python - Update wxPython grid in real time -
i extracting data huge log , updating entry in wxpython grid. code have can see window after operation complete, takes 5 mins complete operation. there way update , see data on grid time = 0 itself. tried:
import wx import wx.grid gridlib class myform(wx.frame): def __init__(self): ## # constructor create basic frame wx.frame.__init__(self, none, wx.id_any, "tool") # add panel looks correct on platforms panel = wx.panel(self, wx.id_any) self.grid = gridlib.grid(panel) rows = 4 column = 600000 self.grid.creategrid(column, rows) self.count = 0 # change couple column labels self.grid.setcollabelvalue(0, "timestamp") self.grid.setcollabelvalue(1, "cmd") self.grid.setcollabelvalue(2, "address") self.grid.setcollabelvalue(3, "data") # few more operations calculate cmd,timestamp field in range(10**5): self.count += 1 self.grid.setcellvalue(self.count,1,'cmd4') self.grid.setcellvalue(self.count,0,str(self.count)) self.grid.setcellvalue(self.count, 2, "extracted address") self.grid.setcellvalue(self.count, 3, "extracted data") # change row labels sizer = wx.boxsizer(wx.vertical) sizer.add(self.grid, 1, wx.expand, 5) panel.setsizer(sizer) if __name__ == "__main__": app = wx.app() frame = myform() frame.show() app.mainloop()
use wx.yield() hand control main loop.
here use divmod every 1000th iteration , call wx.yield.
use movecursordownblock allow visually follow updating grid.
may wish remove or amend this, slow down execution of program.
