QML and Qt Quick

OK I will try your suggestion. Thank you all the same.

What I've ended up with is @ Component.onCompleted: { width = modelData.duration * pixelSecondWidth x = modelData.seconds * pixelSecondWidth + 1 } Connections { target: modelData onDurationChanged: { if (!mouse.drag.active) { property.width = modelData.duration * pixelSecondWidth } } onSecondsChanged: { if (!mouse.drag.active) { property.x = modelData.seconds * pixelSecondWidth + 1 } } } onWidthChanged: { if(mouse.drag.active) modelData.duration = width / pixelSecondWidth } onXChanged: { if (mouse.drag.active) modelData.seconds = (x - 1) / pixelSecondWidth } @ I figure there must be a way to do this with Bindings somehow. May play around later. Thinking something like: @ Binding on width { when: mouse.drag.active; value: ...} @

Well it looks like my last post was deleted when the server went down last night, so let me sum it up. The problem was my javascript was originally in my QML file, in 'Component.onCompleted: {CODE WAS HERE}', in my javascript code I had a multiline quote such as this: @ Qt.createQmlObject(' DYNAMICALLY GENERATED QML GOES HERE ', parent, myObject); @ When I copied and pasted the javascript into it's own file I needed to escape the literal newlines such as this: @ Qt.createQmlObject(' DYNAMICALLY GENERATED QML GOES HERE ', parent, myObject); @ And that sums it up - _ -

You can always create your own widget and export it to QML.... I don't think it is possible to reimplement functions on existing QML-Widgets etc...

“go out of state” is known "change from state1 to state2". in onStateChange() know state2, but not know state1. not need making other pages invisible because default value of PropertyChanges.restoreEntryValues is true.

Question be solved,a ha...

Hey, let me google that for you: "link":http://lmgtfy.com/?q=qml+graph.

Yes..Sure.Thanks a lot

Short example @ import QtQuick 2.0 Rectangle { width: 300 height: 200 color : "#ddf" ListView { anchors.fill: parent interactive: false model : ListModel { // nodes ListElement { nx:50; ny:100; } // node position is (nx, ny) ListElement { nx:150; ny:50; } ListElement { nx:250; ny:100; } ListElement { nx:150; ny:150; } } delegate : Item { x:0; y:0; width:0; height:0 // here is the "trick" Rectangle { x: nx; y:ny; width:10; height:10; radius: 5; border.color: "#113" MouseArea { anchors.fill: parent; drag.target: parent; } } } } } @

Here how I solve your problem... @import QtQuick 2.0 Rectangle { id: rootTarget width: 800 height: 800 DropArea { id: dragTarget1 property alias dropProxy: dragTarget1 width: 200; height: 200 y: 100; x: 100 Rectangle { id: target anchors.fill: parent color: "lightgreen" } states: [ State { when: dragTarget1.containsDrag PropertyChanges { target: target color: "green" } } ] } DropArea { id: dragTarget2 width: 200; height: 200 y: 400; x: 100 Rectangle { id: target2 anchors.fill: parent color: "lightgreen" } states: [ State { when: dragTarget2.containsDrag PropertyChanges { target: target2 color: "green" } } ] } Rectangle { id: debut width: 120; height: 120 x: 600; y: 600 color: "red" MouseArea { id: maDrag drag.target: carre width: 100; height: 100 anchors.centerIn: parent onReleased: { console.log('onReleased') parent = carre.Drag.target !== null ? carre.Drag.target : debut } Rectangle { id: carre color: "blue" width: 100; height: 100 anchors.verticalCenter: parent.verticalCenter anchors.horizontalCenter: parent.horizontalCenter Drag.active: maDrag.drag.active Drag.source: maDrag Drag.hotSpot.x: width/2 Drag.hotSpot.y: height/2 states: [ State { when: maDrag.drag.active PropertyChanges { target: carre opacity: 0.5 } ParentChange { target: carre parent: debut } AnchorChanges { target: carre; anchors.horizontalCenter: undefined; anchors.verticalCenter: undefined } } ] } } } }@

GridView does not seem to handle visual grouping and sections as ListView does. On the other hand, laying items in a grid in a ListView might not be so straight-forward.

Thanks. Yes, there is more code, not relevant to this issue. When I show all, it becomes hard to read/find the relevant code. Meanwhile I have made some more signal/functions. They all generate errors, but they do work. I have the feeling that is some kind timing problem. First, the variable cannot be found, and possibly it is instantiated or resolved just a split second later... But I am just guessing here.

It works now, maybe a Windows restart was needed. Anyway thanks for your help.

Hey Thanks we can close this one as solved, I filed a bug report. Your right forums are bad places to post bugs. I will likely post if asking if someone gets similar behaviour and then file a bug report. Anyways heres the report if your interested I will likely post more bugs as I go along https://bugreports.qt-project.org/browse/QTBUG-31359 thanks again!

Yeah got the same issue here

Aha. So, I'll create one main.qml with the specific UI pages based on components and use visible as switch. Thanks.
