You don’t set the size of the grid, so it’s just using the minimum amount of size necessary. If you want a more accurate size, you would be better off changing that line to
self.GetTopLevelParent().GetSize()
This will get you a lot closer to what you want. When I tried it, the grid was actually wider than the screen and had scrollbars. I personally prefer that to the white background. If you want, you could set the size of the frame and use that size for your grid as well.

Hi,
I try to place a wx.grid on a panel, and make its columns expand to parent, but I get a white space on the right side of cells:
I do:
import wx.grid as gridlib
class SidePanelGrid(gridlib.Grid):
def init(self, parent):
gridlib.Grid.init(self, parent, -1, name=“Side Panel Capacity Grid”)
self.CreateGrid(3,4)
self.HideRowLabels()
self.HideColLabels()
self.ShowScrollbars(wx.SHOW_SB_NEVER,wx.SHOW_SB_NEVER)
widt, heig = self.GetSize()
print "widt: ", widt
for row in xrange(3):
self.DisableRowResize(row)
for col in xrange(4):
self.SetCellAlignment(row, col, wx.ALIGN_CENTRE, wx.ALIGN_CENTRE)
for col in xrange(4):
self.SetColSize(col, (widt/4))
self.DisableColResize(col)
But I set the size of each column to 1/4 of grid size (there are 4 columns), so why is there whitespace on the right side of the cells?
self.SetColSize(col, (widt/4))

It doesn’t work. What do I do wrong above?

Because the grid is expanding, but the columns are not. The columns don’t expand when you change the size of your frame. If you want that to happen, you would have to catch EVT_SIZE and modify the grid’s column sizes yourself.

But the whitespace is there when I first start the application as well. I don’t resize the window manually.

wx.GROW is alias of wx.EXPAND, don’t know what happens if you use
both at the same time, don’t they negate each other?
wx.GROW

wx.EXPAND

Honestly, aren’t they teaching you kids Boolean algebra in high
school any more? “|” is the logical “or” operator. 1|1 == 1. In
fact, for any x, x|x == x.

Kids, not sure I qualify for that and no never had algebra but then I didn’t
do high school or the equivalent when I want to school back a little
while ago,
but I know I should one day maybe learn this stuff.

Hi Steve,
Well actually , Tim, "|" is the bitwise or operator; "or" is of course the
logical or operator.
