Subject: Re: [qooxdoo-devel] List - getSelectedItems()
Hi Raffi,
I know Lists and Tables are different, but here's the approach I use for
doing the same thing with a Table. Essentially, I iterate the selection
to create my own list of "selected indexes", and then manipulate that,
finally re-selecting the new positions based on their new indexes:
moveStepDown : function(ev){
var smodel = this.buildsteps_table.getSelectionModel();
var steps = this.dataObject.getSteps();
var selection = [];
smodel.iterateSelection(function(index) {
selection.push(index);
}, this );
if(selection.length === 0 || selection[ selection.length - 1]
=== (steps.length - 1) ){
return;
}
smodel.clearSelection();
for(var i = selection.length - 1; i >= 0; i--){
var tmp = steps[ selection[i] + 1 ];
steps[ selection[i] + 1 ] = steps[ selection[i] ];
steps[ selection[i] ] = tmp;
}
for(var i = 0, l = steps.length; i < l; i++){
steps[i].setOrderas( i );
}
this.redisplayBuildStepsTable();
for(var i = 0, l = selection.length; i < l; i++){
smodel.addSelectionInterval( selection[i] + 1,
selection[i] + 1);
}
},
Sincerely,
Mr. Hericus
