I want to recreate a grid. For example: old grid is 4x4, I want change it to 5x5.
Here is my code:
import wx
import wx.xrc
import wx.grid
class MyFrame2(wx.Frame):
def __init__(self, parent):
wx.Frame.__init__(self, parent, id=wx.ID_ANY, title=wx.EmptyString, pos=wx.DefaultPosition,
size=wx.Size(500, 300), style=wx.DEFAULT_FRAME_STYLE | wx.TAB_TRAVERSAL)
bSizer4 = wx.BoxSizer(wx.VERTICAL)
self.m_grid2 = wx.grid.Grid(self, wx.ID_ANY, wx.DefaultPosition, wx.DefaultSize, 0)
# Grid
self.m_grid2.CreateGrid(4, 4)
bSizer4.Add(self.m_grid2, 0, wx.ALL, 5)
self.m_button3 = wx.Button(self, wx.ID_ANY, u"MyButton", wx.DefaultPosition, wx.DefaultSize, 0)
bSizer4.Add(self.m_button3, 0, wx.ALL, 5)
self.m_button3.Bind(wx.EVT_BUTTON, self.OnClick)
self.SetSizer(bSizer4)
self.Layout()
def OnClick(self, event):
self.m_grid2.CreateGrid(5, 5)
self.Layout()
app = wx.App()
frame = MyFrame2(None)
frame.Show(True)
app.MainLoop()
It raise an error when I run that:
File "C:\Python27\lib\site-packages\wx-3.0-msw\wx\grid.py", line 1221, in CreateGrid
return _grid.Grid_CreateGrid(*args, **kwargs)
wx._core.PyAssertionError: C++ assertion "!m_created" failed at ..\..\src\generic\grid.cpp(2325) in wxGrid::CreateGrid(): wxGrid::CreateGrid or wxGrid::SetTable called more than once
It seems I can't recreate this grid again. How can do this job?
If you don't want to Append the rows and columns, then you'll just have to recreate the grid itself. Here's a fairly simple demo that demonstrates how to do that:

You may only call the CreateGrid function once. if you want to change the size, you need to use the functions AppendCols, AppendRows, DeleteCols or DeleteRows.
def OnClick(self, event):
self.m_grid2.AppendCols(1)
self.m_grid2.AppendRows(1)

I have two BoxSizers, the first one
sizer = wx.BoxSizer (wx.VERTICAL)
sizer.Add (self.grid2, 1, wx.EXPAND)
panel2.SetSizer (sizer)
and another vertical BoxSizers, to the left of the button grid, both BoxSizers interfere.
vbox1 = wx.FlexGridSizer (rows = 1, cols = 3, hgap = 5, vgap = 5)
buttonsBox1 = wx.BoxSizer (wx.VERTICAL)
buttonsBox1.Add (self.buttonoborved)
vbox1.Add (buttonsBox1)
vbox1.Add (self.grid2)
vbox1.Add (midPan1, wx.ID_ANY, wx.EXPAND | wx.ALL, 20)
panel2.SetSizer (vbox1)
An error occurs - Adding a window already in a sizer, detach it first!
How can they be called at the same time.
Edit:
That are two BoxSizer, one in other, but how can be put buttons in there.

It depends where you want to place the buttons but let's assume they should be at the bottom.

I am dynamically changing the number of wx objects in my GUI. The code is working but the alignment of the objects is not perfect. The static text objects are not middle aligned with the text objects.
Notice that the word 'if' is not perfectly aligned with 'field name'.

Please could someone advise on how I can fix this alignment issue.
Thanks a lot in advance!
Duh! It turns out I just needed to change the alignment when adding items to the row sizer.

I have a screen which has 6 grids as follows:
I'm adding a 7th grid.
This causes the screen to look like:
however I want the screen to be:
I tried to do it with flexgrid but it's not working.
This is my code:
sizer_2 = wx.BoxSizer(wx.HORIZONTAL)
sizer_2.AddSpacer(10)
sizer_4 = wx.BoxSizer(wx.VERTICAL)
sizer_4.Add(self.grid1, 1, wx.EXPAND, 0)

sizer_1.AddSpacer(20)
sizer_1.Add(sizer_3, 1, wx.EXPAND, 0)
self.SetSizer(sizer_1)

What can I do?
I don't like the grid sizers because I find them pretty confusing. So I typically take something like this and draw boxes around the various groups. The boxes represent BoxSizers. Once I have that done, I know what to do and write my code accordingly. Here's how I would lay this out:

for example now I want to add new panel with this event what can I do? and I want to create this panel with event.
I don't know if it is what you need but in this example you have:
panel with button and event
button call function in mainframe
mainframe add next panel (with grid) to boxsizer

I'm a newbie in wxpython and have been trying to put some widgets within books(treebook, notebook, choicebook) I have often ended up with some widgets placed inside containers not responding to events. I'm not sure what I'm doing wrong. Below is one of my code
import wx
class ChoicePanelTwo(wx.Panel):
def __init__(self, parent, seed):

self.SetBackgroundColour('blue')
sizer = wx.BoxSizer(wx.HORIZONTAL)

for i in range(seed):

self.SetBackgroundColour('green')
sizer = wx.BoxSizer(wx.HORIZONTAL)
self.RegisterList = wx.Choicebook(self, wx.ID_ANY)
sizer.Add(self.RegisterList, 1, wx.ALL|wx.EXPAND, 5)
for i in range(seed):
self.RegisterList.AddPage(ChoicePanelTwo(self, seed*50), str(i))

In this example. The choice book and list does seem to be working. What is that I'm doing wrong ?
It's a parenting issue. You are setting all the ChoicePanelOne instance's parents as the TreePanel when it should be the ChoicBook. And you're doing the same thing in ChoicePanelOne where you create a whole bunch of ChoicePanelTwo's whose parents are ChoicePanelOne when they should be RegisterList. Check out the slightly changed code below:
import wx
class ChoicePanelTwo(wx.Panel):
def __init__(self, parent, seed):
wx.Panel.__init__(self, parent=parent, id=wx.ID_ANY)
self.SetBackgroundColour('blue')
sizer = wx.BoxSizer(wx.HORIZONTAL)
self.List = wx.ListCtrl(self, -1, style=wx.LC_REPORT)
for i in range(seed):
self.List.InsertStringItem(i, str(i))

self.SetSizer(sizer)

You should download the wxPython demo as it has lots of good examples in it. Also see the wiki or my blog article.
You could use the Widget Inspection Tool to help you diagnose the problem as well as it will show you what parent is where and how your sizers are laid out, among other things.
