iOS - Smooth Color Change Transition/Animation

由 安稳与你 提交于 2021-02-17 21:12:08
问题 I want to have a smooth color transition that goes across the entire spectrum (i.e. red, blue, green, yellow, orange, etc.) Also want to be able to have smooth transitions of colors in specific spectrum (i.e. all reds). Are there any simple algorithms/recursive functions/formulas that can help simplify this process? 回答1: One possible way of doing it is apply background color animation on view's layer. Now to pass through entire spectrum you have to work on combinations of three colors. The

JPanel not changing on JFrame

由 徘徊边缘 提交于 2021-02-17 05:43:25
问题 The idea is to have one "global" JFrame which I can then add/remove JPanels as needed to make a smooth flowing application. Currently, when I try changing from the first JPanel to the second, the second won't display. My code is below: Handler (class to run the app): package com.example.Startup; import com.example.Global.Global_Frame; public class Handler { public Handler() { gf = new Global_Frame(); gf.getAccNum(); gf.setVisible(true); } public static void main(String[] args) { new Handler()

What is the CSS transform:translate() property ultimately for?

问题 In CSS3, animations were introduced under the various vendor prefixes, with the transition properties. Now, at-least in pure CSS there are two ways to make an element change position. Setting the element's position as absolute and fiddle with left: right: top: and bottom: Using -vendor-transform:translate(X,Y,Z) Now, strictly on the point of transform:translate() , aside from one's ability to use translateZ() , the only difference between them is that the latter is not a reported value; other

CSS3 multiple transitions reversed animation

由 谁都会走 提交于 2020-08-27 22:30:47
问题 I have a div I'm trying to animate with CSS. div { width:100px; height:50px; -moz-transition: width: 1s, height: 1s 1s; } div:hover { width:400px; height:400px; } It works as I want when I hover; the width is first animated, followed by the height after a 1 second delay. But when I hover off the div, I would like it to do the same animations, but in reversed order; height first, then width. Is there any way to achieve this using only CSS? 回答1: You can just add -moz-transition to :hover too:

iOS Swift: How to recreate a Photos App UICollectionView Layout

由 微笑、不失礼 提交于 2020-02-20 11:23:47
问题 I am wondering for quiet a while now how to create the iOS Photos App layout. How can I make it so it looks like zooming in to a collection while at the same time the navigation bar shows a back button? Is it a new view controller which gets pushed onto a UINavigationController? And if so, how exactly do they manage to match the tiles while expanding. Is there maybe even a 3rd party library which lets me easily recreate such a layout? Hope you can help me to understand the concept of how this

Python3标准库：enum枚举

由 瘦欲@ 提交于 2020-02-19 17:46:10
1. enum枚举 枚举是一组符号名称（枚举成员）的集合，枚举成员应该是唯一的、不可变的。在枚举中，可以对成员进行恒等比较，并且枚举本身是可迭代的。 1.1 创建枚举 可以使用class语法派生Enum并增加描述值的类属性来定义一个新枚举。 import enum class BugStatus(enum.Enum): new = 7 incomplete = 6 invalid = 5 wont_fix = 4 in_progress = 3 fix_committed = 2 fix_released = 1 print('\nMember name: {}'.format(BugStatus.wont_fix.name)) print('Member value: {}'.format(BugStatus.wont_fix.value)) 解析这个类时，Enum的成员会被转换为实例。每个实例有一个对应成员名的name属性，另外有一个value属性，对应为类定义中的名所赋的值。 1.2 迭代 迭代处理enum类会产生枚举的各个成员。 import enum class BugStatus(enum.Enum): new = 7 incomplete = 6 invalid = 5 wont_fix = 4 in_progress = 3 fix_committed = 2
