Hello,

I have 3 panels and I want to make drags on them. The problem is that when I do a drag on one this happens:

How can I refresh the frame to happear its color when the panel is no longer there?

This is the code that I have to make the drag:

def onMouseMove(self, event):
    (self.pointWidth, self.pointHeight) = event.GetPosition()
    (self.width, self.height) = self.GetSizeTuple()
    if (self.pointWidth>100 and self.pointWidth<(self.width-100) and self.pointHeight < 15) or self.parent.dragging:
        self.SetCursor(wx.StockCursor(wx.CURSOR_SIZING))

        """implement dragging"""
        if not event.Dragging():
            self.w = 0
            self.h = 0
            return
        self.CaptureMouse()
        if self.w == 0 and self.h == 0:
            (self.w, self.h) = event.GetPosition()
        else:
            (posw, posh) = event.GetPosition()
            displacement = self.h - posh
            self.SetPosition( self.GetPosition() - (0, displacement))
    else:
        self.SetCursor(wx.StockCursor(wx.CURSOR_ARROW))

def onDraggingDown(self, event):
    if self.pointWidth>100 and self.pointWidth<(self.width-100) and self.pointHeight < 15:
        self.parent.dragging = 1
        self.SetCursor(wx.StockCursor(wx.CURSOR_ARROW))
        self.SetBackgroundColour('BLUE')
        self.parent.SetTransparent(220)
        self.Refresh()

def onDraggingUp(self, event):
    self.parent.dragging = 0
    self.parent.SetTransparent(255)
    self.SetCursor(wx.StockCursor(wx.CURSOR_ARROW))

and this are the binds for this events:

self.Bind(wx.EVT_MOTION, self.onMouseMove)
self.Bind(wx.EVT_LEFT_DOWN, self.onDraggingDown)
self.Bind(wx.EVT_LEFT_UP, self.onDraggingUp)

With this, if I click on the top of the panel, and move down or up, the panel position changes (I drag the panel) to the position of the mouse.
