JTable - 激活列數據更改事件

Question

我想激發一個事件，該事件表示給定的列值已全部更改，即列X中的某處，某些值已更改。我如何能做到這一點，因爲所有的事件無論是關注單元格，行或整個數據表......在AbstractTableModel

Answer 1

看，它看起來像構建TableModelEvent明確可能做的伎倆：

model.fireTableChanged(new TableModelEvent(model, 0, lastRow, columnIndex, 
         TableModelEvent.UPDATE)); 

參見對於TableModelEvent的Javadoc：

/** 
* Depending on the parameters used in the constructors, the TableModelevent 
* can be used to specify the following types of changes: <p> 
* 
* <pre> 
* TableModelEvent(source);    // The data, ie. all rows changed 
* TableModelEvent(source, HEADER_ROW); // Structure change, reallocate TableColumns 
* TableModelEvent(source, 1);   // Row 1 changed 
* TableModelEvent(source, 3, 6);  // Rows 3 to 6 inclusive changed 
* TableModelEvent(source, 2, 2, 6);  // Cell at (2, 6) changed 
* TableModelEvent(source, 3, 6, ALL_COLUMNS, INSERT); // Rows (3, 6) were inserted 
* TableModelEvent(source, 3, 6, ALL_COLUMNS, DELETE); // Rows (3, 6) were deleted 
* </pre> 
* 
* It is possible to use other combinations of the parameters, not all of them 
* are meaningful. (...)

個人而言，我只希望觸發一個事件地說，如果它只是指示所需刷新表整個表發生了變化。
