With a unique combination of features, Magic Lane Maps and Navigation SDKs make real what developers have long sought: The places to be added to the map are MapItems. Thus, there are no methods or signals associated with the changes with the properties of position (for example, you cannot follow onAltitudeValidChanged signal of position). Rotation and translation works great, but I can't find a way to control the mouse position. That gives us windowPos. 0 import QtPositioning 5.

It looks like QML does not support calling the set method. pos() is a position in the parent, and this->mapToGlobal maps it relatively to this, not the parent, so simply said - you're mixing different coordinate systems - local and parent. These items shall be updated dependent of the position of a QSlider. They are easily convertible, and events like QMouseEvent offer both, local (pos()) and global (globalPos()) coordinates. The tiles are placed in a Grid class with nested Repeaters. what I want to do is to recenter my map with the following QML. In QML this is usually done with using a ButtonGroup, but as you're not using AbstractButtons you need to write it yourself. map. io The QChart class provides two methods that map between the scene coordinates and the series domain (defined by the axes ranges). The only thing I'd mention is that it's not common to use setters in QML; some systems (I believe they're called property interceptors) even rely on properties being set to perform animations, for example. Global coordinates are screen coordinates. Here is the strategy I have come up with. It should also be noted that the radius of MapCircle is in meters and not in pixels, I am currently trying to plot a large amount of items onto a QML Map (30,000 - 120,000 points).
