i've made this code :
import wx
import List as li
from ChoiceBook import *
class MainTab(wx.Panel):
def __init__(self, parent, sb, dm):
wx.Panel.__init__(self, parent)
self.parent = parent
self.hardware = []
box = wx.StaticBox(self, wx.ID_ANY, "Appareil")
self.list = li.List(self, sb, dm)
sizerleft = wx.StaticBoxSizer(box,wx.HORIZONTAL)
sizerleft.Add(self.list, 1, wx.ALL|wx.EXPAND, 5)
box = wx.StaticBox(self, wx.ID_ANY, "Mesures")
self.notebook = Choicebook(self,dm)
sizerright = wx.StaticBoxSizer(box,wx.HORIZONTAL)
sizerright.Add(self.notebook, 1, wx.ALL|wx.EXPAND, 5)
sizer = wx.BoxSizer(wx.HORIZONTAL)
sizer.Add(sizerleft, 1, wx.ALL|wx.EXPAND, 5)
sizer.Add(sizerright, 1, wx.ALL|wx.EXPAND, 5)
self.SetSizer(sizer)
def update(self):
self.notebook.update()
it made this window, but when i resize it, it dosen't scale the contents. it just crop it, like this.
I think the probleme come from the StaticBox which are static i guess(i'm not sure).
I would like to know if it's possible to make it resize automatically?
or if not is there is another way to make a box whith a title like StaticBox and so make it resizable ?
EDIT: i figure it out with your help. in fact this wasn't this portion of cod fault but my list Class. i just remove all size in that file
before
wx.ListCtrl.__init__(self,
parent,
size=(800, -1),
style=wx.LC_REPORT | wx.LC_SINGLE_SEL)
self.rm = RM.Res_Man()
self.index = 0
self.InsertColumn(0, 'Appareil de mesure', width=125)
self.InsertColumn(1, 'Connecté')
self.InsertColumn(2, 'ID',width=300)
self.InsertColumn(3, 'Type',width=290)
self.sb = sb
after
wx.ListCtrl.__init__(self,
parent,
style=wx.LC_REPORT | wx.LC_SINGLE_SEL)
self.rm = RM.Res_Man()
self.index = 0
self.InsertColumn(0, 'Appareil de mesure')
self.InsertColumn(1, 'Connecté')
self.InsertColumn(2, 'ID')
self.InsertColumn(3, 'Type')
self.sb = sb
thanks you all ;)
I think that what you want, is to force it to Layout() on a RESIZE event.
However, remember that these items will have a minimum size.
Try this:
import wx
class MainTab(wx.Frame):
def __init__(self):
wx.Frame.__init__(self, None)
self.hardware = []
box = wx.StaticBox(self, wx.ID_ANY, "Appareil")
lc = wx.ListCtrl(self, wx.ID_ANY, style=wx.LC_REPORT|wx.LC_SINGLE_SEL|wx.LC_VRULES)
lc.InsertColumn(1, "Appareil de mesure")
lc.InsertColumn(2, "Connecte")
lc.InsertColumn(3, "ID")
lc.InsertColumn(4, "Type")
sizerleft = wx.StaticBoxSizer(box,wx.HORIZONTAL)
sizerleft.Add(lc, 1, wx.ALL|wx.EXPAND, 5)
box = wx.StaticBox(self, wx.ID_ANY, "Mesures")
cb = wx.Choicebook(self, wx.ID_ANY, pos=wx.DefaultPosition, size=wx.DefaultSize,
style=0, name="")
sizerright = wx.StaticBoxSizer(box,wx.HORIZONTAL)
sizerright.Add(cb, 1, wx.ALL|wx.EXPAND, 5)
sizer = wx.BoxSizer(wx.HORIZONTAL)
sizer.Add(sizerleft, 1, wx.ALL|wx.EXPAND, 5)
sizer.Add(sizerright, 1, wx.ALL|wx.EXPAND, 5)
self.SetSizer(sizer)
self.Bind(wx.EVT_SIZE, self.ReSize)
def ReSize(self,event):
self.Layout()
if __name__ == '__main__':
app = wx.App()
frame = MainTab()
frame.Show(True)
app.MainLoop()
I have had to hack it together as your code is in complete.

I have a problem: I want to make a password manager for myself .
I have the logic for the en/decoding done and also I have the dynamic adding of passwords done, but if I add too many passwords to my manager then I can't see all of the passwords because my screen is too small.
I wanted to add a scroll bar but the scroll bar didn't work.
Even after several hours of researching the code didn't want to work. This is the code for the PanelTwo:
class PanelTwo(wx.Panel):
#staticmethod
def scale_bitmap(bitmap, width, height):
image = wx.ImageFromBitmap(bitmap)
image = image.Scale(width, height, wx.IMAGE_QUALITY_HIGH)
result = wx.BitmapFromImage(image)
return result
def __init__(self, parent):
wx.Panel.__init__(self, parent=parent)
self.refr = wx.Button(self,wx.ID_ANY,u"Refresh")
self.refr.Bind(wx.EVT_BUTTON, self.refresh)
self.co = wx.Button(self, wx.ID_ANY, u"Close")
self.co.Bind(wx.EVT_BUTTON, self.close)
self.number_of_pwds = 0
self.frame = parent
self.mainSizer = wx.BoxSizer(wx.VERTICAL)
controlSizer = wx.BoxSizer(wx.HORIZONTAL)
self.widgetSizer = wx.BoxSizer(wx.VERTICAL)
#controlSizer.Add(self.Passest, 0, wx.CENTER | wx.ALL, 5)
controlSizer.Add(self.refr, 0, wx.CENTER | wx.ALL, 5)
controlSizer.Add(self.co, 0, wx.CENTER | wx.ALL, 5)
self.addButton = wx.Button(self, label="Add")
self.addButton.Bind(wx.EVT_BUTTON, self.onAddWidget)
controlSizer.Add(self.addButton, 0, wx.CENTER | wx.ALL, 5)
self.removeButton = wx.Button(self, label="Remove")
self.removeButton.Bind(wx.EVT_BUTTON, self.onRemoveWidget)
controlSizer.Add(self.removeButton, 0, wx.CENTER | wx.ALL, 5)
self.mainSizer.Add(controlSizer, 0, wx.CENTER)
self.mainSizer.Add(self.widgetSizer, 0, wx.CENTER | wx.ALL, 10)
self.SetSizer(self.mainSizer)
The adding and removing of the Pwds is here :
def onAddWidget(self, event):
self.number_of_pwds += 1
label = "Pwd %s" % self.number_of_pwds
name = "Pwd%s" % self.number_of_pwds
new_Text = wx.StaticText(self, label=label, name=name)
self.widgetSizer.Add(new_Text, 0, wx.ALL, 5)
self.frame.fSizer.Layout()
self.frame.Fit()
def onRemoveWidget(self, event):
if self.widgetSizer.GetChildren():
self.widgetSizer.Hide(self.number_of_pwds - 1)
self.widgetSizer.Remove(self.number_of_pwds - 1)
self.number_of_pwds -= 1
self.frame.fSizer.Layout()
self.frame.Fit()
my main Form is here :
class MyForm(wx.Frame):
def __init__(self):
wx.Frame.__init__(self, None, wx.ID_ANY,
"Passwort Manager",
size=(300,130))
self.panel_one = PanelOne(self)
self.panel_two = PanelTwo(self)
self.panel_three = PanelThree(self)
self.panel_two.Hide()
self.panel_three.Hide()
self.fSizer = wx.BoxSizer(wx.VERTICAL)
self.fSizer.Add(self.panel_one, 1, wx.EXPAND)
self.fSizer.Add(self.panel_two, 1, wx.EXPAND)
self.fSizer.Add(self.panel_three,1,wx.EXPAND)
self.SetSizer(self.fSizer)
self.SetBackgroundColour(Color.White)
def onSwitchPanels(self, event):
if self.panel_one.IsShown():
self.SetTitle("Passwort Manager")
self.SetBackgroundColour(Color.Random())
self.panel_one.Hide()
self.panel_two.Show()
elif self.panel_two.IsShown():
self.SetTitle("Passwort Manager")
self.SetBackgroundColour(Color.Random())
self.panel_three.Show()
self.panel_two.Hide()
else:
self.SetTitle("Passwort Manager")
self.SetBackgroundColour(Color.Random())
self.panel_one.Show()
self.panel_three.Hide()
self.Layout()
app = wx.App(False)
frame = MyForm()
frame.Show()
app.MainLoop()
So how can I add a dynamic scrollbar that resizes automatically and that works with my code? I am using Python3.6.
Thanks for helping me out.
Have you tried using a scrolled panel?

When I only hade one TxtCtrl, it's right side would expand all the way to the windows edge. But after I created a vertical BoxSizer to and added the horizontal one to that, the TxtCtrol only had a width of about 100 pixels. Why is this?
import wx
class MainPanel(wx.Panel):
def __init__(self, parent):
wx.Panel.__init__(self, parent, style=wx.SIMPLE_BORDER)
top_box = wx.BoxSizer(wx.VERTICAL)
box1 = wx.BoxSizer(wx.HORIZONTAL)

textureName = wx.TextCtrl(self, 1)
texturePath = wx.TextCtrl(self, 1)
box1.Add(wx.StaticText(self, 1, "Name: "), 0, wx.LEFT|wx.RIGHT|wx.TOP, 5)
box1.Add(textureName, 1, wx.ALIGN_LEFT|wx.RIGHT|wx.TOP, 5)

box2.Add(texturePath, 1, wx.ALIGN_LEFT|wx.RIGHT|wx.TOP, 5)
top_box.Add(box1)
top_box.Add(box2)
self.SetSizer(top_box)

title = "Exporter"
wx.Frame.__init__(self, parent, wx.ID_ANY, title,

self.panel = MainPanel(self)
self.Show()
if __name__ == "__main__":
app = wx.PySimpleApp()
frame = MainFrame(None, -1)
frame.Centre()
app.MainLoop()
pass
You need to use wx.EXPAND in the style.
top_box.Add(box1, 0, wx.EXPAND)
top_box.Add(box2)
From here: "When an item is Add'ed with the wxEXPAND flag, the item will be resized to fill its alloted area in the opposite orientation."
I'm having difficulty getting my sizers to work properly in wxpython. I am trying to do a simple one horizontal bar at top (with text in it) and two vertical boxes below (with gridsizers * the left one should only be 2 columns!! * inside each). I want the everything in the image to stretch and fit my panel as well (with the ability to add padding to sides and top/bottom).
I have two main issues:
1. I cant get the text in the horizontal bar to be in the middle (it goes to the left)
2. I would like to space the two vertical boxes to span AND fit the page appropriately (also would like the grids to span better too).
Here is my code (with some parts omitted):
self.LeagueInfoU = wx.Panel(self.LeagueInfo,-1, style=wx.BORDER_NONE)
self.LeagueInfoL = wx.Panel(self.LeagueInfo,-1, style=wx.BORDER_NONE)
self.LeagueInfoR = wx.Panel(self.LeagueInfo,-1, style=wx.BORDER_NONE)
vbox = wx.BoxSizer(wx.VERTICAL)
hbox1 = wx.BoxSizer(wx.HORIZONTAL)
hbox2 = wx.BoxSizer(wx.HORIZONTAL)
vbox2a = wx.GridSizer(12,2,0,0)
vbox3a = wx.GridSizer(10,3,0,0)
hbox1a = wx.BoxSizer(wx.VERTICAL)
vbox2 = wx.BoxSizer(wx.VERTICAL)
vbox3 = wx.BoxSizer(wx.VERTICAL)
hbox1.Add(self.LeagueInfoU, 1, wx.EXPAND | wx.ALL, 3)
vbox2.Add(self.LeagueInfoL, 1, wx.EXPAND | wx.ALL, 3)
vbox3.Add(self.LeagueInfoR, 1, wx.EXPAND | wx.ALL, 3)
vbox2a.AddMany([this is all correct])
self.LeagueInfoL.SetSizer(vbox2a)
vbox3a.AddMany([this is all correct])
self.LeagueInfoR.SetSizer(vbox3a)
font = wx.Font(20, wx.DEFAULT, wx.NORMAL, wx.BOLD)
self.Big_Header = wx.StaticText(self.LeagueInfoU, -1, 'Testing This')
self.Big_Header.SetFont(font)
hbox1a.Add(self.Big_Header, 0, wx.ALIGN_CENTER|wx.ALIGN_CENTER_VERTICAL)
self.LeagueInfoU.SetSizer(hbox1a)
hbox2.Add(vbox2, 0, wx.EXPAND)
hbox2.Add(vbox3, 0, wx.EXPAND)
vbox.Add(hbox1, 0, wx.EXPAND)
vbox.Add(hbox2, 1, wx.EXPAND)
self.LeagueInfo.SetSizer(vbox)
Is this what you're after?

To learn about spanning rows, I recommend looking at the wxPython demo. I think that may only be supported in wx.GridBagSizer and the FlexGridSizer though. You can try the span parameter though. Also, it should be noted that wx.GROW and wx.EXPAND are one and the same. You might also want to check out the wiki for more information: http://wiki.wxpython.org/GridBagSizerTutorial
I have written a small bit of code in wxpython in which the splitter window is used to split the dialog box and one panel has custom tree ctrl and the other has static box.
This code was working fine in Fedora and ubuntu, but in Windows the dialog box is appearing empty.
Main code:
wx.Dialog.__init__(self, None, 6, 'Filters',size = (500,600) )
self.splitter = wx.SplitterWindow(self, -1)
leftPanel = wx.Panel(self.splitter, -1)
leftBox = wx.BoxSizer(wx.VERTICAL)
self.__tree = TreeFilter(leftPanel, 1)
leftBox.Add(self.__tree, -1, wx.GROW)
self.__tree.Bind(CT.EVT_TREE_ITEM_CHECKED, self.checked)
leftPanel.SetSizer(leftBox)
rightPanel = wx.Panel(self.splitter, -1)
rightBox = wx.BoxSizer(wx.VERTICAL)
self.display = wx.StaticText(rightPanel, -1, '', style=wx.ALIGN_LEFT)
rightBox.Add(self.display, -1, wx.GROW)
btnsizer = wx.StdDialogButtonSizer()
btn = wx.Button(rightPanel, wx.ID_OK)
btn.SetDefault()
btnsizer.AddButton(btn)
btn = wx.Button(rightPanel, wx.ID_CANCEL)
btnsizer.AddButton(btn)
btnsizer.Realize()
rightBox.Add(btnsizer, 0, wx.ALIGN_CENTER_VERTICAL|wx.ALL, 5)
rightPanel.SetSizer(rightBox)
self.splitter.SplitVertically(leftPanel, rightPanel)
self.Centre()
where TreeFilter is a custom tree ctrl.
Please help me fixing the problem
The problem is that you don't have the splitter itself in a sizer that's set to expand. On my screen, you can see a little box all scrunched up in the left hand corner, so I knew something like that was happening.

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.
