[英]Java swing BasicTextFieldUI painting ISSUE
我正在一个项目中,我需要更改JTextFields
的样式 。 我扩展了BasicTextFieldUI
,并覆盖了paintSafely
方法,但是,当它绘制组件时,它会绘制一个边框 (即使border设置为null
)。 我尝试查看BasicTextUI
类的内部,以查看可以绘制该边框的内容,但没有找到任何东西。
为什么此代码将在组件周围创建边框?
这是我的代码:
public class CustomTextField extends BasicTextFieldUI{
int borderThickness, edgeRoundness;
@Override
protected void paintSafely(Graphics g) {
JComponent c = (JComponent)this.getComponent();
Graphics2D g2 = (Graphics2D)g;
g2.setColor(c.getBackground());
borderThickness = 2;
edgeRoundness = 20;
g2.setColor(c.getForeground());
g2.fillRoundRect(0, 0, c.getWidth(), c.getHeight(), edgeRoundness+5, edgeRoundness+5);
g2.drawRoundRect(0, 0, c.getWidth(), c.getHeight(), edgeRoundness+5, edgeRoundness+5);
g2.setColor(c.getBackground());
g2.fillRoundRect(borderThickness, borderThickness, c.getWidth()-(int)(borderThickness*2.5), c.getHeight()-(int)(borderThickness*2.5), edgeRoundness, edgeRoundness);
g2.drawRoundRect(borderThickness, borderThickness, c.getWidth()-(int)(borderThickness*2.5), c.getHeight()-(int)(borderThickness*2.5), edgeRoundness, edgeRoundness);
super.paintSafely(g);
}
}
可能是什么错误? 是否有其他方法可用来喷涂组件?
我在这篇文章中找到了答案! 看来,通过将border设置为null
,我对PLAF说过要使用它自己的border。 摆动JTextField怎么去除边框?
