问题 How can I add padding to a tkinter window, without tkinter centering the widget? I tried: self.canvas_l = Label(self.master, text="choose a color:", font="helvetica 12") self.canvas_l.grid(row=9, column=1, sticky=S, ipady=30) and self.canvas_l = Label(self.master, text="choose a color:", font="helvetica 12") self.canvas_l.grid(row=9, column=1, rowspan=2, sticky=S, pady=30) I want 30px padding only on the top of the label. 回答1: The padding options padx and pady of the grid and pack methods can

CSS3 盒子模型

CSS中有一种基础设计模式叫盒模型,盒模型定义了Web页面中的元素中如何来解析。CSS中每一个元素都是一个盒模型,包括html和body标签元素。在盒模型中主要包括width、height、border、background、padding和margin这些属性,而且他们之间的层次关系可以相互影响。 从图中可以看出padding属性和content属性层叠background-image属性,层叠background-color属性,这个是存在的,它们四者之间构成了Z轴(垂直屏幕的坐标)多重层叠关系。但是border属性与margin属性、padding属性三者之间应该是平面上的并级关系,并不能构成Z轴的层叠关系。 box-sizing: 在CSS中盒模型被分为两种,第一种是w3c的标准模型,另一种是IE的传统模型,它们相同之处都是对元素计算尺寸的模型,具体说不是对元素的width、height、padding和border以及元素实际尺寸的计算关系,它们不同之处是两者的计算方法不一致,原则上来说盒模型是分得很细的,这里所看到的主要是外盒模型和内盒模型,如下面计算公式所示: W3C标准盒模型 外盒尺寸计算(元素空间尺寸) element空间高度=内容高度+内距+边框+外距 element空间宽度=内容宽度+内距+边框+外距 内盒尺寸计算(元素大小) element高度=内容高度

Padding in structures in C

孤者浪人 提交于 2019-11-26 16:04:00
This is an interview question. Till now, I used to think such questions were purely compiler dependent and shouldn't worry me, but now, I am rather curious about it. Suppose you are given two structures as: struct A { int* a; char b; } and , struct B { char a; int* b; } So which one would you prefer and why? My answer went like this (though I was somewhat shooting in the dark) that the first structure should be preferred since the compiler allocates space for a structure in some multiples of the word size (which is the size of the pointer - 4 bytes on 32 bit machines and 8 bytes on 64 bit ones

How to adjust gutter in Bootstrap 3 grid system?

不打扰是莪最后的温柔 提交于 2019-11-26 15:48:01
问题 The new Bootstrap 3 grid system is great. It's more powerful for responsive design at all screen sizes, and much easier for nested. But I have one issue I could not figure out. How do I add precise gap between the columns? Say I have container 960px, 3 columns at 310px and 2 gutters at 15px in between 3 columns. How do I do that? 回答1: You could create a CSS class for this and apply it to your columns. Since the gutter (spacing between columns) is controlled by padding in Bootstrap 3, adjust

Why does the size of a class depends on the order of the member declaration? and How?

冷暖自知 提交于 2019-11-26 15:47:34
问题 Someone explain me how does the order of the member declaration inside a class determines the size of that class. For Example : class temp { public: int i; short s; char c; }; The size of above class is 8 bytes. But when the order of the member declaration is changed as below class temp { public: char c; int i; short s; }; then the size of class is 12 bytes. How? 回答1: The reason behind above behavior is data structure alignment and padding . Basically if you are creating a 4 byte variable e.g

Add leading zeroes/0&#39;s to existing Excel values to certain length

99封情书 提交于 2019-11-26 15:40:47
There are many, many questions and quality answers on SO regarding how to prevent leading zeroes from getting stripped when importing to or exporting from Excel. However, I already have a spreadsheet that has values in it that were truncated as numbers when, in fact, they should have been handled as strings. I need to clean up the data and add the leading zeros back in. There is a field that should be four characters with lead zeros padding out the string to four characters. However: "23" should be "0023", "245" should be "0245", and "3829" should remain "3829" Question: Is there an Excel

1、线性布局 LinearLayout: 线性布局是所有布局中最常用的类之一,也是RadioGroup, TabWidget, TableLayout, TableRow, ZoomControls类的父类。LinearLayout可以让它的子元素垂直或水平的方式排成一行(不设置方向的时候默认按照垂直方向排列)。 举个例子: 1 <? xml version="1.0" encoding="utf-8" ?> 2 < LinearLayout xmlns:android ="http://schemas.android.com/apk/res/android" 3 android:orientation ="vertical" 4 android:layout_width ="fill_parent" 5 android:layout_height ="wrap_content" 6 > 7 <!-- 8 android:id —— 为控件指定相应的ID 9 android:text —— 指定控件当中显示的文字,需要注意的是,这里尽量使用strings.xml文件当中的字符串 10 android:grivity —— 指定控件的基本位置,比如说居中,居右等位置 11 android:textSize —— 指定控件当中字体的大小 12 android:background ——
