wxPython GridBagSizer布局

Wx.GridBagSizer(vgap,hgap) 

GridBagsizer類的最重要的方法是Add()，它接受位置作為強制性參數(shù)。 跨度，對齊方式，邊界標(biāo)志和邊框尺寸參數(shù)是可選的。如果沒有明確使用則使用默認(rèn)值。

Wx.GridbagSizer().Add(control, pos, span, flags, border)

以下代碼顯示，其中有與文本框(TexCtrl)相關(guān)聯(lián)的標(biāo)簽(靜態(tài)文本)的表單。用指定跨度的參數(shù)添加TextCtrl對象。 因此，文本框的寬度跨越多個列。對于名稱文本框中跨越了兩列。

tc = wx.TextCtrl(panel) 
sizer.Add(tc, pos = (0, 1), span = (1, 2), flag = wx.EXPAND|wx.ALL, border = 5)

tc1 = wx.TextCtrl(panel,style = wx.TE_MULTILINE) 
sizer.Add(tc1, pos = (1,1), span = (1, 3), flag = wx.EXPAND|wx.ALL, border = 5)

tc4 = wx.TextCtrl(panel,style = wx.TE_MULTILINE) 
sizer.Add(tc4, pos = (3,1), span = (1,3), flag = wx.EXPAND|wx.ALL, border = 5)
sizer.AddGrowableRow(3)
