Dear Sirs,
I’m trying to achive to set size of a grid cell, where the grid uses PyGridTableBase as datra source. I tried it on an example from the demo below, but I can’t set size (span cells acros multiple columns) in this grid. In the following example, when user right clicks on a cell, it is supposed to set size of cell on row 0 col 1 to 1 row and 4 columns (this cell will span over 4 columns), but it doesn’t work. What should I change below???
import wx
import wx.grid as gridlib

class HugeTable(gridlib.PyGridTableBase):
def __init__(self, log):
gridlib.PyGridTableBase.__init__(self)
self.log = log
self.odd=gridlib.GridCellAttr()
self.odd.SetBackgroundColour("sky blue")
self.even=gridlib.GridCellAttr()
self.even.SetBackgroundColour("sea green")
self.atts = {}
def GetAttr(self, row, col, kind):
#attr = [self.even, self.odd][row % 2]
attr = gridlib.GridCellAttr()
#print "sttr: ", attr
attr.IncRef()
self.atts[(row,col)] = attr
return self.atts[(row,col)]
def SetAttr(self,attr,row,col):
self.atts[(row,col)] = attr
# This is all it takes to make a custom data table to plug into a
