  • Swing Panel Question

    - by dalton conley
    Ok, so I've been pulling my hair out over this all day. I cannot get my panels to resize. I add a panel to anything.. a frame, a content pane, and It wont .. "force" setBounds for some strange reason. Container pane = window.getContentPane(); JPanel calendarPanel = new JPanel(); pane.add(calendarPanel); calendarPanel.setBounds(0,0, 320, 335); note that window is of JFrame. Any suggestions to sizing a panel would be appreciated!

  • Undefined Behavior and Sequence Points Reloaded

    - by Nawaz
    Consider this topic a sequel of the following topic: Previous Installment Undefined Behavior and Sequence Points Let's revisit this funny and convoluted expression (the italicized phrases are taken from the above topic *smile* ): i += ++i; We say this invokes undefined-behavior. I presume that when say this, we implicitly assume that type of i is one of built-in types. So my question is: what if the type of i is a user-defined type? Say it's type is Index which is defined later in this post (see below). Would it still invoke undefined-behavior? If yes, why? Is it not equivalent to writing i.operator+=(i.operator ++()); or even syntactically simpler i.add(i.inc());? Or, do they too invoke undefined-behavior? If no, why not? After all, the object i gets modified twice between consecutive sequence points. Please recall the rule of thumb : an expression can modify an object's value only once between consecutive "sequence points. And if i += ++i is an expression, then it must invoke undefined-behavior. If so, then it's equivalents i.operator+=(i.operator ++()); and i.add(i.inc()); must also invoke undefined-behavior which seems to be untrue! (as far as I understand) Or, i += ++i is not an expression to begin with? If so, then what is it and what is the definition of expression? If it's an expression, and at the same time, it's behavior is also well-defined, then it implies that number of sequence points associated with an expression somehow depends on the type of operands involved in the expression. Am I correct (even partly)? By the way, how about this expression? a[++i] = i; //taken from the previous topic. but here type of `i` is Index. class Index { int state; public: Index(int s) : state(s) {} Index& operator++() { state++; return *this; } Index& operator+=(const Index & index) { state+= index.state; return *this; } operator int() { return state; } Index & add(const Index & index) { state += index.state; return *this; } Index & inc() { state++; return *this; } };

  • sqllite - sql question 101

    - by qstar
    Hi, I would do something like this* select * from cars_table where body not equal to null. select * from cars_table where values not equal to null And id = "3" I know the syntax for 'not equal' is <, but i get an empty results. For the second part, I want to get a result set where it only returns the columns that have a value. So, if the value is null, then don't include that column. Thanks

  • Does Parallel.ForEach require AsParallel()

    - by dkackman
    ParallelEnumerable has a static member AsParallel. If I have an IEnumerable<T> and want to use Parallel.ForEach does that imply that I should always be using AsParallel? e.g. Are both of these correct (everything else being equal)? without AsParallel: List<string> list = new List<string>(); Parallel.ForEach<string>(GetFileList().Where(file => reader.Match(file)), f => list.Add(f)); or with AsParallel? List<string> list = new List<string>(); Parallel.ForEach<string>(GetFileList().Where(file => reader.Match(file)).AsParallel(), f => list.Add(f));

  • DataGridView's top left cell value is not displayed.

    - by Spike
    I have a DataGridView, without visible row or column headers, and bound to a BindingList. No matter what I try the top left cell (Rows[0].Cells[0]) is always empty. The cell's Visible property is true, but it never displays its contents. If I make some rows and columns invisible, it's still the top left of the visible cells that isn't displayed.

  • Linq and Lamba Expressions - while walking a selected list perform an action

    - by Prescott
    Hey, I'm very new to linq and lamba expressions. I'm trying to walk a collection, and when I find an item that meets some criteria I'd like to add that to another separate collection. My linq to walk the collection looks like this (this works fine): From i as MyCustomItem In MyCustomItemCollection Where i.Type = "SomeType" Select i I need each of the select items to then be added to a ListItemCollection, I know I can assign that linq query to a variable, and then do a for each loop adding a new ListItem to the collection, but I'm trying o find a way to add each item to the new ListItemcollection while walking, not a second loop. Thanks ~P

  • Adding Parameters to Zend_Navigation

    - by Grant Collins
    I have a problem with Zend_Navigation that I am hoping for a little guidance on. I'm in the process of adding a Zend_Navigation to a legacy app as described [here on SO].1 The thing that I am not sure of is how to add parameters to the navigation menu after the data is loaded from the xml file. What I want to do is get 2 identifying parameters from the url and add them to the Zend_Navigation so that they are included in things such as the breadcrumb bar, so that if a user selects the previous item in the breadcrumb they are returned with the correct params in the url. The parameters, I believe need to be set at the Action level rather than the controller. Any help would be appreciated. Many thanks.

  • Is this the 'Pythonic' way of doing things?

    - by Sergio Tapia
    This is my first effort on solving the exercise. I gotta say, I'm kind of liking Python. :D # D. verbing # Given a string, if its length is at least 3, # add 'ing' to its end. # Unless it already ends in 'ing', in which case # add 'ly' instead. # If the string length is less than 3, leave it unchanged. # Return the resulting string. def verbing(s): if len(s) >= 3: if s[-3:] == "ing": s += "ly" else: s += "ing" return s else: return s # +++your code here+++ return What do you think I could improve on here?

  • Grouping records from while loop | PHP

    - by Wayne
    I'm trying to group down records by their priority levels, e.g. --- Priority: High --- Records... --- Priority: Medium --- Records... --- Priority: Low --- Records... Something like that, how do I do that in PHP? The while loop orders records by the priority column which has int value (high = 3, medium = 2, low = 1). e.g. WHERE priority = '1' The label: "Priority: [priority level]" has to be set above the grouped records regarding their level

  • Adding Listeners at runtime? - Java MVC

    - by Halo
    My model in my MVC pattern, generates components at runtime and gives them to the View to be displayed on the screen through update() method (you know, model is the observable and the view is the observer). But I also need to add listeners to these components, and the controller has the listener methods (because they say the MVC pattern is like this) and it's not involved in this update process. So I can't add the listeners at runtime, but only in the controller's constructor at startup. I've got an idea, that is making the controller the observer and then giving the data to the view, as well as adding the listeners. Do you think this would be OK?

  • concurrency in Java

    - by p1
    1]What is Non-blocking Concurrency and how is it different. 2] I have heard that this is available in Java. Are there any particular scenarios we should use this feature 3] Is there a difference/advantage of using one of these methods for a collection. What are the trade offs class List { private final ArrayList<String> list = new ArrayList<String>(); void add(String newValue) { synchronized (list) { list.add(newValue); } } } OR private final ArrayList<String> list = Collections.synchronizedMap(); The questions are more from a learning/understanding point of view. Thanks for attention.

  • Why does sorl.thumbnail ImageField fail in the admin?

    - by Mark0978
    I have code that looks like this: from sorl.thumbnail import ImageField class Gallery(models.Model): pass class GalleryImage(models.Model): image = ImageField(upload_to='galleries') In the admin: class GalleryImageInline(admin.TabularInline): model = GalleryImage class GalleryAdmin(admin.ModelAdmin): inlines = (GalleryImageInline,) If I use the sorl.thumbnail as above, it is impossible to add images in the admin. I get the validation error Enter a list of values. If I replace the sorl.thumbnail.ImageField with a plain django ImageField, everything works. If I want sorl.thumbnail to clean up the cache thumbnails, I need to use it in the model, but if I use it in the model, I can't seem to add any images to need thumbnails. Anyone else found and fixed this problem yet?
