How are you forcing the redraw? If you are using setNeedsDisplayInRect:, are you expanding the rect enough to cover the shadow? On 5/22/13 4:34 AM, "cocoa-dev-requ...@lists.apple.com" wrote: > What bit of obviousness am I missing here? > http://www.sethwillits.com/temp/ShadowOffset.mov _

NSOutlineView View-based Layout issue

2013-05-13 Thread Gordon Apple
Outline View on right has a text field followed by a button near the right edge. Button strut is set on right. Initial layout is ok. Once any row is expanded, buttons get pushed to the right by row indentation. The only way to get it right is to expand width of containing window, then resize ba

NSOutlineView Storing/Restoring Disclosure Paths

We have a hierarchy, displayed in an NSOutlineView. We also allow the user to specify the root at any of the top two levels. When moving the root down the tree, if there is no selection, the new root is the first element of the top-level tree. If rows are selected, we use the first index path to

Our view-based NSOutlineView still has a few annomalies, but mostly works. Now, we are attempting to install a hoverView in our outline column to launch a popover (display only) when mousing over a row. This works just fine with NSTableViews, but so far does not work at all with NSOutlineView. We

We had assumed that outlineView:objectValueForTableColumn:item was not called if the table was bound to a NSTreeController. Wrong assumption. If we returned the correct value, or just eliminated this method, it mostly works correctly. However, there a few anomalies. The outline text indents prop

We are converting tables and outlines to view-based. So far, so good, on tables. But NSOutlineView has been a pain. First of all, there is no documentation on this, zero, zip, nada, zilch, in the NSOutlineView Reference. You have to rely on sample code and NSOutlineView.h. Our outline view has

Don¹t use NSMatrix. Use NSCollectionView. I have a popover containing a collection view with sliders and all kinds of other stuff. Depending on what you are doing, you may need to make the thing create a new view for every collection class element instead of just replicating the prototype. (I ha
