wxPython |获取单选框的默认属性

在本文中，我们将学习与 wxPython 的 wx.RadioBox 类关联的 GetClassDefaultAttributes()函数。 GetClassDefaultAttributes()函数用于返回 wx.VisualAttributes 对象，以获取与单选框关联的背景颜色、前景色和字体等属性。
它将变体作为参数参数。

Syntax: wx.RadioBox.GetClassDefaultAttributes(variant=WINDOW_VARIANT_NORMAL)
Parameters:

Parameter	Input Type	Description
variant	WindowVariant	Variant for Radio Box.

Return Type: wx.VisualAttributes

代码示例：

Python3

import wx
 
 
class FrameUI(wx.Frame):
 
    def __init__(self, parent, title):
        super(FrameUI, self).__init__(parent, title = title, size =(300, 200))
 
        # function for in-frame components
        self.InitUI()
 
    def InitUI(self):
        # parent panel for radio box
        pnl = wx.Panel(self)
 
        # list of choices
        lblList = ['Radio One', 'Radio Two']
 
        # create radio boc containing above list
        self.rbox = wx.RadioBox(pnl, label ='RadioBox', pos =(80, 10), choices = lblList,
                                majorDimension = 1, style = wx.RA_SPECIFY_COLS)
 
        # create wx.VisualAttributes object
        vb = self.rbox.GetClassDefaultAttributes()
 
        # print Background Colour
        print (vb.colBg)
 
        # print Foreground Colour
        print (vb.colFg)
 
        # print Background Colour
        print (vb.font)
 
        # set frame in centre
        self.Centre()
        # set size of frame
        self.SetSize((400, 250))
        # show output frame
        self.Show(True)
 
 
# wx App instance
ex = wx.App()
# Example instance
FrameUI(None, 'RadioButton and RadioBox')
ex.MainLoop()
