Date: Sun 06-Apr-1989 03:01:32 From: Unknown Subject: new question: multiple selection in a Matrix Thanks to those people who pointed me at the runModalFor: method in the Application class. If you want to make a miscellaneous panel run modally, you just need to do: [NXApp runModalFor:myPanel]; to invoke it and when your panel wants to return control back it should do: [NXApp stopModal]; You do not need to do: [myPanel orderFront:self]; since runModalFor: will do that for you. I remembered there was a runModal method, but I forgot what class it was in... I was tracing up classes from Panel and basically barking up the wrong tree. Here's a new problem, possibly tougher. I have an NX_LISTMODE matrix in which I would like to select cells. Unfortunately, it seems that selectCellAt:: deselects the previous selected cell. What I would like to do is have the same effect as dragging the mouse across multiple cells, shift-mouse, and command-mouse. More specifically, I would like to add a cell to the current selection when I select programmatically; I'll clearSelectedCell when I want to zap the old selection. Part of the problem is that I really don't understand what selecting multiple cells does internally. There is only a single selected row/column in the Matrix. sendAction:to:forAllCells: implies that all it is is highlighting, but I discovered that "selecting" via to select a single cell via the mouse it does not unhighlight the other cells, in fact, its behavior becomes totally wierd. Any ideas? Mark Crispin / P.O.
