Hi
I'm not sure if this is the right place to post, pardon me if it's not.
I'm having a problem with an application written with wxpython. The frame
seems only to refresh when moving my mouse of it, though i frequently call:
frame.Refresh(True). In fact, that line is called by another thread, right
after having modified some of the frames attributes.
here are some snippets of code :
class MyFrame(wx.Frame):
def __init__(self, *args, **kwds):
self.queue=Queue.Queue(0)
# begin wxGlade: MyFrame.__init__
kwds["style"] = wx.DEFAULT_FRAME_STYLE
wx.Frame.__init__(self, *args, **kwds)
iconFile = "gnobots2.xpm"
icon1 = wx.Icon(iconFile, wx.BITMAP_TYPE_XPM)
self.SetIcon(icon1)
self.panel_1 = wx.Panel(self, -1)
self.panel_1.Bind(wx.EVT_PAINT, self.on_paint)
self.static_line_1 = wx.StaticLine(self, -1)
self.text_ctrl_1 =
wx.TextCtrl(self, -1,
"",style=wx.TE_MULTILINE|wx.TE_READONLY|wx.TE_WORDWRAP)
self.__set_properties()
self.__do_layout()
# end wxGlade
def __set_properties(self):
# begin wxGlade: MyFrame.__set_properties
self.SetTitle("Simulation")
self.SetSize((600, 400))
self.static_line_1.SetBackgroundColour(wx.Colour(0, 0, 0))
self.text_ctrl_1.SetMinSize((600, 100))
# end wxGlade
self.blues = []
def __do_layout(self):
# begin wxGlade: MyFrame.__do_layout
sizer_1 = wx.BoxSizer(wx.VERTICAL)
sizer_1.Add(self.panel_1, 1, wx.EXPAND, 0)
sizer_1.Add(self.static_line_1, 0, wx.EXPAND, 0)
sizer_1.Add(self.text_ctrl_1, 0, wx.ADJUST_MINSIZE, 0)
self.SetAutoLayout(True)
self.SetSizer(sizer_1)
self.Layout()
# end wxGlade
def on_paint(self, event):
dim = self.panel_1.GetSize()
dc = wx.PaintDC(self.panel_1)
total_types = len(Parameters.DEMANDERS_NUMBERS)
large = dim[1] / (total_types + 3)
long = dim[0] / Parameters.NUMBER_OF_BLUES - 1
for type in range(total_types):
counter = long
for blue in self.blues:
green = (int(blue.biais[type])) * 20
red = - green
if red<0:
red=0
if green<0:
green=0
color = wx.Colour(red, green, 75)
dc.SetPen(wx.Pen(color,long))
dc.DrawLine(counter,50 + (type * (20 +
large)),counter, 50 + large + (ty
pe * (20 + large)))
counter += long
while(not self.queue.empty()):
self.text_ctrl_1.AppendText(str(self.queue.get()) + "\n")
# end of class MyFrame
class MyApp( wx.App):
def OnInit(self):
self.text = ""
self.frame = MyFrame(None , -1, 'Frame Window Demo')
self.frame.Show(True)
self.SetTopWindow(self.frame)
return True
#this is called by an external thread
def paint(self, blues):
self.frame.blues = blues
self.frame.Refresh(True)
I don't know if that is enough information, feel free to ask for more.
