In general, holding the Command key down while clicking user controls in a
background application appears to be the standard Mac OS X convention for
keeping the application in the background. But it doesn't work in table
views without a little help.
In PreFab UI Browser 2.0, I allow a Command-click on a table view row to
select the row while leaving the application in the background by
subclassing NSTableView and overriding -mouseDown:, as shown below. The call
to the -tableView:shouldSelectRow: delegate method is in there because I
implement it anyway for other reasons; if you don't need that, you'll have
to modify this snippet a little.
@implementation PFClickthroughTableView
- (void)mouseDown:(NSEvent *)event {
// Allow Command-click on a table row to select the row under the mouse
if the application is in the background, without bringing the application to
the front; normally, Command-click would deselect the row.
if (![NSApp isActive] && ([event modifierFlags] & NSCommandKeyMask)) {
NSInteger row = [self rowAtPoint:[self convertPoint:[event
locationInWindow] fromView:nil]];
if ([[self delegate] tableView:self shouldSelectRow:row]) {
[self selectRowIndexes:[NSIndexSet indexSetWithIndex:row]
byExtendingSelection:NO];
[self sendAction:[self action] to:[self target]];
}
return;
}
[super mouseDown:event];
}
