java - Intellij 从 gui 表单构建项目时给我一个错误

Question

我对 Java 有点陌生，并且使用 intellij 来学习 gui。如果我理解正确的话，当你设计它时，intellij不会为你的gui构建源代码，你必须选择build->buildproject。它会自动生成代码，但会提供一些导致我的代码出错的信息。在任何显示“com.intellij.uiDesigner.core.GridConstraints”的地方，它在编辑器中都是红色的。

import javax.swing.*;
import java.awt.*;

public class GameGUI {
    private JPanel contolPanel;
    private JLabel labelImage;

    {
// GUI initializer generated by IntelliJ IDEA GUI Designer
// >>> IMPORTANT!! <<<
// DO NOT EDIT OR ADD ANY CODE HERE!
        $$$setupUI$$$();
    }

    /**
     * Method generated by IntelliJ IDEA GUI Designer
     * >>> IMPORTANT!! <<<
     * DO NOT edit this method OR call it in your code!
     *
     * @noinspection ALL
     */
    private void $$$setupUI$$$() {
        contolPanel = new JPanel();
        contolPanel.setLayout(new com.intellij.uiDesigner.core.GridLayoutManager(1, 2, new Insets(0, 0, 0, 0), -1, -1));
        contolPanel.setAlignmentX(1.0f);
        contolPanel.setAlignmentY(1.0f);
        contolPanel.setAutoscrolls(false);
        contolPanel.putClientProperty("html.disable", Boolean.FALSE);
        labelImage = new JLabel();
        labelImage.setIcon(new ImageIcon(getClass().getResource("/images/java.png")));
        labelImage.setText("Label");
        contolPanel.add(labelImage, new com.intellij.uiDesigner.core.GridConstraints(0, 0, 1, 1, com.intellij.uiDesigner.core.GridConstraints.ANCHOR_WEST, com.intellij.uiDesigner.core.GridConstraints.FILL_NONE, com.intellij.uiDesigner.core.GridConstraints.SIZEPOLICY_FIXED, com.intellij.uiDesigner.core.GridConstraints.SIZEPOLICY_FIXED, null, null, null, 0, false));
        final com.intellij.uiDesigner.core.Spacer spacer1 = new com.intellij.uiDesigner.core.Spacer();
        contolPanel.add(spacer1, new com.intellij.uiDesigner.core.GridConstraints(0, 1, 1, 1, com.intellij.uiDesigner.core.GridConstraints.ANCHOR_CENTER, com.intellij.uiDesigner.core.GridConstraints.FILL_HORIZONTAL, com.intellij.uiDesigner.core.GridConstraints.SIZEPOLICY_WANT_GROW, 1, null, null, null, 0, false));
    }

    /**
     * @noinspection ALL
     */
    public JComponent $$$getRootComponent$$$() {
        return contolPanel;
    }
}

只需将 IDEA_HOME\redist\forms_rt.jar 文件添加到 module dependencies .

您可以关闭源代码生成并使用 GUI 设计器的默认选项，该选项将检测字节码，以便您在编辑器中根本看不到生成的代码。
