[SOLVED] NSPopover - Hide when focus lost? (clicked outside of popover)

NSPopover - Hide when focus lost? (clicked outside of popover)

I'm using the doubleClickAction of a NSTableView to display a NSPopover. Something like this:

NSInteger selectedRow = [dataTableView clickedRow];
NSInteger selectedColumn = [dataTableView clickedColumn];


// If something was not selected, then we cannot display anything.
if(selectedRow < 0 || selectedColumn < 0)
{
    NSLog(@"Invalid selected (%ld,%ld)", selectedRow, selectedColumn);
    return;
} // End of something was not selected

// Setup our view controller, make sure if there was already a popover displayed, that we kill that one off first. Finally create and display our new popover.
DataInspectorViewController * controller =
[[DataInspectorViewController alloc] initWithNibName: @"DataInspectorViewController"
                                              bundle: nil];

if(nil != dataPreviewPopover)
{
    [dataPreviewPopover close];
} // End of popover was already visible

dataPreviewPopover = [[NSPopover alloc] init];
[dataPreviewPopover setContentSize:NSMakeSize(400.0f, 400.0f)];
[dataPreviewPopover setContentViewController:controller];
[dataPreviewPopover setAnimates:YES];
[dataPreviewPopover showRelativeToRect: [dataTableView frameOfCellAtColumn: selectedColumn row: selectedRow]
                     ofView: dataTableView
              preferredEdge: NSMinYEdge];

Which works just fine. My popovers get created and removed on the cells that I double click on . The problem is, I want to the popover to go away if I click anywhere outside of it (like a single click on another cell). I have been looking around, but for the life of me cannot figure out how to do it.

This is something I would assume is built into a popover, (I'm fairly certain it was in the iOS UIPopoverController class) so I'm just wondering if im missing something simple.

Solution

You need to change the property behavior of your popover (in code or on interface builder) to:

popover.behavior = NSPopover.Behavior.transient;

NSPopover.Behavior.transient
The system will close the popover when the user interacts with a user interface element outside the popover.
