JTextField:当文本太长时，如何在JTextField的左侧设置文本 [英] JTextField : How to set text on the left of JTextField when text too long

问题描述

我要在JTextField中显示很长的String.如果String太长，即使我使用setHorizontalAlignment(JTextField.LEFT)

I have a long String that I want to display in a JTextField. If the String is too long, it is showing the right-portion of the String, rather than the left portion, even when I use setHorizontalAlignment(JTextField.LEFT)

例如，如果我的String是"JTextField示例，此文本太长" ，则应显示为...

For example, if my String is "JTextField example , this text is too long", it should show as...

|----------------------|
| JTextField example ..|
|----------------------|

但是它显示为...

|----------------------|
| this text is too long|
|----------------------|

有人可以建议如何解决此问题.

Could someone please suggest how this can be fixed.

推荐答案

当字段的大小大于字符串的字符数时，horizo​​ntalAlignment可以正常工作，但是如果字段的大小小于字符串的字符数，则只对LEFT_ALIGNMENT进行处理.其创建的setText，而不与以后的setText一起使用.

the horizontalAlignement works fine when the size of the field is bigger than the number of chars of the string, but if it is smaller it only does the LEFT_ALIGNMENT with the setText of its creation, not with any later setText.

您可以使用以下命令将插入符号的位置强制为文本的开头:

You could force the position of the caret to the begining of the text using:

myTextField.setCaretPosition(0);
