通过指定其以像素为单位测量的绝对坐标，可以将GUI小部件放置在容器窗口内。坐标相对于由其构造函数的size参数定义的窗口的尺寸。窗口小部件在窗口中的位置由其构造函数的pos参数定义。
import wx
app = wx.App()
window = wx.Frame(None, title = "wxPython Frame", size = (300,200))
panel = wx.Panel(window)
label = wx.StaticText(panel, label = "Hello World", pos = (100,50))
window.Show(True)
app.MainLoop()
但是，由于以下原因，此绝对定位不适合-
即使调整窗口大小，小部件的位置也不会改变。
在具有不同分辨率的不同显示设备上，外观可能不一致。
布局修改很困难，因为可能需要重新设计整个表单。
wxPython API提供了Layout类，以便更优雅地管理容器内小部件的位置。布局管理器相对于绝对定位的优势是-
布局管理器在wxPython中称为Sizer。 Wx.Sizer是所有sizer子类的基类。让我们讨论一些重要的大小调整器，例如wx.BoxSizer，wx.StaticBoxSizer，wx.GridSizer，wx.FlexGridSizer和wx.GridBagSizer。
| S.N. | Sizers & Description |
|---|---|
| 1 | BoxSizer
This sizer allows the controls to be arranged in row-wise or column-wise manner. BoxSizer’s layout is determined by its orientation argument (either wxVERTICAL or wxHORIZONTAL). |
| 2 | GridSizer
As the name suggests, a GridSizer object presents a two dimensional grid. Controls are added in the grid slot in the left-to-right and top-to-bottom order. |
| 3 | FlexiGridSizer
This sizer also has a two dimensional grid. However, it provides little more flexibility in laying out the controls in the cells. |
| 4 | GridBagSizer
GridBagSizer is a versatile sizer. It offers more enhancements than FlexiGridSizer. Child widget can be added to a specific cell within the grid. |
| 5 | StaticBoxSizer
A StaticBoxSizer puts a box sizer into a static box. It provides a border around the box along with a label at the top. |
