size

问题 I want determine the size of a web page, and so, if it is greater than a number (eg.:5MB), I will download it or not. Can I have this information? 回答1: You can do a decent approximation with: HttpURLConnection content = (HttpURLConnection) new URL("www.example.com").openConnection(); System.out.println(content.getContentLength()); However, this will only tell you the length of the specific resource you're requesting (e.g. the HTML at the base of the URL). You will also need to go through the

问题 I am having issues setting the calendar font sizes to be smaller. I have changed setting a container div font size, no effect. I have also changed the fullCalender.css font from 1em to 0.5em and to a px size but the calendar text stays the same. 回答1: This is quite the blast from the past, but I originally found this looking for a solution. I just wanted to change the font size of the elements in the table (date headers, time sidebar). The following worked for me: th.ui-widget-header { font

问题 I have a JFrame that I've set to a certain size, using setBounds. However, that makes the window, including the borders, that size (which in hindsight makes complete sense). But what I want is for the size of the window it be, say, 800x600 plus the borders. This is important because I'm drawing to a Graphics object from the BufferStategy from the JFrame, but I've been drawing underneath the title bar when using a y value of less than about 20. I imagine different OSs (or even different OS

问题 I've got the following: struct A { int a[4]; }; struct B { int x, y; }; int main() { std::cout << std::boolalpha << "std::atomic<A> is lock free? " << std::atomic<A>{}.is_lock_free() << '\n' << "std::atomic<B> is lock free? " << std::atomic<B>{}.is_lock_free() << '\n'; } It compiles and works well, but if I raise the size of A: struct A { int a[5]; }; struct B { int x, y; }; int main() { std::cout << std::boolalpha << "std::atomic<A> is lock free? " << std::atomic<A>{}.is_lock_free() << '\n'

问题 If got a very basic layout, with a header, content container and a footer. What i need done, is to make my content container size up, so that the whole layout will fit on the screen. (unless the text in the content container extends this of course). I've tried assigning a height 100% value to my body, and from there assigning my content containers height to 100% aswell, but that results in making my content container size up to the height of the full screen. Before that i had the height on

问题 I have a crash which only occurs on 4S (not on 3GS). I am doubting its because of @2x. Basically I get raw bytes of image and manipulate. Here's the question I have. I load a image as mentioned in the sample code below. At the end, uiWidth should be 2000 and cgwidth should be 2000. Correct? (Would it still be true if image is loaded from camera rolls? Or its autoscaling and uiWidth will be 4000?) //test.jpg is 2000x 1500 pixels. NSString *fileName = [[NSBundle mainBundle] pathForResource:@

问题 EDIT: Ok, so I approached the problem the wrong way: to do what I intended to, I just needed to check if there was an overflow. Here is the code (if it can help anyone): <script type="text/javascript"> function textfit(){ var spans = document.body.getElementsByTagName("span"); for(var i = 0, l = spans.length; i < l; i++){ var span = spans[i]; var font = window.getComputedStyle(span, null).getPropertyValue('font-size'); var fontSize = parseInt(font); do { span.style.fontSize = (fontSize --) +

问题 Good evening, I'd like to know how to get the size of a JComponent after it's been laid out with a LayoutManager. I've read that this is possible, if you just call dolayout(), validate(), or setVisible() beforehand. However, I can't get it to work in my code. The reason I'd like to know this is to only add as many components as will fit in the frame's set size, while not knowing the size of the components beforehand. Calling validate() doesn't set the size of the components in this code

问题 The command tries to sum up the sizes: find . -iname "*.dmg" -exec du -sh '{}' \; 3&> /dev/null | awk '{print $1}' | summming_up_program??? Can you find a simpler solution? Ubuntu Solution. Thanks for the Awk-end to Ayman. find . -iname "*.dmg" -printf '%b\n' | awk 'BEGIN { s = 0 } {s += $1 } END { print "%dMB", s / 2^20 }' 回答1: find . -iname '*.dmg' -exec stat -f '%z' '{}' \; | awk 'BEGIN { s = 0 } {s += $1 } END { print s }' stat is used to obtain the size of a file. awk is used to sum all

问题 I really need help for this questions, I search everywhere but can't seem to find an answer. I have a window with the height set to 66. In my code behind I have a button on the bottom of the the window. when the user clicks this button(this.height = 400), the size of the window is to grow from bottom up. but it grows from left top corner. please help :( 回答1: I think you need to change how the controls are anchored in the window. They are going to default to anchoring to the top left, so when
