Java Swing如何在Nimbus中设置JButton大小？

标签： java swing jbutton nimbus

我正在尝试让我的按钮在我的GUI中具有相同的大小。但是，每当我使用setPreferredSize（）时，Nimbus似乎会自动设置某些按钮的高度。让Nimbus使所有按钮具有相同尺寸（即宽度和高度）的最佳方法是什么？在下面的示例代码中，第一行中的按钮的高度是正确的，但宽度不是。在第二行中，宽度是正确的，但高度不是。如何让所有按钮在Nimbus中显示相同的大小？

public class SampleNimbusProblem extends javax.swing.JDialog {

    /** Creates new form SampleNimbusProblem */
    public SampleNimbusProblem(java.awt.Frame parent, boolean modal) {
        super(parent, modal);
        initComponents();
    }

    /** This method is called from within the constructor to
     * initialize the form.

标准化大小的一种方法是将组件放入GridLayout。有关详细信息，请参阅Laying Out Components Within a Container。

  

..每当我setPreferredSize（），

顺便说一句 - 如果有的话，很少需要设置首选尺寸。让布局管理器（具有适当的填充和边框）可以在不同的屏幕分辨率，大小，PLAF和版本中计算正确的组件大小。

你是对的Nimbus非常错误（开发在第一季度的某个地方结束），在某些情况下忽略了PreferredSize的设置，这就是为什么有Resizing a Component

答案 2 :(得分：1)

这是我希望示例出现的方式。使用GroupLayout就可以了。它在Nimbus LAF中正确显示。再次感谢您的帮助。我想我需要重新考虑我对GridBagLayout的偏好。
