tkinter.ttk.Progressbar:如何更改单杠的粗细 [英] tkinter.ttk.Progressbar: How to change thickness of a horizontal bar
问题描述
我在我的应用中使用 ttk.Progressbar
.我已经在网上搜索了答案,但无济于事.
I am using the ttk.Progressbar
in my app. I have scoured the net for an answer but no avail.
我有以下运行良好的代码.但是我想改变条的粗细.
I have the following code which is working well. But I want to change the thickness of the bar.
progressbar = ttk.Progressbar(myGui, orient=HORIZONTAL,
length=400, mode="determinate",
variable=value_progress,
)
progressbar.pack()
我希望长度仍然是 400,但是从条形图的顶部到底部,我希望将其减少到一半或不到一半.(可以这么说,我想要我的酒吧节食)
I want the length to still be 400, but from the top of the bar to the bottom, I wish to decrease that so its half or less then half. (I want my bar on a diet, so to say)
但我正在努力寻找解决方案.
But I am beating my head against the wall to figure out a solution.
安迪的想法?提前致谢.
Andy ideas? Thanks in advance.
推荐答案
ttk 进度条 似乎缺少 Python 中的宽度选项.
The ttk progress bar appears to lack the width option in Python.
使用变通方法(此处)解决 Tkinter 按钮的问题.由此,我已经能够创建一个有效的解决方案.
Using a work around (here) for an issue with a Tkinter Button. From this I have been able to create a working solution.
解决问题的关键是将进度条添加到window 在画布内.添加小部件时,在画布内使用窗口不会导致画布调整大小,这意味着我们可以控制进度条的宽度.
The key to solving the issue was to add the progress bar to a window inside the canvas. Using a window inside the canvas doesn't cause the canvas to resize when the widget is added which means we can control the width of the progress bar.
我已经创建了一些工作示例代码:
I have created some working example code:
from ttk import Progressbar
import Tkinter
class Example(Tkinter.Frame):
def __init__(self, parent):
Tkinter.Frame.__init__(self, parent)
self.parent = parent
self.initUI()
def initUI(self):
value_progress =50
self.parent.title("Progressbar Thingymawhatsit")
self.config(bg = '#F0F0F0')
self.pack(fill = Tkinter.BOTH, expand = 1)
#create canvas
canvas = Tkinter.Canvas(self, relief = Tkinter.FLAT, background = "#D2D2D2",
width = 400, height = 5)
progressbar = Progressbar(canvas, orient=Tkinter.HORIZONTAL,
length=400, mode="indeterminate",
variable=value_progress,
)
# The first 2 create window argvs control where the progress bar is placed
canvas.create_window(1, 1, anchor=Tkinter.NW, window=progressbar)
canvas.grid()
def main():
root = Tkinter.Tk()
root.geometry('500x50+10+50')
app = Example(root)
app.mainloop()
if __name__ == '__main__':
main()
所以总而言之,进度条大小相同,但您看不到它的一半!
So to sum up the progress bar is the same size but you just cant see half of it!
