NSMenu的习俗 NSPopUpButton甄选项目
原标题:Custom view in NSMenuItem disables the NSPopUpButton selection

我想定制一个<条码>NSPopUpButton,因此我实施了<条码>。 海关数据,目前只有以下代码(用于测试目的):

- (void)drawRect:(NSRect)dirtyRect
{
    [[NSColor redColor] set];
    NSRectFill(dirtyRect);
}

现在每条<代码>NSMenuItem i 加入NSMenu,myPopUpButton.menu 我持我的习惯观点:

NSMenuItem *menuItem = [[NSMenuItem alloc] initWithTitle:@"Some title" action:NULL keyEquivalent:@""];
menuItem.view = [[CustomMenuItemView alloc] initWithFrame:NSMakeRect(0, 0, 100, 25)];

当我管理我的节目并开放播音台时,菜单选择似乎是残疾的(即我点击时没有发生)。

我猜测,这并非实际上的残疾;它只是对事件的反应。 在我的习俗中,我是否需要增加一些活动? 如果是,如何?

最佳回答

我通过添加<代码>mouseUp来解决这个问题。 我的<密码>方法:

- (void)mouseUp:(NSEvent*) event
{
    NSMenu *menu = self.enclosingMenuItem.menu;
    [menu cancelTracking];
    [menu performActionForItemAtIndex:[menu indexOfItem:self.enclosingMenuItem]];
}
