[SOLVED] Get qml signals

chaf84

Hi
I have a problem to connect to my qml signals. I have a qdeclarative view that have main.qml as source. I use a qdeclarativeitem and qdeclarativecomponent to add new qml items to the declarative view. My qml signals is in the components that are added to the declarativeview. Does the rootobject get signals from my added qml item? Are there a way for the added qml item to pass the signals to rootobject?

This is my set up
QDeclarative view
-Main.qml

QDeclarativeItem is added to view->rootobject
QDeclarativeItem
-testHelper.qml (Its here where the signals are)

Main.qml
@Rectangle {
id: container
width: 800
height: 600
color: "white"
}@

Qml file for item where the signals are.
@
import QtQuick 1.1

Rectangle {
id: rect
objectName: "Button"
signal newPositionSignal(string position)
signal deleteSignal(string objectName)
signal selectedSignal(string objectName)

onNewPositionSignal: {
console.log('newPositionSignal: ' + position);
}

onDeleteSignal: {
console.log('deleteSignal: object "' + objectName + '"" deleted');
}
onSelectedSignal: {
console.log('selectedSignal: object "'+ rect.objectName + '"" selected');
content.border.color = "blue"
}

Rectangle {
id: content

width: childrenRect.width
height: childrenRect.height
border.color: "black"
border.width: 2
color: "transparent"

Component.onCompleted: {
var component = Qt.createComponent("../Indicators/TankLevel.qml");
if (component.status === Component.Ready) {
var button = component.createObject(content);
}
}

MouseArea {
id: contentMouseArea
anchors.fill: parent
drag.target: parent
onClicked: {
rect.selectedSignal(rect.objectName);
}
onReleased: {
rect.newPositionSignal(rect.objectName+','+ parent.x+','+ parent.y+','+ parent.z);
}
}
}

Rectangle {
id: remove
width: 20
height: 20
color: "black"
anchors.right: content.right
anchors.top: content.top

Text {
anchors.centerIn: parent
text: "X"
color: "white"
}

MouseArea {
anchors.fill: parent
onClicked: {
rect.deleteSignal(rect.objectName);
rect.destroy();
}
}
}
}

Setting up declarativeview
@
qmlPath = path;
view = new QDeclarativeView(this);
view->setSource(QUrl::fromLocalFile(path));

view->setResizeMode(QDeclarativeView::SizeViewToRootObject);

viewerManager vManager(cMan);
vManager.setRootObject(view->rootObject());
QObject::connect(view->engine(), SIGNAL(quit()), view, SLOT(close()));

@

Function for inserting item to the view
@
QDeclarativeComponent testcomponent(view->engine());
testcomponent.loadUrl(QUrl::fromLocalFile("testHelper.qml"));
QDeclarativeItem* testcomp = qobject_cast<QDeclarativeItem *>(testcomponent.create());
testcomp->setParent(view->rootObject());
testcomp->setParentItem(qobject_cast<QDeclarativeItem *>(view->rootObject()));
QDeclarativeEngine::setObjectOwnership(testcomp, QDeclarativeEngine::JavaScriptOwnership);
@

Class that handles qml signals
@
viewerManager::viewerManager(QObject *parent) :
QObject(parent), mRoot(0)
{
}

viewerManager::viewerManager(componentManager *component, QObject *parent) :
QObject(parent), mRoot(0)
{
mComponent = component;
}

void viewerManager::setRootObject(QObject *root){
if (mRoot != 0) disconnect(mRoot);

mRoot = root;

if(mRoot){
    connect(root, SIGNAL(newPositionSignal(QString)), this, SLOT(newPositionSignal(QString)));
}

}
void viewerManager::newPositionSignal(QString pos){
qWarning() << "Got signal";
}

I solved the issue, I connected the signals in when I added the declarativecomponent.

@
QDeclarativeComponent testcomponent(view->engine());
testcomponent.loadUrl(QUrl::fromLocalFile("testHelper.qml"));
QDeclarativeItem* testcomp = qobject_cast<QDeclarativeItem *>
(testcomponent.create());
//Added all signals here
QObject::connect(testcomp,SIGNAL(test()),this,SLOT(test()));

testcomp->setParent(view->rootObject());
testcomp->setParentItem(qobject_cast<QDeclarativeItem *>(view->rootObject()));
QDeclarativeEngine::setObjectOwnership(testcomp, QDeclarativeEngine::JavaScriptOwnership);
