c++ - Qt Maps (QML) application window is blank -

-

this code qt maps application i'm trying make. http://pastebin.com/pncyivm9 - main.qml

i'm using qt creator on ubuntu 14.04. when compile , run code application window blank.

i haven't edited main.ui.qml apart adding qt location import.

i've added location keyword in .pro file appreciated since can't find tutorials on maps.

edit: here's code

import qtquick 2.4 import qtquick.controls 1.3 import qtquick.window 2.2 import qtquick.dialogs 1.2 import qtlocation 5.4  applicationwindow {     title: qstr("hello world")     width: 640     height: 480     visible: true       plugin{         id: osmplugin         name:"osm"     }      map {         plugin: osmplugin          id: map         zoomlevel: (maximumzoomlevel - minimumzoomlevel)/2   //        center { //            latitude: -27.5796 //            longitude: 153.1003 //        }          // enable pinch gestures zoom in , out         gesture.flickdeceleration: 3000         gesture.enabled: true  //    center { //        latitude: -27.5796 //        longitude: 153.1003 //    }     }     }

your map has no dimensions set, it's going default width , height of zero. see case, add following map component:

component.oncompleted: {     console.log("dimensions: ", width, height) }

this print out:

dimensions: 0 0

so either need set dimensions value other zero, or use anchor property attach dimensions parent's anchors.
