ZipFileInfo QML Type

The ZipFileInfo component provides information about a .ZIP compressed file. More...

Import Statement: import ArcGIS.AppFramework 1.0



Detailed Description

The ZipFileInfo component reads and returns file information about a zip archive and its contents. It works similarly to the FileInfo component, but is only capable of reading zip archives and their contents.

This is a read-only component; it contains no capability to write to or alter any details of a compressed file, it can only read them.

This code sample demonstrates using multiple properties obtained through ZipFileInfo to provide a console log of a zip archive's contents.

Item {
        ZipReader {

        Button {
                text:"Zip FileInfo"
                        var zipfileinfo = zipreader.fileInfo("qt.txt")
                        console.log(("The file %1 within the zip file has a compressed size of %2 bytes
                        and was last modified at %3").arg(zipfileinfo.fileName).arg(zipfileinfo.compressedSize).arg(zipfileinfo.lastModified))
