在wxPython中创建一个Dialog并包含一棵树,首先你需要导入必要的库,如`wx`(用于窗口和控件)、`wx.lib.mixins.inspection`(提供一些调试工具,包括TreeCtrl),然后按照以下步骤操作:
```python
import wx
from wx.lib.mixins.inspection import InspectableTreeCtrlMixin
class TreeDialog(wx.Dialog, InspectableTreeCtrlMixin):
def __init__(self, parent=None, title="Tree Dialog", tree_data=[]):
super().__init__(parent=parent, title=title)
# 创建树控件
self.tree = wx.TreeCtrl(self, style=wx.TR_DEFAULT_STYLE | wx.TR_TWISTED | wx.TR_HAS_BUTTONS)
# 初始化树的数据结构
self._build_tree(tree_data)
# 添加到对话框布局
sizer = wx.BoxSizer(wx.VERTICAL)
sizer.Add(self.tree, proportion=1, flag=wx.EXPAND)
self.SetSizer(sizer)
def _build_tree(self, data):
root = self.tree.AddRoot("根节点")
for item in data:
self.tree.AppendItem(root, str(item))
def OnTreeSelChanged(self, event):
# 树选择改变事件处理
selected_item = self.tree.GetSelection()
if selected_item:
print(f"选中的项:{self.tree.GetItemText(selected_item)}")
# 示例数据
tree_data = ["一级节点1", "一级节点2", {"二级节点": "三级节点"}]
# 创建并显示对话框
dialog = TreeDialog(None)
if dialog.ShowModal() == wx.ID_OK:
print("用户点击了确定按钮")
dialog.Destroy()
