  • Get highlighted state for NSButtonCell

    - by dvg
    I have a NSTableView that contains a NSButtonCell in one of the columns. To draw a custom background in neighbor cells (based on NSTextFieldCell) I use isHighlighted method: - (void)drawWithFrame:(NSRect)cellFrame inView:(NSView *)controlView { if ([self isHighlighted]) { //here I draw the cell background But for NSButtonCell isHighlighted shows only the button pressed state. How to determine when the NSButtonCell is selected, i.e. when it's highlighted in the row?

  • How to use the ListView_GetBkImage macro in C#

    - by MusiGenesis
    How can I use the ListView_GetBkImage macro: http://msdn.microsoft.com/en-us/library/bb761246(v=VS.85).aspx ... from a C#/WinForms application? I think this macro just wraps the SendMessage method, but I'm not sure. I couldn't find any C#-based samples on this. Basically I'm trying to get a LVBKIMAGE ( http://msdn.microsoft.com/en-us/library/bb774742(v=VS.85).aspx ) structure that references the Desktop's background bitmap.

  • Ruby (and Rails) nested module syntax

    - by brad
    I'm wondering what the difference is between the following two modules # First Example module Parent module Child end end and # Second Example module Parent::Child end Using the 2nd method, it appears as though the Parent module must be previously defined, otherwise I get an 'uninitialized constant' error Given this, what is the preferred way of defining modules such as this and then adding nested children with regards to syntax and file structure (ie. folders etc). Reference to a Rails way would be greatly appreciated. Are these two examples for all intents and purposes equivalent?

  • javascript instanceof get type from string name

    - by dcp
    Let's say I have this (assume the name variable is "receiver"): if (!(receiver instanceof com.HTMLReceiver)) { throw new com.IllegalArgumentException( name + " is not an instance of com.HTMLReceiver."); } I'd like to factor this code out into a common method so I could call it like this: Helper.checkInstance(receiver, "com.HTMLReceiver"); But I don't know of a way to convert the com.HTMLReceiver from a string to its actual type so I can use instanceof on it. Is there a way?

  • How can unwanted tags be removed from HTML using Nokogiri?

    - by sutch
    I need to strip out all font tags from a document. When attempting to do so with the following Ruby code, other elements and text within the font tags are lost. I've also attempted to iterate through all children elements and make them siblings of the font tag before unlinking the font tag--which also results in lost HTML. What is a good method for removing tags which can contain other elements and/or text? doc.css('font').each do |element| element.unlink end

  • Interesting task using random numbers only

    - by psihodelia
    Given any number of the random real numbers from the interval [0,1] is there exist any method to construct a floating point number with zero decimal part? Your algorithm can use only random() function calls and no variables or constants. No constants and variables are allowed, no type casting is allowed. You can use for/while, if/else or any other programming language operands.

  • 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; }

  • MySQL - Calculate the net time difference between two date-times while excluding breaks?

    - by John M
    In a MySQL query I am using the timediff/time_to_sec functions to calculate the total minutes between two date-times. For example: 2010-03-23 10:00:00 - 2010-03-23 08:00:00 = 120 minutes What I would like to do is exclude any breaks that occur during the selected time range. For example: 2010-03-23 10:00:00 - 2010-03-23 08:00:00 - (break 08:55:00 to 09:10:00) = 105 minutes Is there a good method to do this without resorting to a long list of nested IF statements?
