Hangzhou began heavy rain again. When I went out to the canteen for a meal, my shoes went into the water. When the weather is hot, simply wear sandals.

I have been debugging prefuse and double-click the response to call the browser's permission to access the new page. Because the applet is used, it is troublesome to package it into a jar package and grant permissions to the digital signature. I always wanted to go around, but unfortunately I didn't find any good solutions. So far.

Prefuse is a set of API toolkit, which has two projects. One is a Java-based API call (prefuse Toolkit) that generates an applet or window.ProgramAnd prefuse flare, which can generate flash. I use prefuse toolkit, which is not used for actioinscript. I read a few books and it is hard to get started without having done anything. Prefuse uses Visual graphs to display structured or unstructured data. It has a variety of animation effects and can interact with users to respond to various events, drag and drop the mouse, click, double-click, and scroll up. The data source can be an XML file, a CSV file, or a database. Data of some tree structures or network topologies, such as the file system structure and organization diagram. I feel it will be very good to use this. It can also be used to display datasets of the timeline class.

Nowadays, there are a lot of social network applications, and many places have friends. The friend relationship between users is a network, and the relationship between friends and friends spread. It feels good to use a picture to display the image.

There are several examples on the prefuse website. You can download the source program and view it. Unfortunately, it is still in beta version, even though there are few English documents. To gain a deeper understanding, you need to read the API documentation and learn more about it. The data provided in this example is read from XML, while most applications operate on databases. Although it provides API packages read from the database, it is also a headache.

I am doing something similar to a tree structure. The data source uses the MySQL database and is published as an applet. Added some other action responses.
