QML and Qt Quick

@raven-worx Thanks for the guide I was able to fix the problem with the below code Flickable { id : flickable x: 0 y: 0 width: parent.width height: 425 contentHeight: rectangle.height contentWidth: rectangle.width clip: true ScrollBar.vertical: ScrollBar { width: 40 policy: ScrollBar.AlwaysOn parent: flickable.parent anchors.top: flickable.top anchors.left: flickable.left anchors.bottom: flickable.bottom }

@fcarney I appreciate the response but this didn't work for me. This however, led me to look further into the documentation. I was aware of smooth, anti-aliasing, and sourceSize which I all tried and didn't work. Solution The solution in the end was mipmap: true on the image, which results back to a smooth image. This is default to false, and I didn't realise that scaling the image down would produce a bad quality image but turns out, yes.

@fcarney perfect that's exactly what I needed! my bad, I didn't go to the bottom of the documentation... Yes QML Image loads perfectly this kind of url: content://com.android.providers.media.documents/document/image%3A455947 So I'm just storing it as a string and do the test in QML rather than in C++. No need of an hidden image, it can be done directly on the visible one with something like this: Image { id: dogPicture fillMode: Image.PreserveAspectFit; height: parent.height/2 - 8* spacing source: dog.pictureUrl anchors { top: parent.top topMargin : spacing horizontalCenter: parent.horizontalCenter } onStatusChanged: if (status === Image.Error) source = dog.dogIconDefault(); } with my C++ accessor being: QString Dog::pictureUrl() const { if (_pictureUrl.isEmpty()) return sDogIconDefault; return QUrl(_pictureUrl).toString(); } Thanks @fcarney ;)

Solved it by adding the line qputenv("QT_STYLE_OVERRIDE","Material"); in main.cpp

@jsulm I reported it just now. https://bugreports.qt.io/browse/QTBUG-100159

Thank you very much. It works fine now.

Finally found MapItemView which does what I am searching for.

Taken directly from the 5.15.8 docs for DisplaySettings: ========================================== Detailed Description There is no need to create an instance of this object. To use it, simply import the QtDeviceUtilities.DisplaySettings module. ========================================== But where is it? Why does it not exist for Windows? We have a commercial license. Where is this documented functionality? What is required to insure that the install of Qt that we are using includes the required library/module? In an operating room, setting the brightness is a very valuable capability. And, yes, I know what a singleton is, having created numerous singletons for this project.

It's documented in the QML Reference : https://doc.qt.io/qt-5/qtqml-syntax-objectattributes.html#property-attributes

@Narahara said in undefined reference to library function in Qtcreator: And I use a library developed by Visual Studio 201 Is this library a C++ library? If so then you have to use compiler from Visual Studio 2013 to build your app, because you can't mix binaries compiled with different compilers.

@RLocksley said in project.exe does not launch: windeployqt project.exe if that is the whole command you used, that you missed the --qmldir parameter https://doc.qt.io/qt-5/windows-deployment.html

@ekkescorner I worked on that and now it supports much more formats. Currently it's a PR opened, but it should be soon merged: https://github.com/scytheStudio/SCodes/pull/11 Sorry that I add the comment to a quite old post. I simply wanted people to know it and not be misled.
