构造器详细资料

BEComboBoxUI

public BEComboBoxUI()

方法详细资料

createUI

public static javax.swing.plaf.ComponentUI createUI(javax.swing.JComponent c)

Creates the ui.

参数:

c - the c

返回:

the component ui

isUseParentPaint

public boolean isUseParentPaint()

是否使用父类的绘制实现方法，true表示是.

因为在BE LNF中，边框和背景等都是使用N9图，没法通过设置背景色和前景 色来控制JComboBox的颜色和边框，本方法的目的就是当用户设置了进度条的border或背景色 时告之本实现类不使用BE LNF中默认的N9图填充绘制而改用父类中的方法（父类中的方法 就可以支持颜色的设置罗，只是丑点，但总归是能适应用户的需求场景要求，其实用户完全可以 通过JComboBox.setUI(..)方式来自定义UI哦）.

指定者:

isUseParentPaint 在接口中 BeautyEyeLNFHelper.__UseParentPaintSurported

返回:

true, if is use parent paint
