问题描述
我想在 NSWebView
之上有一些UI控件,因为这个问题我现在要添加一个透明 NSWindow
,所以没有关闭按钮等,在 NSWebView
的顶部,因此,在当前 NSWindow
。
I want to have some UI controls on top of a NSWebView
and because of this problem " Video in NSWebView hides views on top of the NSWebView " I now want to add a "transparent" NSWindow
, so without the close buttons etc., on top of my NSWebView
, hence, on top of my current NSWindow
.
如何实现这一点,并确保这个覆盖窗口保持原位,即使我移动底层窗口?
How can I achieve this and make sure that this "overlay window" stays in place, even if I move the underlying window?
编辑:@ dzolanta的方法工作正常,我想知道是否可以通过使用 NSWindowController
这将允许我正确使用Outlets等。
: While @dzolanta's approach works fine, I wonder if it is possible to do it by using an NSWindowController
which would allow me to properly use Outlets etc.
推荐答案
子窗口是你需要的
使用 NSBorderlessWindowMask
创建 NSWindow
透明使用 - setOpaque:
和 - setBackgroundColor:
方法。然后将新创建的窗口添加为包含 NSWebView
(使用 NSWindow
的 - addChildWindow:ordered:
方法)。移动父窗口会自动导致子窗口移动。
Create NSWindow
with NSBorderlessWindowMask
and define it to be transparent using - setOpaque:
and - setBackgroundColor:
methods. Then add newly created window as a child of window containing an instance of NSWebView
(using NSWindow
's - addChildWindow:ordered:
method). Moving parent window will automatically cause child window to move.
使用工作代码更新:
CGRect wRect = self.window.frame;
NSView *contentView =self.window.contentView;
CGRect cRect = contentView.frame;
CGRect rect = CGRectMake(wRect.origin.x, wRect.origin.y, cRect.size.width, cRect.size.height);
NSWindow *overlayWindow = [[NSWindow alloc]initWithContentRect:rect
styleMask:NSBorderlessWindowMask
backing:NSBackingStoreBuffered
defer:NO];
overlayWindow.backgroundColor = [NSColor redColor];
[overlayWindow setOpaque:NO];
overlayWindow.alphaValue = 0.5f;
[self.window addChildWindow:overlayWindow ordered:NSWindowAbove];
