JTable 在 combobox 的幫助下選擇？

Question

I have a combobox with values of 1 to 5 and a JTable of 5X5... Whenever a select a value from combobox corresponding entire column of the JTable has to get selected... how do I proceed with this...

Answer 1

首先，您需要配置表以允許列選擇：

table.setColumnSelectionAllowed( true );
table.setRowSelectionAllowed( false );

然后對於組合框，您需要根據所選項目索引將 ActionListener 添加到 select 列：

table.setColumnSelectionInverval(...);

Answer 2

獲取 combobox 中選中項的值為comboBox.getSelectedItem()並解析為 integer 然后調用以下方法：

public void getSelected(int comboBoxValue){
    table.setSelectionMode(ListSelectionModel.MULTIPLE_INTERVAL_SELECTION);

    // The following column selection method works 
    // only if these properties are set
    table.setColumnSelectionAllowed(true);
    table.setRowSelectionAllowed(false);

    table.setColumnSelectionInterval(comboBoxValue, comboBoxValue);
}
