Layout management in wxPythonhttp://www.zetcode.com/wxpython/layout/self.Bind(wx.EVT_MENU, self.OnClose, id=1)sizer = wx.BoxSizer(wx.VERTICAL)self.display = wx.TextCtrl(self, -1, '', style=wx.TE_RIGHT)sizer.Add(self.display, 0, wx.EXPAND | wx.TOP | wx.BOTTOM, 4)gs = wx.GridSizer(4, 4, 3, 3)gs.AddMany( [(wx.Button(self, -1, 'Cls'), 0, wx.EXPAND),(wx.Button(self, -1, 'Bck'), 0, wx.EXPAND),(wx.StaticText(self, -1, ''), 0, wx.EXPAND),(wx.Button(self, -1, 'Close'), 0, wx.EXPAND),(wx.Button(self, -1, '7'), 0, wx.EXPAND),(wx.Button(self, -1, '8'), 0, wx.EXPAND),(wx.Button(self, -1, '9'), 0, wx.EXPAND),(wx.Button(self, -1, '/'), 0, wx.EXPAND),(wx.Button(self, -1, '4'), 0, wx.EXPAND),(wx.Button(self, -1, '5'), 0, wx.EXPAND),(wx.Button(self, -1, '6'), 0, wx.EXPAND),(wx.Button(self, -1, '*'), 0, wx.EXPAND),(wx.Button(self, -1, '1'), 0, wx.EXPAND),(wx.Button(self, -1, '2'), 0, wx.EXPAND),(wx.Button(self, -1, '3'), 0, wx.EXPAND),(wx.Button(self, -1, '-'), 0, wx.EXPAND),(wx.Button(self, -1, '0'), 0, wx.EXPAND),(wx.Button(self, -1, '.'), 0, wx.EXPAND),(wx.Button(self, -1, '='), 0, wx.EXPAND),(wx.Button(self, -1, '+'), 0, wx.EXPAND) ])sizer.Add(gs, 1, wx.EXPAND)self.SetSizer(sizer)self.Centre()self.Show(True)def OnClose(self, event):self.Close()app = wx.App()GridSizer(None, -1, 'GridSizer')app.MainLoop()Notice how we managed to put a space between the Bck and the Close buttons. Wesimply put an empty wx.StaticText there. Such tricks are quite common.In our example we used the AddMany() method. It is a convenience method foradding multiple widgets at one time.AddMany(list items)Widgets are placed inside the table in the order, they are added. The first row is filledfirst, then the second row etc.wx.FlexGridSizerThis sizer is similar to wx.GridSizer. It does also lay out it's widgets in a twodimensional table. It adds some flexibility to it. wx.GridSizer cells are of the samesize. All cells in wx.FlexGridSizer have the same height in a row. All cells have thesame width in a column. But all rows and columns are not necessarily the sameheight or width.wx.FlexGridSizer(int rows=1, int cols=0, int vgap=0, int hgap=0)rows and cols specify the number of rows and columns in a sizer. vgap and hgap addsome space between widgets in both directions.Many times developers have to develop dialogs for data input and modification. I findwx.FlexGridSizer suitable for such a task. A developer can easily set up a dialog10 de 17 27/04/2008 1:03
