用Python辅助生成Python代码计划

用GUI界面生成一个窗体

import tkinter as tk
win = tk.Tk()
win.geometry("600x400+800+400")
win.title("tkWindow代码生成器")
# 申明字符变量
title_var = tk.StringVar()
w_var = tk.StringVar()
h_var = tk.StringVar()
# 标题
labTitle = tk.Label(win)
labTitle["text"] = "标题"
labTitle.place(x=10,y=10)
txtTitle = tk.Entry(win,textvariable = title_var)
txtTitle.place(x=60,y=10)
# 宽度x高度
labWH = tk.Label(win)
labWH["text"] = "宽x高"
labWH.place(x=10,y=40)
txtW = tk.Entry(win,textvariable = w_var)
txtW["width"] = 5 
txtW.place(x=60,y=40)
txtH = tk.Entry(win,textvariable = h_var)
txtH["width"] = 5 
txtH.place(x=130,y=40)
def run_Window():
    global new_win
    global title_var
    global h_var
    global w_var
    new_win = tk.Tk()
    new_win.geometry(w_var.get() + "x" + h_var.get())
    new_win.title(title_var.get()) 
    new_win.mainloop()
# 运行按钮
btnRun = tk.Button(win)
btnRun["text"] = "运行"
btnRun["width"] = 20
btnRun["height"] = 3
btnRun["command"] = run_Window
btnRun.place(x=10,y=70)
def close_Window():
    new_win.destroy()
# 停止按钮
btnRun = tk.Button(win)
btnRun["text"] = "停止"
btnRun["width"] = 20
btnRun["height"] = 3
btnRun["command"] = close_Window
btnRun.place(x=10,y=140)
win.mainloop()

上面的实现是直接基于事件处理代码中重新创建一个窗体，然后用mainloop（）执行，用destroy()进行关闭。

改进

实现代码的显示，以及只允许一个窗体实例运行。

import tkinter as tk
win = tk.Tk()
win.geometry("600x400+800+400")
win.title("tkWindow代码生成器")
# 申明字符变量
title_var = tk.StringVar()
w_var = tk.StringVar()
h_var = tk.StringVar()
code_var = tk.StringVar()
# 标题
labTitle = tk.Label(win)
labTitle["text"] = "标题"
labTitle.place(x=10,y=10)
txtTitle = tk.Entry(win,textvariable = title_var)
txtTitle.place(x=60,y=10)
# 宽度x高度
labWH = tk.Label(win)
labWH["text"] = "宽x高"
labWH.place(x=10,y=40)
txtW = tk.Entry(win,textvariable = w_var)
txtW["width"] = 5 
txtW.place(x=60,y=40)
txtH = tk.Entry(win,textvariable = h_var)
txtH["width"] = 5 
txtH.place(x=130,y=40)
has_Run = False #是否已经有一个窗体实例运行
def run_Window():
    global new_win
    global title_var
    global h_var
    global w_var
    global code_var
    global has_Run
    if has_Run == False:
        new_win = tk.Tk()
        new_win.geometry(w_var.get() + "x" + h_var.get())
        new_win.title(title_var.get()) 
        # 生成代码并显示
        code_str = "import tkinter as tk\n\n"
        code_str += "win = tk.Tk()\n"
        code_str += "win.geometry('" + w_var.get() + "x" + h_var.get()+ "')\n"
        code_str += "win.title('" + title_var.get() + "')\n\n"
        code_str += "win.mainloop()\n"
        codeText.delete(1.0,"end")
        codeText.insert("insert",code_str)
        has_Run = True
        new_win.mainloop()
    else:
        has_Run = False
        new_win.destroy()
        run_Window() # 自己调用自己是否可行？没有Goto啊
# 运行按钮
btnRun = tk.Button(win)
btnRun["text"] = "运行"
btnRun["width"] = 10
btnRun["height"] = 1
btnRun["command"] = run_Window
btnRun.place(x=220,y=10)
def close_Window():
    new_win.destroy()
# 停止按钮
btnRun = tk.Button(win)
btnRun["text"] = "停止"
btnRun["width"] = 10
btnRun["height"] = 1
btnRun["command"] = close_Window
btnRun.place(x=300,y=10)
# 代码区
codeText =tk.Text(win)
codeText["width"]=80
codeText["height"]=21
codeText.place(x=10,y=80)
win.mainloop()

改进：各个参数默认值+top\left值的支持

win.geometry("600x400+800+400")
win.title("tkWindow代码生成器")

txtTitle.place(x=60,y=10)
# 宽度x高度

labWH["text"] = "宽x高"
labWH.place(x=10,y=40)

txtW.place(x=60,y=40)
txtH = tk.Entry(win,textvariable = h_var)
txtH["width"] = 5 
txtH.insert(0,"300") #默认窗体高度
txtH.place(x=130,y=40)
# +top+left
labTL = tk.Label(win)
labTL["text"] = "顶+左"
labTL.place(x=170,y=40)
txtLeft = tk.Entry(win,textvariable = left_var)
txtLeft["width"] = 5 
txtLeft.insert(0,"600") #默认窗体Left值
txtLeft.place(x=260,y=40)
txtTop = tk.Entry(win,textvariable = top_var)

txtTop.place(x=330,y=40)

# 运行窗体实例
