如何从我的全局热键中粘贴其他应用程序 [英] How to get other application to paste from my global hotkey

问题描述

我写了一个小型的生产力工具，可以通过剪贴板进行一些字符串操作.

I have written a small productivity tool that does a few string manipulations via the clipboard.

当前正在注册一个热键，它会在其中拉出剪贴板中的文本，对其进行处理，然后将结果转储到剪贴板中.

It is currently registering a hot key, where it pulls in the clipboard text, processes it, and dumps the result back on the clipboard.

我已在CMD + SHIFT + V上安装了此

I have this installed on CMD+SHIFT+V

当前，您需要从另一个应用程序执行的操作是复制(CMD + C)，然后激活我的热控器(CMD + SHIFT + V)，然后必须使用(CMD + V)将其粘贴回原始应用程序中

currently what you need to do from another apppiclation is copy (CMD+C) and then activate my hothandler (CMD+SHIFT+V), and then you have to paste it back into the orginal app with (CMD+V).

如果可能的话，我想省去第三步，所以我的处理程序会以某种方式告知要粘贴的活动应用程序.

I'd like to eliminate the third step if possible, so my hothandler somehow tells whatever is the active application to paste.

任何建议如何做到这一点?

Any suggestions how to do this?

我的代码(减去无聊的文字替换的实际内容)是这样的:

My code (minus the actual boring text replacement stuff) is this:

请注意，热键处理程序需要碳框架

我从堆栈溢出时的此答案借来了热键处理程序代码.

I borrowed code from this answer on stack overflow for the hotkey handler code.

AppDelegate.h

#import <Cocoa/Cocoa.h>
#import <Foundation/Foundation.h>
#import <Carbon/Carbon.h>

@interface AppDelegate : NSObject <NSApplicationDelegate>  {

    EventHotKeyRef  hotKeyRef;
}

@property (assign) IBOutlet NSWindow *window;
-(IBAction) checkClipboard:(id) sender ;

@end

AppDelegate.m

#import "AppDelegate.h"
//#import "NSString+cppMacros.h" // not relevant to question




OSStatus _AppDelegateHotKeyHandler(EventHandlerCallRef nextHandler, EventRef event, void *userData) {
    AppDelegate *appDel = [[NSApplication sharedApplication] delegate];
    [appDel checkClipboard:nil];
    return noErr;
}

@implementation AppDelegate



- (void)installHotkey {

    if (!hotKeyRef) {
        EventHotKeyID   hotKeyId;
        EventTypeSpec   eventType;

        eventType.eventClass    = kEventClassKeyboard;
        eventType.eventKind     = kEventHotKeyPressed;

        InstallApplicationEventHandler(&_AppDelegateHotKeyHandler, 1, &eventType, NULL, NULL);

        hotKeyId.signature  = 'hotk';
        hotKeyId.id         = 1337;

        RegisterEventHotKey(kVK_ANSI_V, cmdKey + shiftKey, hotKeyId, GetApplicationEventTarget(), 0, &hotKeyRef);
        NSLog(@"_AppDelegateHotKeyHandler installed");

    }
}

-(void) uninstallHotkey {
    if (hotKeyRef) {
        UnregisterEventHotKey(hotKeyRef);
        hotKeyRef = nil;
        NSLog(@"_AppDelegateHotKeyHandler uninstalled");
    }

}



-(IBAction) checkClipboard:(id) sender {

    NSPasteboard *pasteboard = [NSPasteboard generalPasteboard];


    NSArray *types = [NSArray arrayWithObjects:NSStringPboardType, nil];



    NSString *text = [pasteboard  stringForType:NSPasteboardTypeString];

    NSLog(@"clipboard input:%@",text);

    /* actual code is this: (not relevant to question)
     NSString *newText = [text isMacroEncoded] ? [text macroDecodedString] : [text macroEncodedString];
     */
    // demo code for question

    NSString *newText = [@"Pasted:" stringByAppendingString:text];


    [pasteboard declareTypes:types owner:self];

    [pasteboard setString:newText forType:NSStringPboardType];

    NSLog(@"clipboard output:%@",newText);

}


- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
    // Insert code here to initialize your application
    hotKeyRef = nil;
    [self installHotkey];
}

-(void) applicationWillTerminate:(NSNotification *)notification {
    [self uninstallHotkey];
}



@end

推荐答案

事实证明，有一种方法可以满足我的要求.

It turns out there is a way to do what I want.

void pasteCurrent() {

    CGEventRef commandDown = CGEventCreateKeyboardEvent(NULL, kVK_Command, YES);
    CGEventRef VDown = CGEventCreateKeyboardEvent(NULL, kVK_ANSI_V, YES);

    CGEventRef VUp = CGEventCreateKeyboardEvent(NULL, kVK_ANSI_V, NO);
    CGEventRef commandUp = CGEventCreateKeyboardEvent(NULL, kVK_Command, NO);

    CGEventSetFlags(VDown,kCGEventFlagMaskCommand);
    CGEventSetFlags(VUp,kCGEventFlagMaskCommand);

    CGEventPost(kCGHIDEventTap, commandDown);
    CGEventPost(kCGHIDEventTap, VDown);
    CGEventPost(kCGHIDEventTap, VUp);
    CGEventPost(kCGHIDEventTap, commandUp);

    CFRelease(commandDown);
    CFRelease(VDown);
    CFRelease(VUp);
    CFRelease(commandUp);

}
