问题 When I create new objects with insertUI in a reactive way, all the observers that I create work perfectly fine, as you can see in the following dummy code: library(shiny) # Define the UI ui <- fluidPage( actionButton("adder", "Add"), tags$div(id = 'placeholder') ) # Define the server code server <- function(input, output) { rv <- reactiveValues() rv$counter <- 0 observeEvent(input$adder,{ rv$counter <- rv$counter + 1 add <- sprintf("%03d",rv$counter) filterId <- paste0('adder_', add) divId <-

问题 How can I be able to create dynamic equal-sized squares inside a fixed big square? size should be according to number of squares. 回答1: This will be the most universal solution. Using CSS grid whit countable column and rows, according to the sum of children element. JS explanation: grid.children.length - counts children of grid div. Math.sqrt(grid.children.length) - returns the square root of a children length. Math.ceil(Math.sqrt(grid.children.length)) - rounds a number up to the next largest

问题 After much googling I'm aware that I need to use self.setWindowFlags(QtCore.Qt.FramelessWindowHint) to generate a frameless window, and some variation of the co-ordinates (0,0) to place it in the upper left corner of the screen. The problem I'm having is that everywhere that I've tried using this code, it generates errors, even in my sparse existing code: from PyQt4 import QtCore, QtGui from ui.mainwindow import MainWindow if __name__ == "__main__": import sys app = QtGui.QApplication(sys

问题 I am trying to figure out if it is possible to use a Window 10 docker image in a docker container with full Desktop GUI functionality. Information has been a bit all over the place on this topic since it is a fairly new concept. The hope is to use Windows 10 docker images with fully functional Desktop GUI available to run Automated Functional GUI tests. 来源： https://stackoverflow.com/questions/60554738/is-it-possible-to-run-windows-10-docker-image-with-full-gui-desktop-functionalit
