alignment

问题 I have an array which is used as the underlying memory of an object of type T : char memory[sizeof T]; . . . new(memory) T(whatever); How can I make sure memory is aligned correctly for T objects? In C++0x I could just say: alignas(T) char memory[sizeof T]; but Visual Studio 2010 does not support that particular feature yet. 回答1: The usual (portable) solution is to put the memory declaration in a union with whatever built-in type in T requires the most alignment. The simplest way would be to

问题 I am using Table Layout to display data as shown below. What i want to do ? I want the Text in the second column to be aligned to the left and the text should wrap and be displayed in the next line and over flow as you see in the image. Code: <TableLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/tableLayout1" android:layout_width="match_parent" android:layout_height="match_parent" > <TableRow android:id="@+id/tableRow2" android:layout_width="match_parent"

问题 This is probably best explained with an example. I have the following table, where the "A" cell spans two rows, and the "B" cell spans two columns. \begin{table}[htdp] \begin{tabular}{l|r|r} \multirow{2}{*}{A} & \multicolumn{2}{c}{B} \\ & B1 & B2 \\ a & b1 & b2 \\ a & b1 & b2 \\ \end{tabular} \end{table} _ _ _ _ _ _ _ _ _ _ _ _ |A |_ _ _ _B_ _ _ _| |_ _ _ _|_ _B1_ |_ _B2_ | |a | b1| b2| |a | b1| b2| |a | b1| b2| |_ _ _ _| _ _ _ |_ _ _ _| I would like to center the text in the "A" cell, only.

问题 How the UILabel can be aligned from bottom. Let say, my label can hold three line of text.If the input text is single line, then this line should come bottom of the label.Please refer the below image for better understanding.

Please suggest your ideas. Thank you. 回答1: Here are two ways of doing that... 1. First set

问题 So here's my HTML: ... <div class="header"> <div class="left"> </div> <div class="center"> <img class="logo" src="linktomyimage.com/image.png" /> </div> <div class="right"> </div> </div> <!-- And the desired result is: --> [ [LEFT] [CENTER] [RIGHT] ] The only CSS I have is: * { margin: 0px; } img.logo { display: block; margin-left: auto; margin-right: auto; } I really need help to align the three divs on the whole page. Also div.center must have the same size as the image, aka width - 800px

问题 I'm programming a jquery slider right now and I have the width set to 100% and I want it to align to the bottom of the window no matter how the window is resized. I have found ways to make it stick to the bottom the whole time you scroll down, but I do not want this. I want to be able to scroll below this slider to get to more content. This website shows the kind of function that I am looking for. I tried to inspect it with firebug to find the part how it was happening but I couldnt figure it

问题 Basically I have a JTable , and this JTabel will have a product in one cell, and then in the cell directly below it the cost. The product name should be aligned to the left. The product cost should be aligned to the right. I don't actually care what the alignment of other cells in each row is. So I need to set the alignment of either individual cells, or individual rows. I've found ways to set the alignment of the table, and ways to set the alignment of the columns, but never the rows
