wxPython.Panel refresh / redraw / update???

[markwalker84]

Hello everyone!

Got a bit of a problem...

Two of the panels on my program contain a number of check boxes. The exact number of which is determined by a pair of variables.

I have recently implemented a Wizard which changes that number, as well as a save and load function to the program.

I know the number of being altered in memory (i added a quick check button) but what i'm struggling with is how to refresh the panel with the new number of chek boxes... very confused!



code time...

from Initials import *
import wx

from Wizard import *


class MainFrame(wx.Frame):
    def __init__(self, parent, title):
        wx.Frame.__init__(self, parent, -1, title)

        icon = wx.Icon("icon.ico", wx.BITMAP_TYPE_ICO)
        self.SetIcon(icon)


        ### Create Main Panel & Sizer ###
        self.mainPanel = wx.Panel(self)
        self.mainPanel.SetBackgroundColour((225,245,255))
        mainSizer = wx.BoxSizer(wx.VERTICAL)


        ### IMPORT VARIABLES LIST FROM INITIALS.PY ###
        self.vars = VariablesData()
        self.variables = self.vars.GetVariables()
        

        ### Create Various Panels ###        
        self.titlePanel = TitlePanel(self.mainPanel, wx.HORIZONTAL, self.variables)
        self.controlPanel = ControlPanel(self.mainPanel, wx.HORIZONTAL, self.variables)
        self.actionPanel = ActionPanel(self.mainPanel, wx.HORIZONTAL, self.variables)

        
        self.CreatemenuBar()
        self.CreateStatusBar()


        mainSizer.Add(self.titlePanel.panel, 2, wx.ALIGN_LEFT | wx.EXPAND | wx.ALL, 5)
        mainSizer.Add(self.controlPanel.panel, 5, wx.EXPAND | wx.LEFT | wx.RIGHT, 5)
        mainSizer.Add(self.actionPanel.panel, 2, wx.EXPAND | wx.ALL, 5)
        
        self.mainPanel.SetSizer(mainSizer)
        mainSizer.Fit(self)                # Fit frame to neccessary size
        mainSizer.SetSizeHints(self)       # Prevents frame from getting smaller than min.

        for x in range(0, self.variables['bristles']):
            self.bristleCheckBox.insert(x, (wx.CheckBox(self.panel, -1, "Bristle %d" % (x+1))))
            self.sizer.Add(self.bristleCheckBox[x], 1, wx.ALIGN_CENTER_HORIZONTAL)

            self.cylinderCheckBox.insert(x, (wx.CheckBox(self.panel, -1, "Cylinder %d" % (x+1))))
            self.sizer.Add(self.cylinderCheckBox[x], 1, wx.ALIGN_CENTER_HORIZONTAL)

class wxPyApp(wx.App):
    def OnInit(self):
        frame = MainFrame(None, "DPT - Sequence Driven Controller")
        self.SetTopWindow(frame)
        frame.Show(True)
        frame.Center(wx.BOTH)
        return True
        
if __name__ == '__main__':          # Only runs if program is being executed, not imported
    app = wxPyApp(redirect=True)
    app.MainLoop()

I know the NewPanel bit isnt the prettiest...

Its the Bristle & Cylinder Panels im having the issue with


Any help would be greatly appreciated!


Thanks,

Have you tried calling self.Refresh()?
I noticed earlier that you don't save the parent. I always assign
self.parent = parent
just in case I need to do something that acts on all the widgets in a frame.
Or you can
parent = self.GetParent( )

There is also wxUpdate() to look at.

i tried self.Refresh() but it didnt seem to do much :-s

where would i include the self.parent = parent line? and also - what exactly would that do? lol

Ive got a sort of make-shift solution 1/2 working where i have a method which destroys all the frames within mainFrame and then another method rebuilds them, but for some reason it will only do this once. Try for a second time and it seems unable to cirrectly build the sizer information and places everything over the top of one another.

I was thinking along the lines of
self.parent.Upd ate()

This space? This thread?

Lol...

Sorry - i got frustrated last night and just went to bed.

Couldnt get it working :-(

I know the variables are being updated as i created a push button -> change label to a variable test panel and it works fine. The problem is in actually re-building the panels... if that makes sense?


ARGH!

If I get some time soon, I'll add a button to a panel dynamically so I know more about what you are going through.

The trick that I've decided to use is

self.thisButton.Hide()

on startup and

self.thisButton.Show()

when I want it visible.

The latter may work on a newly created object, as well.

And if you are trying to show one widget on top of an other:

In the constructor, let the bottom widget be created first. Then let that widget own the (be the parent of) the floater:[CODE=python]# in __init__()

self.grid1 = SingleRowGrid(i d=wxID_SEGMENTC OVERSHEETGRID1, name='grid1', parent=self,
pos=wx.Point(0, 0), size=wx.Size(60 2, 398), style=0)
self.grid1.Bind (wx.grid.EVT_GR ID_CELL_LEFT_CL ICK, self.OnGridCell LeftClick)

self.DatePicker = wx.DatePickerCt rl(id=wxID_SEGM ENTCOVERSHEETDA TEPICKER,
name='datePicke rCtrl1', parent=self.gri d1, pos=wx.Point(20 0, 31), size=wx.Size(10 0,
28),
style=wx.SIMPLE _BORDER | wx.DP_SHOWCENTU RY | wx.DP_DROPDOWN)
self.DatePicker .Raise()
self.DatePicker .Hide()[/CODE]Then, when you want the control shown:[CODE=python]#
def ActivateDatePic ker(self):
self.DatePicker .Refresh()
self.DatePicker .Update()

def OnDatePickerDat eChanged(self, event):
date = event.GetDate() .FormatDate()
self.DatePicker .Hide()
self.grid1.SetC ellValue(0, 0, date)
event.Skip()

def OnGridCellLeftC lick(self, event):
row = event.GetRow()
if row == 0:
self.DatePicker .Show()
wx.FutureCall(1 0, self.ActivateDa tePicker)
else:
self.DatePicker .Hide()
event.Skip()[/CODE]
