Tkinter Treeview 插入图像

Tkinter Treeview 插入图像

在insert( )方法内若是增加image参数可以添加图像，在添加图像时需要考虑的是可能row的高度不足，所以必须增加高度。这时可以用下列Style( )方法处理。

Style().configure("TreeView", rowHeight=xx)  # xx 是高度设置

示例1

设计一个含有图像的Treeview。

from tkinter import *
from tkinter.ttk import *
from PIL import Image, ImageTk

root = Tk()
root.title("apidemos.com")

Style().configure("Treeview",rowheight=35)  # 格式化扩充row高度

info = ["The Phoenix News App provides access to the latest news from around China",
        "Swiss National Rail App provides all Swiss train schedules",
        "Coca-Cola App is a software for entertainment"]

tree = Treeview(root,columns=("Description"))
tree.heading("#0",text="App")              # 图标栏
tree.heading("#1",text="Function Description")
tree.column("#1",width=300)                # 格式化栏标题

img1 = Image.open("apidemos.png")           # Insert apidemos.png
imgObj1 = ImageTk.PhotoImage(img1)
tree.insert("",index=END,text="Phoenix News",image=imgObj1,values=info[0])

img2 = Image.open("apidemos.png")           # Insert apidemos.png
imgObj2 = ImageTk.PhotoImage(img2)
tree.insert("",index=END,text="Swiss Railways",image=imgObj2,values=info[1])

img3 = Image.open("apidemos.png")           # Insert apidemos.png
imgObj3 = ImageTk.PhotoImage(img3)         
tree.insert("",index=END,text="Coca-Cola",image=imgObj3,values=info[2])
tree.pack()

root.mainloop()

输出:
