wxPython高级窗口
分隔窗口
import wx
# 自定义窗口类MyFrame
class MyFrame(wx.Frame):
def __init__(self):
super().__init__(parent=None, title='分隔窗口', size=(400, 300))
self.Center() # 设置窗口居中
#分隔窗口
splitter = wx.SplitterWindow(self, -1)
#分成左面板和右面板
leftpanel = wx.Panel(splitter)
rightpanel = wx.Panel(splitter)
#100位左面板的尺寸
splitter.SplitVertically(leftpanel, rightpanel, 100)
#设置面板最小值
splitter.SetMinimumPaneSize(80)
list2 = ['苹果', '橘子', '香蕉']
#设置列表
lb2 = wx.ListBox(leftpanel, -1, choices=list2, style=wx.LB_SINGLE)
self.Bind(wx.EVT_LISTBOX, self.on_listbox, lb2)
#在左面板放个列表
vbox1 = wx.BoxSizer(wx.VERTICAL)
vbox1.Add(lb2, 1, flag=wx.ALL | wx.EXPAND, border=5)
leftpanel.SetSizer(vbox1)
#右面板放个文本
vbox2 = wx.BoxSizer(wx.VERTICAL)
self.content = wx.StaticText(rightpanel, label='右侧面板')
vbox2.Add(self.content, 1, flag=wx.ALL | wx.EXPAND, border=5)
rightpanel.SetSizer(vbox2)
def on_listbox(self, event):
s = '选择 {0}'.format(event.GetString())
self.content.SetLabel(s)
class App(wx.App):
def OnInit(self):
# 创建窗口对象
frame = MyFrame()
frame.Show()
return True
if __name__ == '__main__':
app = App()
app.MainLoop() # 进入主事件循环
树
树是一种通过层次结构展示信息的控件，在wxPyhton中树控件类是wx.TreeCtrl
import wx
# 自定义窗口类MyFrame
class MyFrame(wx.Frame):
def __init__(self):
super().__init__(parent=None, title='树控件', size=(500, 400))
self.Center() # 设置窗口居中
splitter = wx.SplitterWindow(self)
leftpanel = wx.Panel(splitter)
rightpanel = wx.Panel(splitter)
splitter.SplitVertically(leftpanel, rightpanel, 200)
splitter.SetMinimumPaneSize(80)
#创建树
self.tree = self.CreateTreeCtrl(leftpanel)
self.Bind(wx.EVT_TREE_SEL_CHANGING, self.on_click, self.tree)
vbox1 = wx.BoxSizer(wx.VERTICAL)
vbox1.Add(self.tree, 1, flag=wx.ALL | wx.EXPAND, border=5)
leftpanel.SetSizer(vbox1)
vbox2 = wx.BoxSizer(wx.VERTICAL)
self.content = wx.StaticText(rightpanel, label='右侧面板')
vbox2.Add(self.content, 1, flag=wx.ALL | wx.EXPAND, border=5)
rightpanel.SetSizer(vbox2)
def on_click(self, event):
item = event.GetItem()
self.content.SetLabel(self.tree.GetItemText(item))
def CreateTreeCtrl(self, parent):
tree = wx.TreeCtrl(parent)
items = []
#图像列表，存放wx.TreeCtrl使用的图片
imglist = wx.ImageList(16, 16, True, 2)
imglist.Add(wx.ArtProvider.GetBitmap(wx.ART_FOLDER, size=wx.Size(16, 16)))
imglist.Add(wx.ArtProvider.GetBitmap(wx.ART_NORMAL_FILE, size=wx.Size(16, 16)))
#保存wx.ImageList图像列表到树种，这样后续方法就可以图像列表中的索引了
tree.AssignImageList(imglist)
#添加根节点，返回节点类型为wx.TreeItemId, image为选中图像的索引
root = tree.AddRoot("TreeRoot", image=0)
#添加子节点
items.append(tree.AppendItem(root, "Item 1", 0))
items.append(tree.AppendItem(root, "Item 2", 0))
items.append(tree.AppendItem(root, "Item 3", 0))
items.append(tree.AppendItem(root, "Item 4", 0))
items.append(tree.AppendItem(root, "Item 5", 0))
for ii in range(len(items)):
id = items[ii]
tree.AppendItem(id, "Subitem 1", 1)
tree.AppendItem(id, "Subitem 2", 1)
tree.AppendItem(id, "Subitem 3", 1)
tree.AppendItem(id, "Subitem 4", 1)
tree.AppendItem(id, "Subitem 5", 1)
tree.Expand(root) # 展开根下子节点， 若要展开所有子节点采用ExpandAllChildren(root)
tree.Expand(items[0]) # 展开Item 1下子节点
tree.SelectItem(root) # 选中根节点
return tree
class App(wx.App):
def OnInit(self):
# 创建窗口对象
frame = MyFrame()
frame.Show()
return True
if __name__ == '__main__':
app = App()
app.MainLoop() # 进入主事件循环
网格控件
wxPython网格类是采用wx.grid.Grid,但该方法添加单元格数据较麻烦，而且对网格的控制也很少，
为此可以使用wx.grid.GridTableBase抽象类，自己实现一些方法
