Wxpython Notes (i)

Frame is a framework that can be directly understood as a window. To create a subclass of a frame, you need to call the constructor of the frame class, with the following prototype:

Wx. Frame (parent, Id=-1, title= "", pos=wx. Defaultposition, Size=wx. DefaultSize, Style=wx. Default_frame_style, name= "FRAME")

The meaning of each parameter:

Parent: The top-level window uses none directly.

ID: identification, there are three ways to assign: 1, you specify a positive number, but to ensure that the same form can not be repeated, 2, the value of 1 or Wx.id_any, is automatically assigned by the system, you can pass frame. GetId () to obtain this value; 3, use WX. NewId () function to create the.

POS: Window position.

Size: Window sizes.

Style: Styles, wherein, WX. The value of Default_frame_style is: Wx.maximize_box | Wx. Minimize_box | Wx.   Resize_border | Wx. System_menu | Wx. CAPTION | Wx. Close_box

Add a style using "|", remove a style using "^"

Use of Wxpython

1) Create an Application object
App = WX. APP ()

2) Access to application management
App. Mainloop ()

3) Create window Window–frame
Win = WX. Frame (None)
Or
Win = WX. Frame (None, title= "Simple Editor")


4) display window:
Win. Show ()

Eg: a program with only one window
#!/usr/bin/python
#encoding =utf-8

Import WX
App=wx. APP () #创建应用程序对象
Win=wx. Frame (None)
Win. Show ()

App. Mainloop () #进入程序管理



5) Add components to the window
The format is:
BTN = wx. Button (Win)

A. Set the title, label information for the component.
The format is:
Loadbutton = wx. Button (Win, label= ' Open ')

B. Set the location (POS) for the component, size (size)

6) Add Component---text box
A. Default text box: Text control:wx. Textctrl
B. Set to Text area: Style=wx.te_multiline |wx. HScroll
#!/usr/bin/python
#encoding =utf-8

Import WX
App=wx. APP () #创建应用程序对象
Win=wx. Frame (none,title= "My Program", Size= (410,335))

Fbutton=wx. Button (win,label= "Open", pos= (225,5), size= (80,25))
Sbutton=wx. Button (win,label= "Save", pos= (315,5), size= (80,25))
Filename=wx. Textctrl (win,pos= (5,5), size= (210,25))
Content=wx. Textctrl (win,pos= (5,35), size= (390,260), style=wx.te_multiline| WX. HScroll) #wx. Te_multiline to get multiple lines of text (with vertical scroll bars by default) and Wx.hscroll to get horizontal scroll bars
Win. Show ()

App. Mainloop () #进入程序管理
