如何打开Tkinter窗口(例如条目,文本......)并在打开它们时使它们显示在屏幕上而不是开始最小化? 我真的不知道如何开始...我有一些窗户,但它们被打开最小化。我在互联网上搜索,但没有发现可能相关的任何内容。我该怎么做 ? 在Windows上使用python(Python 3和Python 2) 感谢您的帮助!
编辑:现在我在评论中提到的问题是我必须强制显示窗口。但是当我这样做时,即使我使用一个函数将集中在之前,窗口也不会开始居中。
代码:
def center(toplevel):
toplevel.update_idletasks()
w = toplevel.winfo_screenwidth()
h = toplevel.winfo_screenheight()
size = tuple(int(_) for _ in toplevel.geometry().split('+')[0].split('x'))
x = w/2 - size[0]/2
y = h/2 - size[1]/2
toplevel.geometry("%dx%d+%d+%d" % (size + (x, y)))
def paste_func():
global text_box
text_box.insert(END, top.clipboard_get())
button_pressed()
def button_pressed(x=0):
# This function determines which button was pressed, and closes this menu/message box/etc...
global pressed
pressed = x
destroy_top()
def destroy_top():
# This function closes this menu/message box/etc...
global top
top.iconify()
top.withdraw()
top.quit()
def get_text():
global pressed
global top
global text_box
pressed = 0
top = Tk()
top.withdraw()
top.rowconfigure(0, weight=0)
top.columnconfigure(0, weight=0)
top.config(height=0, width=0)
top.protocol('WM_DELETE_WINDOW', lambda: button_pressed(-1))
text_box = Entry(top, width=50)
text_box.focus_set()
text_box.grid(row=0, column=0)
but = Button(top, text='Enter', command=button_pressed)
but.grid(row=0, column=1)
paste = Button(top, text='Paste', command=paste_func)
paste.grid(row=0, column=2)
top.deiconify()
text_box.focus_set()
top.after(0, top.focus_force())
center(top)
top.mainloop()
if pressed == -1:
exit()
return text_box.get('1.0', index2=END)
答案 0 :(得分:1)
window.focus_force()
method执行此操作:
强制输入焦点到窗口小部件。这是不礼貌的。最好等待窗口管理器为您提供焦点。另见下面的
.grab_set_global()
。
有时如果这不起作用,你可以手动强制它:
from Tkinter import *
window = Tk()
window.after(2000, window.focus_force)
window.mainloop()
有时你会有issues on Macs which can require some additional finagling,但这应该可以在其他地方正常工作(OP没有指明任何有关环境的信息)。
