QML and Qt Quick

Code here https://github.com/dangelog/qmllogging :)

[quote author="SGaist" date="1414014463"]Hi, Just a question but, would be xmlhttprequest suited for your needs ? You have an example "here":http://qt-project.org/doc/qt-5/qtqml-xmlhttprequest-example.html[/quote] That would exactly be the interface I need, but I want to make my own class. The http request was just an example, the goal is to do different request/reply functionality. For example remote procedure calls. I looked into the code of xmlhttprequest, but it's heavy javascript based. My goal is to have class useable from C++ and QML. Using the finished() signal of the accessManager is also an option, but this would require a big selector for the response function, if I want a special response function for every request.

Don't know for Linux but on OS X, it's working fine

Hi, I don't know if you solved, but I had same problem. The guide you followed uses the visual studio compiler, so I guess you set INCLUDE and LIB in qtcreator. In my case I had mingw so env variables I had to set were CPATH and LIBRARY_PATH

Hi, Thanks for reply. I can't add code to my post (is too long) so I've shared the code by html link. My code you can fiend "here":http://dshav.com/pub_pictures/code.html.

Thank you for the reply. I have something like this in my code: @ fileName = QFileDialog::getOpenFileName(this,tr("Open Enroll Image"),QDir::currentPath(),tr("Image Files [ *.jpg , *.jpeg , *.bmp , *.png , *.gif]")); if(!fileName.isEmpty()) { QImage imageE(fileName); … @ I think in fileName will be the full path, right? I tried also to run the exe files as administrator (maybe a permission issue) but the error persists. [edit: added missing coding tags @ SGaist]

As a commercial customer, you can ask the Qt Company / Digia and get professional support. Here is what I think: You need a static build of Qt itself Configure your build chain (Kit) so that this static build is used Then use both CONFIG += static and CONFIG += staticlib Compile It may work, although I'm not sure about the platform plugin

Glad that it worked :) Please mark the post as solved by editing the post title and prepend [solved]

One point to bookmark . Though, I have a work-around solution but I will investigate more. Thank you!

Since you can't use Qt Widgets in QML, what i meant earlier was you can load the Qt widgets normally and the QML using QQuickWidgets on the same form layout.

Yes, but the one placed in main.qml. I found the error meanwhile: on top of the LoginScreen.qml I wrote @import QtQuick.Controls 1.2@ This was wrong because my installed version has V 1.1 of the QtQuickl controls included, so I changed it to @import QtQuick.Controls 1.2@ and now everything works fine - I wonder why the Button and TextFields were showing properly in the Design View of LoginScreen.qml, though.

As I pointed out, grabWindow will include the window itself and will thus most likely be opaque and therefore not useful for the purpose of an AlphaMouseArea.

bq. Is there a limit on the number of singletons in one directory? I don't know. I suppose the limit is on the developper side since it's not so great to have a lot of singleton About the initial problem perhaps there is an order to follow. Since the last singleton use other ones, they must be created/available before the last one ???

Thank you very much my friend. It's work PRFECTLY !!! awesome work regards

Here you can find the debugging output with QSG_INFO=1: http://qt-project.org/forums/viewthread/48610/#199687 without I get no warnings.
