I am trying to make a telemetry software for a college project, that's why I'm using wxPython to make a GUI. I'm currently trying to make a function that displays a graph of brake_p and throttle in function of the time after I opened the entry file.
The code looks good to me, however it looks like there is an error inside the module that blocks me from succeeding.
Here is the error I get when I open the entry file :

The error I can't understand is the part in bold caracters,as it is nowhere in my code :
Drawgraphics.logScale = self.logScale
AttributeError: 'method' object has no attribute 'logScale'
I 'd like to add I plan to add a bar marker on the graph that would be either automatically move at real-time, or either movable by the user so the time at the marker would be used to display in other widget data corresponding to the exact instant (like in the matlab simulink graph/scopes), which means I can't store the graph as a bitmap but really as a graph/plot.
I tried to switch to another library to import the plot into the wxFrame but I just can't make it work as they look more complicated to me, so I got back to this method.
Here is the code :

And here is a link to the example data file : data file
I'm trying to set-up a display to show the gamertag and avatar of users added to a text file, it most of the way there but I can't get them to position properly.
A quick mock-up of what I want: here.
Here is what I currently have on start: here
EDIT: I've switched from using a BoxSizer to using a GridSizer and that seems to have fixed the position issue, they no longer overlap, the shifting problem is still present however.
The sizer containing the users shouldn't be overlapping with the input sizer at the top, I don't know what is causing this.
And what happens when it updates to check for new users: here
Might not be that easy to see but in the second image the lowest user is shifted down, it gets further and further down as the program runs, each time it is moved down by it's own height.
The relevant code areas:
Creating the starting sizers
self.main_sizer = wx.BoxSizer(wx.VERTICAL)
self.widget_sizer = wx.BoxSizer(wx.VERTICAL)
#Holds input for gamertags and addition
self.input_sizer = wx.BoxSizer(wx.HORIZONTAL)
#Content to be added immediately.
self.gamer_tag_textbox = wx.TextCtrl(self, -1)
self.gamer_tag_textbox.SetFocus()
self.add_gamer_tag = wx.Button(self, -1, 'Add Friend')
#Contains the displayed content
self.user_sizer = wx.BoxSizer(wx.VERTICAL)
#Add objects to sizers
self.input_sizer.Add(self.gamer_tag_textbox, 0)
self.input_sizer.Add(self.add_gamer_tag, 0)
#Set up the sizers
self.widget_sizer.Add(self.input_sizer, 0)
self.widget_sizer.Add(self.user_sizer, 0)
self.main_sizer.Add(self.widget_sizer, 0)
self.SetSizer(self.main_sizer)
Adding sizers created for each user to the main user_sizer.
def display_user_content(self, details):
self.user_sizer.Clear(True)
#This is different to the original code, it originally used boxsizers in the for each loop.
self.single_user_sizer = wx.GridSizer(cols=2)
for each in details:
#Create sizer to contain user information
#Get username
username = each[0]
#Get location of image file
location = each[-1]
#Create static text to contain username
stat = wx.StaticText(self, -1, 'username')
#Load image from location and convert to bitmap.
png = wx.Image(location, wx.BITMAP_TYPE_ANY).ConvertToBitmap()
#Create bitmap
avatar = wx.StaticBitmap(self, -1, png)
#Add to sizer
self.single_user_sizer.Add(avatar, 1)
self.single_user_sizer.Add(stat, 1)
#Add each users sizer to main user sizer
self.user_sizer.Add(self.single_user_sizer, 1)
#Add main user sizer to widget sizer
self.widget_sizer.Add(self.user_sizer, 0)

At the end of the display_user_content function I was adding the user_sizer to the widget_sizer each time, this was unnecessary and was causing a doubling of the number of results, I have removed that line and my code now works.
The fixed code:

self.user_sizer.Clear(True)
self.single_user_sizer = wx.GridSizer(cols=2, hgap=5, vgap=5)
for each in details:
#Get username
self.username_sizer = wx.BoxSizer(wx.HORIZONTAL)
username = each[0]
#Get location of image file
location = each[-1]
#Create static text to contain username
stat = wx.StaticText(self, -1, 'username')
#Load image from location and convert to bitmap.
png = wx.Image(location, wx.BITMAP_TYPE_ANY).ConvertToBitmap()
#Create bitmap
avatar = wx.StaticBitmap(self, -1, png)
#Add to sizer
self.single_user_sizer.Add(avatar, 0)
self.username_sizer.Add(stat, 0)
self.single_user_sizer.Add(self.username_sizer, 0)
#Add each users sizer to main user sizer
self.user_sizer.Add(self.single_user_sizer, 0)
#Add main user sizer to widget sizer
#self.widget_sizer.Add(self.user_sizer, 0)
self.Fit()
I am trying to make a "table" look good within my panel. This issue I'm having is that the table fills up the panel but everything is to the left. I would like to have each column be the same size and span the entire width of the panel. I have seen the ListCtrlAutoWidthMixin but am not sure how I could utilize this. Here is what I have in code:
self.Analysis = scrolled.ScrolledPanel(self.Notebook3, -1)
# Set Up Analysis Page (Page has four panels -- I care about Top left one)
self.AnalysisUL = wx.Panel(self.Analysis,-1, style=wx.BORDER_NONE)
self.AnalysisUR = wx.Panel(self.Analysis,-1, style=wx.BORDER_NONE)
self.AnalysisLL = wx.Panel(self.Analysis,-1, style=wx.BORDER_NONE)
self.AnalysisLR = wx.Panel(self.Analysis,-1, style=wx.BORDER_NONE)
# Top Left Box (Analyze Button and Projected Points Total)
self.Picks_Left = wx.ListCtrl(self.AnalysisUL,-1,style=wx.LC_REPORT | wx.BORDER_NONE)
self.Picks_Left.InsertColumn(1,'col1')
self.Picks_Left.InsertColumn(2,'col2',format=wx.LIST_FORMAT_CENTRE)
self.Picks_Left.InsertColumn(3,'col3',format=wx.LIST_FORMAT_CENTRE)
self.Picks_Left.InsertColumn(4,'col4',format=wx.LIST_FORMAT_CENTRE)
self.Picks_Left.SetColumnWidth(0,-2)
self.Picks_Left.SetColumnWidth(1,-2)
self.Picks_Left.SetColumnWidth(2,-2)
self.Picks_Left.SetColumnWidth(3,-2)
# Sizer
vbox_UL = wx.BoxSizer(wx.VERTICAL)
#Title for Table
fontUL = wx.Font(14, wx.DEFAULT, wx.NORMAL, wx.BOLD)
self.UL_text = wx.StaticText(self.AnalysisUL, -1, 'Title')
self.UL_text.SetFont(fontUL)
vbox_UL.Add(self.UL_text, 0, wx.CENTER|wx.ALL,20)
vbox_UL.Add(self.Picks_Left,1,wx.EXPAND|wx.ALL,3)
self.AnalysisUL.SetSizer(vbox_UL)
Again, the table spans the panel, but all my columns are shifted to the left. Also, I do not want to set the column size manually (unless I can grab the panel size and then divide by the number of columns I have -- since the program will be used on computers with different resolutions). I have tried this approach but cannot seem to get the correct size of the panels. The numbers I get with GetSize() and GetClientSize() are all too small.
Thanks for any help!

I think the trouble with the GetSize() approach might have been that you were calling it before the effects of the sizer took place, so it was returning the original size of the ListCtrl before the sizer resized it to fit the panel. Try this code after the last line of your code:
table_width = self.Picks_Left.GetSize()[0] #GetSize returns (width, height) tuple
num_col = self.Picks_Left.GetColumnCount()
col_width = table_width/num_col
for i in range(0, num_col):
self.Picks_Left.SetColumnWidth(i, col_width)
You should use the RowColSizer, which is quite fit for your request. Here is a small demo how to use it:
import wx
import wx.lib.rcsizer as rcs
class TestPanel(wx.Panel):
def __init__(self, parent):
wx.Panel.__init__(self, parent, -1)
sizer = rcs.RowColSizer()
text = "This sizer lays out it's items by row and column "\
"that are specified explicitly when the item is \n"\
"added to the sizer. Grid cells with nothing in "\
"them are supported and column- or row-spanning is \n"\
"handled as well. Growable rows and columns are "\
"specified just like the wxFlexGridSizer."
sizer.Add(wx.StaticText(self, -1, text), row=1, col=1, colspan=5)
sizer.Add(wx.TextCtrl(self, -1, "(3,1)"), flag=wx.EXPAND, row=3, col=1)
sizer.Add(wx.TextCtrl(self, -1, "(3,2)"), row=3, col=2)
sizer.Add(wx.TextCtrl(self, -1, "(3,3)"), row=3, col=3)
sizer.Add(wx.TextCtrl(self, -1, "(3,4)"), row=3, col=4)
sizer.Add(
wx.TextCtrl(self, -1, "(4,2) span:(2,2)"),
flag=wx.EXPAND, row=4, col=2, rowspan=2, colspan=2
)
sizer.Add(wx.TextCtrl(self, -1, "(6,4)"), row=6, col=4)
sizer.Add(wx.TextCtrl(self, -1, "(7,2)"), row=7, col=2)
sizer.Add(wx.TextCtrl(self, -1, "(8,3)"), row=8, col=3)
sizer.Add(
wx.TextCtrl(self, -1, "(10,1) colspan: 4"),
flag=wx.EXPAND, pos=(10,1), colspan=4
)
sizer.Add(
wx.TextCtrl(self, -1, "(3,5) rowspan: 8, growable col", style=wx.TE_MULTILINE),
flag=wx.EXPAND, pos=(3,5), size=(8,1)
)
box = wx.BoxSizer(wx.VERTICAL)
box.Add(wx.Button(self, -1, "A vertical box"), flag=wx.EXPAND)
box.Add(wx.Button(self, -1, "sizer put in the"), flag=wx.EXPAND)
box.Add(wx.Button(self, -1, "RowColSizer at (12,1)"), flag=wx.EXPAND)
sizer.Add(box, pos=(12,1))
sizer.Add(
wx.TextCtrl(self, -1, "(12,2) align bottom"),
flag=wx.ALIGN_BOTTOM, pos=(12,2)
)
sizer.Add(
wx.TextCtrl(self, -1, "(12,3) align center"),
flag=wx.ALIGN_CENTER_VERTICAL, pos=(12,3)
)
sizer.Add(wx.TextCtrl(self, -1, "(12,4)"),pos=(12,4))
sizer.Add(
wx.TextCtrl(self, -1, "(12,5) full border"),
flag=wx.EXPAND|wx.ALL, border=15, pos=(12,5)
)
sizer.AddGrowableCol(5)
sizer.AddGrowableRow(9)
sizer.AddSpacer(10,10, pos=(1,6))
sizer.AddSpacer(10,10, pos=(13,1))
self.SetSizer(sizer)
self.SetAutoLayout(True)
app = wx.App()
frame = wx.Frame(None, -1)
pn = TestPanel(frame)
frame.Show()
frame.Maximize()
app.MainLoop()
The same request also could be achieved by a more fancy way use the aui
Hope it helps you out.
Is there any way of implementing padding in the top and bottom of my program for 3 and 4?
Or is there a workaround like adding \n etc....
I feel asif the line numbers and the Styled text are too close to the top and bottom.
How about using panels of the same color nested inside the sizer as a dirty workaround?

self.panel_top.SetBackgroundColour(wx.BLACK)
self.panel_bottom = wx.Panel(self.panel, size = (20, -1))

sizer = wx.BoxSizer(wx.VERTICAL)
sizer.Add(self.panel_top, 0, wx.EXPAND,border=20)
sizer.Add(self.text, 1, wx.EXPAND,border=20)
sizer.Add(self.panel_bottom, 0, wx.EXPAND,border=20)
self.panel.SetSizer(sizer)
No, I don't think that Scintilla has a property that controls the size of the top and bottom margins.
i am having an interesting problem,
This program is a simple image viewer and it can contain different images in a listbox. The listbox contains the names of the images. You can load an image to an item in the listbox. You can click any item on the listbox to see its image. For some reason Destroy() is not functioning properly. Please run the following code if you are unable to understand me,

Try this to see what the error is,
1.you press create new (any amount of times)
2.press, load file
3. click any item on the listbox (except for the one that you are in)
4. Then go back to the orginal item that you were in,
5. Then click any item, other than the one you are currently in
There will be some sort of problem, the image does not destroy itself and returns an error like the following:
(, PyDeadObjectError('The C++ part of the StaticBitmap object has been deleted, attribute access no longer allowed.',), )
I am still able to load images but the previous images do not delete.
It is hard to word this problem, if anyone can help me with this situation, it would be greatly appreciated. If you need further explanation please comment. I thank you greatly for viewing.
Here you have your code fixed to clear your current image when loading another one.
This is done basically using self.parent.bitmap.Destroy().
I modified some few things without changing the structure of your code, in order for you to recognize changes. I eliminated globals calls. Look how I also eliminated the global IMAGE_LISTSEL variable and converted it in a class attribute. That is what Robin and Fenikso were telling you. Try to do the same with IMAGE_NAME and IMAGE_DATA.
Although the code is working, it is still far from being acceptable wxpython code. You can get many examples of correctly written wxpython code in the web. If you can afford it I recommend to you wxPython in Action from Noel Rappin and Robin Dunn.

Sometimes you are using bmp1 and bitmap1 as local variables and sometimes as globals. Since you are making multiple instances of them without saving the prior references anywhere then you are losing your references to the already existing objects. When you Destroy() them then you are only destroying the most recently created instances.
Try adding them to some sort of collection (like a list) instead and then you can access any of the items from the list when you need them later. Also try to avoid using global variables. Store your variables in the object instances that they belong to.
