  • Set Validation Tooltip in CodeBehind instead of XAML

    - by KrisTrip
    I would like to know how to translate the following code to codebehind instead of XAML: <Style.Triggers> <Trigger Property="Validation.HasError" Value="true"> <Setter Property="ToolTip" Value="{Binding RelativeSource={RelativeSource Self}, Path=(Validation.Errors)[0].ErrorContent}"/> </Trigger> </Style.Triggers> The part I can't figure out is the Path portion. I have the following but it doesn't work: new Trigger { Property = Validation.HasErrorProperty, Value = true, Setters = { new Setter { Property = Control.ToolTipProperty, // This part doesn't seem to work Value = new Binding("(Validation.Errors)[0].ErrorContent"){RelativeSource = RelativeSource.Self} } } } Help?

  • Problem creating gui from xml -> Strange CPButton behaviour

    - by Superpro
    Hallo, I'm new to objective-j and cappuccino and just have tried to create a small application, that creates the gui dynamically from a xml file. Unfortunately it works only partially. It seems that the button regions are disorder. This means, that the buttons also response if I click besides the button.... Please help me. I dont get it.. - (void)applicationDidFinishLaunching:(CPNotification)aNotification { mControlList = [CPArray alloc]; theWindow = [[CPWindow alloc] initWithContentRect:CGRectMakeZero() styleMask:CPBorderlessBridgeWindowMask], contentView = [theWindow contentView]; [contentView setFrame:[[contentView superview] bounds]]; [contentView setAutoresizingMask:CPViewWidthSizable | CPViewHeightSizable]; // Loadxmlfile var xhttp; if (window.XMLHttpRequest) { xhttp=new XMLHttpRequest() } else { xhttp=new ActiveXObject("Microsoft.XMLHTTP") } xhttp.open("GET","test.xml",false); xhttp.send(""); xmlDoc = xhttp.responseXML; //Get controls nodeand iterate through all controls var node = xmlDoc.getElementsByTagName("controls")[0]; for (var i=0; i<node.childNodes.length; i++) { if(node.childNodes[i].nodeName=="button"){ var item = node.childNodes[i]; var name = item.attributes["name"].nodeValue; var text = item.getElementsByTagName("text") [0].childNodes[0].nodeValue; var x= item.getElementsByTagName("rect") [0].attributes["x"].nodeValue; var y= item.getElementsByTagName("rect") [0].attributes["y"].nodeValue; var width= item.getElementsByTagName("rect") [0].attributes["width"].nodeValue; var height= item.getElementsByTagName("rect") [0].attributes["height"].nodeValue; var b = [[Button alloc] InitWithParent:contentView Text:text X:x Y:y Width:width Height:height]; [mControlList addObject:b]; } } [theWindow orderFront:self]; } @implementation Button : CPObject { CPButton _button; } - (Button)InitWithParent:(CPView)contentView Text:(CPString)text X: (int)x Y:(int)y Width:(int)width Height:(int)height { _button = [[CPButton alloc] initWithFrame: CGRectMake(x,y,width,height)]; [_button setTitle:text]; [_button setTarget:self]; [_button setAction:@selector(cmdNext_onClick:)]; [contentView addSubview:_button]; return self; } - (void)cmdNext_onClick:(id)sender { } @end

  • Django: text fixture fails to load

    - by Esteban Feldman
    Hi all, Did a dumpdata of my project, then in my new test I added it to fixtures. from django.test import TestCase class TestGoal(TestCase): fixtures = ['test_data.json'] def test_goal(self): """ Tests that 1 + 1 always equals 2. """ self.failUnlessEqual(1 + 1, 2) When running the test I get: Problem installing fixture 'XXX/fixtures/test_data.json': DoesNotExist: XXX matching query does not exist. But manually doing loaddata works fine does not when the db is empty. I do a dropdb, createdb a simple syncdb the try loaddata and it fails, same error. Any clue? Python version 2.6.5, Django 1.1.1

  • Django: order by count of a ForeignKey field?

    - by AP257
    This is almost certainly a duplicate question, in which case apologies, but I've been searching for around half an hour on SO and can't find the answer here. I'm probably using the wrong search terms, sorry. I have a User model and a Submission model. Each Submission has a ForeignKey field called user_submitted for the User who uploaded it. class Submission(models.Model): uploaded_by = models.ForeignKey('User') class User(models.Model): name = models.CharField(max_length=250 ) My question is pretty simple: how can I get a list of the three users with the most Submissions? I trued creating a num_submissions method on the User model: def num_submissions(self): num_submissions = Submission.objects.filter(uploaded_by=self).count() return num_submissions and then doing: top_users = User.objects.filter(problem_user=False).order_by('num_submissions')[:3] but this fails, as do all the other things I've tried. Can I actually do it using a smart database query? Or should I just do something more hacky in the views file?

  • Dynamically adding @property in python

    - by rz
    I know that I can dynamically add an instance method to an object by doing something like: import types def my_method(self): # logic of method # ... # instance is some instance of some class instance.my_method = types.MethodType(my_method, instance) Later on I can call instance.my_method() and self will be bound correctly and everything works. Now, my question: how to do the exact same thing to obtain the behavior that decorating the new method with @property would give? I would guess something like: instance.my_method = types.MethodType(my_method, instance) instance.my_method = property(instance.my_method) But, doing that instance.my_method returns a property object.

  • how to set a tableview delegate

    - by dubbeat
    Hi, I'm trying to use a tableview without using a nib and without using a UITableViewController. I have added a UITableView instance to a UIViewController Like So mytable = [[UITableView alloc] initWithFrame:CGRectMake(22, 207, 270, 233)]; [mytable setDelegate:self]; [self.view mytable]; Also I have added the following table view methods to my UIViewController (cut for brevities sake) - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { I am getting a warning saying that my UIViewController does not implement UITableView delegate protocol. Whats the correct way to tell the table view where its delegate methods are? (This is my first attempt at trying to use a UITableView without selecting the UITableTableview controller from the new file options)

  • Rails3 and safe nl2br !

    - by arkannia
    Hi, I have a system for the users to be able to post comments. The comments are grasped into a textarea. My problem is to format the comments with br tag to replace \n In fact, i could do something like that s.gsub(/\n/, '<br />') But the xss protection including in rails escapes br tags. So i could do this s.gsub(/\n/, '<br />').html_safe But then, all the tags are accepted even script.... causing a big security problem So my question is : how to format text with br safely ? Thanks EDIT: For now, i have add this def sanitaze self.gsub(/(<.*?>)/, '') end def nl2br self.sanitaze.gsub(/\n/, '<br />').html_safe end

  • python object to native c++ pointer

    - by Lodle
    Im toying around with the idea to use python as an embedded scripting language for a project im working on and have got most things working. However i cant seem to be able to convert a python extended object back into a native c++ pointer. So this is my class: class CGEGameModeBase { public: virtual void FunctionCall()=0; virtual const char* StringReturn()=0; }; class CGEPYGameMode : public CGEGameModeBase, public boost::python::wrapper<CGEPYGameMode> { public: virtual void FunctionCall() { if (override f = this->get_override("FunctionCall")) f(); } virtual const char* StringReturn() { if (override f = this->get_override("StringReturn")) return f(); return "FAILED TO CALL"; } }; Boost wrapping: BOOST_PYTHON_MODULE(GEGameMode) { class_<CGEGameModeBase, boost::noncopyable>("CGEGameModeBase", no_init); class_<CGEPYGameMode, bases<CGEGameModeBase> >("CGEPYGameMode", no_init) .def("FunctionCall", &CGEPYGameMode::FunctionCall) .def("StringReturn", &CGEPYGameMode::StringReturn); } and the python code: import GEGameMode def Ident(): return "Alpha" def NewGamePlay(): return "NewAlpha" def NewAlpha(): import GEGameMode import GEUtil class Alpha(GEGameMode.CGEPYGameMode): def __init__(self): print "Made new Alpha!" def FunctionCall(self): GEUtil.Msg("This is function test Alpha!") def StringReturn(self): return "This is return test Alpha!" return Alpha() Now i can call the first to functions fine by doing this: const char* ident = extract< const char* >( GetLocalDict()["Ident"]() ); const char* newgameplay = extract< const char* >( GetLocalDict()["NewGamePlay"]() ); printf("Loading Script: %s\n", ident); CGEPYGameMode* m_pGameMode = extract< CGEPYGameMode* >( GetLocalDict()[newgameplay]() ); However when i try and convert the Alpha class back to its base class (last line above) i get an boost error: TypeError: No registered converter was able to extract a C++ pointer to type class CGEPYGameMode from this Python object of type Alpha I have done alot of searching on the net but cant work out how to convert the Alpha object into its base class pointer. I could leave it as an object but rather have it as a pointer so some non python aware code can use it. Any ideas?

  • Core Data produces Analyzer warnings

    - by RickiG
    Hi I am doing the final touch ups on an app and I am getting rid of every compiler/analyzer warning. I have a bunch of Class methods that wrap my apps access to Core Data entities. This is "provoking" the analyzer. + (CDProductEntity*) newProductEntity { return (CDProductEntity*)[NSEntityDescription insertNewObjectForEntityForName:@"CDProductEntity" inManagedObjectContext:[self context]]; } Which results in an Analyzer warning: Object with +0 retain counts returned to caller where a +1 (owning) retain count is expected In the method that calls the above Class Method I have this: CDProductEntity *newEntity = [self newProductEntity]; Which results in an Analyzer warning: Method returns an Objective-C object with a +1 retain count (owning reference) Explicitly releasing or autoreleasing a Core Data entity is usually very very bad, but is that what it is asking me to do here? First it tells me it has a +0 retain count and that is bad, then it tells me it has a +1 which is also bad. What can I do to ensure that I am either dealing with a Analyzer hiccup or that I release correctly? Thanks in advance

  • How to get cell text based on indexPath?

    - by Sheehan Alam
    I have a UITabBarController with more than 5 UITabBarItems so the moreNavigationController is available. In my UITabBarController Delegate I do the following: - (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController { //do some stuff //... UITableView *moreView = (UITableView *)self.tabBarController.moreNavigationController.topViewController.view; moreView.delegate = self; } I want to implement a UITableViewDelegate so I can capture the row that was selected, set a custom view property and then push the view controller: - (void)tableView:(UITableView *)tblView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { //how can I get the text of the cell here? } I need to get the text of a cell when the user taps on a row.

  • iPhone Application: force landscape mode, strange behaviour...?

    - by David Lawson
    This is a method I use to switch display views, based on a string passed (for example you could pass MainMenuViewController to switch views to a new instance of that class): - (void)displayView:(NSString *)newView { NSLog(@"%@", newView); [[currentView view] removeFromSuperview]; [currentView release]; UIViewController *newView = [[NSClassFromString(newView) alloc] init]; [[newView view] setFrame:CGRectMake(0, 0, 320, 460)]; [self setCurrentView:newView]; [[self view] addSubview:[currentView view]]; } I have my application forced into landscape view (.plist and -shouldRotate), but if you look in the code: [[newView view] setFrame:CGRectMake(0, 0, 320, 460)]; I have to set the frame of the newView to a portrait frame for the view to be displayed correctly - otherwise, for example, a button on the new view can only be pressed in certain parts of the screen (rectangle up the top), unresponsive anywhere else. Even though in all my NIB files they are set to landscape.

  • Merge a hash with the key/values of a string in ruby

    - by LazyJason
    Hi there, I'm trying to merge a hash with the key/values of string in ruby. i.e. h = {:day => 4, :month => 8, :year => 2010} s = "/my/crazy/url/:day/:month/:year" puts s.interpolate(h) All I've found is to iterate the keys and replace the values. But I'm not sure if there's a better way doing this? :) class String  def interpolate(e)    self if e.each{|k, v| self.gsub!(":#{k}", "#{v}")}  end end Thanks

    Hey guys, I declared a NSMutableArray in the header-file with: NSMutableArray *myMuArr; and @property (nonatomic, retain) NSMutableArray *myMuArr; In the .m file I've got a delegate from an other class: -(void)didGrabData:(NSArray*)theArray { self.myMuArr = [[[NSMutableArray alloc] initWithArray:myMuArr]retain]; } If I want to access the self.myMuArr in cellForRowAtIndexPath it's empty (I checked the retain count of the array and it's 0) What am I doing wrong? Of course it's released in the dealloc, no where else. I would be very thankfull for any help :0)

  • Python:How to override inner class methods if the inner class is defined as a property of the top cl

    I have a code snippet like this class A(object): class b: def print_hello(self): print "Hello world" b = property(b) And I want to override the inner class 'b'(please dont worry about the lowercase name) behaviour. Say, I want to add a new method or I want to change an existing method, like: class C(A): class b(A.b): def print_hello(self): print "Inner Class: Hello world" b = property(b) Now if I create C's object as c = C(), and call c.b I get TypeError: 'property' object is not callable error. How would I get pass this and call print_hello of the extended inner class? Disclaimer: I dont want to change the code for A class.

  • Eager load this rails association

    - by dombesz
    Hi, I have rails app which has a list of users. I have different relations between users, for example worked with, friend, preferred. When listing the users i have to decide if the current user can add a specific user to his friends. -if current_user.can_request_friendship_with(user) =add_to_friends(user) -else =remove_from_friends(user) -if current_user.can_request_worked_with(user) =add_to_worked_with(user) -else =remove_from_worked_with(user) The can_request_friendship_with(user) looks like: def can_request_friendship_with(user) !self.eql?(user) && !self.friendships.find_by_friend_id(user) end My problem is that this means in my case 4 query per user. Listing 10 users means 40 query. Could i somehow eager load this?

  • iPhone - Cannont access to an IBOutlet (nil valued)

    Hello, I have a problem acessing a IBOutlet. I have a NIB inside which there is a tableview, a toolbar and an UILabel (encasulated into a view). The controller (that is the file's owner) is defined as : @interface ChoixPeriodeController : UIViewController <UITableViewDelegate> { IBOutlet UILabel* __periodeInitialeLabel; } @property(nonatomic, retain) UILabel* periodeInitialeLabel; - (void) setSelectedPeriode:(Tache_TypePeriode)typePeriode; In the .m file, this function is called by the parent window to init the Label : - (void) setSelectedPeriode:(Tache_TypePeriode)typePeriode { NSMutableString* tmpString = [NSMutableString string]; [tmpString appendFormat:bla bla bla;....]; self.periodeInitialeLabel.text = tmpString; } Into this function, I can see that self.periodeInitialeLabel is at nil. I can't see why ? Everything is connected into IB... Do you see what can be the problem ?
