user-interface

问题 I want to prompt user to choose between yes and no in the middle of a function and then continue the function accordingly. How is it possible?

问题 I want to design a graphical user interface in MATLAB that can read data continuously using the MATLAB's object linking and embedding for process control (OPC) toolbox. How can I implement this? I have designed the graphical user interface, but I'm not able to read the data into the graphical user interface. 回答1: Take a look at this submission of mine from the MATLAB Central File Exchange. It gives a full example of how to read and write data from an OPC server, and how to create and compile

问题 Unfortunately, I have two loops. that's why my code makes the first loop run and only when it is finished, it makes the second loop run. But I want the gui to show the data simultaneously: in the hAxes and in the loading1. How can I make it? hFigure = figure('units','pixels','position',[300 300 424 470],'menubar','none',...

问题 I want my panel to fit the frame when I show/hide fields. How could I notify to the parent frame to revalidate? I thought about pass the frame to my panel's constructor, but I think may have a way this is already done.

问题 it is my first time using tkinter. I have an entry box on the first window, and I created radio buttons on different windows. The problem is that they are already selected before I click any of them. How can I change all buttons to be deselected? I am not sure if my codes are right or not. from tkinter import * from tkinter import messagebox class SortingHat: # Constructor def __init__(self): # Create main window self.__main_window = Tk() self.__main_window.geometry('300x200') self.__main

问题 I'm trying to create a screen "curtain" which blocks parts of the screen except for the mouse cursor's vicinity. On windows, using root.wm_attributes("-topmost", "true") keeps the window on top, even if I focus on another app, perfectly. However, upon running the code on MacOS, if the focus for the window is lost, it will not keep itself on topmost. What would be the MacOS equivalent to -topmost window manager attribute which will always keep the window on top, regardless of focus? import
