Unable to dynamically change KDE Plasma 5 Widget Expandable FullRepresentation Component size outside of Component.onCompleted - qml

Question

I'm coding a widget that can be expanded to its FullRepresentation by being clicked on:
onClicked: {
plasmoid.expanded = !plasmoid.expanded
}
I have a function that updates its contents and puts them into a Gridview. The update function is first called from Component.onCompleted, but then I call it every time the user updates the data. The problem is the data I feed into the expandable FullRepresentation can contain a varying number of elements that I put into the gridview and calculate its AND the FullRepresentation's sizes based on this number.
However, I find I'm only able to specify the Representation's size from the Component.onCompleted block. When I call the update function outside it, it doesn't change the size, no matter whether the size is defined in the item properties like so:
Item
{
id: fullRepresentation
width: no_items > 2 ? 465 : no_items * 155
height: Math.ceil(no_items / 3)* 155
property int no_items
...and I only try to change the no_items property from the UpdateFunction, or just try to run the two equations from it.
Is there any way around this? I've also tried the implicitHeight and implicitWidth properties. I really would like to be able to dynamically adjust the size of the main expandable representation, it feels bad to have to hardcode it and then have a lot of unfilled space.
EDIT:
Here is the requested example:
Root.qml
import org.kde.plasma.plasmoid 2.0
import QtQuick 2.2
Item
{
id: root
width: 185; height: 185
Plasmoid.compactRepresentation: Compact {}
Plasmoid.fullRepresentation: Full {}
Plasmoid.preferredRepresentation: Plasmoid.compactRepresentation
signal addItems()
}
Compact.qml
import QtQuick 2.2
Item
{
Rectangle
{
width: root.width; height: root.height
MouseArea
{
anchors.fill: parent
acceptedButtons: Qt.LeftButton | Qt.RightButton
onClicked: if (mouse.button == Qt.RightButton) root.addItems()
else plasmoid.expanded = !plasmoid.expanded
}
}
}
Full.qml
import QtQuick 2.2
Item
{
width: no_items > 2 ? 465 : no_items * 155
height: Math.ceil(no_items / 3)* 155
property int no_items : 0
function redrawGridView()
{
readingListModel.clear()
var i
for (i = 0; i < no_items; i++) readingListModel.append({})
}
function addItems()
{
no_items = 6
width = no_items > 2 ? 465 : no_items * 155
height = Math.ceil(no_items / 3)* 155
redrawGridView()
}
ListModel
{
id: readingListModel
}
GridView
{
id: readingGridView
width: count > 2 ? 465 : count * 155
height: Math.ceil(count/3) * 155
cellWidth: 155; cellHeight: 155
model: readingListModel
delegate: Rectangle
{
width: 150; height: 150;
}
}
Component.onCompleted:
{
root.addItems.connect(addItems)
no_items = 3
redrawGridView()
}
}

Well, I got no answer but I've figured this out myself.
Indeed, this doesn't seem to be possible using the plasmoid.expanded method with the Full Representation, and produces other bugs, as I mentioned in my comment.
But you can dynamically resize a Window item size from anywhere in your code, so this works just fine:
in Compact.qml
Full
{
id: fullRep
}
MouseArea
{
anchors.fill: parent
onClicked:
{
if (!fullRep.visible) fullRep.show()
else fullRep.close()
}
}
start of Full.qml
Window
{
x: 100;y: 100
width: 465;height: 195
color: theme.backgroundColor
flags: Qt.FramelessWindowHint //You can make it frameless like the expandable
//representation is when using the previous method
