GroupLayout 在 java swing 中给出错误

我收到一长串错误。谁能向我建议 GroupLayout

layout.setHorizontalGroup(
    layout.createSequentialGroup()
        .addComponent(new JLabel("Enter Book Name"))
        .addComponent(new JTextField("TextField", 20))
);

错误:

    Exception in thread "main" java.lang.IllegalStateException:
        javax.swing.JTextField[,0,0,0x0,invalid,layout=javax.swing.
            plaf.basic.BasicTextUI$UpdateHandler,alignmentX=0.0,
            alignmentY=0.0,border=javax.swing.plaf.BorderUIResource$
            CompoundBorderUIResource@3d0bbf9e,flags=296,maximumSize=,
            minimumSize=,preferredSize=,caretColor=sun.swing.

            ,margin=javax.swing.plaf.InsetsUIResource[top=0,left=0,
            bottom=0,right=0],selectedTextColor=sun.swing.
            PrintColorUIResource[r=51,g=51,b=51],selectionColor=javax.
            swing.plaf.ColorUIResource[r=184,g=207,b=229],columns=20,
            columnWidth=0,command=,horizontalAlignment=LEADING]
            is not attached to a vertical group
            at javax.swing.GroupLayout.checkComponents(Unknown Source)
            at javax.swing.GroupLayout.prepare(Unknown Source)

I am getting a long list of errors. Can anyone suggest to me where I am going wrong with GroupLayout.

layout.setHorizontalGroup(
    layout.createSequentialGroup()
        .addComponent(new JLabel("Enter Book Name"))
        .addComponent(new JTextField("TextField", 20))
);

Error:

使用 GroupLayout 时,必须指定水平和垂直布局。每个组件必须在每个组中精确指定一次。不这样做会导致此错误。

此外,请确保正确交叉孵化每个项目。如果您要制作网格,请确保两个方向都是平行线序列,反之亦然。如果您要制作一排按钮或其他东西,请确保它们以一种方式平行,另一种方式顺序。

When you use GroupLayout, you have to specify a Horizontal and a Vertical layout. Each component must be specified exactly once in each group. Not doing this causes this error.

Additionally, make sure you cross hatch each item properly. If you're making.a grid, be sure that both directions are sequences of parallels or vice versa. If you are making one row of buttons or something, make sure they are parallel one way and sequential another.
