Is it necessary to subclass NSTableView or NSTableCellView to create a custom drag image when the tableView is the drag source? If not, what is the magic method I am missing to do this? I cannot seem to find anything solid. NSTableCellView subclasses have can (slightly mysteriously) override: @property(retain, readonly) NSArray *draggingImageComponents (array of NSDraggingImageComponent instances that will get composited together (who knows in what fashion they get composited...)) NSTableView itself has - (NSImage *)dragImageForRowsWithIndexes:(NSIndexSet *)dragRows tableColumns:(NSArray *

I have an NSTableView that has a very small fixed number of rows. When I create an NSTableView in Interface Builder, the NSTableView is contained within an NSScrollView . I have not found a way to make the table exist outside the context of a scroll view. Since the table only has a small number of rows, I don't want it to scroll. I want the table to resize based on the number of rows, and I want the bottom border immediately under the bottom of the last row. If I set the height of the scroll view as follows, I get a vertical scroll bar: height = (numRows * (rowHeight + intercellSpacingHeight))

I have a NSTableView with one column. I would like to print the row number of the row that the user has clicked on. I am not sure where I should start with this. Is there a method for this? You can use the selectedRowIndexes property from the tableView in the tableViewSelectionDidChange method in your NSTableView delegate. In this example, the tableView allows multiple selection. Swift 3 func tableViewSelectionDidChange(_ notification: Notification) { if let myTable = notification.object as? NSTableView { // we create an [Int] array from the index set let selected = myTable.selectedRowIndexes

How do I go about drawing my own custom selection style for a view based NSTableView ? I tried putting a BOOL var in my NSTableCellView subclass and set that to YES if it is clicked and then I can successfully draw my custom selection. But how do I change that BOOL var to NO when another view is clicked? Thanks for any help. EDIT: After reading through the NSTableView docs, it looks like I need to subclass NSTableRowView to override the selection drawing, but what do I do with my NSTableRowView subclass? How do I get the table to use it? Alright, I figured it out. You just have to subclass

I am working through a Cocoa in Swift book and I am stuck in a chapter on Bindings. The book uses nib files but I want to do everything programmatically (since I am joining a team that does not use nibs). The project is to create a view based table with 2 columns and the content of the table is bound to the arrangedObjects of an array controller. The array controller's content is bound to an array of Employee objects (Employee has 2 properties viz. name and salary). I was able to create the table programmatically like below (one scroll view, one table view, 2 table columns): let tableWidth =

Basically, I have an NSTableView with 1 collumn, and I'm inserting long strings into each row. However, not all the strings are long, so I'd like the height of each row to be different based on how long the string is. I've figured out that I need to ask the collumn how wide it is, and then ask the string how many lines it will take up if the collumn is that wide, and then decide how "tall" the NSCell will be. But how exactly do I go about doing that? I've gotten the collumn width from: [[[tableView tableColumns] objectAtIndex:0] width]; but I can't figure out how to ask the NSString how much
