QML Camera问题
写了一个小demo，功能是实现Camera的自动截图。程序能正常运行，但是发现Image无法显示中文路径的图片。望高手指点。
代码如下：
- import QtQuick 2.9
import QtQuick.Window 2.2
import QtMultimedia 5.8
Window {
visible: true
width: 640
height: 480
title: qsTr("Camera")
property int btnHeight: 50
Camera {
id: camera
}
VideoOutput {
anchors.fill: parent
source: camera
}
Column {
anchors.top: parent.top
anchors.right: parent.right
anchors.bottom: parent.bottom
anchors.bottomMargin: listView.height
anchors.margins: 10
width: 120
spacing: 9
Rectangle {
id: takePhotoRect
width: parent.width
height: btnHeight
color: "darkgray"
border.width: 2
border.color: "white"
Text {
anchors.centerIn: parent
text: qsTr("Take Photo")
font.bold: true
}
MouseArea {
anchors.fill: parent
onClicked: {
camera.imageCapture.capture()
}
}
}
Rectangle {
id: playSequence
width: parent.width
height: btnHeight
color: "darkgray"
border.width: 2
border.color: "white"
Text {
anchors.centerIn: parent
text: qsTr("Play Sequence")
font.bold: true
}
MouseArea {
anchors.fill: parent
onClicked: {
}
}
}
Rectangle {
id: clearSequence
width: parent.width
height: btnHeight
color: "darkgray"
border.width: 2
border.color: "white"
Text {
anchors.centerIn: parent
text: qsTr("Clear Sequence")
font.bold: true
}
MouseArea {
anchors.fill: parent
onClicked: {
}
}
}
}
ListView {
id: listView
anchors.left: parent.left
anchors.right: parent.right
anchors.bottom: parent.bottom
width: parent.width
height: 50
orientation: ListView.Horizontal
model: imgPathsModel
delegate: Image {
width: 50
height: 50
source: imgPath
}
}
ListModel {
id: imgPathsModel
}
Connections {
target: camera.imageCapture
onImageSaved: {
console.log("path:", path)
imgPathsModel.append({"imgPath": path})
}
}
}
点击“Take Photo”按钮后，本地文件生成相应的图片文件，但是ListView里的Image显示报错。如下：
