Derrell,
I looked at the code for the table model and it looks plausable to capture
the event qx.ui.table.ITableModel.EVENT_TYPE_META_DATA_CHANGED. However,
Fabians suggestion works perfectly and really is a better solution for me.
It allows me to capture the sort column number and the sort direction any
time either changes. Thanks to both of you. Here is my entire code that
subclasses the table model.
//
*****************************************************************************
// *
grfind.MyTableModel *
//
*****************************************************************************
qx.Class.define("grfind.MyTableModel",
{
extend : qx.ui.table.model.Simple,
//***********************************************************************
// CONSTRUCTION
*
//***********************************************************************
construct : function()
{
this.base(arguments);
var app = this.app = arguments[0]['app'];
},
/*
*****************************************************************************
PROPERTIES
*****************************************************************************
*/
properties :
{
sortIndex :
{
init : [-1,null], // [ integer - sortIndex , boolean - if
sort is ascending ]
event : "changeSortIndex"
}
},
//**************************************************************************
// MEMBERS
*
//**************************************************************************
members :
{
//
// sortByColumn
//
sortByColumn : function(columnIndex, ascending) {
this.base(arguments, columnIndex, ascending);
this.setSortIndex([columnIndex, ascending]);
}
}
});
// EOF
