制作表格与JPanels列表（应用百分比大小列） [英] Making Table With List Of JPanels ( With Applying Percentage Size Columns )
本文介绍了制作表格与JPanels列表（应用百分比大小列）的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
在这篇文章制作包含JPanel列表的表我可以制作一个表格与面板列表。这个表有很多功能，但我需要一个新的功能，它是应用百分比列。这意味着我喜欢所有列的宽度不等于和一个浮点数组确定。
这是我的班级table：
In this post Making Table With List Of JPanels I can make a Table with lists of panel. And this table has many features but I need to a new feature and it is applying percentage columns.It means I like to width of all columns not equals and with a array of floats determines.
This is my class table :
import javax.swing.*;
import java.awt.*;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import java.util.Vector;
public class PanelTable extends JPanel {
private String data[][];
private String columns[];
private int numberOfRows;
private int numberOfColumns;
private JTextArea[] header;
private JTextArea[][] cell;
public PanelTable(String data[][], String columns[]) {
setLayout(new BoxLayout(this, BoxLayout.Y_AXIS));
this.data = data;
this.columns = columns;
numberOfRows = data.length;
numberOfColumns = columns.length;
makeHeader();
makeCells();
}
public void makeCells() {
cell = new JTextArea[numberOfRows][numberOfColumns];
for (int rowIndex = 0; rowIndex < numberOfRows; rowIndex++) {
add(getRow(numberOfColumns, rowIndex));
}
}
public void makeHeader() {
header = new JTextArea[numberOfColumns];
for (int columnIndex = 0; columnIndex < numberOfColumns; columnIndex++) {
JTextArea ta = new JTextArea();
ta.setComponentOrientation(ComponentOrientation.RIGHT_TO_LEFT);
ta.setBackground(new Color(57, 77, 112));
ta.setForeground(Color.WHITE);
ta.setText(columns[columnIndex]);
ta.setFont(new Font("Calibri Light", Font.BOLD, 25));
ta.setLineWrap(true);
ta.setWrapStyleWord(true);
ta.setEditable(false);
header[columnIndex] = ta;
}
JPanel rowHeader = new JPanel();
rowHeader.setLayout(new BoxLayout(rowHeader, BoxLayout.X_AXIS));
for (int i = 0; i < numberOfColumns; i++) {
rowHeader.add(header[i]);
}
add(rowHeader);
}
public Component getRow(int numberOfColumns, int rowIndex) {
JPanel row = new JPanel();
//use GridLayout if you want equally spaced columns
row.setLayout(new BoxLayout(row, BoxLayout.X_AXIS));
for (int columnIndex = 0; columnIndex < numberOfColumns; columnIndex++) {
row.add(getCell(rowIndex, columnIndex));
}
return row;
}
public Component getCell(int rowIndex, int columnIndex) {
if (cell[rowIndex][columnIndex] == null) {
JTextArea ta = new JTextArea();
ta.setLineWrap(true);
ta.setWrapStyleWord(true);
ta.setEditable(false);
ta.setSize(50, ta.getHeight());
ta.setComponentOrientation(ComponentOrientation.RIGHT_TO_LEFT);
ta.setBorder(BorderFactory.createLineBorder(Color.BLACK));
ta.setText(data[rowIndex][columnIndex]);
ta.setFont(new Font("Bmitra", Font.BOLD, 15));
cell[rowIndex][columnIndex] = ta;
}
return cell[rowIndex][columnIndex];
}
}
这是一个gui示例测试：

推荐答案
执行此操作：
首先创建一个宽度大小的数组。例如：
Do this: First create an array of width size. for example :
final int[] columnsWidth = { 300, 100, 50, 300, 50 };
然后在你的方法makeHeader和getCell，你在那里设置文本区域的所有属性，设置首选大小也。请参阅下面的代码。这应该给你基于size数组的宽度。
then on your method makeHeader and getCell, where you are setting all the attributes of text area, set preferred size also. See the code below. This should give you the width based on the size array.
ta.setPreferredSize(new Dimension(columnsWidth[columnIndex], ta.getHeight()));
让我知道它是否适合你：）
Let me know if it works for you :)
以下是完整的代码：
