问题 In my app I display a popup using JPopupMenu . I want to run some code when this popup closes (either directly, programmatically or when escape key is pressed). For windows I can attach a WindowListener but JPopupMenu doesn't have any corresponding feature, and SwingUtilities.windowForComponent returns the root window of the app. How do I implement this? 回答1: How about adding a PopupMenuListener to it? Something like: jpopMenu.addPopupMenuListener(new PopupMenuListener { public void

问题 I wanted to place three separate red boxes over a transparent window. This first method I used relied on a picture of three rectangular boxes with a transparent background ( because I'm new to tkinter) and then place it over the transparent window. from PIL import ImageTk, PngImagePlugin from tkinter import * import tkinter as tkr app = tkr.Tk() app.title("AI Cashier") app.geometry("1366x768") app.wm_attributes("-alpha", 0.1) my_img = ImageTk.PhotoImage(PngImagePlugin.Image.open("Capture1.png

问题 I have an app for which I allow the user to enable 'open at login' via a preference using a launcher app (see https://en.atjason.com/Cocoa/SwiftCocoa_Auto%20Launch%20at%20Login.html). However, when I check the box to enable it, the launcher app opens another instance of my app. 回答1: I found a bundle key that can be used for this: LSMultipleInstancesProhibited . When set to YES , another instance cannot be opened. Potential downside is that it also prohibits another logged-in user from opening

问题 I see this thing with Alert dialog's buttons touching (there is no space between them). This happens regardless of the theme being used.. Code: builder.setTitle(R.string.sign_in_title); builder.setCancelable(false) .setPositiveButton(R.string.sign_in, (dialog, id) -> { //Todo }) .setNegativeButton(R.string.cancel, (dialog, id) -> dialog.cancel()); builder.create().show(); App theme inherits: <style name="AppTheme" parent="Theme.MaterialComponents.Light.NoActionBar"> I tried to build a minimum

问题 I am doing some ui automation, and I am able to store screen touches using getevent, but when I try to send this using sendevent, it takes a really long time, making it hard to actually replay the inputs. I have already trying loading the script onto the device and running the script locally on the device (a script with a bunch of sendevent commands). But this only imporved this slightly. Is there some other way to inject these commands in a quicker way? 回答1: The handler for touch is
