rectangle wont show up on wxpython - python

The rectangle won't show up for me on a windows computer. I gave this to someone else who was a mac user and the rectangle showed up. I am not receiving any errors so I can't seem to figure this out. I am using python 2.7.7.
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()

The problem with this code is that the OP is wanting to draw on the panel, but then proceeds to tell the PaintDC object to paint to the frame. The OnPaint method should look like this:
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)

align wx.DrawCircle to the center of the frame

Hi there I wanted to draw a circle at the center of the Frame.
Is there anything like wx.Align_Center I can use with wx.DrawCircle Below is my code.
#!/usr/bin/python
# points.py
import wx
import random
class Points(wx.Frame):
def __init__(self, parent, id, title):
wx.Frame.__init__(self, parent, id, title, size=(250, 150))
self.Bind(wx.EVT_PAINT, self.OnPaint)
self.Centre()
self.Show(True)
def OnPaint(self, event):
dc = wx.PaintDC(self)
dc.SetBrush(wx.Brush('RED'))
dc.DrawCircle(20,20)
app = wx.App()
Points(None, -1, 'Test')
app.MainLoop()
Just get the size of the frame and then divide the width and the height by 2.
import wx
import random
class Points(wx.Frame):
def __init__(self, parent, id, title):
wx.Frame.__init__(self, parent, id, title, size=(250, 150))
self.Bind(wx.EVT_PAINT, self.OnPaint)
self.Centre()
self.Show(True)
def OnPaint(self, event):
w, h = self.GetClientSize()
dc = wx.PaintDC(self)
dc.SetBrush(wx.Brush('RED'))
dc.DrawCircle(w/2,h/2, 20)
app = wx.App()
Points(None, -1, 'Test')
app.MainLoop()
That will get you pretty close. You might need to tweak the height a bit as I don't think GetSize accounts for the width of the System Menu (the top bar on all windows).

Python - wxPython: Using wx.ClientDC drawing lines, which will disappear after minimize window

I want to draw some lines after click button. But when I minimize the window, or scroll the window in a ScrolledWindow, all the drawing will lost. Is there any way to keep them?
Here is the code:
import wx
class Frame(wx.Frame):
def __init__(self):
wx.Frame.__init__(self, None, -1, size=(640, 480))
self.panel = wx.Panel(self, wx.ID_ANY)
button = wx.Button(self.panel, id=wx.ID_ANY, label=u'Start Calculation', size=(160, 22))
self.Bind(wx.EVT_BUTTON, self.OnButtonCalcuating, button)
def OnButtonCalcuating(self, event):
self.dc = wx.ClientDC(self.panel)
self.dc.DrawLine(50, 60, 190, 60)
if __name__ == '__main__':
app = wx.PySimpleApp()
frame = Frame()
frame.Show()
app.MainLoop()
If you want to paint into your window, you must make a handler for EVT_PAINT event. What you do is, that you paint your line, but that's it. When the window gets re-drawn, and knows nothing about your line anymore.

Buttons on a gradient bar to access different panels

The following code makes a window with a grey gradient bar.
import wx
class GradientFrame(wx.Frame):
def __init__(self, parent, title):
wx.Frame.__init__(self, parent, -1, title)
self.Bind(wx.EVT_PAINT, self.OnPaint)
self.Bind(wx.EVT_ERASE_BACKGROUND, lambda event: None)
self.Bind(wx.EVT_SIZE, self.OnSize)
self.Center()
self.Show()
def OnSize(self, event):
event.Skip()
self.Refresh()
def OnPaint(self, event):
dc = wx.BufferedPaintDC(self)
rect = self.GetClientRect()
dc.SetBackground(wx.Brush("white"))
dc.Clear()
rect.SetHeight(30)
dc.GradientFillLinear(rect, '#fbfbfb', '#efefef', wx.SOUTH)
rect.SetTop(30)
rect.SetHeight(2)
dc.GradientFillLinear(rect, '#dbdbdb', '#c1c1c1', wx.SOUTH)
app = wx.App(0)
frame = GradientFrame(None, 'Test')
app.MainLoop()
I would like to add toogle buttons like the following screenshot, that allows to access to different pages / panels of the GUI (each of them containing their own widgets, etc.)
What is the good framework for that : should these buttons be created manually in OnPaint (this would be very 'low-level') or somewhere else? Is there a ready-to-use way to use buttons linked to different pages ?
There is no good framework for creating custom widgets. However, there are some good recipes out there:
https://stackoverflow.com/questions/1351448/how-to-make-custom-buttons-in-wx
http://wiki.wxpython.org/CreatingCustomControls
Those two links should get you started. You can also take a look at the source for GenericButtons, AquaButton or PlateButton for additional ideas.
Alternatively, you could also just create a panel that's a specific size and put some of the custom buttons or just regular buttons on it instead.
Here's an example of how to use PlateButtons that should get you started:
import wx
import wx.lib.platebtn as platebtn
class GradientFrame(wx.Frame):
def __init__(self, parent, title):
wx.Frame.__init__(self, parent, -1, title)
self.panel = wx.Panel(self)
self.panel.Bind(wx.EVT_PAINT, self.OnPaint)
self.panel.Bind(wx.EVT_ERASE_BACKGROUND, lambda event: None)
self.panel.Bind(wx.EVT_SIZE, self.OnSize)
# add plate buttons
top_sizer = wx.BoxSizer(wx.VERTICAL)
btn_sizer = wx.BoxSizer(wx.HORIZONTAL)
labels = ["Morceaux", "Albums", "Artistes", "Genres"]
style = platebtn.PB_STYLE_GRADIENT
for label in labels:
btn = platebtn.PlateButton(self.panel, label=label, style=style)
btn.SetPressColor(wx.Colour(208,208,208))
btn_sizer.Add(btn, 0, wx.RIGHT|wx.LEFT|wx.CENTER, 5)
top_sizer.Add(btn_sizer, 0, wx.ALL|wx.CENTER, 5)
top_sizer.Add((1,1), 1, wx.EXPAND)
self.panel.SetSizer(top_sizer)
self.Center()
self.Show()
def OnSize(self, event):
event.Skip()
self.Refresh()
def OnPaint(self, event):
dc = wx.BufferedPaintDC(self.panel)
rect = self.panel.GetClientRect()
dc.SetBackground(wx.Brush("white"))
dc.Clear()
rect.SetHeight(30)
dc.GradientFillLinear(rect, '#fbfbfb', '#efefef', wx.SOUTH)
rect.SetTop(30)
rect.SetHeight(2)
dc.GradientFillLinear(rect, '#dbdbdb', '#c1c1c1', wx.SOUTH)
app = wx.App(0)
frame = GradientFrame(None, 'Test')
app.MainLoop()

Wxpython Switching frames between two python files

i have two py files that each have its own frame made using wxPython, MainWindow and RecWindow. MainWindow has the RecWindow python file included using the keyword "recovery".
MainWindow code:
class MainWindow(wx.Frame):
def __init__(self,parent,id,title):
wx.Frame.__init__(self, parent, wx.ID_ANY,title,pos=(500,200), size = (650,500), style = wx.DEFAULT_FRAME_STYLE | wx.NO_FULL_REPAINT_ON_RESIZE)
self.Bind(wx.EVT_CLOSE,self.OnExit)
self.SetIcon(wx.Icon('etc\icons\download.ico', wx.BITMAP_TYPE_ICO))
panel = wx.Panel(self)
RecWindow code:
class RecWindow(wx.Frame):
def __init__(self,parent,id,title):
wx.Frame.__init__(self, parent, wx.ID_ANY,title,pos=(400,200), size = (700,600), style = wx.DEFAULT_FRAME_STYLE | wx.NO_FULL_REPAINT_ON_RESIZE)
self.SetIcon(wx.Icon('etc\icons\download.ico', wx.BITMAP_TYPE_ICO))
self.count = 0
when i click on a button in MainWindow , it will hide the MainWindow create an instance of RecWindow, shown below;
def OpenRec(self,event):#this will be used to open the next frame
OR = recovery(None,-1,"RAVE")
OR.Show(True)
MainWindow.Hide()
now, what i am unsure of is how i can return to the MainWindow once i close the RecWindow. RecWindow has a cancel and finish button which both map to a self.close() function. How would i then get MainWindow to show itself again?
Use pubsub to send a message to the main window telling it to Show itself again. I actually have an example of how to do that here:
http://www.blog.pythonlibrary.org/2010/06/27/wxpython-and-pubsub-a-simple-tutorial/
Note that this tutorial is using slightly older API that was available in wxPython 2.8. If you're using wxPython 2.9, then you'll have to use the slightly different API that I detail in this article:
http://www.blog.pythonlibrary.org/2013/09/05/wxpython-2-9-and-the-newer-pubsub-api-a-simple-tutorial/
When you create an instance of RecWindow keep a reference to it on main_window and bind to its close event.
In the main_window's close handler check if the window closed was the RecWindow.
If it was, clear the reference to it and show the main_window.
Elif the closed window was main_window carry out any required code.
Finally call event.Skip() so the windows get destroyed.
import wx
class MainWindow(wx.Frame):
def __init__(self, parent, title):
wx.Frame.__init__(self, parent, -1, title, (500, 200), (650, 500),
wx.DEFAULT_FRAME_STYLE | wx.NO_FULL_REPAINT_ON_RESIZE)
panel = wx.Panel(self)
button = wx.Button(panel, wx.ID_OPEN)
panel.sizer = wx.BoxSizer(wx.VERTICAL)
panel.sizer.Add(button, 0, wx.ALL, 7)
panel.SetSizer(panel.sizer)
button.Bind(wx.EVT_BUTTON, self.on_button)
self.Bind(wx.EVT_CLOSE, self.on_close)
self.rec_window = None
def on_button(self, event):
rec_window = RecWindow(self, 'Rec window')
rec_window.Show()
self.Hide()
rec_window.Bind(wx.EVT_CLOSE, self.on_close)
self.rec_window = rec_window
def on_close(self, event):
closed_window = event.EventObject
if closed_window == self.rec_window:
self.rec_window = None
self.Show()
elif closed_window == self:
print 'Carry out your code for when Main window closes'
event.Skip()
class RecWindow(wx.Frame):
def __init__(self, parent, title):
wx.Frame.__init__(self, parent, -1, title, (400, 200), (700, 600),
wx.DEFAULT_FRAME_STYLE | wx.NO_FULL_REPAINT_ON_RESIZE)
app = wx.App(False)
main_window = MainWindow(None, 'Main window')
main_window.Show()
app.MainLoop()

Animating gif in wxPython

I'm trying to animate a gif using wx-Python (2.7). The code listed below works but i want to create a function that animates the gif for me, so i can use it elsewhere. I've tried searching the internet but i can only find code that animates the gif within the __init__ function. Any ideas?
# -*- coding: cp1252 -*-
import wx
import wx.animate
class MyPanel(wx.Panel):
def __init__(self, parent, id):
wx.Panel.__init__(self, parent, id)
self.SetBackgroundColour("black")
gif_fname = "skYmk.gif"
gif = wx.animate.GIFAnimationCtrl(self, id, gif_fname, pos=(10, 10))
gif.GetPlayer().UseBackgroundColour(True)
gif.Play()
app = wx.PySimpleApp()
frame = wx.Frame(None, -1, "wx.animate.GIFAnimationCtrl()", size = (200, 220))
MyPanel(frame, -1)
frame.Show(True)
app.MainLoop()
I don't understand your issue.... what is the problem in doing something like this?
import wx
import wx.animate
class MyPanel(wx.Panel):
def __init__(self, parent, id):
wx.Panel.__init__(self, parent, id)
self.SetBackgroundColour("black")
gif_fname = "skYmk.gif"
gif = wx.animate.GIFAnimationCtrl(self, id, gif_fname, pos=(10, 10))
gif.GetPlayer().UseBackgroundColour(True)
self.gif = gif
def CallMeLater(self, play=True):
if play:
self.gif.Play()
else:
self.gif.Stop()
app = wx.PySimpleApp()
frame = wx.Frame(None, -1, "wx.animate.GIFAnimationCtrl()", size = (200, 220))
MyPanel(frame, -1)
frame.Show(True)
app.MainLoop()
