Get MouseEvents while MousePressed - qt

Question

I have several QML Items that all have Mouse Areas.
What I want to achieve is:
Click one of the items and start tracking the mouse
Add every other Item that the mouse enters into a list
End the tracking once the mouse is released
Sample Code:
import QtQuick 2.3
import QtQuick.Window 2.2
Window {
visible: true
width:500; height: 200;
Rectangle{
anchors.left: parent.left
color: 'red'
width: 200; height: 200;
MouseArea {
anchors.fill: parent
hoverEnabled: true
onReleased: console.log('onReleased red')
onEntered: console.log('onEntered red')
onPressed: {
console.log('onPressed red')
mouse.accepted = false
}
}
}
Rectangle{
anchors.right: parent.right
color: 'blue'
width: 200; height: 200;
MouseArea {
anchors.fill: parent
hoverEnabled: true
onReleased: console.log('onReleased blue')
onEntered: console.log('onEntered blue')
onPressed: console.log('onPressed blue')
}
}
}
Expected behaviour:
Click one Rectangle
Get on entered event if I enter the other element
Get the Released event
The sample code has both Version I tried, with and without accepting the mousePressed event.
What happens is:
If I press the mouse over one rectangle I do not get the onEnter event for all my other rectangles.
If I do not accept the onPressed event, I get the onEnter Events but not the onReleased event.
Note:
I already found this Answer which uses a DropArea as workaround which is not what I want to use if there is any other solution.
Even though the Example may look like Drag&Drop it is not what I want.
Please see the "What I want to achieve" at the top of this Question.

Answer 1

You will not be able to achieve what you want just using standart MouseArea components. Standart QML components are kinda limited in their functionality.
What you have to do is to create your own MouseArea component through QML extension.
In our project we also encountered lots of problems with mouse handling, so how we managed to do it was:
Subclassed QQuickItem, and inside of this class we just tracked the mouse movement, and mouse buttons states. One important thing wass to install EventFilters defined by this class.
In QML, created a Simple Component that Checks if mouse is inside of currrent component.
If you need, i could post also a code here so you have an idea.
The implementation is not the prettiest, but it works
