我有一个JXTreeTable,并且实现了一个自定义的Renderer。
所以我有这段代码:
public class CustomTreeTableSpeseXCategoriaSpese extends JLabel implements TreeCellRenderer, TableCellRenderer {
/**
*
*/
private static final long serialVersionUID = 4842418316518803090L;
private Font fontTotale = new Font("Verdana", Font.BOLD, 12);
private Font fontNegativo = new Font("Verdana", Font.BOLD, 12);
@Override
public Component getTableCellRendererComponent(JTable table, Object value,
boolean isSelected, boolean hasFocus, int row, int column) {
setOpaque(true);
setHorizontalAlignment(SwingConstants.RIGHT);
if (row== table.getRowCount()-1) {
setForeground(Color.BLACK);
setBackground( Color.RED );
setFont(fontTotale);
}else if(row != table.getRowCount() && column !=3){
setForeground( Color.BLACK );
setBackground(new Color(200, 200, 200));
setFont(UtilitySwing.getTableFont());
}else if(row != table.getRowCount()-1 && column ==3){
//verifico il valore se negativo rosso
//se positivo blu
String valore = value.toString();
if(valore.startsWith("-")){
setForeground(Color.red);
setFont(fontNegativo);
}else{
setForeground(Color.blue);
setFont(fontNegativo);
}
}
setText(value != null ? value.toString() : "<null>");
return this;
}
public Component getTreeCellRendererComponent(JTree tree, Object value, boolean selected, boolean expanded, boolean leaf, int row, boolean hasFocus) {
setOpaque(true);
if (row== tree.getRowCount()-1) {
setForeground(Color.BLACK);
setOpaque(true);
setBackground( Color.RED );
setFont(fontTotale);
}else if(row != tree.getRowCount()){
setForeground( Color.BLACK );
setBackground(new Color(200, 200, 200));
setOpaque(true);
setFont(UtilitySwing.getTableFont());
}
setText(value != null ? value.toString() : "<null>");
return this;
}
}
这是创建JXTreeTable的代码:
public JTreeTable(){
JXTreeTable talbe = new JXTreeTable();
talbe .setTreeTableModel(new RandomTextTreeTableModel(listaConti));
talbe .setDefaultRenderer(Object.class, new CustomTreeTableSpeseXCategoriaSpese());
talbe .setTreeCellRenderer(new CustomTreeTableSpeseXCategoriaSpese());
}
如果我尝试运行此代码,则可以显示以下内容:
如果我尝试打开第一个节点,则可以看到以下内容:
我要这个:
1)显示全文
2)如何从图像中看到,我想在所有第一列中将背景色设置为灰色。我该如何解决?
编辑
该帖子不是重复的,因为在建议帖子中有JTree,但是在我的帖子中,我有JXTreeTable,这是不同的
最佳答案
这可以使用org.jdesktop.swingx.decorator.HighlightPredicate
来完成
HighlightPredicate hlPred = new HighlightPredicate() {
@Override
public boolean isHighlighted(Component renderer,
ComponentAdapter adapter) {
return someCondition ? true : false;
}
};
ColorHighlighter hl = new ColorHighlighter(hlPred, hlBgColor, hlFColor);
treeTable.addHighlighter(hl);
