详细描述

The FolderDialog type provides a QML API for native platform folder dialogs.

To show a folder dialog, construct an instance of FolderDialog, set the desired properties, and call open ()。 currentFolder property can be used to determine the folder that is currently being displayed in the dialog. The selectedFolder property can be used to determine the last folder that was selected in the dialog.

MenuItem {
    text: qsTr("Open...")
    onTriggered: folderDialog.open()
}
FolderDialog {
    id: folderDialog
    currentFolder: StandardPaths.standardLocations(StandardPaths.PicturesLocation)[0]
    selectedFolder: viewer.folder
}
MyViewer {
    id: viewer
    folder: folderDialog.selectedFolder
}

Available options:

This property holds the last folder that was selected in the dialog.

The value of this property is updated each time the user selects a folder in the dialog, and when the dialog is accepted. Alternatively, the accepted () signal can be handled to get the final selection.
