  • format - Help with printing a table

    - by Michael Kohl
    This question will probably end in a facepalm, but I've tried for a while and am still stuck despite reading through the hyperspec. Basically what I want to do is something like (format t "~{|~{ ~5d~}|~%~}" '((1 23 2 312) (23 456 1 7890))) but instead of hard-coding the 5 it should be calculated from the list (length of longest element from any nested list + 1) to give something like | 1 23 2 312| | 23 456 1 7890| Maybe I'm thinking way too complicated here and there is an easier way to do what I want, but I think I ran myself into a mental corner that I can't get out of.

  • synchronized in java - Proper use

    - by ZoharYosef
    I'm building a simple program to use in multi processes (Threads). My question is more to understand - when I have to use a reserved word synchronized? Do I need to use this word in any method that affects the bone variables? I know I can put it on any method that is not static, but I want to understand more. thank you! here is the code: public class Container { // *** data members *** public static final int INIT_SIZE=10; // the first (init) size of the set. public static final int RESCALE=10; // the re-scale factor of this set. private int _sp=0; public Object[] _data; /************ Constructors ************/ public Container(){ _sp=0; _data = new Object[INIT_SIZE]; } public Container(Container other) { // copy constructor this(); for(int i=0;i<other.size();i++) this.add(other.at(i)); } /** return true is this collection is empty, else return false. */ public synchronized boolean isEmpty() {return _sp==0;} /** add an Object to this set */ public synchronized void add (Object p){ if (_sp==_data.length) rescale(RESCALE); _data[_sp] = p; // shellow copy semantic. _sp++; } /** returns the actual amount of Objects contained in this collection */ public synchronized int size() {return _sp;} /** returns true if this container contains an element which is equals to ob */ public synchronized boolean isMember(Object ob) { return get(ob)!=-1; } /** return the index of the first object which equals ob, if none returns -1 */ public synchronized int get(Object ob) { int ans=-1; for(int i=0;i<size();i=i+1) if(at(i).equals(ob)) return i; return ans; } /** returns the element located at the ind place in this container (null if out of range) */ public synchronized Object at(int p){ if (p>=0 && p<size()) return _data[p]; else return null; }

    - by Boris Senderovich
    Example: There is a matrix of data called VE There is a vector of string where the first element is the string VE. I need to indirectly call the string and be able to access data.

  • How to set clickable and highlightable a View?

    - by Pentium10
    I have ViewStubs in my layout. If I set clickable and implement the OnClickListener this does work only on the root of the element. But the layout holds parent elements, and when I click on those the click is not recognized. How do I make a full row/view of ViewStub as whole to be clickable and highlightable like a ListView elements? Also what do I have to add to get that orange highlight?

  • Fix elements within objects at their position? (Prevent movement when resizing)

    - by Skadier
    I would like to know if it is possible to fix elements at their absolute position within custom elements in InDesign CS5? I created a kind of speech bubble and I would like to place a stripline within this bubble to separate two content areas. Just a little scheme to show the desired layout as Pseudo-Markup :D <speech-bubble> <textbox>HEADER SECTION</textbox> <stripline> <textbox>Some other text</textbox> </speech-bubble> I created something like this but with two separate elements which aren't connected. So I have to select both of them in order to move the whole bubble. Then I tried to connect them using Object->Paths->Create linked path but then the stripline moves and the HEADER SECTION moves too. All in all I would like to have a speech bubble which can be resized in order to hold more text but it shouldn't make the HEADER_SECTION larger or move the stripline. Hope you understand what I mean :D Thanks in advance!
