Getting the size of text without using the boundingBox function in Raphael javascript library

由 早过忘川 提交于 2019-12-01 01:09:26
I am trying to create some buttons with text in javascript using the Rahpael library. I would like to know the size of the styled text, before drawing to avoid that so I can create proper background (the button). Also I would like to avoid drawing the text outside of the canvas/paper (the position of the text is the position of its center). I can use Raphaels getBBox() method, but I have to create (draw) the text in first place to do this. So I draw text to get the size to be able to draw it on the right position. This is ugly. So I am searching for some general method to estimate the metrics

How to find Object's size (including contained objects)

由 只愿长相守 提交于 2019-12-01 00:53:22
问题 I want to estimate the size taken up by an object. To get the object's size I can just use To do so I might use Instrumentation.getObjectSize(myObject) , but this will give me a "shallow" size. I want to get the size of the Object, including the sizes of the objects it references. My thought is that I need to get the size of the object, then go through all the object's fields that are not static or primitives and get the size for the objects that they point to and do this recursively. Of

JFrame : Getting actual content size

由 此生再无相见时 提交于 2019-12-01 00:48:54
问题 I have created a JFrame, and attempting to get it's size is giving an incorrect result, compared to what I expect. I have determined that it is including the operating system borders around the edges, and the title bar. How can I get/set the real size which I have available for rendering? 回答1: The size you are getting is the size of the content and the size of the insets. If you use Jcomponent.getInsets(), you can find the size of the content with simple subtraction. 回答2: Your question is

How does “sizeof” work in this helper for determining array size?

由 六月ゝ 毕业季﹏ 提交于 2019-12-01 00:11:50
I've found this article that brings up the following template and a macro for getting array size: template<typename Type, size_t Size> char ( &ArraySizeHelper(Type( &Array )[Size]) )[Size]; #define _countof(Array) sizeof(ArraySizeHelper(Array)) and I find the following part totally unclear. sizeof is applied to a function declaration. I'd expect the result to be "size of function pointer". Why does it obtain "size of return value" instead? template<typename Type, size_t Size> char (&ArraySizeHelper(Type(&Array)[Size]))[Size]; #define _countof(Array) sizeof(ArraySizeHelper(Array)) sizeof is

Nvarchar or varchar what is better use multiply of 2 or rounded full numbers?

由 老子叫甜甜 提交于 2019-11-30 23:09:22
问题 My question is what is better to use in generating columns in SQL. Should the size of nvarchar (varchar) be multiply of 2 (32, 64, 128) or it's doesn't matter and we can use fully numbers example '100', '50' ? Thank You very much for answers with reasons Greeting's to all 回答1: Doesn't make any difference. Use the size appropiate for your data. For instance SQL Server, if you look at the Anatomy of a Record you'll see that your size translates into record offsets that are dependent on the

I need very big array length(size) in C#

public double[] result = new double[ ??? ]; I am storing results and total number of the results are bigger than the 2,147,483,647 which is max int32. I tried biginteger, ulong etc. but all of them gave me errors. How can I extend the size of the array that can store > 50,147,483,647 results (double) inside it? Thanks... An array of 2,147,483,648 double s will occupy 16GB of memory. For some people, that's not a big deal. I've got servers that won't even bother to hit the page file if I allocate a few of those arrays. Doesn't mean it's a good idea. When you are dealing with huge amounts of

Android: How to change the Size of the RadioButton

由 泄露秘密 提交于 2019-11-30 22:25:13
问题 I have many RadioButton s in my app. The RadioButtons are too big for me. Is there any way to make them smaller? 回答1: Can't be done, the radio button is a built-in control component and as such its size is fixed. 回答2: One quick hacky solution is to scale the button down: <RadioButton android:scaleX="0.5" android:scaleY="0.5" /> This works great for going smaller. For going larger, this tends to cause some clipping from the container View, so you'll likely have to hardcode the height/width of

Whats the size of an SQL Int(N)?

由 不羁的心 提交于 2019-11-30 21:36:16
问题 Simple question. I have tried searching on Google and after about 6 searches, I figured it would be faster here. How big is an int in SQL? -- table creation statement. intcolumn INT(N) NOT NULL, -- more table creation statement. How big is that INT(N) element? What's its range? Is it 2^N or is it N Bytes long? (2 ^ 8N)? Or even something else I have no idea about? 回答1: It depends on the database. MySQL has an extension where INT(N) means an INT with a display width of 4 decimal digits. This

UISplitView new slide-in popover becomes fullscreen after memory warning in iOS 5.1

由 岁酱吖の 提交于 2019-11-30 21:28:13
I'm quite new here. I have a problem with the new iOS 5.1 slide-in popover in UISplitView. (Before 5.1 the master view controller was presented in a popover, but now it simply slides in form the left.) When my device is in portrait mode and it receives a memory warning, the master view controller unloads; and when I press the toolbar button to slide in the master view, it loads again. However after the memory warning it is presented in fullscreen and not only the size of the original master view. (When I rotate the device to landscape and back to portrait, it gets its correct size back.)

350GB SVN repo creates atleast 1MB revision for even a simplest task like branch/tag

由 末鹿安然 提交于 2019-11-30 21:19:52
This all started when I noticed that my repository size is increasing at a daily rate of 1GB. I did a simple test. Created a branch/tag of an existing folder that had a size of 35KB. I took note of revision number and went to $REPO/db/revs/<K-rev>/rev-number/ and checked the size of the revision. It was 1 mega byte. That sounds fishy. Any ideas on what might be wrong here. My repo is about 350GB in size with about 600,000 revisions. P.S. I have already started a rebuild of the whole repository to see if that makes any difference but it will probably take days to complete. Posted same question
