wxPython - 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. Following steps are involved in preparing a statcboxsizer −

• Create a wx.StaticBox object.
• Declare a wx.StaticBoxSizer with the above static box as its argument.
• Create the controls and add in staticbox sizer.
• Set it as the sizer for the frame.

Example

In the following example, two staticbox sizers are created and added into a top vertical box sizer, which controls the layout of the panel inside a frame.

The first staticbox sizer is created around a static box named ‘Name’.

nm = wx.StaticBox(panel, -1, 'Name:') 
nmSizer = wx.StaticBoxSizer(nm, wx.VERTICAL)

A Horizontal box sizer, holding two labels and two text boxes, is added into nmSizer static box sizer.

nmbox = wx.BoxSizer(wx.HORIZONTAL)
  
fn = wx.StaticText(panel, -1, "First Name") 
nmbox.Add(fn, 0, wx.ALL|wx.CENTER, 5) 
nm1 = wx.TextCtrl(panel, -1, style = wx.ALIGN_LEFT) 
nm2 = wx.TextCtrl(panel, -1, style = wx.ALIGN_LEFT) 
ln = wx.StaticText(panel, -1, "Last Name") 
         
nmbox.Add(nm1, 0, wx.ALL|wx.CENTER, 5) 
nmbox.Add(ln, 0, wx.ALL|wx.CENTER, 5) 
nmbox.Add(nm2, 0, wx.ALL|wx.CENTER, 5)
  
nmSizer.Add(nmbox, 0, wx.ALL|wx.CENTER, 10)

Similarly, another staticbox sizer holds a static box named ‘Buttons’.

sbox = wx.StaticBox(panel, -1, 'buttons:') 
sboxSizer = wx.StaticBoxSizer(sbox, wx.VERTICAL)

Two button objects, named ‘ok’ and ‘cancel’ are put in a horizontal box sizer, which in turn, is placed inside the second staticbox sizer.

hbox = wx.BoxSizer(wx.HORIZONTAL) 
okButton = wx.Button(panel, -1, 'ok') 

hbox.Add(okButton, 0, wx.ALL|wx.LEFT, 10) 
cancelButton = wx.Button(panel, -1, 'cancel') 

hbox.Add(cancelButton, 0, wx.ALL|wx.LEFT, 10) 
sboxSizer.Add(hbox, 0, wx.ALL|wx.LEFT, 10)

Two static box sizers, ‘name’ and ‘Buttons’ are added into a vertical box sizer acting as the layout manager of the panel in the top level frame.

panel = wx.Panel(self) 
vbox = wx.BoxSizer(wx.VERTICAL)
  
vbox.Add(nmSizer,0, wx.ALL|wx.CENTER, 5) 
vbox.Add(sboxSizer,0, wx.ALL|wx.CENTER, 5) 
panel.SetSizer(vbox)

Following is the complete code −

import wx 
 
class Mywin(wx.Frame): 
   def __init__(self, parent, title): 
      super(Mywin, self).__init__(parent, title = title)
		
      panel = wx.Panel(self) 
      vbox = wx.BoxSizer(wx.VERTICAL) 
      nm = wx.StaticBox(panel, -1, 'Name:') 
      nmSizer = wx.StaticBoxSizer(nm, wx.VERTICAL) 
       
      nmbox = wx.BoxSizer(wx.HORIZONTAL) 
      fn = wx.StaticText(panel, -1, "First Name") 
		
      nmbox.Add(fn, 0, wx.ALL|wx.CENTER, 5) 
      nm1 = wx.TextCtrl(panel, -1, style = wx.ALIGN_LEFT) 
      nm2 = wx.TextCtrl(panel, -1, style = wx.ALIGN_LEFT) 
      ln = wx.StaticText(panel, -1, "Last Name") 
         
      nmbox.Add(nm1, 0, wx.ALL|wx.CENTER, 5)
      nmbox.Add(ln, 0, wx.ALL|wx.CENTER, 5) 
      nmbox.Add(nm2, 0, wx.ALL|wx.CENTER, 5) 
      nmSizer.Add(nmbox, 0, wx.ALL|wx.CENTER, 10)  
		
      sbox = wx.StaticBox(panel, -1, 'buttons:') 
      sboxSizer = wx.StaticBoxSizer(sbox, wx.VERTICAL) 
		
      hbox = wx.BoxSizer(wx.HORIZONTAL) 
      okButton = wx.Button(panel, -1, 'ok') 
		
      hbox.Add(okButton, 0, wx.ALL|wx.LEFT, 10) 
      cancelButton = wx.Button(panel, -1, 'cancel') 
		
      hbox.Add(cancelButton, 0, wx.ALL|wx.LEFT, 10) 
      sboxSizer.Add(hbox, 0, wx.ALL|wx.LEFT, 10) 
      vbox.Add(nmSizer,0, wx.ALL|wx.CENTER, 5) 
      vbox.Add(sboxSizer,0, wx.ALL|wx.CENTER, 5) 
      panel.SetSizer(vbox) 
      self.Centre() 
         
      panel.Fit() 
      self.Show()  
		
app = wx.App() 
Mywin(None,  'staticboxsizer demo') 
app.MainLoop()

The above code produces the following output −
