Case research and actual combat experience in the Iron Flex layout framework in the Java class library
Introduction:
When writing Java applications, using the appropriate layout framework can improve development efficiency and user experience.The Iron Flex layout framework is an open source Java class library that provides a simple and flexible way to achieve the layout of the user interface.This article will explore the case research and actual combat experience of the Iron Flex layout framework, including how to use Iron Flex to build a complex layout and deal with adaptation issues on different devices.
Iron Flex Introduction:
Iron Flex is a Java -based layout framework that helps developers to easily create a user interface layout.It is based on the Flexbox layout model and has the characteristics of simple and easy -to -use and flexibility, and can adapt to different screen size and equipment.Using Iron Flex, developers can write a complex layout by writing simple code and adapting to different devices.
case study:
The use of the Iron Flex layout framework is displayed by a case.Suppose we want to build a simple login page, including a user name input box, a password input box, and a login button.With the Iron Flex layout framework, we can easily place them on the page.
First, we need to import the library file of the Iron Flex layout framework in the project.You can add it to the dependence of the project through the construction tools such as Maven.
Next, we create a Java class to achieve the layout of the login page and use the API provided by Iron Flex to define the layout attributes of the element.The following is an example code:
import com.github.dakusui.flexmark.java.lang.FlexLang;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.PasswordField;
import javafx.scene.control.TextField;
import javafx.scene.layout.*;
import javafx.stage.Stage;
public class LoginApplication extends Application {
@Override
public void start(Stage primaryStage) {
// Create a user name input box
TextField usernameField = new TextField();
usernamefield.setprompttext ("user name");
// Create a password input box
PasswordField passwordField = new PasswordField();
passwordField.setprompttext ("password");
// Create the login button
Button loginButton = new Button("登录");
// Use the Flex layout framework to set the layout attributes of the element
FlexLang.get().setFlexProperties(usernameField, "flex: 1 1 auto");
FlexLang.get().setFlexProperties(passwordField, "flex: 1 1 auto");
FlexLang.get().setFlexProperties(loginButton, "flex: 1 1 auto");
// Create a layout container and add the element to the container
HBox container = new HBox(usernameField, passwordField, loginButton);
// Create the scene and set the container as the root node
Scene scene = new Scene(container);
// Set the scene and display the window
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
In the above sample code, we created a HBOX as the layout container and added the user name input box, password input box and login button to the container.With the API provided by Iron Flex, we can easily set a flexible layout attribute for each element.In this example, we set the `Flex` property of all elements to` 1 1 Auto`, which means that they will allocate the remaining space average according to the available space.
Experience:
In practice, when using the Iron Flex layout framework, we can follow the following empirical rules to achieve better results:
1. Familiar with the Flexbox layout model: Understanding the basic concepts and attributes of the Flexbox layout model, including the attributes of containers and projects, are very important for using Iron Flex.
2. Use flexible layout attributes: Iron Flex provides a rich layout attribute, which can define the layout attributes of the element according to needs.The `Flex` attribute of the element can be reasonably set to achieve adaptation of different devices.
3. Use container and nested layout: Use a container to organize elements, and to embed the container to achieve a more complex layout.Reasonable use of container and nested layout can improve the flexibility and scalability of the layout.
4. Test and debug layout: When achieving complex layout, we need to test and debug to ensure the display effect of the layout in different devices and screen size.Iron Flex provides convenient debugging tools and APIs to help us test and debug in layout.
Summarize:
The Iron Flex layout framework is a powerful and flexible Java class library that can help developers easily create a user interface layout.Through case research and actual combat experience, we understand Iron Flex's basic usage, flexible layout attributes and practical experience.Using Iron Flex, we can build a complex layout and deal with adaptation issues on different devices.If you are interested in the Iron Flex layout framework, it is recommended that you learn more about your documentation and example code in detail and practice and try in actual projects.
