我正在使用TableCellEditor：

setRow(table.getEditingRow());
if (m.isPressed() && table.isRowSelected(table.getEditingRow()) && e.isControlDown()) {
setBackground(DaimlerColor.LIGHT_BLUE);
}
}
};
playButton.addMouseListener(ml);
playButton.addActionListener(new ActionListener() {

addMouseListener(new MouseAdapter() {

System.out.println("CLCIKED");
return this;
}
@Override

和一个TableCellrenderer：
package gui.table;
import event.TestController;

import java.util.LinkedList;
import java.util.List;
import javax.swing.BorderFactory;

import org.jdom2.Document;
import org.jdom2.Element;
@SuppressWarnings("serial")
public class TestcaseCellRenderer extends TestcasePanel implements TableCellRenderer {
public List<String> data;
MainWindow gui = null;
public TestController tgc = null;
public TestcaseCellRenderer() {
super();
setName("Table.cellRenderer");
}
public TestcaseCellRenderer(List<String> names, MainWindow gui2, TestController tgc) {
super();
this.data = names;
this.gui = gui2;
this.tgc = tgc;
setName("Table.cellRenderer");
}
@Override
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus,
int row, int column) {
this.setToolTipText("Click play to rerun this Testcase");
System.out.println("Rendering your ass!");
this.setName(data.get(row));
setPlaybuttonIcon(gui.getTestcasetableModelIcon(row));
setClickable(tgc.clickable);
if (row <= gui.currentTestcase) {
Document doc = tgc.getDoc();
List<Element> cases = doc.getRootElement().getChildren();
List<Element> teststeps = cases.get(row).getChildren();
List<String> attributes = new LinkedList<String>();
for (Element teststep : teststeps) {
try {
if (teststep.getChildren("result").get(gui.sutPaths.getSelectedIndex()).getAttributeValue("status") != null) {
attributes.add(teststep.getChildren("result").get(gui.sutPaths.getSelectedIndex())
.getAttributeValue("status"));
}
else {
attributes.add("empty");
}
} catch (Exception e) {
attributes.add("empty");
}
}
if (attributes.contains("empty")) {
setButton("");
} else if (attributes.contains("failed")) {
setButton("failed");
} else {
setButton("passed");
}
} else {
setButton("");
}
if (tgc.isRerunning() && tgc.getEventRow() == row) {
setButton("");
}
this.setBorder(BorderFactory.createEmptyBorder());
this.setBackground(isSelected ? DaimlerColor.LIGHT_BLUE : (row % 2 == 1 ? DaimlerColor.DARK_WHITE
: DaimlerColor.WHITE));
return this;
}
}
以某种方式，如果我单击表中的文本，它只会设置第二次单击的焦点？它也仅每第二次触发一次fireEdizingCanceled事件吗？这是为什么？
感谢您的任何想法。
最佳答案
不知何故，如果我单击表格中的文本，只会设置焦点
每秒点击一次？这是为什么？
正确，这是从XxxTableCellEditor调用的MouseEvents的默认值
您可以更改myEditor.setClickCountToStart(1);
从API中实现的所有XxxCellRenderer，Mouse和内部方法中调用Key，您测试Renderer（也是Editor）内部的怪异事物，诸如此类的艰苦工作之类的大笑会导致重新绘制冻结，并且仅在mouse_over_hover上完成单元刷新
编辑
我需要在哪里打电话？我的TableCellEditor没有这个
方法。
伪码
JTable table = new JTable(model);
DefaultCellEditor editor = new DefaultCellEditor(......); // abstract or custom name
editor.setClickCountToStart(2); // for Compound JComponents (JComboBox) is more userfriendly invoke Editor on second click
table.getColumnModel().getColumn(1).setCellEditor(editor);
