问题 I previously posted a question here about aligned access during pointer casting. As a summary, it's better not to use unaligned access to be fully portable because some architecture may throw an exception, or the performance may get quite slower compared to aligned access. However, there are cases that I want to use one-byte alignment, e.g., during transferring network data, I don't want adding extra padding inside structure. So usually what's done here is: #pragma pack (push, 1) struct

问题 I am working on HTML email and trying to center a green TD in a white TR so that there's a 20px white margin on the left and right of the green box. I tried setting TD width for the green portion and setting margin 0 auto but the green just expands to the width of the TR. Tried putting in 2 more TDs to push the green TD into the center and that didn't work either. Including the code snippet, am having trouble with the TR that has #a6d971. <table cellspacing="0" cellpadding="0" border="0"

问题 Given a point such as (0, 0, 0) and a vector like (x, y, z). What is the easiest way to align the negative Z-axis centered at (0, 0, 0) to point in the direction of this vector? Examples using OpenGL would be welcome, but not neccessary. 回答1: There's lots of different ways to rotate a coordinate-frame to point in a given direction; they'll all leave the z-axis pointed in the direction you want, but with variations in how the x- and y-axes are oriented. The following gets you the shortest

问题 In my GUI application, I have several JPanels that are instantiated at various points during the running of my program, and certain actions will cause one of them to be displayed in a scroll pane: mViewport.setViewportView(currentPanel); The trouble is, that my panels are done using Grid Bag Layouts, and the behaviour of that is to center itself within the JScrollPane it is inside of. This make the GUI look weird. Anyone know of a way to force a grid bag layout panel to top-left align? Thanks

问题 I use stargazer package in my automated rmarkdown pdf documents to make nice looking tables. Stargazer places its tables in the center of the page, by default. How can I let stargazer generate latex code that aligns the table to the left? here is an example of what I mean: library(stargazer) data_object <- structure(list(test = structure(c(1L, 1L, 2L, 2L), .Label = c("test1", "test2"), class = "factor"), test2 = structure(1:4, .Label = c("1", "2", "3", "4"), class = "factor")), .Names = c(

问题 I have a GUI with big buttons and wouls like to align the text in the button to the top, all I found is "horizontal alignment" property. Thanks... 回答1: You need to access the underlying Java Swing component (I am using FINDJOBJ function): figure('Menubar','none', 'Position',[200 200 300 200]) h = uicontrol('Style','pushbutton', 'String','click', ... 'Units','normalized', 'Position',[0.3 0.3 0.5 0.5]); jh = findjobj(h); jh.setVerticalAlignment( javax.swing.AbstractButton.BOTTOM ); 回答2: I'm
