我在JTable单元格中遇到了tooltip的问题。在我的自定义单元格渲染器中,调用了setToolTipText
。但是当盘旋到表格单元格时,工具提示没有显示在正确的位置,尽管文本是正确的。关于如何为单元格渲染器类的表格单元设置tootip位置的任何想法。
P.S我无法在此发布实际代码。 感谢

答案 0 :(得分:0)
如果没有提供任何代码示例,我可以这样说:
使用set toolTipText,如下所示:
JTable table = new JTable() {
public Component prepareRenderer(TableCellRenderer renderer, int row, int column) {
Component c = super.prepareRenderer(renderer, row, column);
if (c instanceof JComponent) {
JComponent jc = (JComponent) c;
jc.setToolTipText(getValueAt(row, column).toString());
}
return c;
}
};
或者您可以使用此处建议的MouseEvent
:
JTable auditTable = new JTable(){
//Implement table cell tool tips.
public String getToolTipText(MouseEvent e) {
String tip = null;
java.awt.Point p = e.getPoint();
int rowIndex = rowAtPoint(p);
int colIndex = columnAtPoint(p);
try {
tip = getValueAt(rowIndex, colIndex).toString();
} catch (RuntimeException e1) {
//catch null pointer exception if mouse is over an empty line
}
return tip;
}
};
