detect

问题 Is it possible to detect a mouse click anywhere on a screen, outside of my application? I have written an application to do this in C#, but would like to write a version of this in Java so that it can be run on several platforms. It looks like I can get the co-ordinates of the mouse at any time with java.awt.MouseInfo.getPointerInfo() but I am not sure as to how to listen for a mouse click. In C# I used GetAsyncKeyState to detect whether the mouse button was clicked, but obviously I cannot

问题 This question already has answers here : How to trigger event when a variable's value is changed? (4 answers) Closed 3 years ago . I've been searching this for a while and I didn't found anything for my problem. I have a integer: private static int kills = 0; I want a function to run when that variable changes. Like, it is 0 now. If it changes to 2, I want a function like OnVarChange that will be called, and that function OnVarChange will return the amount that was changed. In this case 2-0=2

问题 I have a string where I know that the degree symbol (°) is represented by the byte 63 (3F). Each character is represented by a single byte. How can I find the character encoding used ? 回答1: Almost all 8-bit encodings in modern times coincide with ASCII in the ASCII range, so byte 3F hexadecimal is the question mark “?”. As Sebtm’s comment suggests, this might result from character-level data error. E.g., some software that is limited to ASCII could turn all other bytes to “?” – not a good

问题 So I know how to change the css depending on the resolution via javascript. How would one go about 'cropping' an image depending on the screen resolution? 回答1: Well you can get the screen details from window.screen - though personally I would recommend just finding out how big the current window is, the only reason not to is if you are going to resize the window and that is very frowned upon.
