| I have an nstableview with a modest number of rows and columns. Some of the cell contents can be quite long, so I need a tooltip to display the entire cell contents when the cursor hovers over it. Should be trivial right? I just implement this in my delegate:
- (NSString *)tableView:(NSTableView *)aTableView toolTipForCell:(NSCell *)aCell rect:(NSRectPointer)rect tableColumn:(NSTableColumn *)aTableColumn row:(int)row mouseLocation:(NSPoint)mouseLocation { return [aCell stringValue]; }
That mostly works. Unfortunately, the tooltips stop working when the user clicks too many times in the table. If the user clicks once in the tableview, nothing is affected and the toolTipForCell delegate method still gets invoked properly. If the user clicks twice or more (it usually takes at least four clicks) in the table, the method no longer gets called for any cell that the cursor then rests over. Functionality can be restored by moving the cursor out of the table rectangle and then back in over a cell, after which the tooltips start working again.
Is this normal behavior? If it is, it seems really inconsistent and confusing.
