• Expanding all items of a NSOutlineView that loads data from a data source

  - by matei

  First of all I'm new to cocoa development so I suppose I'm probably trying to do this the wrong way, but here goes: I have a NSOutlineView which loads the data from a NSOutlineViewDataSource imnplementation. I want all the items to be expanded after they are loaded, but i can't seem to find an event fired when the data has finished loading, so I can send a [outlineView expandItem:nil expandChildren: YES] to it. I looked into the NSOutlineViewDelegate protocol but I was unable to find a sutable place for this call. What would be the best approach for this problem ?

• NSOutlineview - strange behavior after reloading data

  - by matei

  I have a NSOutlineView which loads data from a data source. The table is displayed in a panel. The items shown in the table are items which belong to an object (the relation is one-to many between the object and the items). I have a list of objects in a combo box (in fact a NSPopupButton), and when I select another object in the combo box, I want it's items to be shown in the table (the NSOutlineView). I managed to do all this , however when I select another object from the combo box, not all of it's items are displayed. I have put some logging messages in the data source and it seems that there are some items that are being returned from the data source , but are not shown in the table (and are not queried for children). Now the strange part is that when I click the main window (as I said, all that I described here is in a NSPanel loaded on top of the window) , all the data is displayed correctly. It seems as if clicking the main window triggers something in the NSOutlineView that makes it display the missing items, but I can't tell what it is.

• NSOutlineView/NSTreeController - calculate sum of column

  - by matei

  I have a NSOutlineView bound to a NSTreeController. My data items are a custom class , let's call them "Row", and suppose a Row contains a "name" and a numeric field called "number" . All these "Rows" are found in let's say a "RowContainer" which has a "rows" mutable array holding the parent (level 0) rows. Each row also has a "children" NSMutableArray member which holds it's children. I have this working, and I want to display under the outlineview a textfield with the sum of all the "number" values of the rows. I bound this textfield to a "total" property of the "RowContainer". Now the problem is how or from where to trigger the recalculation of the "total" property, since this involves a recursive walk on the tree of rows, and I always get a "Collection was mutated while being enumerated" error. I've tried making a method "recalculateTotal", and calling it from the "setNumber" method of the "Row" class , but same error occurs. If I put the recalculation logic in the "total" getter, I can't trigger it to do the math. I'm sure the solution is simple but I can't see it

• NSOutlineViewDelegate - need something like didFinishEditing

  - by matei

  NSOutlineViewDelegate has outlineView:shouldEditTableColumn:item: which gets called before editing a cell. I need a similar method called after the user has finished editing a cell (in order to trigger some calculations). Where should I look for this event ?
