Re: [Interest] Unable to make deb file of Qt 5.5 app in Ubuntu 14.04

Hi, I guess that this is the same issue that I had already. This happens because Ubuntu uses QT_PLUGIN_PATH set in the system. Try to set this environment variable somewhere in the shell and run/build you application. Something like this: export QT_PLUGIN_PATH= for example in bashrc and

Re: [Interest] Import C++ types to Javascript

If your object is not a singleton you will need to create an instance to call the function on that object. I suggestion you keep your staticfunction call into a singleton. So you don't need an instance. > On Nov 27, 2015, at 8:11 PM, Jason H wrote: > > I just checked, it is a

Re: [Interest] Any plans to bring back/provide a replacement for GestureArea

While each of those components provides some of the functionality that I need, they are not as well suited as GestureArea. This is due to the fact that I want to support multiple gestures on a custom QQuickItem: tap, tapAndHold, pan (one finger drag), pinch (two finger drag). This is rather

Re: [Interest] Any plans to bring back/provide a replacement for GestureArea

Hi Peter, I think the functionality of the type was split among MouseArea, PinchArea and MultiPointTouchArea . Take a look at them and see if they fit your use case. Bests, F. On 27

[Interest] Any plans to bring back/provide a replacement for GestureArea

Hello, I could really use a QML element that can detect arbitrary gestures. It seems that in Qt4, GestureArea used to do just that: http://doc.qt.io/qt-4.8/qml-gesturearea.html However, it appears that in Qt5, it has been removed. What was the rationale for that? Are there any chances of it

This is not my tree, it's a simple webpage/webform. But it seems that the new "webengine" can't handle simple tasks like this. I don't think that the following statement is too complex: document.getElementsByTagName('input') Best regards > Am 25.11.2015 um 13:08 schrieb Koehne Kai
