Currently, the latest version of the Hola desktop version 1.6, if you feel bad can wait for the official upgrade Oh.
1. If we install the Hola desktop click it to go to find "desktop settings"
2. In the setup we click on the "Set default desktop" after the blue button to open the entry, details as shown in the following figure
3. Then there will be a hint identified, we click "OK"
Drag Analysis of custom sliding folder like Hola desktop Launcher,
I haven't written a blog for a long time. I am still used to writing ideas. The idea is the most important.
Launcher's drag is nothing more than a DragController, which is simple and sometimes complicated. The following is a simple example of your understanding. You can point out what is wrong.
DragSource: drag the source, as the name implies, where it is dragged in. For example, from
In addition to support for importing Rube configurations, Hola Studio refers to the process of importing Rube configurations from previous Blog:hola Stduio. Editing the physical scene itself is also very convenient, here take a polygon edit example.Friends familiar with box2d know that polygon-resolved convex and concave polygons, which can be arbitrarily converted in Hola studio, in other words, you intuit

Tutorial on creating a custom Ruby gem package, rubygem
Write a simple example
1. Create the following folder
Note: The lib directory must have a rb file with the same name as your gem.
Copy codeThe Code is as follows:$ Cd hola$ Tree.├ ── Hola. gemspec── Lib└ ── Hola. rb
2. write code
. Hola. rb
% cat lib/hola.rb c
Write one of the simplest examples
1. Build the following folder
Note: The Lib directory must have a RB file that is the same as your gem name.
Copy Code code as follows:
$ CD Hola
$ tree
.
├──hola.gemspec
└──lib
└──hola.rb
2. Write Code
. Hola.rb
% Cat lib/hola.rb
class Hola
def self.hi
puts "Hello world!"
End End
. hola.gemspec

on MSDN, the interface only contains the method, delegate, or event signature. The more common explanation of this sentence is that the interface is only responsible for defining operations, rather than implementing specific details. The following IPlayer interface is an interface for playing games. It only defines the corresponding method without the specific implementation of the method. The Code is as follows:
1/** // 2 // game playing Interface3
Groups the objects in a list, using key-value pairs in groupsThe Nsdictionary nsmutabledictionary class creates a list of objects with keys.If you need to add or remove objects to the dictionary, use Nsmutabledictionary1 Creation of the dictionary Alloc constructor or Dictionarywithobjects:forkeysDictionaries created with nsdictionary cannot be changed once created, and dictionaries created with nsmutabledictionary can be changed.Nsarray *listofobjects=[nsarray arraywithobjects:@ "Hello World" @
, which naturally affects the upper layer, resulting in system instability, and even a pull. How can we reduce dependencies? That is, both the upper and lower layers depend on another abstraction. This abstraction is relatively stable, and the whole process is relatively stable.
B. object-oriented programming is aimed at abstraction or excuse-oriented programming. The abstraction is generally stable. The specific implementation of abstraction must depend on abstraction. abstraction should not de
Code is usually written by inheriting a class or implementing an interface. However, sometimes some code is only used once, so there is no need to write a specific subclass or implementation class. You can useAnonymous internal class. The most common scenarios are:ThreadApplications.1. Do not use anonymous internal classes① InheritanceAbstract class Player{Public abstract void play ();}Public class FootBallPlayer extends Player{Public void play (){System. out. println ("soccer ");}}Public class
relatively stable, the whole is more stable.B. Object-oriented programming for the abstract or for the pretext of programming, abstract generally more stable, to achieve the specific abstraction is to rely on abstract, abstract should not be dependent on other specific, should rely on abstraction.In the example above, we have found the dependency, and now we are going to optimize it according to the dependency inversion principle.Change according to the following principles:

State machine modeNow you need to create an APP that is simple as a video player, mainly including playing, pausing, and stopping three features. Before learning the state machine mode, you may implement this: abstract An IPlayer interface to define the actions and possible status fields to be implemented by your player: Copy code 1 public interface IPlayer {2 public static final int STATE_PLAYING = 1; 3 pu

In the player example above, we have found the dependency. Now we need to optimize the dependency according to the dependency inversion principle.
According to the following principles:
The player depends on mediafile, so that both the player and mediafile depend on an abstract imediafile.
Operationmain depends on the player. It is easy to implement. operationmain and player both depend on an abstract iPlayer.
