gridview

开始时使用flow布局，ajax请求的图片闪烁，后来改用gridview解决问题

GridView {

                    cellWidth: 200

                    cellHeight: 150

                    model: contactModel

                    delegate: Column {

                        width: 200

                        height: 150

                        Image {

                            width: parent.width

                            horizontalAlignment: Image.AlignHCenter

                            sourceSize.height: 100

                            fillMode: Image.PreserveAspectFit

                            source: imgurl

                            Text {

                                anchors.bottomMargin: 30

                                width: parent.width

                                anchors.top: parent.bottom

                                horizontalAlignment: Text.AlignHCenter

                                font.pointSize: 10

                                text: name

                            }

                        }

                    }

                }
