[英]Got blurred image on resizing image as label in tkinter window in python
[英]Label is resizing incorrectly tkinter
這是我的第一篇文章,所以對我來說很簡單:)我有一個簡單的python 2.7腳本,它使用overrideredirect(1)
創建了一個窗口。 一切都很好,我添加的畫布也可以工作,但是當我添加標簽並應用其高度和寬度時,它在兩個軸上都會嚴重伸長。 標題欄和退出標簽都會發生這種情況。 我想讓它們變薄,但不能使用浮子。 有什么想法嗎? 這是我的代碼:
from Tkinter import *
from math import *
class Main():
def __init__(self):
# Create a basic tkinter window
self.root = Tk()
self.canvas = Canvas(self.root, width=700, height=500)
self.canvas.pack()
# Start function that creates labels
self.initiate()
# Make the window frameless
self.root.overrideredirect(1)
self.root.mainloop()
def initiate(self):
# Create a single black bar across the top of the window
# My issue is here. I apply the height of 1, and it displays in the tkinter window of a height more like 10-20.
# I think it has somthing to do with overrideredirect, but i dont know what it is, i have never used it before.
self.titlebar = Label(self.canvas, width=700, height=1,
bg='black')
self.titlebar.place(x=0, y=0)
# This and the other functions make the window move when you drag the titlebar. It is a replacement for the normal title bar i removed with overrideredirect.
self.titlebar.bind("<ButtonPress-1>", self.StartMove)
self.titlebar.bind("<ButtonRelease-1>", self.StopMove)
self.titlebar.bind("<B1-Motion>", self.OnMotion)
# Create a quit button in top left corner of window
self.quit = Label(self.canvas, width=1, height=1, bg='grey')
self.quit.place(x=0, y=0)
self.quit.bind("<Button-1>", lambda event: self.root.destroy())
def StartMove(self, event):
self.x = event.x
self.y = event.y
def StopMove(self, event):
self.x = None
self.y = None
def OnMotion(self, event):
deltax = event.x - self.x
deltay = event.y - self.y
x = self.root.winfo_x() + deltax
y = self.root.winfo_y() + deltay
self.root.geometry("+%s+%s" % (x, y))
Main()
除非標簽上有圖像,否則寬度和高度將根據標簽所使用的字體表示多個平均大小的字符。 寬度700和高度1可能會導致寬度為6000-7000像素,高度為15-20像素。
如果要創建邊框,建議使用框架,因為其寬度和高度參數以像素為單位。
