java - Nested class vs implements ActionListener -

-

There are benefits or drawbacks to creating a nested class that implement ActionListener: 

  Public square fu {Foo () {something.addActionListener (new button listener ()); } // ... Private class ButtonListener Apply ActionListener {Public Zero Action Action (ActionEvent E) {// ...}}}   
 vs. ActionListener applies only to the main category:  
  Public Squidoo ActionListener {Foo () {anything.addActionListener (this applies); } // ... Public Zero Effective Action (EVE) {// ...}}   
 I have seen both examples often, and just want to know if any 'most' good practice. '
 
 @nankor, you can still use anonymous internal classes as your listeners and are separate free-standing control classes and thus the code is Which is quite stable, I like to use a little bit of technique. For example:  
  import java.awt. *; Import java.awt.event. *; Import javax.swing *; Public class benamiinarig {Make private static blank and showwei () {GUIPANEL GUIPANEL = new GUIPANEL (); GuiControl guiControl = New GuiControl (); GuiPanel.setGuiControl (guiControl); GeFreem frame = new Jeffram ("benamiinerge"); Add frame.getContentPane () (guiPanel) .; Frame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE); Frame.pack (); Frame.setLocationRelativeTo (zero); Frame.setVisible (true); } Public static zero main (string [] args) {java.awt.EventQueue.invokeLater (new runnab) (public zero run) {createAndShowUI ();}}); }} Class Guipanel JPanel {Private GuiControl control; Public Guipanel () {JButton startButton = new JButton ("Start"); StartButton.addActionListener (New ActionListener) {Public Zero Action Action (ActionEvent e) {if (control! = Null) {control.startButtonActionPerformed (e);}}}); Jebton Endbutton = New Jebton ("End"); EndButton.addActionListener (new executable () {public zero action action (action event e) {if (control! = Tap) {control.endButtonActionPerformed (e);}}}); Adding (startButton); AddButton; } Public Zero Setgie Control (GuiControl Control) {this.control = control; }} Class GuiControl {Public Zero Start Button Action-Operated (Action Avenue) {System.out.println ("Start button pushed"); } Public Zero Ubuntu Action Perfid (Action Avenue) {System.out.println ("End button pushed"); }}

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.

Python's equivalent for Ruby's define_method? -

What is a Python equivalent for Ruby's define_method , which is the dynamic generation of class methods will allow? (As can be seen in Wikipedia) Functions are first-class objects in Python and assign them The properties of a class or an example can be a way of doing the same thing as a Wikipedia example: colors = {"black": "000", "red": "F00", "green": "0f0", "yellow": "ff0", "blue": "00f", "magenta": "fff", "cyan": "0ff", "white": " FFF "} Class MyStream (ARR): Pass for Name, Code in colors.iteritems (): def _in_colour ( W code = code): return '& lt; Span style = "color:% s" & gt;% s & lt; / Span & gt; ' % (Code, self) setter (histrive, "in_" + name, _in_ color)
