如何显示从xib加载的表？ （MacOSx） [英] How show sheet loaded from xib? (MacOSx)

问题描述

我有一个xib文件，只有一个NSPanel在其中，我试图显示这个面板作为模式表（与 beginSheet：modalForWindow：modalDelegate：didEndSelector：contextInfo：）。这个xib文件的所有者是一个控制器类MyController，它有NSPanel的IBOutlet。

I have a xib file with only an NSPanel in it, I'm trying to show this panel as modal sheet (with beginSheet:modalForWindow:modalDelegate:didEndSelector:contextInfo:). The file's owner for this xib is a controller class "MyController" which has the IBOutlet to the NSPanel.

我正在寻找的是：

...
MyController *controller = [[MyController alloc] init];

[NSApp beginSheet:controller.panel modalForWindow:[NSApp mainWindow] modalDelegate:controller didEndSelector:nil contextInfo:nil];
...

问题：
必须MyController继承自 NSWindowController 或 NSObject ?.我尝试了 NSWindowController 和 initWithWindowNibName：但出口到 NSPanel

Question: Must MyController inherit from NSWindowController or NSObject?. I tried NSWindowController and initWithWindowNibName: but the outlet to NSPanel always is nil.

感谢

推荐答案

您必须停用您用于工作表的窗口对象（在IB中）的几乎所有属性。我添加以下方法到我的控制器以显示工作表：

I resolve it. You must deactivate almost all the properties of the window object (in the IB) that you are using for the sheet. I add the following method to my controller to show the sheet:

- (void)showInWindow:(NSWindow *)mainWindow {
    if (!panelSheet)
        [NSBundle loadNibNamed:@"XibName" owner:self];

    [NSApp beginSheet:panelSheet modalForWindow:mainWindow modalDelegate:nil didEndSelector:nil contextInfo:nil];
    [NSApp runModalForWindow:panelSheet];   //This call blocks the execution until [NSApp stopModal] is called
    [NSApp endSheet:panelSheet];
    [panelSheet orderOut:self];
}

panelSheet IBOutlet到工作表窗口。

panelSheet is an IBOutlet to the sheet window.
