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();
                }
            }
        }
    }
