自定义工作表：无法单击按钮 [英] Custom Sheet : can't click buttons

问题描述

我使用此来源 http：//www.cats.rwth-aachen。 de / library / programming / cocoa

创建我的自定义工作表。

to create my custom sheet.

NSPanel 现有.xib文件中的对象，并与 IBOutlet

I created a NSPanel object in existing .xib file and connected with IBOutlet

我的源代码：

.h

@interface MainDreamer : NSWindow <NSWindowDelegate> 
{    
 ...
 NSPanel *newPanel;
}
...
@property (assign) IBOutlet NSPanel *newPanel;

.m

@dynamic newPanel;
...

//this method is wired with button on main window and calls a sheet
- (IBAction)callPanel:(id)sender
{
    [NSApp beginSheet:newPanel
       modalForWindow:[self window] modalDelegate:self
       didEndSelector:@selector(myPanelDidEnd:returnCode:contextInfo:)
          contextInfo: nil]; //(__bridge void *)[NSNumber numberWithFloat: 0]
}

//this method is wired with cancel and ok buttons on the panel
- (IBAction)endWorkPanel:(id)sender
{
    [newPanel orderOut:self];
    [NSApp endSheet:newPanel returnCode:([sender tag] == 9) ? NSOKButton : NSCancelButton];
} 

//closing a sheet
- (void)myPanelDidEnd:(NSWindow *)sheet returnCode:(int)returnCode contextInfo:(void *)contextInfo
{
    if (returnCode == NSCancelButton) return;
    else{
        return;
    }
}

所以 callPanel 工作正常，工作表出现，但我不能与工作表上的控件交互（使用按钮）。

So callPanel works fine, sheet appears but I can't interact with controls on the sheet (with buttons). They don't react on a click (even visually).

问题出在哪里？

推荐答案

他忘记了

[newDreamPanel close];

我写了它，因为我希望主窗口启动时不出现面板。

in applicationDidFinishLaunching method. I wrote it because I wanted the panel to not appear when main window launches.

事实上，可见启动面板的属性应在IB中激活。 close 方法也起作用，但副作用是所有控件在面板上无法显示。

In fact, the Visible At Launch panel's property should be activated in IB. The close method works too, but side effect is that all controls become unable on the panel.
