wxpython学习笔记

1、wx文档查阅：

详细说明：http://wxpython.org/Phoenix/docs/html/index.html

快速查阅索引：http://www.wxpython.org/docs/api/wx-module.html

电子书：wxpython in action

2、为了便于找到资源文件，使当前工作目录与源文件所在位置相同：

os.getcwd()获取当前工作目录；

os.path.dirname(...)获取源文件路径中所在的目录；

os.chdir()改变当前工作目录。

import os
print(os.getcwd())
import sys
os.chdir(os.path.dirname(sys.argv[0]))
print(os.getcwd())

3、关于大图标和小图标：

Windows分两种图标，Linux只有一种。

显示小图标：icon = wx.Icon(name="ICONDEMO.ICO",
type=wx.BITMAP_TYPE_ICO,desiredWidth=16,desiredHeight=16)；

由文档：desiredWidth (int) – Specifies the
desired width of the icon. This parameter only has an effect in Windows where icon resources can contain several icons of different sizes.
desiredHeight (int) – Specifies the desired height of the icon. This parameter only has an effect in Windows where icon resources can contain several icons
of different sizes.

4、There are three ways to create the ID numbers used by a widget:
1 Explicitly pass a positive integer into the constructor
2 Get wxPython to create IDs for you using the wx.NewId() function
3 Pass either the global constant wx.ID_ANY or -1 to
a widget constructor
