python 实现分页显示从es中获取的数据方法
在Python Tkinter中,你可以使用ttk.Treeview小部件实现多选和分页。下面是一个例子:
```python
from tkinter import *
from tkinter import ttk
class Page(Frame):
def __init__(self, master=None):
super().__init__(master)
self.create_widgets()
def create_widgets(self):
self.tree = ttk.Treeview(self)
self.tree["columns"] = ("one", "two")
self.tree.column("one", width=100)
self.tree.column("two", width=100)
self.tree.heading("one", text="Column 1")
self.tree.heading("two", text="Column 2")
for i in range(20):
self.tree.insert("", "end", text=f"Item {i}", values=(f"{i}-1", f"{i}-2"))
self.tree.pack(side="top", fill="both", expand=True)
self.page_frame = Frame(self)
self.page_frame.pack(side="bottom", fill="x")
self.prev_button = Button(self.page_frame, text="Prev", command=self.prev_page)
self.prev_button.pack(side="left")
self.next_button = Button(self.page_frame, text="Next", command=self.next_page)
self.next_button.pack(side="right")
def prev_page(self):
pass # Add code to go to the previous page
def next_page(self):
pass # Add code to go to the next page
root = Tk()
pages = []
for i in range(3):
page = Page(root)
pages.append(page)
notebook = ttk.Notebook(root)
for i, page in enumerate(pages):
notebook.add(page, text=f"Page {i+1}")
notebook.pack()
root.mainloop()
```
这个代码创建了一个包含3个页面的Notebook,每个页面都有一个带有两列的Treeview。我们还添加了一个“Prev”和“Next”按钮,以实现分页。但是,我们还没有实现分页代码,因为它取决于你打算如何选择多个项。
