如何创建从NSWindow模态弹出的NSPanel(可可编程) [英] How to create a NSPanel modally popuped from NSWindow (Cocoa programming)

问题描述

类似于在NSWindow中单击按钮后显示的NSPanel.

like NSPanel displayed after a button clicked in the NSWindow.

我找了很多东西，但没有简单的例子. 感谢您的帮助.

I looked for a lot but there is no simple example. Thanks for any help.

推荐答案

可以这样做:

-(IBAction)showButtonAction:(id)sender {
    [[NSApplication sharedApplication] beginSheet:panelOutlet
                                   modalForWindow:self.window
                                    modalDelegate:self
                                   didEndSelector:@selector(sheetDidEnd:returnCode:contextInfo:)
                                      contextInfo:nil];
}

注意:

不要忘记取消选中NSPanel的启动时可见复选框 属性检查器和关闭时发布，如果您不会一次使用此面板.

Don't forget to uncheck NSPanel's Visible At Launch checkbox in Attributes Inspector and Release When Closed if you will use this panel not once.
