wx.griwx Float Editor fail when a cell value is None

hi to all

I have a problem with wx.Grid during data entry

I’ve set

self.grid.SetColFormatFloat(2, width=-1, precision=2)

and

self.grid.SetCellEditor(row, 2, gridlib.GridCellFloatEditor())

when I open the frame I’ve some cell values set to None

and in this cells I’ve to write something like 80.5 or 37.1

but when I start to write I can insert only a character like 8 or 3

when I pass on another cell and I return on the cell where I was inserting

I can insert, fynally my value 80.5 or 37.1

pratically if the value of the cell is None I can insert only a character

suggestions?

I attach a demo to reproduce the problem.

In the demo if you try to modify Azotemia, ALT and AST you can do it

but if you try to modify Glicemia or Urea you you don’t succeed in inserting more than a character

regards

I know that I should not do it but my browser refuse to load the demo so…

import wx

import wx.grid as gridlib

(2,‘UREA’,None,),

class MyForm(wx.Frame):

def init(self):

wx.Frame.init(self, parent=None, title=“Simple App”, size=(200,200))

panel = wx.Panel(self)

self.Bind(wx.EVT_CLOSE, self.OnExit)

self.grid = gridlib.Grid(panel, size=(400,200))

sizer = wx.BoxSizer(wx.VERTICAL)

sizer.Add(self.grid)

panel.SetSizer(sizer)

def OnCreateGrid(self,rs):

labels = [‘’,‘’, ‘result’, ]

lines = len(rs)

self.grid.CreateGrid(lines,len(labels))

for row in range(len(labels)):

self.grid.SetColLabelValue(row, labels[row])

test =

for i in rs:

test.append(i[1])

self.grid.SetRowLabelValue(row, test[row])

self.grid.SetColLabelSize(30)

self.grid.SetRowLabelSize(100)

self.grid.SetRowLabelAlignment(wx.ALIGN_LEFT,-1)

self.grid.SetColFormatFloat(2, width=-1, precision=2)

def OnOpen(self,):

self.OnCreateGrid(RS)

try:

for row,rec in enumerate(RS):

#print row

#print rec

for col,value in enumerate(rec):

self.grid.SetCellValue(row, col,“%s” % value )

self.grid.SetCellEditor(row, 2, gridlib.GridCellFloatEditor())

except:

pass

def OnExit(self,event):

self.Destroy()

if name == “main”:

app = wx.PySimpleApp()

frame = MyForm()

frame.OnOpen()

frame.Show()

app.MainLoop()

Fynally...the demo attached...

wx._core.PyAssertionError: C++ assertion "Assert failure" failed at /BUILD/wxPython-src-2.9.5.0.b20121231/src/generic/grideditors.cpp(910) in BeginEdit(): this cell doesn't have float value

The GridCellFloatEditor doesn't know how to deal with a "None" string value, which shouldn't be too surprising. You can use an empty string value for those cells instead.

Beppe,

If you plan on writing an electronic medical record using
wxPython you might want to take a look at GNUmed

Thanks I ve resolve using ifnull function in the query that retrive my recordset and now it works fine.Yes I am working with a research team that focused its efforts on the study of skin limphome writing an application like a lims and I know Gnumed that is inspiration for my work.
