QML and Qt Quick

Right way is to write model in pure C++. QQmlListModel is internal class, so you can not use it from C++.

Someone can help me? Selection doesn't work for the TextInput and TextAreaInput even when it's not read only. this is a bug ?! how can I solve this problem ?

This is actually not currently supported by TableView. However it is not all that hard to do yourself. I made an example spreadsheet to give you an idea: @import QtQuick 2.2 import QtQuick.Layouts 1.1 import QtQuick.Controls 1.1 TableView { id: table model: 100 width: 600 height: 400 TableViewColumn { } TableViewColumn { } TableViewColumn { } TableViewColumn { } property int currentColumn: 0 Keys.onRightPressed: if (currentColumn < table.columnCount - 1) currentColumn++; Keys.onLeftPressed: if (currentColumn > 0) currentColumn--; rowDelegate: Rectangle { // grid height: 20 color: "#fff" } itemDelegate: Rectangle { property bool selected: styleData.row === table.currentRow && styleData.column === currentColumn color: "transparent" Rectangle { anchors.fill: parent color: selected ? "#4488ee" : "transparent" } Label { id: label verticalAlignment: Text.AlignVCenter anchors.leftMargin: 4 anchors.rightMargin: 4 anchors.fill: parent elide: Text.ElideRight text: styleData.value color: selected ? "white" : "black" } Rectangle { anchors.right: parent.right height: parent.height ; width: 1 color: selected ? "transparent" : "#eee" } Rectangle { width: parent.width ; height: 1 color: selected ? "transparent" : "#eee" } MouseArea { anchors.fill: parent onClicked: { currentColumn = styleData.column currentRow = styleData.row table.forceActiveFocus(); } } } } @

Hi, thanks it works now, here is the code @import QtQuick 2.2 import QtQuick.Layouts 1.1 import QtQuick.Controls 1.1 ApplicationWindow { minimumHeight: 100 maximumHeight: 300 minimumWidth: 100 maximumWidth: 300 width: 300 height: 300 Rectangle { id: rectangle anchors.fill: parent onWidthChanged: console.log("Rectangle Width : "+width) ColumnLayout { anchors.fill: parent // Doesn't work with that //width: 100 // Works with that onWidthChanged: console.log("Column Width : "+width) Rectangle { color: "red" onWidthChanged: console.log("Rectangle 1 Width : "+width) Layout.fillHeight: true // Doesn't extend Layout.fillWidth: true // Doesn't extend Layout.minimumHeight: 50 Layout.maximumHeight: 100 } Rectangle { color: "green" //width: rectangle.width height: 100 onWidthChanged: console.log("Rectangle 2 Width : "+width) Layout.fillHeight: true // Doesn't extend Layout.fillWidth: true // Doesn't extend Layout.minimumHeight: 50 Layout.maximumHeight: 100 } Rectangle { color: "blue" onWidthChanged: console.log("Rectangle 3 Width : "+width) Layout.fillHeight: true // Doesn't extend Layout.fillWidth: true // Doesn't extend Layout.minimumHeight: 50 } } } } @

Hi, Please take the time searching the forum. This question comes almost every week. Have a look a this well written "wiki entry":http://qt-project.org/wiki/Deploy_an_Application_on_Windows for windows deployment. You also have the "Windows Deployment Guide":http://qt-project.org/doc/qt-5.0/qtdoc/deployment-windows.html

Thanks, I will check it out.

I solved using QApplication in the main.cpp. I used the header from the Gallery example. @ #ifndef QTQUICKCONTROLSAPPLICATION_H #define QTQUICKCONTROLSAPPLICATION_H #ifdef QT_WIDGETS_LIB #include <QtWidgets/QApplication> #else #include <QtGui/QGuiApplication> #endif QT_BEGIN_NAMESPACE #ifdef QT_WIDGETS_LIB #define QtQuickControlsApplication QApplication #else #define QtQuickControlsApplication QGuiApplication #endif QT_END_NAMESPACE #endif // QTQUICKCONTROLSAPPLICATION_H @ and in the main.cpp @ QtQuickControlsApplication app(argc, argv); @ I also added this line in the .pro file @ !android: !ios: !blackberry: qtHaveModule(widgets): QT += widgets @ But they are not actually needed :) Thanks for the help guys!!

Sorry, I forgot to do that :D

Hi, that what i thought i will have to do it by myself or use qwt. Thanks for your answers

That's it http://developer.blackberry.com/native/documentation/cascades/dev/integrating_cpp_qml/

Dynamic array is from STL or Qt?

This is understandable - QtQuick 1 and 2 are completely separate beasts and require different designer rendering helpers.

Tnx a lot 4 answer! ok, but my app will be run at mac os, etc, where Android API will not be available, and what next? About C++ version, i think i can't use is so maybe some one know other libs or some service or something other solutions?

went image provider route, seems the best/only real way. ( i also needed some resizing code for when the source is larger than the element, to downsize it

[quote author="MrBolton" date="1400665764"]But I'm still wondering: Does the QQuickWidget not support QtQuick 1 at all?[/quote] Correct. It does not need to (plus, QtQuick 1 is deprecated in Qt 5).

Nice, so now we know for sure :-)

I have gstreamer-0.10 and its plugins on my machine. When I run the gstreamer from shell I can see the rtsp streaming.

First of all, below shows how to instantiate your cpp objects in qml @ import my.app.MyQObject 1.0 item { MyQObject { id:obj } } @ I thought Object.create will work, but no. Second, in QML apparently your MyQObject, as well as other QML elements all have type of object. it doesn't even have prototype.. so it behaves sortof like a builtin object If you need reflection, check objectName property. Any exported QObject will have that property by default. This seems the case since Qt 5.0 So instead of typeof(obj), use obj["objectName"]

Thanks lack! Your example about JavaScript behavior is reasonable. I use Binding to update C++ properties automatically. In my example, puppy is actually a C++ object while input is a Qt Quick TextField. Whenever input.text changes, QML will call puppy.name's WRITE method, e.g. setName(input.text). But if name was mispelled, QML will have nothing to call and in my opinion should output a warning, just like when Qt complains about a non-existent signal/slot.
