我是QT的新手，我学会了通过连接列表模型来使用网格视图 . 我想将活动的观看图像限制为4而不是列表模型中的所有项目
Rectangle {
id: Rect1;
width: 1280; height: 720;
ListModel {
id: listAssetModel
ListElement { Movie: "Arrow"; PosterURL: "posters/Arrow.jpg" }
ListElement { Movie: "Avatar"; PosterURL: "posters/Avatar.jpg" }
ListElement { Movie: "Avenge"; PosterURL: "posters/Avenge.jpg" }
ListElement { Movie: "Arrow"; PosterURL: "posters/Arrow.jpg" }
ListElement { Movie: "Avatar"; PosterURL: "posters/Avatar.jpg" }
ListElement { Movie: "Avenge"; PosterURL: "posters/Avenge.jpg" }
ListElement { Movie: "Arrow"; PosterURL: "posters/Arrow.jpg" }
ListElement { Movie: "Avatar"; PosterURL: "posters/Avatar.jpg" }
ListElement { Movie: "Avenge"; PosterURL: "posters/Avenge.jpg" }
}
GridView {
id: gridAssetPreview;
currentIndex: -1 // default - no focus on poster
x: 56; y: 189
width: 1140; height: 300
focus: true
cellWidth: 275; cellHeight: 300 // keeps the poster preview images aligned
highlight: appHighlight
model: listAssetModel
delegate: appDelegate
}
Component {
id: appDelegate
Item {
width: 250; height: 350 // controls the appHighlight size
Image {
id: imgPosterPreview
width: 225; height: 325
source: PosterURL
smooth: true
}
Text {
id: textAssetName
anchors { // draw this below and centre to the image
top: imgPosterPreview.bottom;
horizontalCenter: imgPosterPreview.horizontalCenter
}
text: AssetName
font.pointSize: 16
color:"white"
smooth: true
}
}
}
}
网格视图区域定义如下，但它似乎在运行时显示多行图像，这不是我所期望的 . 我只想在整个1280 x 720屏幕上看到4个图像 . 宽度：1140;身高：300
请帮忙，我在周日坚持这个:-(
