NSWindowController 多个窗口之间传递值
主界面一个按钮点击,出现另一个窗口,然后输入123,点OK,在主界面的编辑框内可以得到123这个值,
思路:
由于要给主界面的控件赋值,所以在第二个窗口里面设定一个同类型的变量。
然后主界面的控件 = 第二个窗口的同类型变量。
例如:主界面是
NSTextField 控件1,
那么就在子窗口里面设定这样一个变量(NSTextField a1),给值。
然后在主界面调用时,让主界面的NSTextField 控件1 =a1
这样主界面就可以得到子界面的值了。
子界面代码如下
H文件
// // Form1.h // test_multi_window // // Created by EDU on 3/6/14. // Copyright (c) 2014 EDU.

@implementation Form1
@synthesize form_main;
@synthesize form_main_m_ET1;
@synthesize window_form1;
@synthesize button_ok_flag;
@synthesize button_string;

{

self = [super initWithWindow:window];
if (self)
{
}
return self;
}
- (void)windowDidLoad
{
[super windowDidLoad];
}
- (IBAction)OnBT_OK:(id)sender
{
form_main.stringValue = @"OK";
form_ok_cancel_result = true;
[self get_value];
[super close];
}
- (IBAction)OnBT_Cancel:(id)sender
{
form_main.stringValue = @"CANCEL";
form_ok_cancel_result = false;
[self get_value];
[super close];
}
-(void)get_value
{
form_main_m_ET1.stringValue = m_Edit1.stringValue;
}
@end主窗口代码如下
H文件
// // EDUAppDelegate.h // test_multi_window // // Created by on 3/6/14. // Copyright (c) 2014 EDU.

M文件

@synthesize m_form1;

- (void)dealloc
{
[super dealloc];
}
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
// Insert code here to initialize your application
}
- (IBAction)OnBT_Form1:(id)sender
{
if(!m_form1)
{
m_form1 = [[Form1 alloc] initWithWindowNibName:@"Form1"];
}
m_form1.window.title = @"Hello,this is a test";
m_form1.form_main = m_label1;
m_form1.form_main_m_ET1=m_ET1;
[m_form1 showWindow: sender];
}
@end
运行编译OK
如图:
完成!
