Re: [Qt-qml] How to ignore MouseArea signals
Hello,
Is there a reason why accepted isn't handled in the other mouse events?
Cheers,
Jerome P.

Log a bug. It would be good if you could suggest where the docs are lacking
- i.e. where you started looking when this didn't work as expected. The
accepted behavior is documented in the MouseArea signal documentation.

Woo, OnPressed works, thanks very much.
The document need to be improved. Any process to do that?
Cheers,
Halton.

You need to accept in onPressed. accepted is ignored for any other event.

enabled does not match my case.
I need receive the MouseArea signals but as well as those below the top
item can receive the signals also.
Refer to MouseEvent element document, seems accepted can do that.
-
accepted : bool
Setting accepted to true prevents the mouse event from being propagated
to items below this item.
Generally, if the item acts on the mouse event then it should be
accepted so that items lower in the stacking order do not also respond
to the same event.
But following code does not work as I wish
MouseArea {
anchors.fill: parent
onClicked: {
console.log(mouse.accepted=+mouse.accepted)
mouse.accepted = false
console.log(mouse.accepted=+mouse.accepted)
}
}
Thanks,
Halton.

You can set enabled property to false or ignore the event on mouse
press.
MouseArea {
anchors.fill: parent
onClicked: console.log(background clicked);
}
MouseArea {
anchors.fill: parent
enabled: false
//onPressed: mouse.accepted = false;
onClicked: console.log(foreground clicked);
}

Re: [Qt-qml] How QML file is parsed and linked and executed?
Hello,
Example:
import QtQuick 1.0
Rectangle {
id:screen; width: 100; height: 100
Rectangle {
id: one; width: 10; height: 10
Component.onCompleted: console.log(one)
}
Rectangle {
id: two; width: 10; height: 10
Component.onCompleted: console.log(two)
}
Rectangle {
id: three; width: 10; height: 10
Component.onCompleted: console.log(three)
}
Component.onCompleted: console.log(screen)
}
=
output:
screen
three
two
one
The top level's handler is first, then the children.
Is this a reasonable generalization to make?
Cheers,
Jerome P.

Hi,
As it says in the documentation, the order Component.onCompleted handlers are
executed is not defined.
Roughly speaking (as there are exceptions), elements are instantiated from top
to bottom, and the onCompleted signals are executed in reverse order of
instantiation. But don't rely on that behaviour.
Cheers,
Aaron

Hi,
as you all know HTML and JavaScript are executed / or evaluated / form the TOP
to BOTTOM. So if you have a source of 100 lines it will start from line 1 and
will finish with the last one. When you know this you can somehow figure our
some tricks you want to make and know what to expect.
I have a QML file that I want to trace how it's reacting.
Rectangle {onCompleted: {console.col(m1)}}
Rectangle {onCompleted: {console.col(m2)}}
and in the console output I have m2, m1.
so does it mean that in QML we have stack popup priority of structure handling
- you parse it from top to bottom and execute it form bottom to top? does it
mean that my later element will always have Component.onCompleted before?
Or this reverse order is just temporary or coincidence on my machine or we
shall not expect any order of loading - everything will come when it comes?
Best Regards,
Ivo

Re: [Qt-qml] FocusScope and Positioning
Hello,
Thanks for your reply.
I will add this information as usage guideline in the focus document.
Currently, there isn't any content regarding how to use the FocusScope element.
Thanks,

Subject: Re: [Qt-qml] FocusScope and Positioning
Hi Jerome,
FocusScope is considered a visual element (like Item, it is a visual element
that doesn't actually draw anything) with a geometry, so it needs an explicit
size (e.g. binding its size to its children's size) to work properly within a
layout. It certainly wouldn't hurt to make that more explicit in the docs -- is
that something you are happy to do along with your other revisions in this area?
Regards,
Michael

Hello,
I am revising the focus document and I noticed something unexpected.
Here is a sample code:
import QtQuick 1.0
Rectangle {
width: 200; height: 200
Column {
FocusScope {
Rectangle {width: 50; height: 50; color: blue}
}
FocusScope {
Rectangle {width: 50; height: 50; color: red}
}
}
}
What I would like is to place these two FocusScope on top of each other,
instead the rectangles will be in front of each other.
Removing the FocusScope element will do what I intended, but the addition of
a FocusScope doesn't behave as (I, at least) expected.
This issue might come up when people start wrapping their components in
FocusScopes and the element which imports these components may
not be aware of these FocusScope behaviors.
Any workarounds?
Cheers,
Jerome P.
