如何在树视图中使用水平滚动，这里我使用树视图制作表格 [英] How to use horizontal scrolling in treeview,here i use tree view to make a table

问题描述

class table(Frame):

def __init__(self, parent,headings=None,data=None):
    Frame.__init__(self, parent,relief='ridge')
    self.parent=parent
    self.headings=headings
    self.data = data
    self.CreateUI(self.headings)
    self.LoadTable(self.data)


    self.yscrollbar = Scrollbar(self.parent,orient=VERTICAL)
    self.yscrollbar.grid(row=0,column=1,sticky = (N,S,W,E))
    self.yscrollbar.config(command=self.treeview.yview)
    self.treeview.config(yscrollcommand=self.yscrollbar.set)

    self.xscrollbar = Scrollbar(self.parent,orient=HORIZONTAL)
    self.xscrollbar.grid(row=1,column=0,sticky = (N,S,W,E))
    self.treeview.config(xscrollcommand=self.xscrollbar.set)
    self.xscrollbar.config(command=self.treeview.xview)

    self.grid(row=0,column=0)
def CreateUI(self,headings):
    tv = Treeview(self,height=20)
    if(headings==None):
        tv['columns'] = ('starttime', 'endtime', 'status')
    else:
        tv['columns'] = headings[1:]
        tv.heading("#0", text=headings[0], anchor='w')
        tv.column("#0", anchor="w")
        for i in headings[1:]:
            tv.heading(i, text=i)
            tv.column(i, anchor='center')
    tv.grid(sticky = (N,S,W,E))
    self.treeview = tv

def LoadTable(self,data):
    if(data==None):
        for i in range(100):
            self.treeview.insert('', 'end', text="first", values=('sdfa','asdfasd0','asdfasdf'))
            self.treeview.insert('', 'end', text="Second", values=('sdfa','asdfasd0','asdfasdf'))
            self.treeview.insert('', 'end', text="third", values=('sdfa','asdfasd0','asdfasdf'))
    else:
        for line in data:
            self.treeview.insert('', 'end', text=line[0], values=line[1:])

根据上面的代码，我从树视图中创建了一个表格，我的 y 轴滚动工作正常，但我无法在 xscrollbar 上工作.请帮助我谢谢.我附上了一张生成的 Treeview 的图像(像一张桌子).我的 tkinter 窗口截图

From the above code i created a table out of a treeview, my y-axis scroll is working perfect, but i am not able to work on the xscrollbar. kindly help me out thank you. I am attaching one image of the resultant Treeview(table like one). screeshot of my tkinter window

推荐答案

def CreateUI(self,headings):
    tv = Treeview(self,height=20)
    if(headings==None):
        tv['columns'] = ('starttime', 'endtime', 'status')
    else:
        tv['columns'] = headings[1:]
        tv.heading("#0", text=headings[0], anchor='w')
    --> tv.column("#0", anchor="center",width=100,minwidth=100)
        for i in headings[1:]:
            tv.heading(i, text=i)
        --> tv.column(i, anchor='center',width=90,minwidth=100)##
    tv.pack(expand=Y)
    self.treeview = tv

此功能中的一些编辑帮助我完成了，感谢那些尝试过的人.我使用了树视图的一个额外参数，即最小宽度.宽度和最小宽度的差异将使我们能够解决这个问题.

some edit in this function helped me through, thank you for those who tried. I used an extra parameter of the treeview i.e. , the minwidth. having a difference in width and min width will allow us to go through this issue.
