MouseEvents not delivering to internalMouseAreas QML 1.1 TouchScreen

Sfatima

Hi
i am developing on a touch Screen, but i have a particular problem for QML 1.1 where my generated MouseEvents are not being delivered to internal MouseAreas of a QML file. The outerMouseArea captures event but does not send it internally

Qt Code: Switch view
Rectangle {
id: screen;

   /* Content */
width: 800;
height: 480;

Rectangle{
    id:header
    width: 300
    height: 42
    color: "blue"
    anchors.right: parent.right
    anchors.bottom: parent.bottom
    anchors.rightMargin: 10
    anchors.bottomMargin: 10

    MouseArea{
    id: headerMouse
    width: header.width
    height: header.height
    x: header.x
    y: header.y


     onEntered:
     {
        console.log("on Entered");
        console.log("mouseArea x", x);
        console.log("mouseArea y", y);
        console.log("mouseArea width", width);
        console.log("mouseArea height", height);
     }
     onPressed:
     {
      console.log("onClicked inside X", mouseX);
      console.log("onClicked inside Y", mouseY);
      mouse.accepted = false;
     }
   }

}

 Rectangle{
    id:header2
    width: 300
    height: 42
    color: "yellow"
    anchors.left: parent.left
    anchors.leftMargin: 10
    anchors.top: parent.top
    anchors.topMargin: 10


    MouseArea{
    id: header2Mouse
    width: header2.width
    height: header2.height
    x: header2.x
    y: header2.y


     onEntered:
     {
        console.log("on Entered in header 2");
        console.log("mouseArea x", x);
        console.log("mouseArea y", y);
        console.log("mouseArea width", width);
        console.log("mouseArea height", height);
     }
     onPressed:
     {
      console.log("onClicked inside header 2", mouseX);
      console.log("onClicked inside header 2", mouseY);
      mouse.accepted = false;
     }
   }

}

MouseArea
{
anchors.fill: parent
onEntered:
{
console.log("area parent X", mouseX);
console.log("area parent Y", mouseY);
}

 }
 onPressed:
 {
     mouse.accepted = false;
 }

}
}

I am using seperate thread to generate MouseEvents
Qt Code: Switch view
QCursor::setPos(position.x, position.y);
QPoint absoluteWidgetPosition = d->getViewer()->mapToGlobal(QPoint(0, 0));
int relativeX = position.x - absoluteWidgetPosition.x();
int relativeY = position.y - absoluteWidgetPosition.y();

if(newState == PANEL_RELEASED)
{
    qApp->postEvent(view, new QMouseEvent(QEvent::MouseButtonRelease, QPoint(relativeX,relativeY), Qt::LeftButton, Qt::LeftButton, Qt::NoModifier));

    qDebug() << "QEvent::MouseButtonPress Panel released: x" << relativeX << "y:" << relativeY;
}
else if(newState ==PANEL_PRESSED)
{
    qApp->postEvent(view, new QMouseEvent(QEvent::MouseButtonPress, QPoint(relativeX,relativeY), Qt::LeftButton, Qt::LeftButton, Qt::NoModifier));

    qDebug() << "QEvent::MouseButtonPress Panel pressed: x" << relativeX << "y:" << relativeY ;
}

I am capturing events in a derived class of QtQuick1ApplicationViewe
Qt Code: Switch view
#include "myview.h"
#include "qdebug.h"

MyView::MyView(QWidget *parent) :
QtQuick1ApplicationViewer(parent)
{
}

bool MyView::event(QEvent *e)
{
if((e->type() == QEvent::MouseButtonPress) ||
(e->type() == QEvent::MouseButtonRelease))
return QWidget::event(e);
else
return QtQuick1ApplicationViewer::event(e);

}

void MyView::mousePressEvent(QMouseEvent *evt)
{
qDebug() << "MouseEvent Press type" << evt->type();

QtQuick1ApplicationViewer::mousePressEvent(evt);

}

void MyView::mouseReleaseEvent(QMouseEvent *evt)
{
qDebug() << "MouseEvent Release type" << evt->type();

QtQuick1ApplicationViewer::mouseReleaseEvent(evt);

}

Can anyone tell what the problem is. Thanks in advance.

Hi @Sfatima,
I don't know about Qt Quick 1.1 but in Qt Quick 2.0 and onwards you have propagateComposedEvents. Setting it allows the mouse events to propagate to other areas.
BTW QtQuick 1.x is deprecated now.
