Qt6基于Qml的文件对话框演示效果

主界面如下 

 打开单个文件配置

FileDialog {
        id: idFileOpenOne
        fileMode: FileDialog.OpenFile
        nameFilters: ["Pictures (*.png *.jpg *.gif *.bmp)", "All (*.*)"]
        options :FileDialog.ReadOnly
    }

打开多个文件配置

FileDialog {
        id: idFileOpenMore
        fileMode: FileDialog.OpenFiles
        nameFilters: ["Pictures (*.png *.jpg *.gif *.bmp)", "All (*.*)"]
        options :FileDialog.ReadOnly
    }

保存文件配置

FileDialog {
        id: idFileSave
        nameFilters: ["Pictures (*.png *.jpg *.gif *.bmp)", "All (*.*)"]
        fileMode: FileDialog.SaveFile
    }

三个按钮布局

Row{
        anchors.centerIn: parent
        spacing: 30
        Button{
            text: qsTr("Open")
            height: 48
            width: 120
            MouseArea{
                anchors.fill: parent
                onClicked: {
                   idFileOpenOne.open();
                }
            }
        }
        Button{
            text: qsTr("Open More ...")
            height: 48
            width: 120
            MouseArea{
                anchors.fill: parent
                onClicked: {
                    idFileOpenMore.open();
                }
            }
        }
        Button{
            text: qsTr("Save")
            height: 48
            width: 120
            MouseArea{
                anchors.fill: parent
                onClicked: {
                    idFileSave.open();
                }
            }
        }
