Hi list,
I want to [ have to ;) ] change my table (model) dynamically during run-time.
The table does show 7 or 5 columns depending on an external switch.
What I did is creating my own RemoteTableModel that should handle this, but I
always get into problems when the "new" column count is less than the one
before. (I guess the columnModelRenderer does still want to render/access the
last 2 columns...)
What I'm currently doin' in my remoteTableModel is something like this:
----------------------- *snip * --------------------
qx.Class.define("app.foo.remoteTableModel",
{
extend : qx.ui.table.model.Remote,
//...
properties :
{
/** The different table formats. */
format :
{
check : [ "full", "basic" ],
init : "full",
apply : "_applyFormat"
}
},
members :
{
headers : {
full : {
names : [ "One", "Two", "Three", "Four", "Five", "Six", "Seven" ],
ids : [ 0, 3, 4, 5, 6, 1, 2 ] // backend data is kind o' shuffled ;)
},
basic : {
names : [ "Column A", "Column B", "Column C", "Column D", "Column E" ],
ids : [ 0, 1, 2, 3, 4 ]
}
},
//...
_applyFormat : function(value, old)
{
if (value != old) {
this.reloadData(); //... from the backend
this.setColumns( this.headers[value].names, this.headers[value].ids );
//
for (var i=0,l=this.headers[value].ids.length; i<l; ++i) {
this.setColumnSortable(i, true);
}
}
}
//...
}
//...
}
----------------------- *snip * --------------------
But this seems not to work 100% ...
Is this the way I should continue, or do I have to completely remove and
re-instantiate my table?
What is the best way to do it?
Searching the list, I only found this:

...is this still valid with qooxdoo 0.7 ?
