well, its not trivial with GridView. You might need to use model to
filteredmodel sorting manually, or implement model in C++ with methods
you need

Andrey, makes sense.
It is an model which is not related to the file system.
Instead, it contains strings like caption and url and few booleans
such as isFavourite and isActive.
I would like to use the mentioned booleans, to filter out elements is
a SilicaGridView.

I am wondering how I could display a single ListModel in multiple
SilicaGridViews (filtered)?
Simply making an item invisible in a specific view does not work,
because it still consumes (cellWidth x cellHeight) the space.
I know, I could also implement my own model in c++. Probably
something like this was done my someone already?
Currently, I am experimenting with multiple models which I need to
keep in sync (implementation is far from ready ;)).
[FilteredListModel.qml]
import QtQuick 2.0
import Sailfish.Silica 1.0
Item {
property ListModel filteredModel: _filteredModel
property ListModel model: _model
property string filterRoleName
property var filterValue
ListModel {
id: _filteredModel
}
ListModel {
id: _model
onRowsInserted: {
for (var i = first; i <= last; i++) {
var entry = model.get(i);
if (entry[filterRoleName] === filterValue)
{
_filteredModel.append(entry);
}
}
}
onRowsRemoved: {
for (var i = first; i <= last; i++) {
_filteredModel.remove(i);
}
}
}
function append(sobject)
{
model.append(sobject);
}
function setProperty(index, key, value )
{
model.setProperty(index, key, value);
var entry = model.get(index);
if (entry[filterRoleName] === filterValue)
{
_filteredModel.set(index, model.get(index))
}
else
{
_filteredModel.remove(index);
}
}
function remove(index)
{
model.remove(index);
}
Component.onCompleted: {
model.append({"name": "Apple","cost": 0.25,active: false});
model.append({"name": "Orange","cost": 0.90,active: true});
model.append({"name": "Bannana","cost": 0.30,active: true});
model.append({"name": "Ananas","cost": 3.10,active: true});
}
}
