问题描述
我创建了一个带有 JScrollPane
的 JTable
。当表格的高度大于滚动窗格的高度时,会出现一个滚动条。如果最小化 JFrame
虽然我没有改变它的大小,但滚动条消失并且滚动窗格向下延伸。
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
public class Main {
static String columns[] = {"Date","Price","URL","Expired"};
static String data[][] = new String[8][4];
/*
* The data that should be provided to the JTable is
* replaced with some example data because the method
* of getting this data is complicated and doesn't
* change anything at the outcome.
*/
public static void main(String[] args) {
loadGui();
}
public static void loadGui() {
for (int i = 0; i < 8; i++) {
for (int j = 0; j < 4; j++) {
data[i][j] = "Example data " + i + " " + j;
}
}
JFrame mainFrame = new JFrame();
mainFrame.setSize(800,300);
mainFrame.setResizable(false);
mainFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
mainFrame.setVisible(true);
JTable table = new JTable(data,columns);;
table.setPreferredScrollableViewportSize(table.getPreferredSize());
JScrollPane pane = new JScrollPane(table);
pane.setViewportView(table);
pane.setSize(785,100);
mainFrame.add(pane);
table.getTableHeader().setReorderingAllowed(false);
table.setDefaultEditor(Object.class,null);
table.setFocusable(false);
table.setRowSelectionAllowed(false);
}
}
我正在寻找一种方法来阻止滚动窗格向下延伸并保持其大小。
