Re: NSTableview tooltip bug?

Thanks! Got it running in a few minutes. For others, I used the NSTableViewDelegate methods tableView:toolTipForCell:rect:tableColumn:row:mouseLocation: and tableView:shouldShowCellExpansionForTableColumn:row: to prevent the cell expansion. Don Hall Apps & More Software Design, In

Re: NSTableView doesn't show data until I click on a header

Got it, it all works (I think :). The only thing that made me scratch my head was how to empty the whole array. Right now I am using this, but any suggestions or improvements are welcome: NSRange range = NSMakeRange(0, [self countOfMyObjects]); NSIndexSet *indexes = [NSIndexSet indexSetWithIndex

Are there any way to update NSPanel content during dragging the panel ?

My custom NSView in a NSPanel shows some information depends on panel's position to the main window. I want to update it during dragging the panel. I try [self setNeedsDisplay:YES] in mouseDragged: delegate, drawRect: called many times during dragging, but it will not appear on screen until mo

Re: Instruments, how to fix leak in C Lib

Look at Valgrind - it works on the Mac now. What you do is have a demo app or even a GUI that launches, runs, then quits. You enter your app and args as arguments to valgrind when you run it. Valgrind monitors every malloc, and when the app/program quits tells you not only what leaks you have,

Re: NSTableview tooltip bug?

hi don, I recommend using the builtin tooltip support in NSTableView. There is a delegate method to provide the tool tip. Next, you are seeing expansionToolTips. Look at NSCell.h for custom drawing API for them. Or, turn them off for your table with API on NSTableView. corbin On May 1, 2012, a

Thank you all for the replies! As I said above, I don't want the question to be whether I should better use NIBs, or whether Cocoa is more suitable than assembler. I somewhat know already what the role of NIB is, that it can save time and so on. What I would like to know is what to do if I was not
