tab space on a JLabel not showing - weird - Java

问题

I'm trying to update a JLabel with new text and I need this text to have tabed space.

This is my code:

public void setNewLabelTxt(String text)
{
    nameLabel.setText(text + "\t");
}

The label is updated but there is no tab space at the end and I can't figure why. As far as I know \t is the way to add tab space.

回答1:

JLabel doesn't render \t in any special way (ie, it doesn't convert the \t to spaces before rendering it).

Instead, you should use something like

text = text.replaceAll("\t", "    ");

Before applying it to the label.
