    这是一个创建于 566 天前的主题,其中的信息可能已经有所发展或是发生改变。

    我用 jformdesigner 设计了一个界面,并且开启了显示行数,当前 ui 也有行数显示,如下 bhW7b 但是在我运行起来之后就没有行数显示了 H9o4Q 刚开始以为是 Flat 皮肤和 Mig 布局问题 但是我使用官方 demo 进行测试时候发现是可以显示行数的。 ykucy

    所以我不知道怎么解决这个问题了。找遍全网也没有类似的问题,

    测试代码:

    
    import java.awt.*;
    import java.awt.event.*;
    import javax.swing.*;
    import net.miginfocom.swing.*;
    import org.fife.ui.rsyntaxtextarea.*;
