QML and Qt Quick

@Psyduck0205 I too facing similar issue. I need to access list of qvariant from squish? Can you help me ?

Hi, You can take a look at the fortune example for a way of generating random text.

ugh. I guess this feature has just been broken for over a year with misleading documentation. no big deal. thanks for your help everybody. https://bugreports.qt.io/browse/QTBUG-86132

Ok, I figured it out ! The shader does not change the Image, it just draws something else on the shader item's position. The solution was pretty darn simple: make the Image invisible and let the shadereffect item handle all the rendering part.

Yes QList<QObject*> is working. But why QList<SENSOR*> work on my Desktop and not work on raspberry???

@DiegOne hmm, still rather strange

@fcarney I removed the Component but the error is the same: QML PropertyAnimation: Cannot animate non-existent property "y" But now the Item should have the y property, right?

It would appear to be that there is an environment variable that will do this, not perfectly, but certainly vastly better than previously. Sadly, the very limited documentation on it implies it is only something for development purposes, presenting a clumsy way to look at your app using different DPI settings. The following, placed in main.cpp, worked. Yes, it could be set in the environment as well, having first tested it as a .profile entry. qputenv("QT_FONT_DPI", QByteArray("96")); 96 DPI is just a reference value on which Qt should be doing the appropriate scaling internally. It could be almost anything and still achieve the same results. Virtual pixels are obviously used for GUI components, why not consistently for the fonts. Though we are seeing what appears like a font substitution as well. Best guess is that Arial is being substituted for Liberation Sans, even though Liberation Sans is installed on all systems and is specifically loaded by the application. For example, the zero is much narrower on my system than on the target, as is the case of the zero in Arial as opposed to Liberation Sans.

This is really informative.

I've worked around this by putting the Popup in a separate qml file and using a Loader to get a fresh Popup every time I want to display it. But it still seems broken that a Popup can't be open/closed multiple times and have the BusyIndicator just continue to work.

Hi, Are you sure that the backend plugins are built ? Did you set them up properly in your .pro file ?

Anyone, please?

@markusme said in How to create a Calendar with newer QtQuick?: How do I create a Calendar in newer (2.x) version of QtQuick?? Fresh install with Qt version 5.15 and nothing online works. Just huge amounts of old and outdated tutorials on the Qt website. Just to be sure, I hope your are talking about Qt Kit version not Qt Version used to build Qt Creator (like the screenshot posted by @Markkyboy ) Did you select the right kit in Qt Maintenance tool? For example for Windows 32 bits: [image: b24febf8-59fe-4cbb-a66e-c3ef8e5f06f1.png]
