remove xmlns:android="http://schemas.android.com/apk/res/android" <fragment> element, , consider moving xmlns:map="http://schemas.android.com/apk/res-auto" <fragment> element root element.

for example, valid:

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:map="http://schemas.android.com/apk/res-auto"     android:id="@+id/foo"     android:layout_width="match_parent"     android:layout_height="match_parent">      <fragment         android:id="@+id/map"         android:layout_width="match_parent"         android:layout_height="match_parent"         class="com.google.android.gms.maps.supportmapfragment"         map:maptype="satellite"/>  </relativelayout>

Image
i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
