Interpret the technical principle of the Iron Icons framework in the Java class library
Iron iCons is an icon framework for the Java library, which provides rich icon resources and technical principles.This article will focus on the technical principles of the Iron iCons framework, and explain the complete programming code and related configuration when required.
1. Technical principles of Iron icons framework
Iron iCons framework is based on the Java class library and can help developers use icons in applications.The main principle is to use the concept of font icon to design the icon as font file.Developers can realize the function of icon in the application by referenced the required icons in the HTML or Java code.
1. The concept of font icon
The font icon refers to the icon that can be designed as an icon that can be used like fonts in a webpage or application.They can set the size, color and other styles through CSS, and can be easily scaled and modified.
2. IconFont
Iconfont is a common font icon technology that designs icons into similar font formats and gives each icon a unicode code.By specifying the unicode code, you can use the corresponding icon in HTML or Java code.
3. Iron icons implementation
Iron iCons designed each icon as an independent font file and included it in a Java class library.When using Iron ICons, developers need to import this type of library and quote the required icons on the Java code or HTML page.
2. Programming code and related configuration
The following is an example of related programming code and configuration using Iron icons:
1. Configuration
In the construction configuration file of the project, Iron iCons needs to be added.For example, in the Maven project, the following code can be added to the POM.XML file:
<dependency>
<groupId>com.github.vxe</groupId>
<artifactId>iron-icons</artifactId>
<version>2.1.3</version>
</dependency>
2. Java code
In the Java code, you can use the `icon` class to quote the icon in Iron icons.The following is an example code:
import com.github.vxe.icon.Icon;
import com.github.vxe.icon.IronIcons;
public class Main {
public static void main(String[] args) {
// Use code to reference a icon
Icon bookmarkIcon = IronIcons.BOOKMARK;
// Print the unicode code position of the icon
System.out.println("Unicode 码位: " + bookmarkIcon.getCodepoint());
}
}
3. HTML page
In the HTML page, you can use the `Iron-ICON>` tag to reference the icon in Iron icons.The following is an example code:
html
<!DOCTYPE html>
<html>
<head>
<script src="https://cdn.jsdelivr.net/npm/@webcomponents/custom-elements@1.3.0/custom-elements.min.js"></script>
<link rel="import" href="iron-icons/iron-icons.html">
</head>
<body>
<!-Quote a icon in the page->
<iron-icon icon="iron-icons:bookmark"></iron-icon>
</body>
</html>
Through the above example code and configuration, you can successfully use the Iron Icons framework to display icons in the Java library.
Summarize:
Iron icons is an icon framework, which is based on the concept of Java class library and font icon.Developers can use rich icon resources in applications through the technical principles provided by Iron Icons.Programming code and related configuration examples show how to use the Iron iCons framework in the Java code and HTML pages.It is hoped that this article can help readers understand the technical principles and usage of the Iron Icons framework.
