用水平线分隔JTable中的实例
用水平线分隔JTable中的实例
提问于 2014-07-18 21:00:55
我正在编辑一个开源的“我的世界”启动器，我有一个小问题……我有一个用于各种实例的JTable，我想用水平线分隔每个实例。下面是JTable类：
public class InstanceTable extends JTable {
public InstanceTable() {
setShowGrid(false);
setRowHeight(Math.max(getRowHeight() + 4, 20));
setIntercellSpacing(new Dimension(0, 0));
setFillsViewportHeight(true);
setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
}
@Override
public void setModel(TableModel dataModel) {
super.setModel(dataModel);
try {
getColumnModel().getColumn(0).setMaxWidth(24);
} catch (ArrayIndexOutOfBoundsException e) {
}
}
}下面是TableModel类：
public class InstanceTableModel extends AbstractTableModel {
private final InstanceList instances;
private final ImageIcon instanceIcon;
private final ImageIcon customInstanceIcon;
private final ImageIcon downloadIcon;
public InstanceTableModel(InstanceList instances) {
this.instances = instances;
instanceIcon = new ImageIcon(SwingHelper.readIconImage(Launcher.class, "instance_icon.png")
.getScaledInstance(16, 16, Image.SCALE_SMOOTH));
customInstanceIcon = new ImageIcon(SwingHelper.readIconImage(Launcher.class, "custom_instance_icon.png")
.getScaledInstance(16, 16, Image.SCALE_SMOOTH));
downloadIcon = new ImageIcon(SwingHelper.readIconImage(Launcher.class, "download_icon.png")
.getScaledInstance(14, 14, Image.SCALE_SMOOTH));
}
public void update() {
instances.sort();
fireTableDataChanged();
}
@Override
public String getColumnName(int columnIndex) {
switch (columnIndex) {
case 0:
return "";
case 1:
return _("launcher.modpackColumn");
default:
return null;
}
}
@Override
public Class<?> getColumnClass(int columnIndex) {
switch (columnIndex) {
case 0:
return ImageIcon.class;
case 1:
return String.class;
default:
return null;
}
}
@Override
public void setValueAt(Object value, int rowIndex, int columnIndex) {
switch (columnIndex) {
case 0:
instances.get(rowIndex).setSelected((boolean) (Boolean) value);
break;
case 1:
default:
break;
}
}
@Override
public boolean isCellEditable(int rowIndex, int columnIndex) {
switch (columnIndex) {
case 0:
return true;
case 1:
return false;
default:
return false;
}
}
@Override
public int getRowCount() {
return instances.size();
}
@Override
public int getColumnCount() {
return 2;
}
@Override
public Object getValueAt(int rowIndex, int columnIndex) {
Instance instance;
switch (columnIndex) {
case 0:
instance = instances.get(rowIndex);
if (!instance.isLocal()) {
return downloadIcon;
} else if (instance.getManifestURL() != null) {
return instanceIcon;
} else {
return customInstanceIcon;
}
case 1:
instance = instances.get(rowIndex);
return "<html>" + SwingHelper.htmlEscape(instance.getTitle()) + getAddendum(instance) + "</html>";
default:
return null;
}
}
private String getAddendum(Instance instance) {
if (!instance.isLocal()) {
return " <span style=\"color: #cccccc\">" + _("launcher.notInstalledHint") + "</span>";
} else if (!instance.isInstalled()) {
return " <span style=\"color: red\">" + _("launcher.requiresUpdateHint") + "</span>";
} else if (instance.isUpdatePending()) {
return " <span style=\"color: #3758DB\">" + _("launcher.updatePendingHint") + "</span>";
} else {
return "";
}
}
