我使用 NSIMage View 在 NS Window 上显示图像。 图像将位于用户通常可以拖动窗口的区域的顶端 。
窗口的样式不易看出您可以拖动窗口... 因此我需要这个小图像来显示您“ em> can em” 实际上拖动窗口 。
不幸的是, 我无法找到如何点击拖动窗口的图像! 它需要这个 。 在窗口标题区域的其他任何地方拖曳工作正常 。
我怎样才能点击并按住图像拖动整个窗口?
如果您能告诉我如何在悬浮于此图像时给鼠标一个“ 拖动图标” 光标, 则会得到好处 。

我认为最简单的方式是让NSIMage View(NSIMage View)下级, 并返回到鼠标Down CanMoveWindow(它继承了NSView)。
-(BOOL)mouseDownCanMoveWindow {
return YES;
}
当鼠标进入图像视图时, 您可以在 NSImageView 子类中压倒重设 Cursor Rects, 从而设定新的光标( 我不知道您在“ 拖动图标” 光标中指什么, 因此此示例使用指针光标 :
- (void)resetCursorRects {
[self addCursorRect:self.bounds cursor:[NSCursor pointingHandCursor]];
}
NSimageView
有自己的鼠标处理程序。 要改变视图的行为方式, 您必须使用子类, 要么是 NSView
, 要么是 NSimageView
。
