MetalComboBoxButton

public MetalComboBoxButton(JComboBox cb,
                           Icon i,
                           CellRendererPane pane,

                           boolean onlyIcon,

                           JList list)

方法详细信息

getComboBox

public final JComboBox getComboBox()

setComboBox

public final void setComboBox(JComboBox cb)

getComboIcon

public final Icon getComboIcon()

setComboIcon

public final void setComboIcon(Icon i)

isIconOnly

public final boolean isIconOnly()

setIconOnly

public final void setIconOnly(boolean isIconOnly)

isFocusTraversable

public boolean isFocusTraversable()

描述从类别复制： Component

返回此 Component是否可以成为焦点所有者。

重写：

isFocusTraversable在 Component

结果

true如果这个Component是可对焦的; false否则

另请参见：

Component.setFocusable(boolean)

setEnabled

public void setEnabled(boolean enabled)

描述从类别复制： AbstractButton

启用（或禁用）按钮。

重写：

setEnabled在 AbstractButton

参数

enabled - true启用按钮，否则为false

另请参见：

Component.isEnabled() ， Component.isLightweight()

paintComponent

public void paintComponent(Graphics g)

描述从类别复制： JComponent

调用UI代理的paint方法，如果UI代理不是null 。 我们通过委托一份Graphics对象的副本，以保护其余的油漆代码免受不可撤销的更改（例如Graphics.translate ）。

如果重写此在子类中，你不应该在通过永久性变化Graphics 。 例如，您不应该更改剪辑Rectangle或修改转换。 如果您需要执行这些操作，您可能会发现从Graphics中传递的操作更容易创建一个新的Graphics并进行操作。 此外，如果您不调用super的实现，则必须遵守不透明属性，即如果此组件不透明，则必须以非不透明颜色完全填写背景。 如果您不遵守不透明属性，您将可能会看到视觉工件。

在Graphics对象中传递的对象可能具有除了安装在其上的标识变换之外的变换。 在这种情况下，如果累积应用另一个变换，您可能会得到意想不到的结果。

重写：

paintComponent在 JComponent

参数

g - Graphics对象保护

另请参见：

JComponent.paint(java.awt.Graphics) ， ComponentUI

getMinimumSize

public Dimension getMinimumSize()

描述从类别复制： JComponent

如果最小尺寸设置为非null值，则返回。 如果UI代理的getMinimumSize方法返回一个非null值，那么返回那个; 否则推迟到组件的布局管理器。

重写：

getMinimumSize在 JComponent

结果

该值为 minimumSize属性
