Mouse area overlapping

? Offline

I'm having this problem too. Here's the code:

@ImagemHover {
nome: "buscar"
anchors.horizontalCenter: bola.horizontalCenter
anchors.bottom: bola.bottom
anchors.bottomMargin: -20
}

Bola {
id: bola
color: "gray"
width: 128; height: 128
anchors.centerIn: parent
imagem: "img/fotos/eu.jpg"

MouseArea {
    anchors.fill: parent
    anchors.margins: -25
    hoverEnabled: true

    onEntered: { bola_hover = true }
    onExited: { bola_hover = false }
}

}@

And here's the code for the ImagemHover:

@import Qt 4.7

Image {
property string nome: "buscar"
source: "img/"+ nome +"_normal.png"

opacity: bola_hover ? 1 : 0
Behavior on opacity { PropertyAnimation {} }

Image {
    id: hover
    source: "img/"+ nome +"_hover.png"
    opacity: 0
    Behavior on opacity { PropertyAnimation {} }
}

MouseArea {
    anchors.fill: parent
    hoverEnabled: true

    onEntered: { hover.opacity = 1 }
    onExited: { hover.opacity = 0 }
}

}
@

As you can see, the ImagemHover is under Bola, so it's mouse area isn't having effect, because Bola's MouseArea is over it..

How can I work with this overlapping problem?

puelocesar, as I know there is no solution now for overlapping mouse areas, but I think changing z-order of items will help you in your case.

I need to change a little ImageHover logic, but now it's working. Thanks

puelocesar, you've changed z-order or you have done something other? If second it will be good if you can post the solution

My problem was: I have a circle, and when the circle mouse overs, a set of options appear above the circle.

So, when I moused over the Circle, I set the options opacity to 1, showing them. And when I moused over one of the options, that were inside the circle, the option would change it's color to orange.

But the mouse area's of the options and the circle were overlapping, so it wasn't working.

The solution was to put the Circle's MouseArea under the options (z-order), and adding the logic that was only on circle's mousearea inside the options mouseareas. So the overlapping wasn't a problem anymore.

Is this making any sense? it was very difficult to explain that without drawing :P

Resuming, I changed the z order of the circle, and changed this on ImagemHover:

@import Qt 4.7

Image {
property string nome: "buscar"
property bool hover: false
source: "img/"+ nome +"_normal.png"

opacity: bola_hover ? 1 : 0
Behavior on opacity { PropertyAnimation {} }

Image {
    id: hover
    source: "img/"+ nome +"_hover.png"
    opacity: 0
    Behavior on opacity { PropertyAnimation {} }
}

MouseArea {
    anchors.fill: parent
    hoverEnabled: true

    onEntered: { hover.opacity = 1; bola_hover = true }
    onExited: { hover.opacity = 0; bola_hover = false }
}

}

has anyone ever documented the double mouse area problem to nokia?

DenisKormalev

kyleplattner, yes, it was discussed somewhere here at DevNet.

hhartz

But was it logged as a bug report? Please do so or assume it remains lost and undiscovered :)
