JLabel.setText()中的换行符 [英] newline character in JLabel.setText()
问题描述
使用JLabel.setText()时如何插入换行符?我尝试使用HTML，但似乎可以使它适用于setText，仅适用于jLabel的初始声明
How can I insert a newline when I am using JLabel.setText()? I tried to use Html but can seem to make it work for setText, only for the initial declaration of the jLabel
最初声明jlabel时的方法是:
the way to do it when initially declaring the jlabel is:
label = new JLabel("<html>Hello World!<br>blahblahblah</html>");
我的代码:
textString += "<html> quantityTextField.getText() +
theInventory.findItem(UPCTextField.getText()).toString() + <br> </html>";
purchaseInfo.setText( textString);
它显示html标记和方法名称，而不是方法返回的字符串
it displays the html tags and the method names instead of the string returned by the methods
推荐答案
如果您的setText()调用更改了JLabel的首选尺寸，则需要在容器上调用revalidate()来重做布局.
If your setText() call changes the preferred dimensions of the JLabel, then you need to call revalidate() on the container to get the layout redone.
看一下您添加的代码片段，我在行的最后看到一个
－不管怎样它实际上不会做任何事情－以及很多被错误引用的方法调用，这些调用使得方法名称是HTML的一部分.如果您按照
Looking at the code snippet you've added, I see a
at the very end of the line -- which won't really do anything anyway -- and a lot of misquoted method calls which are done such that the method names are part of the HTML. If you do something along the lines of
label.setText("<html>Hello World!<br>blahblahblah</html>");
label.getParent().revalidate();
您的换行符应该显示出来.
your newline ought to show up.
