bounds

问题 I have a text field inside a container. I'm wondering is it possible to find the boundaries of each character based on the container and not the text field. Here is a sample screen shot: And normal state would be like this: With this I can find the bounds of each character based on text field, But I need it based on the container: var rect:Rectangle = new Rectangle(); for (var i:int = 0; i < textField.length; i++){ rect = textField.getCharBoundaries(i); } Is there anybody whom has an

问题 I know there are lots of similar questions here and I checked the famous one, and then grasped the difference between Bounds, and Frame. Now I have some problem related to them. I played around with them , but it didn't show as I expected. What I don't understand here is: Why the frame origin of Y is 44.000000 below the top even I set the UIImageView at the left corner? Because bounds should be "The bounds of an UIView is the rectangle, expressed as a location (x,y) and size (width,height)

问题 For the life of me, I can't seem to get help on this. I have a JavaFX screen and I am trying to get to show fullscreen on my 2nd monitor. I tried the following based on other recommendations but to no avail. I know the coordinates are right but it KEEPS going full screen on my MAIN monitor. Please help. if (mainSet.getBoolean("fullScr", false)) { int count = mainSet.getInt("MonSel", 0); if (count > 0) { int i = 0; for (Screen screen: Screen.getScreens()) { if (count == i) { Rectangle2D bounds

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 Writing my first non-trivial MiniZinc app, I keep running into the error "cannot determine bounds". How does one generally resolve this error? 回答1: In general “cannot determine bounds” means that the solver cannot determine the bounds (the domain) of a decision variable. Using "var int" as the domain of a decision variable should be avoided if possible, since it will probably slow down the solving process. There are times where the solver can figure out the domain, e.g. in cases likes % ...

问题 I have a full screen UIScrollView to display my image, which employ some codes from PhotoScroller.app from apple sample code. I am little confused on the bounds of a imageView in a scrollView with rotation, and the convertPoint. Any help will be appreciated! ps. For more detail codes please find in Center of bounds NSLog in call willRotateToInterfaceOrientation:duration: 2012-05-12 11:35:45.666 imageScrollView frame X and Y are 0.000000 and 0.000000 2012-05-12 11:35:45.672 imageScrollView

问题 I want to achieve the effect shown in the images attached. Given certain items, fit them into a shape (box or something else), with the option to resize the items or not. I know there has to be some algorithm related, but I don't know where to start looking. Any keyword , wikipedia article, or pdf will be welcome. 回答1: The problem, as NKamrath pointed out, was Bin packing problem , but more commonly refered to Texture Packing . Here are the resources I gathered: http://en.wikipedia.org/wiki

问题 Why can the Price not find the attribute value on the SeqValue? It seems so simple that is should work. Im getting the error [error] .... value value is not a member of type parameter SeqValue [error] def recalc[SeqValue](input:SeqValue) = Price(1 + seq, input.value) for the following code sealed trait SeqValue { def seq:Int def value:Float override def toString = ToStringBuilder.reflectionToString(this, ToStringStyle.SHORT_PREFIX_STYLE) } sealed trait Calc { type S <: SeqValue def recalc[S]

问题 I have a few markers that I retrieve and want to center the map to. Yes, I have read all the other answers, but it doesn't seem to work for me: Google Map API v3 — set bounds and center JS: geocoder.geocode( {'address': loc}, function(results, status) { if (status == google.maps.GeocoderStatus.OK) { var markerBounds = new google.maps.LatLngBounds(); var coordinate = results[0].geometry.location; var icon = new google.maps.MarkerImage("images/icon-"+type+".png", new google.maps.Size(37, 44));
