问题 After I add a subview to NSView, my mouse events respond to the area of NSView minus the addedSubVIew. How can I avoid that? I want it to respond on all of the superview. Thanks. 回答1: You can also implement the hitTest: method in the container view. - (NSView *) hitTest: (NSPoint) aPoint { return [super hitTest:aPoint] ? self : nil; } Now only the container view can receive the mouse events. 回答2: You can override the subviews [NSView hitTest:] method and return the superview. - (NSView *)

问题 I am using cocoa webview for rich text editing in my application. Just confused with innerHtml and outerHtml method avaiable in webkit. Can anyone explain what is the difference between [(DOMHTMLElement *)[[[webView mainFrame] DOMDocument] documentElement] outerHTML]; AND [(DOMHTMLElement *)[[[webView mainFrame] DOMDocument] documentElement] outerText]; 回答1: innerHTML is a property of a DOM element that represents the HTML inside the element, i.e. between the opening and closing tags. It has

问题 I'm trying to capture all the NSTextFinderClient calls on my custom NSTextView subclass. The show action is called on my -(void)performTextFinderAction:(id)sender override, but for find next, find previous, etc. it's not called. Any ideas? Thanks! Edit: If you create a new project and drag an NSTextView from interface builder, command-g and command-shift-g (find next and find previous) don't work when the find bar is first responder. Why is this? I need a custom subclass of NSTextView to

问题 I want to set a certain window, from an external app (for example textedit), to be front most. I can successfully get a reference to the app itself using GetFrontProcess, and check whether it is front most. If it is not, I can use setFrontProcess to make it focussed. I can then use the the accessibility API to examine all the windows under that application. I am checking that a certain window exists, and if so I compare it against the front most window of the application: //get the front

问题 I am wanting to change the text background color on a tableview's cell when it is hovered upon, similar to how AddressBook "highlights" the label of a contact's element when you mouseover the label names. However I cannot figure out how to accomplish... detecting a mouseover on a particular NSCell and... After detecting the cell his hovered upon, highlighting the text in that cell (not highlighting the entire row as if the user selected that row) As NSCell is not a subclass of NSView this
