NSButton 捕获鼠标点击事件
我有代码
#import <Cocoa/Cocoa.h>
@interface MyButton : NSButton
{
}
- (void)mouseDown:(NSEvent *)theEvent;
@end
#import "ContextMenuButton.h"
@implementation MyButton
- (void)mouseDown:(NSEvent *)theEvent;
{
// ...
}
根据 NSControl 类参考 mouseDown 通知接收者用户已按下鼠标左键。
我怎样才能捕获右键和其他鼠标按钮的点击？
I have the code
#import <Cocoa/Cocoa.h>
@interface MyButton : NSButton
{
}
- (void)mouseDown:(NSEvent *)theEvent;
@end
#import "ContextMenuButton.h"
@implementation MyButton
- (void)mouseDown:(NSEvent *)theEvent;
{
// ...
}
According to the NSControl Class Reference mouseDown informs the receiver that the user has pressed the left mouse button.
How could I catch right and others mouse button clicks?

NSControl间接派生自NSResponder，并且具有方法mouseDown:、rightMouseDown:和otherMouseDown ：，所有三个都以NSEvent*作为参数。NSControlderives, indirectly, fromNSResponder, and that has methodsmouseDown:,rightMouseDown:andotherMouseDown:, all three taking anNSEvent*as parameter.NSButton仅在左键单击时响应。无论如何，看看 NSEvent 类型。它确定了有关事件的大量信息，包括按下了哪个按钮。NSButtonresponds only on the left button click. Anyway take a look at NSEvent type. It determines a lot of info about event including wich button was pressed.
