label

问题 I would like to update a label once I press one of the buttons. Here is my code - I added a label (caled label1 ), now I have two issues: It presents some gibberish How do I update the label with text right when the user is pressing the Browse button? from tkinter import * import threading class Window(Frame): def __init__(self, master=None): Frame.__init__(self, master) self.master = master self.init_window() def init_window(self): self.var = IntVar() self.master.title("GUI") self.pack(fill

问题 In according with the TTK documentation, in my code, I tried to change the background color only for the TTK labes placed in readonly mode, but unfortunately it didn't work. I replicated the issue below: from tkinter import * from tkinter import ttk class MainWindow: def __init__(self): self.parent=Tk() self.parent.geometry("350x250") self.parent.title("Test") self.parent.configure(background="#f0f0f0") style=ttk.Style() # only the "foreground" option works, but the "background" one not. why?

问题 I can change color of all text in label, but I want to change color of one letter. Is that possible? I use tkiner and python 3.3. 回答1: No, it is not possible to change the color of one letter in a label. However, you can use a text widget instead of a label to color just a single character. You could also use a canvas widget. 来源： https://stackoverflow.com/questions/22071505/change-color-of-one-letter-in-label-python

问题 I have a plotly graph made in ggplot2. I am displaying the graphics using face_grid but the y axis is very long. Because of this not all the words on the y axis are visible. Is there a way to split the text into two lines such that the entire y axis is visible? majors.sub.HS<- majors.sub[, c(8:10, 66)] majors.sub.HS<-melt(majors.sub.HS, id.vars = "Major" ) majors.sub.HS$value[majors.sub.HS$value=="5- Highly Supported"] <- 5 majors.sub.HS$value[majors.sub.HS$value=="1- Not Supported"] <- 1

问题 Say I have a plot like this: library(ggplot2) dat <- data.frame(x = 1:10, y = 1:10) ggplot(dat, aes(x = x, y = y)) + geom_point() + xlab("Test label") Does ggplot2 allow for fixing the xlab positioning at a specific point? Say I wanted the label to appear centered at the point where x = 7 (rather than the default centering). 回答1: This isn't exactly what you want, but you can adjust the horizontal justification in the theme options. This is relative between 0 and 1, not tied to the data

问题 I am using JSON APOC plugin to create nodes from a JSON with lists in it, and I am trying to create nodes whose label is listed as an element in the list: { "pdf":[ { "docID": "docid1", "docLink": "/examplelink.pdf", "docType": "PDF" } ], "jpeg":[ { "docID": "docid20", "docLink": "/examplelink20.pdf", "docType": "JPEG" } ], ...,} And I want to both iterate through the doctypes (pdf, jpeg) and set the label as the docType property in the list. Right now I have to do separate blocks for each

问题 I'm trying to make a simple RPG where as you collect gold it will be showed in a label, but it doesn't!! Here is the code: def start(): Inv=Tk() gold = IntVar(value=78) EtkI2=Label(Inv, textvariable=gold).pack() I'm new to python and especially tkinter so I need help!!! 回答1: The only thing wrong with your code is that you aren't calling the mainloop method of the root window. Once you do that, your code works fine. Here's a slightly modified version that updates the value after 5 seconds:
