如何在多个网格条目tkinter中填充数据

Question

老板

我观察到我的代码执行正确并成功调整了网格列的大小；然而，该牢房仍然无人居住。我想使用数据库、Excel 文件或数据框中的数据填充单元格或输入框。此外，我寻求有关如何根据特定行或列号填充单元格的指导。

看我的代码

import tkinter as tk

class ResizableGrid(tk.Frame):
    def __init__(self, parent, rows, columns, *args, **kwargs):
        tk.Frame.__init__(self, parent, *args, **kwargs)

        self.rows = rows
        self.columns = columns

        self.entry_grid = [[tk.Entry(self,cursor="circle") for _ in range(columns)] for _ in range(rows)]
#        self.entry_grid.insert(0, "Hello, world")    # how to fill grid entry by my databse data or fill by row and column 
# $self.entry_grid.insert(0, rows+colmun)  
        self.configure_grid()

        self.bind_mouse()

    def configure_grid(self):
        for i in range(self.rows):
            for j in range(self.columns):
                self.entry_grid[i][j].grid(row=i, column=j,sticky="nsew", padx=1, pady=1)
                self.entry_grid[i][j].bind("<Enter>", lambda event, col=j: self.on_enter(event, col))
                
        for i in range(self.rows):
            self.grid_rowconfigure(i, weight=1)

        for j in range(self.columns):
            self.grid_columnconfigure(j, weight=1)

    def bind_mouse(self):
        self.bind("<B1-Motion>", self.on_motion)
        self.bind("<ButtonRelease-1>", self.on_release)

    def on_enter(self, event, col):
        self.current_column = col

    def on_motion(self, event):
        if hasattr(self, "current_column"):
            col = self.current_column
            width = event.x - self.entry_grid[0][col].winfo_x()
            self.columnconfigure(col, minsize=max(50, width))

    def on_release(self, event):
        if hasattr(self, "current_column"):
            delattr(self, "current_column")

if __name__ == "__main__":
    root = tk.Tk()
    root.title("Resizable Grid")
    rows = 5
    columns = 8
    grid = ResizableGrid(root, rows, columns)
    grid.pack(expand=True, fill="both")
    root.mainloop()

self.entry_grid.insert(0, "Hello, world")

Answer 1

您可以在类中的第 2 行第 3 列处插入类似以下内容：

self.entry_grid[2][3].insert(0, "Hello, world (2,3)") 

这里在类外的第 4 行第 5 列中插入一些内容：

grid.entry_grid[4][5].insert(0, "Hello, world (4,5)")
