QML and Qt Quick

I did some experiments and I think partially the problem is with ESRI map server did not response, or did not response fast enough. When I switch to Google plugin, the problem is not exactly go away, but the tiles do show or show up faster...

Hi @niqt, I haven't done this before, but you can check this out: https://developers.arcgis.com/qt/10-2/qml/api-reference/class_wms_dynamic_map_service_layer.html

My researching lead me to the following point: looks like that issue consist of videodrivers and opengl. I have situation when my application craches approximately 1 of 3 times. The machine where problem was occured has internal video card on motherboard Gigabyte h55m-s2, I have tried to change drivers and get the strange behavior, when application starts well, but colors are not normal. So I will continue my investigation to this direction.

I solved this issue by adding explicit dragActive property to the MouseArea. Sample code: MouseArea { id: mouseArea drag { target: myItem axis: Drag.YAxis } property bool dragActive: drag.active onDragActiveChanged: { if(drag.active) { // ... // Dragging started } else { ... // Dragging finished } } }

Thanks, had similar bug with target being undefined: "Unable to assign [undefined] to QObject*" Fixed according to the Qt doc: https://doc.qt.io/qt-5/qml-qtqml-connections.html#target-prop If set to null, no connection is made and any signal handlers are ignored until the target is not null. Connections { // If set to null, no connection is made and // any signal handlers are ignored until the target is not null. target: myItem ? myItem : null onPropertyChanged: { ... } }

I managed to include the path to swift libraries as dir with the following flags in my .pri file: # set additional Library directory for swift support QMAKE_LIBDIR += \ /usr/lib/swift \ # adding "Runtime Search Paths" for swift support QMAKE_RPATHDIR += \ /usr/lib/swift \ "Always Embed Swift binaries" seems not to be needed, my app compiles and is executable.

@J-Hilk Thank you. Let me try and let you know the feedback.

As I mentioned, I would like to play with any style, so I guess I'm not able to hardcode use of Material style.

@raven-worx Thank you for your help, now I can move forward my project.

@J-Hilk I managed the required behavior, somehow. By blanking the key value: stg.setValue("step_1", "") then scanning the keys, which have non-empty value, and skipping the empty ones. I'll file a bug, cause I think it's a needed method! By the way, thank you all

@Lelouche said in Error to create QML project: on reports to me an error in emulation and creation of the puppet. What puppet and what error?

Found It! Had to change the folder structure a.k.a. main.qrc to qml.qrc

use file selectors for showing completely different UI https://doc.qt.io/qt-5/qfileselector.html#adding-selectors You can also add extra selectors at runtime for custom behavior. These will be used in any future calls to select(). If the extra selectors list has been changed, calls to select() will use the new list and may return differently.

Did you saw the third argument of the signal ? The one you are currently not using in the code you provided. It's the one containing the custom roles.
