如何从NSOutlineView获取选定的单元格？ [英] How can I get the selected cell from a NSOutlineView?

问题描述

如何从NSOutlineView获取选定的单元格？
不是项目，而是单元格。
不是数据单元，而是当前单元本身。

How can I get the selected cell from a NSOutlineView? Not the item, but the cell. Not the datacell but the current cell itself.

这是基于单元的NSOutlineView。

It's a cell based NSOutlineView.

推荐答案

使用委托。 willDisplayCell：在单元格更改其选择状态时被调用。

Use the delegate. willDisplayCell: is called when a cell changes its selection state.

- (void)outlineView:(NSOutlineView *)outlineView willDisplayCell:(id)cell forTableColumn:(NSTableColumn *)tableColumn item:(id)item {
    id selectedItem = [outlineView itemAtRow:outlineView.selectedRow];
    if (item == selectedItem) {
        // 'cell' is selected cell for 'tableColumn'
    }
}
