wxPython – 获取静态框的视觉属性

在本文中，我们将学习如何获得与静态框关联的 wx.VisualAttributes。为此，我们将使用静态 GetClassDefaultAttributes()函数。 GetClassDefaultAttributes()函数用于返回 wx.VisualAttributes 对象的背景色、前景色和字体等属性。

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

 

Parameter	Input Type	Description
variant	WindowVariant	variant associate with Static 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)
 
 
        # create static box
        self.sb = wx.StaticBox(pnl, 2, label ="Static Box",
                              pos =(20, 20), size =(100, 100))
 
        # wx.VisualAttributes object
        va = self.sb.GetClassDefaultAttributes(wx.WINDOW_VARIANT_NORMAL)
         
        # background and foreground colours
        print (va.colBg)
        print (va.colFg)
 
        # 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()
