Java Swing JtextField插入 [英] Java Swing JtextField inset

问题描述

我正在使用Netbeans GUI，我想在我的jTextField的开头添加3个像素的空间:

I am working with Netbeans GUI and I would like to add 3 pixels of space at the beginning of my jTextField :

我已经尝试过在GUI中使用setMargin，setInset，但是它没有任何改变.

I have tryied with setMargin, setInset in the GUI but it doesn't change anything.

我还有一个问题，为什么右下边框没有四舍五入?这是我的代码:

I have another question, why the bottom right border is not rounded ? here is my code :

Border roundedBorder = new LineBorder(new Color(210,210,210), 1, true);
researchTextField.setBorder(roundedBorder);

非常感谢您

致谢

推荐答案

使用setMargin(...)应该可以.

但是，如果您还使用边框，则可能是问题所在.

However, if you are also using a Border then that may be the problem.

尝试使用CompoundBorder，其中内部边框是EmptyBorder()，而外部边框是您的另一个边框.例如:

Try using a CompoundBorder where the inner border is an EmptyBorder() and the outer border is your other border. For example:

Border rounded = new LineBorder(new Color(210,210,210), 1, true);
Border empty = new EmptyBorder(0, 3, 0, 0);
textField.setBorder(rounded);
Border border = new CompoundBorder(rounded, empty);

为什么右下边框没有四舍五入?

why the bottom right border is not rounded ?

我不确定为什么您的右下角没有四舍五入.在XP上使用Metal LAF，右边界(顶部和底部)显示为圆形，但左边界未显示为圆形.当我使用2或更大的边框大小时，所有角均显示为相等的圆角.

I'm not sure why your bottom/right is not rounded. Using the Metal LAF on XP the right borders (top and bottom) appear rounded but the left borders are not rounded. When I use a border size of 2 or more all corners appear equally rounded.
