alignment

问题 Is it possible to specify alignment of parent class? for example something like (which does not compiled): template<size_t n> class Vector : public boost::array<double,n> __attribute__ ((aligned(16))) { thanks well, from comments I gather this is no good way to go. I think I will just stick to composition/alignment of private array 回答1: We don't need to request alignment on the derived class neither we can. The reason why we don't need is that it is enough to request alignment for the derived

问题 The implementation of std::vector that ships with Visual Studio 2010 and earlier versions has a well known particularity: the resize method has the following signature (C++03-compliant): void resize(size_type new_size, value_type value); instead of the C++11-compliant signature that's been used by the majority of other STL implementations (like gcc's STL or STLport) long before C++11: void resize(size_type new_size, const value_type& value); The problem with the first variant is that, in some

问题 I am using QTableView's checkbox flag of Qt::ItemIsUserCheckable to display a checkbox in a table cell. After reading some things on alignment in an attempt to center the checkbox within the cell, I am returning the Qt::AlignCenter as the TextAlignmentRole from the models data() function. QVariant ExampleModel::data(const QModelIndex &index, int role) const { if(!index.isValid()) return QVariant(); if (role == Qt::TextAlignmentRole) return Qt::AlignCenter | Qt::AlignVCenter; } This however is

问题 I'm designing a UI, and I found myself itching my head : how can I align a TextBox text and a label text, which are side by side. In design mode, it's easy, you move one with your mouse, a purple line appears and voila ! the alignment is good, but mine are code generated, so how can i align their contents ? Thank you ! Edit : Layout is something I can't use (I don't make the rules, my boss do..) 回答1: I like to use the FlowLayoutPanel (instead of the TableLayoutPanel ) for this purpose because

问题 I want my navigation bar to show two things in the middle. One them is going to be List name, and the other one will be name of users. User names will be placed under list name. What i have done so far is, i created two label and one superview programatically and set the titleView of navigationItem . override func viewDidLoad() { super.viewDidLoad() var rectForView = CGRect(x: 0, y: 0, width: 190, height: 176) var viewForTitle = UIView(frame: rectForView) var rectForNameLabel = CGRect(x: 0, y

问题 how do I make the list go beside each other (horizontally) instead of going down (vertically). Example: January (this is what I keep getting) S M T W T F S 1 2 3 4 5 ... January (this is what I wanted to get) S M T W T F S 1 2 3 4 5 6 7 8 9 ... Thanks any help would be appreciated, I'm new at this and I can't figure it out. :) 回答1: Use : System.out.print("Value"); instead of : System.out.println("Value"); And don't forget to add a System.out.println(""); at the end to flush the buffer. 来源：

问题 How does one set the alignment of text within a chart legend object? I've tried using: myChartName.Legends["mySeriesName"].Alignment = stringAlignment.Near With no effect. I've also tried to create custom legend items, again resulting in no effect. Text is ALWAYS centered (along with the series marker) in the legend "box". The only text I have been able to align is the title, but I don't need titles in my application. My research to date says the legend object is basically a table with (by
