这是因为JTextArea
' 在调整大小时会自动设置其最小宽度。详细信息可在MigLayout 论坛上找到。粗略地总结一下,创建一个包含JTextArea
并让您进一步控制调整大小行为的面板。以下是上述论坛帖子的摘录:
static class MyPanel extends JPanel implements Scrollable
{
MyPanel(LayoutManager layout)
{
super(layout);
}
public Dimension getPreferredScrollableViewportSize()
{
return getPreferredSize();
}
public int getScrollableBlockIncrement(Rectangle visibleRect, int orientation, int direction)
{
return 0;
}
public boolean getScrollableTracksViewportHeight()
{
return false;
}
public boolean getScrollableTracksViewportWidth()
{
return true;
}
public int getScrollableUnitIncrement(Rectangle visibleRect, int orientation, int direction)
{
return 0;
}
}
然后,无论您在哪里使用 JTextArea,都使用包含文本区域的面板:
MigLayout thisLayout = new MigLayout("", "[][grow]", "[]20[]");
this.setLayout(thisLayout);
{
jLabel1 = new JLabel();
this.add(jLabel1, "cell 0 0");
jLabel1.setText("jLabel1");
}
{
JPanel textAreaPanel = new MyPanel(new MigLayout("wrap", "[grow,fill]", "[]"));
jTextArea1 = new JTextArea();
textAreaPanel.add(jTextArea1);
this.add(textAreaPanel, "cell 0 1 2 1,grow,wmin 10");
jTextArea1.setText("jTextArea1");
jTextArea1.setLineWrap(false);
}
