问题 What is the maximum iframe width of a facebook page? 回答1: It was 520px. As with a Canvas Page, the amount of space available to your app is bounded by the outer context of Facebook. Since your app is also loaded inside of Facebook Page, the space is smaller (520 pixels) than what is available to on a Canvas Page. from FB docs (yes i know that doc about canvas and it's only mentions iframes, but i cannot find quickly reference to full iframe documentation) Important Update On the March 30th

Possible to prevent our website from running inside another domain's frameset or IFrame?

阅读更多关于 Possible to prevent our website from running inside another domain's frameset or IFrame?

问题 We've been having an problem recently where other sites are running our e-commerce site inside a frameset where our site (with the offenders affiliate id tacked on) is the only content in a single full width frame. So essentially it looks and feels like our site with their URL at the top. We can cut off their affiliate id, which would make it pointless for them to do, but this doesn't prevent future offenders from doing the same thing until we find out about it. Is there a generic way

ttk: how to make a frame look like a labelframe?

阅读更多关于 ttk: how to make a frame look like a labelframe?

Python ttk gui creating is easy and has mostly native look and feel (win7). I am having a slight problem, though: I would like to have a frame that looks like ttk.LabelFrame but without label. Just omitting the text option will leave an ugly gap. Also I can not get the ttk.Frame border to look like LabelFrame. Is there an elegant way of doing this? Bonus karma if this works on all/most windows versions above xp. Maybe it works with styles but the style LabelFrame properties seem mostly empty (style.element_options("border.relief")). Maybe I am looking in the wrong place. edit: try: # python 3

Why can't I change the view's frame size in Swift?

阅读更多关于 Why can't I change the view's frame size in Swift?

So this is the weirdest thing I came across ever. I add a simple UIView on top of an UIView on an UIViewController . I change the size to 200 x 200 and then I want to change the UIView 's size by placing this line of code inside the viewDidLoad method: self.gameBackgroundView.frame.size.height = 10 which seems perfectly normal in Swift. Though, nothing happens. I can change the color, corner radius etc... EDIT: I have also deleted all constraints from that view and it still does not work. kalafun Ok, So I found a solution here on stack .. Change frame programmatically with auto layout The

Center a UIView vertically and horizontally within its parent view

阅读更多关于 Center a UIView vertically and horizontally within its parent view

I have a UICollection view that is inside another UIView. I am trying to center the collection view inside its parent view. Currently manually doing it by tweaking its frame (see code below). There has to be a easier way. CURRENT CODE: self.collectionView = [[UICollectionView alloc] initWithFrame:CGRectMake(COLLECTION_PADDING+10, COLLECTION_PADDING+5, self.bounds.size.width - (COLLECTION_PADDING*2), self.bounds.size.height - (COLLECTION_PADDING+22)) collectionViewLayout:flow]; Logan You could do something like this: self.collectionView.center = CGPointMake(CGRectGetMidX(superview.bounds),

What are the 0 bytes at the end of an Ethernet frame in Wireshark?

阅读更多关于 What are the 0 bytes at the end of an Ethernet frame in Wireshark?

after ARP protocol in a frame, there are many 0 bytes. Does anyone know the reason for the existence of these 0 bytes? Check the Ethernet II accordion, all the 0 are labelled as padding. Ethernet requires that all packets be at least 60 bytes long (64 bytes if you include the Frame Check Sequence at the end), so if a packet is less than 60 bytes long (including the 14-byte Ethernet header), additional padding bytes have to be added to the end of the packet. (Those padding bytes will not show up on packets sent by the machine running Wireshark; the padding is added by the Ethernet hardware, and

How to get frame size after autoresize is done

阅读更多关于 How to get frame size after autoresize is done

I wonder, how and when (viewDidLoad, viewWillAppear, viewDidAppear) can I get a UIViews frame size that was autoresized to fit its partent view? Rog It's not clear from your question why you want it but I imagine it is to layout your sub views. Luckily Apple knew you would want to do that and implemented -(void)layoutSubViews see this: When is layoutSubviews called? I tried layoutSubviews , but it gets called more than once which is a problem when I need the auto sized frame in order to create a CGContext to draw into. The solution I used was to expose an init method on my custom UIView for
