In javascript, we need to obtain the coordinates of the mouse position in several ways. One is the relative position (browser window, document location). Almost all of these are using document. body. scrollTop, document. body. dom commands such as scrollLeft. I will introduce several instances in detail below. Example 1 The Code is as follows: Copy code Var xPos;Var yPos;Document. onmousemove = mouseMove;Function mouseMove (ev

handles, which can be forcibly converted to socket handles directly. Before encapsulating epoll, another step is to define a Data Structure to store data with an indefinite length so that it can be mounted to epoll events. struct mdata{ int fd; unsigned int len; char buf[2048]; mdata(){} mdata(char *s,const int length) { for(int i=0;i Epoll encapsulation can be started and edge-triggered. My idea is to record the epoll handle and parameters in the class, and maintain

The event types in android include button events and screen Touch events. Touch events are the basic events of screen Touch events, so it is necessary to have a deep understanding of them.A simple screen Touch action triggers a series of Touch events: ACTION_DOWN-> ACTION_MOVE...-> ACTION_MOVE-> ACTION_UPWhen the screen contains a ViewGroup and the ViewGroup contains a sub-view, how does the android system handle Touch events? Is ViewGroup used to process Touch events or child views used to proc

Swiperefreshlayout is the official Android Drop-down Refresh control, the use of simple, beautiful interface, unfamiliar friends can be random search to understand, here is no nonsense, directly into the business. First of all, give a flowchart, marked the role of several main methods, can be combined to see ha. This Drop-down refresh control principle is not difficult, the basic is to monitor the movement of the fingers, get the coordinates of the finger, through the calculation of what k

Ontouchevent method of a view returns False, the Ontouchevent method of its parent container is invoked, and if its parent container's Ontouchevent method returns false, it continues to be thrown up. When all elements do not handle this event, the event is eventually passed on to the activity processing, where the Ontouchevent method of the work is invoked. Well, now that the groundwork has been laid, then we will analyze the event distribution mechanism from the source point of view. Of cour

slider or click a certain position of the volume bar to adjust the volume. With the above foundation, this is easy to complete. First, let's take a look at the function of adjusting the volume by clicking a certain position in the volume bar: click a certain position in the volume bar and calculate the length value from the starting point of the volume bar to this position, divide the value by the total length of the volume bar (100 here) to get the percentage value, multiply the percentage val
