Module: WxRubyStyleAccessors

lib/wx/accessors.rb

Overview

WxSugar - Accessors

The default WxRuby interface has lots and lots of methods like

* get_position()
* set_size(a_size)
* is_checked()

and so on. Methods that retrieve set, or query attributes of an object are more normally in Ruby called simply by the attribute name:

* position()
* size = a_size
* checked?

This extension creates an alias for every WxRuby instance method that begins with get_, set_ or is_. Note that if you are calling a ‘setter’ method on self, you must explicitly send the message to self:

# set's self size to be 100px by 100px
self.size = Wx::Size.new(100, 100)
# only sets the value of a local variable 'size'
size = Wx::Size.new

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(sym, *args) ⇒ Object
