  • C++, class as parameter to a method, not template.

    - by ra170
    So, I came across an interesting method signature that I don't quite understand, it went along the lines of: void Initialize(std::vector< std::string > & param1, class SomeClassName * p); what I don't understand is the "class" keyword being used as the parameter, why is it there? Is it necessary to specify or it is purely superficial?

  • Create a custom button

    - by Beppi Menozzi
    Sorry if this is too basic. I created a new class that extends Button: public class MyButton extends Button { private Context ctx; public MyButton(Context context) { super(context); ctx = context; } private void click() { // DO WHAT I NEED (FOR EXAMPLE CHANGE BACKGROUND) } } How can make it possible that, when I setOnClickListener() from another class where I instantiated this object, the click() method is called automatically? Thanks.

    - by user525004

  • How do get the view that is the tapped detail-disclosure-button.

    - by Roberta
    The cell in this iPhone TableView definitely has a Detail-Disclosure-Button. When I tap it... shouldn't this code give me access to the button? Instead detailButton is always just null. - (void) tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath { UITableViewCell *aCell = [tableView cellForRowAtIndexPath:indexPath]; UIButton *detailButton = (UIButton *)[aCell accessoryView]; }

  • Difference between [object variable] and object.variable in Obj-C?

    - by John Smith
    I was working on a program today and hit this strange bug. I had a UIButton with an action assigned. The action was something like: -(void) someaction:(id) e { if ([e tag]==SOMETAG) { //dostuff } } What confuses me is that when I first wrote it, the if line was if (e.tag==SOMETAG) XCode refused to compile it, saying error: request for member 'tag' in 'e', which is of non-class type 'objc_object*' but I thought the two were equivalent. So under what circumstances are they not the same?

  • Ternary operators in C#

    - by pm_2
    With the ternary operator, it is possible to do something like the following (assuming Func1() and Func2() return an int: int x = (x == y) ? Func1() : Func2(); However, is there any way to do the same thing, without returning a value? For example, something like (assuming Func1() and Func2() return void): (x == y) ? Func1() : Func2(); I realise this could be accomplished using an if statement, I just wondered if there was a way to do it like this.

  • Test if a method is an override?

    - by Water Cooler v2
    Is there a way to tell if a method is an override? For e.g. public class Foo { public virtual void DoSomething() {} public virtual int GimmeIntPleez() { return 0; } } public class BabyFoo: Foo { public override int GimmeIntPleez() { return -1; } } Is it possible to reflect on BabyFoo and tell if GimmeIntPleez is an override?

  • Strange issue with cout

    - by ben
    After reading from a text file, and storing it into a string, I tried to pass this message into another function that will print it out. This is what it looks like: http://imgur.com/MCjfRdp void insert (int id, string message){ cout << "Inserting " << message << " at" << endl; } Somehow the message behind the string overrides the message. But once I removed the " at" after message, it worked as expected. http://imgur.com/JdHPPmi void insert (int id, string message){ cout << "Inserting " << message << endl; } I somehow suspect the problem came from stringstream, but i couldn't find out where. Here's the code that read from file vector <string> line; fstream infile; string readLine, tempLine, action, tempLine1; int level, no; infile.open(fileName.c_str(),ios::in); int i = 0; while (!infile.eof()) { getline (infile, readLine); line.push_back(readLine); } infile.close(); line.pop_back(); for (int i = 0; i < line.size();i++) { stringstream ss (line.at(i)); getline (ss, action, ' '); if (action == "init") { // some other work here } else if (action == "insert") { tempLine = line.at(i); ss >> no; stringstream iline(tempLine); getline (iline, tempLine1, ' '); getline (iline, tempLine1, ' '); getline (iline, tempLine1, '\n'); Insert (no, tempLine1); } Since my file has different kinds of actions, here is what test.dat contains: insert 0 THIS IS A TEST edit: When i did file.txt, it came out as something like this. Inserting THIS IS A TEST at Inserting THIS IS TEST NO 2 at

  • this parameter modifier in C#?

    - by Ivan
    I'm curious about this code snippet: public static class XNAExtensions { /// <summary> /// Write a Point /// </summary> public static void Write(this NetOutgoingMessage message, Point value) { message.Write(value.X); message.Write(value.Y); } // ... }; What does the this keyword mean next to the parameter type? I can't seem to find any information about it anywhere, even in the C# specification.
