Auto-size panel to fit grid?

Hello,

I’m trying to write a simple grid function. Please see code below. My question is: is there a way to let the panel to auto-size itself to fit the grid so that user does not need to drag to frame to see all the cells?

Thanks for your help!

import wx import wx.grid

class GridBaseResult(object):
def init(self):
self.value = None

class GridBaseFrame(wx.Frame):
def init(self, lst, data, title, rowLabels = None, colLabels = None,

             msg = "", hAlign = wx.ALIGN_CENTRE, vAlign = wx.ALIGN_CENTRE):
    wx.Frame.__init__(self, None, -1, title, pos = (300, 200))
    panel = wx.Panel(self) 
    self.data = data

    msgLbl = wx.StaticText(panel, -1, msg)
    topSizer = wx.BoxSizer(wx.HORIZONTAL)
    topSizer.Add (msgLbl,0)
   
    self.okBtn = wx.Button(panel, -1, "Ok")
    self.cancelBtn = wx.Button(panel, -1, "Cancel")
    btnSizer = wx.BoxSizer(wx.VERTICAL)
    btnSizer.Add(self.okBtn, 0)
    btnSizer.Add((10,10), 0)
    btnSizer.Add(self.cancelBtn, 0)

    self.Bind(wx.EVT_BUTTON, self.OnOkClick, self.okBtn)
    self.Bind(wx.EVT_BUTTON , self.OnCancelClick, self.cancelBtn)
                           
    cntRow = len(lst)
    cntCol = len(lst[0])                       
    self.grid = wx.grid.Grid(panel)
    self.grid.CreateGrid(cntRow,cntCol)

    botSizer = wx.BoxSizer(wx.HORIZONTAL)
    botSizer.Add (self.grid, 1, wx.GROW|wx.ALL, 10)
    botSizer.Add

(btnSizer, 0, wx.EXPAND|wx.ALL, 10)

    mainSizer = wx.BoxSizer (wx.VERTICAL)
    mainSizer.Add(topSizer, 0, wx.GROW|wx.ALL, 10)
    mainSizer.Add(botSizer, 1, wx.EXPAND|wx.ALL, 10)
    panel.SetSizer

(mainSizer)
mainSizer.Fit (self)
mainSizer.SetSizeHints(self)

    if rowLabels:         
        for row in range(cntRow):
            self.grid.SetRowLabelValue(row, rowLabels[row])

    if colLabels:
        for col in range(cntCol):       
            self.grid.SetColLabelValue(col, colLabels[col])
    for row in range(cntRow):      
        for col in range(cntCol):

            self.grid.SetCellValue(row, col, lst[row][col])
            self.grid.SetCellAlignment(row, col, hAlign, vAlign)               

def OnOkClick(self, event):
     self.data.value

= self.GetGridValues(self.grid)
self.Destroy()

def OnCancelClick(self, event):
    self.data.value = None
    self.Destroy()

def GetGridValues (self, grid):
    cntRow = grid.GetNumberRows()
    cntCol = grid.GetNumberCols()
    lst = [[]]*cntRow
    for row in range(cntRow):
        for col in range(cntCol):
            lst[row].append(grid.GetCellValue

(row,col))
return lst

def GridBase (title, lst, rowLabels = None, colLabels = None,

app = wx.PySimpleApp
()
data = GridBaseResult()
GridBaseFrame(lst, data, title, rowLabels, colLabels, msg, hAlign, vAlign).Show()
app.MainLoop()
return data.value

def _Test_GridBase():

colLabels = ['col1', 'col2', 'col3']
msg = "Edit data in grid"

print lst
