number, numberList, float and floatList default to rounding to three decimal places for display in the field. If you want more or less precision, add “:#” to the value type where “#” is an integer.

footer A list of item descriptions defining items to place below the table. footer should be formatted as the content argument when creating a HorizontalStack. An additional“gravity”` key may be used in the item descriptions to define where the item should align in the footer.

"leading"

editCallback The callback to call when an item is edited. Use the table’s identifier + "EditCallback" as the expected callback name.

setSelectedItems(items): Set the selected items in the list.

Note

setSelectedIndexes is the recommended method for setting selection. setSelectedItems is a convenience method that relies on iteration and comparing object ids to find the item indexes, which are then sent to setSelectedIndexes. If the list contains a large number of items this iteration can create a performance problem.

getSelectedIndexes(): Get a list of indexes of selected items in the list.

setSelectedIndexes(indexes)

Set the selected indexes in the list.

indexes should be a list of indexes.

scrollToSelection(): Scroll the selected rows to visible.

show(onOff)

Show or hide the object.

onOff A boolean value representing if the object should be shown or not.

Description Data

All of the description data of Table is allowed, except for dragSettings and dropSettings.

acceptedDropFileTypes The file types this table should accept from a drop. These must begin with a . For example, `[“.designspace”, “.ttx”]

acceptedDropPasteboardTypes The accepted pasteboard types this table should accept from a drop. These can be NSPasteboardType objects, vanilla values ("fileURL", "string", "plist"). Custom pasteboard types are also allowed. If any values are given for acceptedDropFileTypes "fileURL" will be automatically added to acceptedDropPasteboardTypes.

itemType The abstract type of item that the table will contain. The options are "object" and “dict“. This value instructs the table on how to get values from the item. "object" will use attributes and "dict" will use the dict-like key/value model. If the itemType is "object", each item must have a path attribute. If the itemType is "dict" each item must have a path key/value pair.

columnDescriptions The standard Table column desicriptions. There is a special column description that can be used to show the item’s path:

dict(
    identifier="path",
    cellDescripion=dict(
        cellClassArguments=dict(
            showFullPath=False,
            truncationMode="middle"
        )
    )
)

showFullPath A boolean indicating if the full path should be shown or just the file name.
truncationMode A string indicating the preferred text truncation mode. The options are "clipping", "head", "tail", "middle".

allowsDropBetweenRows A boolean indicating if dropping items between rows should honor the insertion point of the drop.

allowsInternalDropReordering A boolean indicating if the items in the table can be reordered with drag and drop.

allowsDragOut A boolean indicating if items in this table can be dragged and dropped somewhere else.

createItemsForDroppedPathsCallback The callback to be used when file pathss are dropped onto the table. This method must return items of the type defined in itemType. Use the table’s identifier + "CreateItemsForDroppedPathsCallback" as the callback name.

def myTableCreateItemsForDroppedPathsCallback(self, sender, paths):
    documents = [
        OpenMyDocument(path)
        for path in paths
    ]
    return documents

makeDragDataCallback The callback to be used to pack the items dragged out of the table. This must return a dictionary of form: { pasteboard type : value} where value must be a structure that can be stored in a plist. Use the table’s identifier + "MakeDragDataCallback" as the callback name. This callback is optional and is only needed when creating custom data types.

def myTableMakeDragDataCallback(self, sender, index):
    item = sender.get()[index]
    value = {
        "com.example.type.identifier" : item.asDict()
    }

filterItemsForImportCallback The callback to be used when unpacking dropped items to be added to the table. This must return a list of items ready to be added to the table. Use the table’s identifier + "FilterItemsForImportCallback" as the callback name. This callback is optional and is only needed in complex situations.

def myTableMakeDragDataCallback(self, sender, availableDataTypes):
    items = availableDataTypes["com.example.type.identifier"]
    return items

Description Data

All of the description data of FileTable is allowed, except for acceptedDropPasteboardTypes.

acceptedDropFileTypes This lists contains the file types you wish to accept as paths. If you don’t want to accept unopened fonts, leave this list empty.

columnDescriptions The standard Table column desicriptions. There are a special column descriptions that can be used to show general font info:

"path"
"name"
"familyName"
"styleName"

dict(
    identifier="name",
)

If allowsDragOut is True items dragged out of the table will be described on the “dev.robotools.fontParts.Font.Identifier” pasteboard. If you want to implement read/write on this pasteboard, the following protocols apply:

fontParts Dragging Protocol

The data placed on the pasteboard will be the id of the wrapped defcon object. The dragging source will need to return the fontParts objects that wrap the objects with the given ids in the getDropItemValues method. For example:

def getDropItemValues(self, items, pasteboardType=None):
    if pasteboardType == "dev.robotools.fontParts.Font.Identifier":
        idToFontParts = {id(obj.asDefcon()) : obj for obj in self.get()}
        fontPartsObjects = []
        for item in items:
            wantedID = item.propertyListForType_(pasteboardType)
            fontPartsObjects.append(idToFontParts[wantedID])
        return fontPartsObjects
    else:
        ...

handlers A list of handler identifiers. See addHandlerIdentifier() for details.

setHTML(html): Set HTML in the view.

setURL(url): Set the url in the HTMLView.

executeJavaScript(text): Execute JavaScript within the html in the view.

addHandlerIdentifier(identifier)

Add a handler identifier that will used to send messages to a callback from JavaScript within the HTML.

The identifier must be a string indicating the name of the handler to be used when sending messages back to your controller. Your controller must have a corresponding method with the name identifier + "Callback". Your JavaScript code should reference your identifier at the location noted by myHandlerIdentifier in this code:

window.webkit.messageHandlers.myHandlerIdentifier.postMessage("A message,");

The message sent through postMessage can be any string.
