I'm learning wxPython and I'm having an issue. Here is my code below. It doesn't really work. What I'm trying to do is get a button in the top left section below the text area that says "Enter Task". I want the text input area and "enter task" button to be in a column so that the combined height of the two equals the height of the Start and Exit buttons next to them. Any help? Sizers confuse me.

I don't really know where your problem is. In my opinion all of the parts where already there, you just have to put them together. If I understood what you wanted, just replace the text field by a panel containing the text field and a button with a vertical sizer. Nice typing exercise, let me suggest a solution:

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?
import wx
import wx.lib.scrolledpanel as scrolled
class TestPanel(scrolled.ScrolledPanel):
def __init__(self, parent):
scrolled.ScrolledPanel.__init__(self, parent, -1)
"""
Write your code here...
"""
self.SetupScrolling()
I have a simply code:
import wx
class Glowne(wx.Panel):
def __init__(self, parent):
wx.Panel.__init__(self, parent=parent)
pos = 55
tekst = 'HELLO - position'
font = wx.Font(18, wx.DEFAULT, wx.NORMAL, wx.NORMAL)
wx.StaticText(self, -1, tekst, (300, pos)).SetFont(font)
btn = wx.Button(self, -1, "Change pos", (345, 100))
#self.Bind(wx.EVT_BUTTON, Program.zmiana, btn)
class Program(wx.Frame):
def __init__(self):
wx.Frame.__init__(self, None, wx.ID_ANY,'Program')
panel_one = Glowne(self)
self.SetSize((800,600))
self.Centre()
if __name__ == "__main__":
app = wx.App(False)
frame = Program()
frame.Show()
app.MainLoop()
How can I modyfy pos variable after hitting "Change pos" button?
In my real program I have something like:
name
name1
name2
"BUTTTON"
I would like to add wx.TextCtrl method between name2 and button after hitting "BUTTON". I need to modyfy a frame (add place beetwen name2 and button). I do not know how can I achieve that.
EDIT. There is a code I need to modify:
def __init__(self, parent):
global odstep
self.panel = wx.Panel.__init__(self, parent)
odstep = 0
odstep1 = 0
font = wx.Font(13, wx.DEFAULT, wx.NORMAL, wx.NORMAL)
for name in config['rewir1']:
nazwa_zliczana = config['rewir1'][name]
odstep += 22
self.name1 = wx.StaticText(self, -1, name, (300, 10 + odstep))
self.name1.SetFont(font)
btn_usuwanie = wx.Button(self, -1, u"Usuń", (475, 10 + odstep))
self.Bind(wx.EVT_BUTTON, lambda evt, i: Program.Usuwanie(evt, i), btn_usuwanie)
wx.StaticText(self, -1, 'PART I', (365, 0), style=wx.ALIGN_CENTER).SetFont(font)
odstep1 = odstep + 50
print odstep
for name in config['rewir2']:
nazwa_zliczana = config['rewir2'][name]
odstep1 += 22
self.name2 = wx.StaticText(self, -1, name, (300, 50 + odstep1))
self.name2.SetFont(font)
btn_usuwanie_2 = wx.Button(self, -1, u"Usuń", (475, 50 + odstep1))
self.Bind(wx.EVT_BUTTON, lambda evt, i: Program.Usuwanie(evt, i), btn_usuwanie_2)
print odstep1
wx.StaticText(self, -1, 'PART II', (365, 80 + odstep), style=wx.ALIGN_CENTER).SetFont(font)
self.btn = wx.Button(self, -1, "Change panel", (345, 500))
self.btn_dodaj_rewir1 = wx.Button(self, -1, "Add name", (345, 42 + odstep))
self.btn_dodaj_rewir2 = wx.Button(self, -1, "Add name", (345, 84 + odstep1))
self.Bind(wx.EVT_BUTTON, self.new_name, self.btn_dodaj_rewir1)
You need to save wx.StaticText instanced. To change property of it later.
Use SetPosition method to change position.
Bind EVT_BUTTON event to event handler (change_pos in the following code).
class Glowne(wx.Panel):
def __init__(self, parent):
wx.Panel.__init__(self, parent=parent)
tekst = 'HELLO - position'
font = wx.Font(18, wx.DEFAULT, wx.NORMAL, wx.NORMAL)
self.text = wx.StaticText(self, -1, tekst, (300, 55)) # Save for later use
self.text.SetFont(font)
btn = wx.Button(self, -1, "Change pos", (345, 100))
btn.Bind(wx.EVT_BUTTON, self.change_pos)
def change_pos(self, event):
x, y = self.text.Position
self.text.SetPosition((x, y + 10))
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.
Here's an example that works for me:

I have a listbox,
How can I change the string of current selected item of the listbox to another string?
I cant really find how to do this on Google.
Just delete selected string and insert a new one, like it is done in this example for a single-choice listbox:
import wx
class MyFrame(wx.Frame):
def __init__(self, *args, **kwds):
wx.Frame.__init__(self, *args, style=wx.DEFAULT_FRAME_STYLE)
self.button = wx.Button(self, -1, "Change")
self.Bind(wx.EVT_BUTTON, self.ButtonPress, self.button)
self.tc = wx.TextCtrl(self, -1)
self.lb = wx.ListBox(self, -1, choices = ('One', 'Two'))
box = wx.BoxSizer(wx.VERTICAL)
box.Add(self.lb, 0, wx.EXPAND, 0)
box.Add(self.tc, 0, wx.EXPAND, 0)
box.Add(self.button, 0, wx.ADJUST_MINSIZE, 0)
self.SetSizer(box)
box.Fit(self)
self.Layout()
def ButtonPress(self, evt):
txt = self.tc.GetValue()
pos = self.lb.GetSelection()
self.lb.Delete(pos)
self.lb.Insert(txt, pos)
if __name__ == "__main__":
app = wx.PySimpleApp(0)
frame = MyFrame(None, -1, "")
frame.Show()
app.MainLoop()
If you need multiple-selection listbox, then you should create it with style=wx.LB_MULTIPLE:
self.lb = wx.ListBox(self, -1, choices = ('One', 'Two'), style=wx.LB_MULTIPLE)
Now you're able to change multiple strings at once:
def ButtonPress(self, evt):
txt = self.tc.GetValue()
for pos in self.lb.GetSelections():
self.lb.Delete(pos)
self.lb.Insert(txt, pos)
i am having an interesting problem,

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.
