[英]Java Swing - setting margins on TextArea with Line Border
As the title says, I am simply trying to set the margins (provide some padding) on a TextArea with a LineBorder set. 正如标题所说,我只是试图在TextArea上设置一个LineBorder设置的边距(提供一些填充)。 Without setting the Border, .setMargins works fine. 没有设置边框,.setMargins工作正常。 Here is the specific chunk of code. 这是特定的代码块。
aboutArea = new JTextArea("program info etc.....");
Border border = BorderFactory.createLineBorder(Color.BLACK);
aboutArea.setSize(400, 200);
aboutArea.setBorder(border);
aboutArea.setEditable(false);
aboutArea.setFont(new Font("Verdana", Font.BOLD, 12));
add(aboutArea);
I have tried each of these: 我尝试过以下各项:
aboutArea.setMargins(10,10,10,10);
.getBorders(aboutArea).set(10,10,10,10);
UIManager.put("aboutArea.margin", new Insets(10, 10, 10, 10));
but nothing affects the margins after I apply the border, the padding is always 0. Any ideas how to set the padding on the textArea with the border? 但是在应用边框后没有任何影响边距,填充总是为0.任何想法如何在带有边框的textArea上设置填充?
What if you try adding a CompoundBorder , won't this do, this will give you almost same thing 如果你尝试添加一个CompoundBorder会怎么样,这不会给你带来几乎相同的东西
JTextArea tarea = new JTextArea("program info etc.");
Border border = BorderFactory.createLineBorder(Color.BLACK);
tarea.setBorder(BorderFactory.createCompoundBorder(border,
BorderFactory.createEmptyBorder(10, 10, 10, 10)));
