• Find all nested SizerItems within a Frame in wxPython

  In wxPython, I am trying to adjust the border of items within a form on startup programatically in order to support higher DPI displays a bit better. I want to do is loop through each item in the frame (i.e. each row as shown in the editor) and double the "border" attribute if it has one. This mostly works great. However, some sizers I'm unable to find programmatically, specifically those which are nested inside other sizers.

  I've recreated this on a simplified form:

  I have set the border of each item to unique values so that I know which ones have been hit.

  • panel1: border of 1
  • hiddenSizer: border of 2
  • bSizer261: border of 3
  • bSizer27: border of 4
  • bSizer28: border of 5
  • bSizer29: border of 6
  • m_staticText29: border of 7

  My code to (attempt to) find all SizerItems is the following:

  import wx
  
  def walk_children(item):
      for value in item.GetChildren():
          yield value
          for subvalue in walk_children(value):
              yield subvalue
  
  def adjust_border(frame : wx.Window):
      for x in walk_children(frame):
          print()
          sizer = x.GetContainingSizer()
          parents = [x]
          while parents[-1].GetParent():
              parents.append(parents[-1].GetParent())
          print(x, sizer)
          print(f"parents: {parents}")
          if sizer:
              for x in sizer.GetChildren():
                  print(x, x.GetBorder())
                  x.SetBorder(x.GetBorder() * 2)

          self.SetSizeHints( wx.DefaultSize, wx.DefaultSize )

          self.panel1 = wx.Panel( self, wx.ID_ANY, wx.DefaultPosition, wx.DefaultSize, wx.TAB_TRAVERSAL )
          bSizer23 = wx.BoxSizer( wx.VERTICAL )
          hiddenSizer = wx.StaticBoxSizer( wx.StaticBox( self.panel1, wx.ID_ANY, u"Top Panel" ), wx.VERTICAL )
          bSizer261 = wx.BoxSizer( wx.VERTICAL )
          bSizer27 = wx.BoxSizer( wx.VERTICAL )
          bSizer28 = wx.BoxSizer( wx.VERTICAL )
          bSizer29 = wx.BoxSizer( wx.VERTICAL )
          self.m_staticText29 = wx.StaticText( hiddenSizer.GetStaticBox(), wx.ID_ANY, u"MyLabel", wx.DefaultPosition, wx.DefaultSize, 0 )
          self.m_staticText29.Wrap( -1 )
          bSizer29.Add( self.m_staticText29, 0, wx.ALL, 7 )
          bSizer28.Add( bSizer29, 1, wx.ALL|wx.EXPAND, 6 )
          bSizer27.Add( bSizer28, 1, wx.ALL|wx.EXPAND, 5 )
          bSizer261.Add( bSizer27, 1, wx.ALL|wx.EXPAND, 4 )
          hiddenSizer.Add( bSizer261, 1, wx.ALL|wx.EXPAND, 3 )
          bSizer23.Add( hiddenSizer, 1, wx.ALL|wx.EXPAND, 2 )
          self.panel1.SetSizer( bSizer23 )
          self.panel1.Layout()
          bSizer23.Fit( self.panel1 )
          bSizer1.Add( self.panel1, 1, wx.EXPAND |wx.ALL, 1 )
          self.SetSizer( bSizer1 )

          # initialize
          super().__init__(parent)

          adjust_border(self)
  
  
  def run_gui():
      # create the window
      app = wx.App()
      ex = MainFrame(None)
      ex.Show()
      app.MainLoop()
  
  
  if __name__ == "__main__":
      run_gui()
  

  The output is this which indicates only 3/7 of them haved been found (those with borders of 1, 3, and 7:

  How do I loop through each SizerItem in a frame programmatically without skipping entries?

• Creating an animation showing a line dropping vertically using wxPython

  I wrote a code showing a line dropping vertically using wxPython. The issue Iam facing is when I keep the same y-coordinate (y2=y4 :drawing horizontal line on frame), the line is not visible on the window.

  If I change the 4th parameter of the DrawLine(...) call by 1 unit (size[1]/2 -300+i*10 => size[1]/2 -301+i*10), the line is visible.

  Can anyone explain where Iam going wrong.

  My code where I kept same y-coordinate to draw horizontal line is below. In this case, line is not visible.

  import wx;
  import time;
  
  app = wx.App();
  frame=wx.Frame(None,-1,'Line');
  frame.SetBackgroundColour('White');
  frame.Centre();
  frame.Show();
  frame.Maximize();
  dc=wx.ClientDC(frame);
  size=dc.GetSize();
  for i in range(1,50):
      dc.SetPen(wx.Pen('VIOLET'));
      dc.DrawLine(size[0] / 2-500, size[1]/2-300+i*10, size[0] / 2 , size[1]/2 -300+i*10);
      time.sleep(0.2);
      dc.SetPen(wx.Pen('WHITE')); # the pen is set to white and same line is drown to create the animation
      dc.DrawLine(size[0] / 2-500, size[1]/2-300+i*10, size[0] / 2 , size[1]/2 -300+i*10);
  app.MainLoop();
  

  Now, if I change y-coordinate by even by 1 unit (y4=y2+1), the line is visible and the animation is shown on the frame. The code is below

  import wx;
  import time;
  
  app = wx.App();
  frame=wx.Frame(None,-1,'Line');
  frame.SetBackgroundColour('White');
  frame.Centre();
  frame.Show();
  frame.Maximize();
  dc=wx.ClientDC(frame);
  size=dc.GetSize();
  for i in range(1,50):
      dc.SetPen(wx.Pen('VIOLET'));
      dc.DrawLine(size[0] / 2-500, size[1]/2-300+i*10, size[0] / 2 , size[1]/2 -301+i*10);
      time.sleep(0.2);
      dc.SetPen(wx.Pen('WHITE')); # the pen is set to white and same line is drown to create the animation
      dc.DrawLine(size[0] / 2-500, size[1]/2-300+i*10, size[0] / 2 , size[1]/2 -301+i*10);
  app.MainLoop();
  

  Can anyone explain why this difference or where Iam going wrong?
• Align two differents graphs (ggplot) using same class of x axis but differents

  i try to align two differents ggplot, using times series in x.axis (POSIXt) : one graph below the other one. I want the date to be perfectly aligned, despite the y labels that take place on the left for one and the legends take place on the right for the other one.

  I have tried egg package, and cowboy package but they both use in their example a unique database, which seems to be simplier. And I don't make it with these one

  Do you idea of some package than can help me with this case?

  Thank you
• Multiple 3d models are puted but only one is showing in unity3d

  I had created a egg basket app to put a particular colour egg in that particular coloured basket but when I put multiple eggs with same colour in a basket only one egg is showing and the score is increasing as the number of baskets I put. Please guide me how I can make appear all eggs which are puted into basket...?
