NSPopover - 焦点丢失时隐藏？ （点击popover之外） [英] NSPopover - Hide when focus lost? (clicked outside of popover)

问题描述

我使用 NSTableView 的 doubleClickAction 显示 NSPopover 。这样的：

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];

我的popovers在我双击的单元格中创建和删除。问题是，如果我点击任何地方之外的任何地方（像单击另一个单元格），我想要popover消失。我一直在环顾四周，但对于我的生活，我无法弄清楚如何做。

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.

这是我认为是内置的popover，相当确定它是在iOS UIPopoverController 类），所以我只是想知道如果我缺少一些简单。

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.

推荐答案

我认为你需要改变你的popover的属性行为（在代码或界面构建器）到

I think you need to change the property behavior of your popover (in code or on interface builder) to

dataPreviewPopover.behavior = NSPopoverBehaviorTransient;

NSPopoverBehaviorTransient
The system will close the popover when the user interacts with a user interface element outside the popover.
