swing - text field in jTable something better than ActionPerformed(java.awt.event.ActionEvent evt)! -
hi guys hope well.. day have question again using text field in jtable edit column , use model.getvalueat(); column , model.setvalueat(); column after doing calculations fanaly when press enter key action replays not reply , not update changing have press again... code looks this:
private void txt_actionperformed(java.awt.event.actionevent evt){ try { int viewrow = table.getselectedrow(); string id = (table.getmodel().getvalueat(viewrow, 1).tostring()); string sql1 = "select * mydb.mytable_1 id1='"+id1+"'"; dm.pst = dm.c.preparestatement(sql1); dm.rs = dm.pst.executequery(); if (dm.rs.next()) { float = dm.rs.getfloat("mycolumn_1"); float b = float.parsefloat(model.getvalueat(viewrow, model.getcolumncount()-10).tostring()); float c = float.parsefloat(model.getvalueat(viewrow, model.getcolumncount()-9).tostring()); string d = model.getvalueat(viewrow, model.getcolumncount()-8).tostring(); float e = 0; switch (d) { case "u":case "1":e = 0;break; case "w":case "2":e = 7;break; case "x":case "3":e = 10;break; case "y":case "4":e = 14;break; case "z":case "5":e = 20;break; default:system.err.println("error..");break; } if(b>a){ joptionpane.showmessagedialog(null, "b bigger a..!!"); }else if(a>=b){ float val_1 = a-b float val_2 = b * c; float val_3 = b * (((e / 100) + 1) * c); model.setvalueat(val_3, viewrow, model.getcolumncount()-6); model.setvalueat(val_2, viewrow, model.getcolumncount()-7); model.setvalueat(val_1, viewrow, model.getcolumncount()-11); string id2 = (table.getmodel().getvalueat(viewrow, 0).tostring()); string upid = "update mydb.mytable_2 set mycolumn_2='" + b + "'where id2='" + id2 + "'"; dm.pst = dm.c.preparestatement(upid); dm.pst.execute(); } } } catch (exception ex) { joptionpane.showmessagedialog(null, ex); } }
anything else better action performed? note: after edited code using jtextfield txt_ = new jtextfield(); editor column , using model = new defaulttablemodel() thank in advance
i using text field in jtable edit column , use model.getvalueat(); column , model.setvalueat(); column
don't use actionlistener.
your logic should defined in tablemodel
@override public void setvalueat(object value, int row, int column) { super.setvalueat(...); if (column == ?) // add logic here calculation , update other column value }
