[英]how to get value from ticked jcheckbox in a row from jtable
I have a table with 3 column and dynamic row based from database value and a jcheckbox in last column based on this code : 我有一个表,该表具有基于数据库值的三列和动态行,并且基于此代码在最后一列中有一个jcheckbox:
TableColumn tcolumn = tabel.getColumnModel().getColumn(2);
tcolumn.setCellRenderer(tabel.getDefaultRenderer(Boolean.class));
tcolumn.setCellEditor(tabel.getDefaultEditor(Boolean.class));
example of my table: 我的桌子的例子:
============================================
val 1 || val 2 || val 3 (checkbox) ||
============================================
from FB || from DB || checkbox ||
from DB || from DB || checkbox ||
===========================================
My question is simple, how can I get all of the value 1 from the ticked checkbox in column 2 (value 3)? 我的问题很简单,如何从第2列(值3)的复选框中得到所有的值1?
I tried many simple code but still got an error. 我尝试了许多简单的代码,但仍然出现错误。
this is my code: 这是我的代码:
for (int row =0; row <= tabel.getSelectedRowCount(); row++) {
Boolean b = ((Boolean) tblModel.getValueAt(row, 2));
if (b.booleanValue()) {
System.out.print(tblModel.getValueAt(row, 0)+" || ");
}
}
It's not clear what error you get or where you get it; 目前尚不清楚您会得到什么错误或在哪里得到的错误。 I suspect an error casting to
Boolean
. 我怀疑将错误转换为
Boolean
。 As general guidance, the default renderer and editor for Boolean.class
is a JCheckbox
; 作为一般指导,
Boolean.class
的默认渲染器和编辑器是JCheckbox
。 you shouldn't have to set it explicitly. 您不必显式设置它。 As shown here , ensure that you observe the following principles for your cast to succeed:
如图所示这里 ,请确保您遵守以下原则,你的施法成功:
Insert values of type Boolean.class
in your TableModel
. 在
TableModel
插入Boolean.class
类型的值。
Return Boolean.class
from getColumnClass()
for the relevant column. 从
getColumnClass()
返回相关列的Boolean.class
。
Return the desired value from isCellEditable()
. 从
isCellEditable()
返回所需的值。
