在选择时突出显示细线十字图案中的相关单元格
Highlight related cells in hairline cross pattern on selection
我想为 JXTable
添加细线交叉高亮。但是我可以突出显示当前行或当前列;从来没有。
我目前有的是红色部分,黄色部分是我要添加的。

但不幸的是,我现在遇到了工件问题。类似于下图(取自仅红色版本)

它似乎在使用 JTable 时有效(尽管如果您希望该列具有优先级,则需要更改 if 语句的顺序)。因此,似乎 JXTable 做了一些导致问题的额外渲染。
所以这是一种基于 Table Row Rendering 的替代方法,它似乎适用于 JXTable:
JXTable table = new JXTable(new CustomTableModel())
{
public Component prepareRenderer(
TableCellRenderer renderer, int row, int column)
{
Component c = super.prepareRenderer(renderer, row, column);
if (column == getSelectedColumn()) { c.setBackground(Color.RED); }
else if (row == getSelectedRow()) { c.setBackground(Color.YELLOW); }
else c.setBackground(getBackground());
return c;
}
};
以上代码替换自定义渲染器:
//table.setDefaultRenderer(Object.class, new CustomTableCellRenderer());
注意:在您的 "MCVE" 我的建议中,您删除了:
boolean highlightRow = false;
table.setRowSelectionAllowed(highlightRow);
table.setColumnSelectionAllowed(!highlightRow);
为什么?我只给了你以上2个改动。
这就是为什么您需要 post 一个合适的 "MCVE" 以便我们可以确保您正确实施了建议。
