is a reusable control – within the context of Source Lists – which makes creating applications with Source Lists a much easier process.
|
||||
|
||||
##Using the code
|
||||
There are only a few steps involved:
|
||||
|
||||
1. Download the source, and copy `PXSourceList.h`, `PXSourceList.m`, `PXSourceListDelegate.h` and `PXSourceListDataSource.h` into your Xcode project.
|
||||
2. To create the control in Interface Builder, drag an `NSOutlineView` object over to a window and in the Identity Inspector for the Outline View, change the class to `PXSourceList`. In the Attributes Inspector, set it to have only 1 column, uncheck "Headers" in the "Columns" section and set "Highlight" to "Source List" – there is an NIB in the example project bundled with the source.
|
||||
3. Make sure to `#import "PXSourceList.h"` for files that require it (the delegate and data source protocol files are imported in this main header), and ensure that your class(es) that are the `delegate` and/or `dataSource` for the Source List conform to the `PXSourceListDelegate` and `PXSourceListDataSource` protocols respectively.
|
||||
|
||||
**Note:** If you intend to use PXSourceList with the 10.5 SDK, you will need to remove some of the protocols that PXSourceList conforms to which do not exist – in `PXSourceList.h`, remove the `<NSOutlineViewDelegate, NSOutlineViewDataSource, NSMenuDelegate>` from the interface declaration.
|
||||
|
||||
There is also an example project bundled with the source to see how the control is used.
|
||||
|
||||
##How the control works
|
||||
I have tried to structure PXSourceList in a way such that it fits common Cocoa design patterns and therefore makes it easier to use.
|
||||
|
||||
PXSourceList adapts the delegate and data source design patterns, and extends those of the `NSOutlineViewDelegate` and `NSOutlineViewDataSource`, much in the way that these extend the appropriate `NSTableView` protocols.
|
||||
|
||||
If you want more information have a look at the [Outline View Programming Topics for Cocoa][3] – the Source List delegate and data source implementation work in much the same way, but with methods added and removed, as detailed in the documentation.
|
||||
|
||||
##Documentation
|
||||
Documentation is available for PXSourceList, downloadable [here][4]. Provided in the ZIP file is a folder containing HTML documentation, or a docset which can be opened in Xcode and which is then searchable from the Xcode Developer Documentation.
|
||||
|
||||
If you feel that any areas of the documentation are lacking or missing, please feel free to [let me know][5], which will be much appreciated.
|
||||
|
||||
**Note:** the documentation for the Source List notifications can be found in the `NSObject(PXSourceListNotifications)` reference, which is linked to from the documentation index page.
|
||||
|
||||
##Known Issues
|
||||
|
||||
- Calling `delegate` or `dataSource` on the Source List returns the Source List instance. This is, unfortunately, a side effect of how delegate and data source methods are handled within the Source List – I hope to work around it in the future.
|
||||
- No bindings implementation (yet).
|
||||
|
||||
##Attribution
|
||||
|
||||
I was spurred along the way by many sources, but in particular [BWToolkit][6] by Brandon Walkin and Fraser Kuyvenhoven, which gave me the idea of how to handle the Source List delegate and data source methods.
|
||||
|
||||
Also Brian Dunagan's post on [Source List badging][7] and determining state for the various colours was a great help when I came to the drawing code for that.
|
||||
|
||||
The documentation was created using [Doxygen][8] and [appledoc][9], thanks of which go to the developers of both.
|
||||
|
||||
The icons used in the demo project bundled with the source code are from the [Fugue icon set][10] by Yusuke Kamiyamane.
