frame

问题 How do I change the URL of the browser with a website using a structure of <frame> . I know the whole point of <frame> is to use embedded frames so that you can't tell where the site is going. In particular, when you click a link, the frame changes, but the URL at the top of the browser says the same thing. I'm trying to make it so that the browser CHANGES the URL, so the real URL of the main inner frame is shown at all times. How can I do this? 回答1: You can't; best bet is to change the

问题 I'm trying to use the new ASC2.0 compiler in the AIR SDK 3.7, but I seem to be running into a problem where it cannot detect my preloader class. If I use the non-ASC2.0 compiler, it recognizes and compiles the Preloader class declared in the Frame metadata tag in my Main class, like so: [Frame(factoryClass = "Preloader")] But as soon as I compile it with ASC2.0, it disregards the Frame metadata and just tries to compile the Main class and assume that it HAS to be a subclass of Sprite /

问题 I am trying to set the origin of the frame programmatically. Method1: button.frame.origin.y = 100; Method 2: CGRect frame = button.frame; frame.origin.y = 100; I tried method 1 but it is not working(showing an error saying Expression is not assignable). Method 2 is working. Why is this so? Need guidance on what I am doing right. 回答1: The reason you can't do method #1 is because a frame's individual properties are read-only. However, the entire frame itself is writable/assignable, thus you can

问题 Apropos of This question, there is a bit of scaffolding within the interpreter to inspect frame objects, which can be retrieved by sys._getframe() . The frame objects appear to be read only, but I can't find anything obvious in the docs that explicitly states this. Can someone confirm whether these objects are writeable (in some way) or read only? import sys def foobar(): xx='foo' ff = sys._getframe() ff.f_locals['xx'] = 'bar' print xx if __name__ == '__main__': foobar() This prints out ' foo

问题 I happened to something strange to me on CALayer.And finally found the CALayer's frame.size not equal to its bounds.size, which I couldn't understand.I know frame is in the super's coordinate system and bounds is its own coordinate,and the usual case is frame.origin is not equal to bounds.origin but frame.size is equal to bounds.size. 回答1: That is because you applied a transform, as apple says on the documentation for the frame property. Warning If the transform property is not the identity

问题 I'm creating a single page application with Golang on the backend and javascript on the frontend. I´d like to find a way how to get the first frame of a video using Golang. First, I upload a .mp4 video file to the server. It is saved on the server. Is there a way to get the first frame of this video, using Golang? It should be possible to do it using Javascript on frontend, but I don't feel like it is the right way to solve this issue. I have no idea how to implement it using Golang, and I

问题 I built a pdf using reportlab, to have more controle one the page (colors- padding- return to line...) I created a frame. the issue is that, my text is coming from a database and it need more than one page. I want to know how to tell that its the end of the page/frame and I should create a new one for the rest of text. import MySQLdb import pprint import sys import csv from datetime import * from reportlab.pdfgen import canvas from reportlab.lib.styles import getSampleStyleSheet from

问题 I'm creating label and characters, I want set frame (X, Y and width) of UILabel by characters and Y-axis is constant of all devices, so how can I set center of X-axis and controlling by count of characters, and width (50) gets smaller and bigger per device ?? This my code : func createTarget(id: Int) { listdata = dbHelpr.getDatabase(rowId: id) for data in listdata { let lengthOfChar : CGFloat = data.ans.length let targetSize : CGFloat = self.view.frame.width / 2 var xAxis : CGFloat = self

问题 EDIT 5: Optimization level build settings: EDIT 4: I tried to change the build configuration putting all to "Debug" and then run for "testing". Weirdly enough it didn't crash for about 20 times (I kept load and unloading various GameScenes whith different assets). At the 21st time (even if not statistically relevant) I was about to think that it might not crash anymore but it crashed. The summary is still unavailable so I am wondering if I am doing it right or if there is some other issue..

问题 when I use: ImageView.transform = CGAffineTransformRotate(ImageView.transform, rotation); everytime I rotate imageView and I NSLog(@"x:%f y:%f", ImageView.frame.orgin.x, ImageView.frame.orgin.y), x and y always change value?? Why? 回答1: Well the .frame.origin is the top left corner of you UIImageView and since you are rotating it the top left corner is moving. If you access the .center it should stay the same. 回答2: The UIView documentation states that Warning: If this property is not the
