You cannot really use the view conversion API between views in
different windows, and even if you could, you still wind up with
window-based coords, not screen. I would try something more like:
- (void)textDidChange {
if ([myTableView editedColumn]==6) {
NSPoint origin =[myTableView frameOfCellAtColumn:6
row:[myTableView selectedRow]].origin;
// Convert to window coords
origin = [myTableView convertPoint:origin toView:nil];
// Convert to screen coords
origin = [[myTableView window] convertBaseToScreen:origin];
[notesWindow setFrameOrigin:origin];
[myParentWindow addChildWindow:notesWindow
ordered:NSWindowAbove];
[notesWindow makeFirstResponder:nil];
}
}

Subject: NSTableView: cell frame coordinates
Ok, I want to make it so that each time a cell in a certain column of a
table column is edited, a little window with an NSTextView in it pops
up just below the edited cell.
Here is what I have done so far. I have subclassed NSWindow to make a
window borderless and without a top bar. I also have it so that when
the right cell is edited my custom window appears, but it appears in
the wrong spot. I am still learning about coordinates, so hopefully
someone can tell me what is wrong with this code. This is what gets
called, when the text begins editing:
- (void)textDidChange {
if ([myTableView editedColumn]==6) {
NSRect aRect =[myTableView frameOfCellAtColumn:6 row:[myTableView
selectedRow]];
aRect = [myTableView convertRect:aRect toView:notesView]; //notesView
is my NSTextView in my custom window
NSPoint origin = NSMakePoint(aRect.origin.x, aRect.origin.y);
[notesWindow display]; //this is my custom window with NSTextView
in it
[notesWindow setFrameOrigin:origin];
[myParentWindow addChildWindow:notesWindow ordered:NSWindowAbove];
[notesWindow makeFirstResponder:nil];
}
}
Can someone please lend a hand to a newbie trying to do things he
doesn't know how to do?
Thanks,
Ian
