I am trying to make chat client where I get the user input and display it on the white rectangle I am trying to draw. I try drawing the rectangle on the panel but I get this error
Traceback (most recent call last):

panel.SetBackgroundColour("#E6E6E6")

dc = wx.PaintDC(self)
dc.SetPen(wx.Pen('#d4d4d4'))
dc.SetBrush(wx.Brush('#c56c00'))
dc.DrawRectangle(10, 15, 90, 60)
self.Show(True)

I believe I answered this already in the OP's other question , which is basically the same as this one.
def OnPaint(self, event):
dc = wx.PaintDC(self.panel) # <<< This was changed
dc.SetPen(wx.Pen('#d4d4d4'))
dc.SetBrush(wx.Brush('#c56c00'))
dc.DrawRectangle(10, 15, 90, 60)
You want to draw to the panel, NOT the frame. In the OP's code, they are telling wx.PaintDC to draw to self, which refers to the frame. I don't know why this would work on one OS except by happenstance. The fact that it worked for @user667648 is weird. I would file that as a bug. The proper way to draw to the panel is the above.
This line:
self.panel.Bind(wx.EVT_PAINT, self.OnPaint)
Should be:
panel.Bind(wx.EVT_PAINT, self.OnPaint)
Your class has no attribute panel
, but it does have a local variable in init called panel
.
Alternatively, you could consider making panel an attribute:
import socket
import wx
class WindowFrame(wx.Frame):
def __init__(self, parent, title):
wx.Frame.__init__(self, parent, title = title, size=(500, 400))
self.panel=wx.Panel(self)
self.panel.SetBackgroundColour("#E6E6E6")
self.control = wx.TextCtrl(self.panel, style = wx.TE_MULTILINE, size =(410, 28), pos=(0,329))
sendbutton=wx.Button(self.panel, label ="Send", pos =(414,325), size=(65,35))
self.panel.Bind(wx.EVT_PAINT, self.OnPaint)
self.Centre()
self.Show()
def OnPaint(self, event):
dc = wx.PaintDC(self)
dc.SetPen(wx.Pen('#d4d4d4'))
dc.SetBrush(wx.Brush('#c56c00'))
dc.DrawRectangle(10, 15, 90, 60)
self.Show(True)
if __name__=="__main__":
app = wx.App(False)
frame = WindowFrame(None, 'ChatClient')
app.MainLoop()
EDIT: As Mike points out there is another issue with the drawing routine. Interesting how my computer doesn't complain about this...
