Change separator color to background or remove it from NSTableView

Question

I am looking to remove the separator color in View based NSTableView.

It looks like this :

enter image description here

For UITableView there is a method setSeparatorColor: but not for NSTableView.

Solutions will be highly appreciated.

@Harikrishnan: already checked but that only didn't work for me, I had to increase the viewSize as well. — Anoop Vaidya, May 06 '13 at 10:33

I did this as:

Changed the Intercell spacing to :

[aTableView setIntercellSpacing:NSMakeSize(0, 0)];

And changed the height of the the cell, set view's width to 30.f , the cell being drawn is of 35.f.

Now it is perfect, screen shot :

For NSTableView, Interface Builder has settings for Horizontal Grid, Vertical Grid, and Grid Color. These are reflected in the API as -setGridStyleMask and setGridColor.

They do exactly what you want.

[table setGridColor:[NSColor clearColor]];
[table setGridStyleMask:NSTableViewGridNone];

I wanted transparent color. – Anoop Vaidya May 06 '13 at 09:59
If you set the grid to none, the only color will be your background color, just as you asked for. If you had wanted it to be another color, you could of course set it to a different partially transparent colour. Any colour can have a transparency set (alpha). – Steve Waddicor May 06 '13 at 10:19
I checked with this way, still it shows in view based tableview :( – Anoop Vaidya May 06 '13 at 10:22
OK, I tested this out with a view based table. Cocoa draws the grid on top of the table cell. So the only colour that would make the grid disappear would be 0% alpha. But setting the grid to none doesn't draw the grid at all, so that can't be visible. So it could only be that it was gaps between the views that were showing for you (but not me). I guess that's why intercell spacing and/or changing the height of your cell views worked for you. – Steve Waddicor May 06 '13 at 10:35
not only intercell, i had to implement both (increaed the view height too) – Anoop Vaidya May 06 '13 at 10:37

Maybe I could mention that in view based tables NSTableRowView is responsible for drawing the seperators. So in the inspector for the table you set it the grid to "None" and implement drawSeparatorInRect: in your NSTableRowView subclass, which in your case would mean leaving it empty.

yes your point of subclassing is correct. But I did it without that overhead. As you have seen in my solution. – Anoop Vaidya May 06 '13 at 11:43

If you turn off grid views in an NSTableView, drawSeparatorInRect: doesn't get called. – Aaron Vegh Aug 31 '13 at 14:33
