我可以使用窗口内的对象来移动窗口吗？

发布于 2024-08-15 21:04:42 字数 125 浏览 8 评论 0原文

在 Cocoa 中是否可以通过拖动窗口内的对象来移动窗口？例如：我在窗口内有一个 webview，与窗口一样大，所以 setMovableByWindowBackground 显然不起作用。有没有办法单击并拖动网络视图并移动整个窗口？

当然，您只需使用 mouseDragged 来跟踪鼠标移动即可。与此类似的东西应该有效：

- (void)mouseDragged:(NSEvent *)theEvent
{
   NSPoint currentLocation;
   NSPoint newOrigin;

   NSRect  screenFrame = [[NSScreen mainScreen] frame];
   NSRect  windowFrame = [self frame];

    currentLocation = [NSEvent mouseLocation];
    newOrigin.x = currentLocation.x - initialLocation.x;
    newOrigin.y = currentLocation.y - initialLocation.y;

    // Don't let window get dragged up under the menu bar
    if( (newOrigin.y+windowFrame.size.height) > (screenFrame.origin.y+screenFrame.size.height) ){
        newOrigin.y=screenFrame.origin.y + (screenFrame.size.height-windowFrame.size.height);
    }

    //go ahead and move the window to the new location
    [self setFrameOrigin:newOrigin];
}

Sure, you've just got to track the mouse movements using mouseDragged. Something similar to this should work:

- (void)mouseDragged:(NSEvent *)theEvent
{
   NSPoint currentLocation;
   NSPoint newOrigin;

   NSRect  screenFrame = [[NSScreen mainScreen] frame];
   NSRect  windowFrame = [self frame];

    currentLocation = [NSEvent mouseLocation];
    newOrigin.x = currentLocation.x - initialLocation.x;
    newOrigin.y = currentLocation.y - initialLocation.y;

    // Don't let window get dragged up under the menu bar
    if( (newOrigin.y+windowFrame.size.height) > (screenFrame.origin.y+screenFrame.size.height) ){
        newOrigin.y=screenFrame.origin.y + (screenFrame.size.height-windowFrame.size.height);
    }

    //go ahead and move the window to the new location
    [self setFrameOrigin:newOrigin];
}
