问题 I'm having an issue. I've implemented a PhaseListener, which is meant to add a style class to any UIInput components in the tree that have messages attached to them, and removes the style class if it doesn't have any messages attached to them. The PhaseListener runs in the RENDER_RESPONSE phase, and does it's work in both the beforePhase and afterPhase methods while debugging. While debugging, I found that beforePhase doesn't have access to the full component tree, but afterPhase does. Any

问题 According to specification: If the member is an array of scalars or vectors, the base alignment + * and array stride are set to match the base alignment of a single + * array element, according to rules (1), (2), and (3), and rounded up + * to the base alignment of a vec4. The array may have padding at the + * end; the base offset of the member following the array is rounded up + * to the next multiple of the base alignment. Does this mean that if I had an array of size 3 of a (float)vec3,

问题 I am trying to make a game and I am trying to render a lot of text. When the text renders, the rest of the text goes off the screen.

问题 So I had performance issues with my libgdx project and I tracked it down to the map rendering. I isolated the issue by creating an empty project and do as little as possible, just the map rendering. This is the code I came up with: The Desktop start up project class: package com.me.test; import com.badlogic.gdx.backends.lwjgl.LwjglApplication; import com.badlogic.gdx.backends.lwjgl.LwjglApplicationConfiguration; public class Main { public static void main(String[] args) {

问题 I use Jvectormap into my Rails 3 app. When I click on it, I want to hide the map and visualize a partial with information about the selected country. I handle the map click and I send a GET req to the server. users.js.coffee.erb $ -> $("#world-map").vectorMap onRegionClick: (event, code) -> $('#world-map').hide(1000) $.get('/users/statistics', {code: code}); $('#statistics').show(1000) users_controller.rb def statistics @country = Country.find_by_two_letter_code((params[:code]).downcase)

问题 This question already has answers here : Does the syntax (whitespace) of a javascript function return affect the result? [duplicate] (3 answers) Why doesn't a Javascript return statement work when the return value is on a new line? (3 answers) Closed 2 years ago .

Example: this works: render() { return ( <View

问题 I have to compare some values in data and display weekly trends. I want to show if a value has increased from last week. I have created an rmarkdown report to do it. An example code is shown below, which works perfectly when output: html_document but output is messed up when using output: word_document --- title: "trials" author: "Foo Bar" date: "15 December 2016" output: word_document --- ```{r setup, include=FALSE} knitr::opts_chunk$set(echo = TRUE) ``` ```{r cars, echo=FALSE, cache=FALSE,

问题 The following code allows to create sliderInput control widgets for selected number of variables. For the brevity, filtering code as per sliderInput range is removed. So, please neglect what is being seen in the data table. sliderInput widgets pop up whenever a new variable selected or added to the list of already existing variables. However, these widgets do not retain the previously selected values, i.e., let's say you selected sepal.length , modified slider range, and then selected sepal
