There are two issues here. First the default visibility should be specified in the style. But even with that it won’t work because the binding on the trigger is comparing a SelectedValue, a ComboBoxItem object with a string object and that will never be equivalent. To keep the example simple, I’ve placed appropriate values in … Read more
1) Do not call Play() from the view model. Raise an event in the view model instead (for instance PlayRequested) and listen to this event in the view: view model: public event EventHandler PlayRequested; … if (this.PlayRequested != null) { this.PlayRequested(this, EventArgs.Empty); } view: ViewModel vm = new ViewModel(); this.DataContext = vm; vm.PlayRequested += (sender, … Read more
You don’t need to make any converter. Add a binding to a Visibility property for the border: <Border x:Name=”Border1″ Visibility=”{Binding Visibility}” BorderBrush=”Black” BorderThickness=”1″ HorizontalAlignment=”Left” Height=”21″ Margin=”229,164,0,0″ VerticalAlignment=”Top” Width=”90″ Opacity=”0.5″> <Grid> <Label Content=”test”/> </Grid> </Border> And then create the Visibility property in your ViewModel: private Visibility visibility; public Visibility Visibility { get { return visibility; } … Read more
For models, the idea is that the public methods are the public interface of the class. Public methods are intended to be used by other objects, while protected/private methods are to be hidden from the outside. This is the same practice as in other object-oriented languages. For controllers and tests, just do as you please. … Read more
I have a feeling that this error is unwarranted. It should only be an error if my_mod is pub or if the functions are re-exported in an outer scope. That said, I found a workaround: move MyStruct to a sibling module and make MyStruct pub, but not the module. use types::MyStruct; mod types { pub … Read more
Inheriting/overriding private methods In PHP, methods (including private ones) in the subclasses are either: Copied; the scope of the original function is maintained. Replaced (“overridden”, if you want). You can see this with this code: <?php class A { //calling B::h, because static:: resolves to B:: function callH() { static::h(); } private function h() { … Read more
Kotlin, compared to Java, seems to rely on packages model to a lesser degree (e.g. directories structure is not bound to packages). Instead, Kotlin offers internal visibility, which is designed for modular project architecture. Using it, you can encapsulate a part of your code inside a separate module. So, on top level declarations you can … Read more
Add a few calls to the chain like this: $(‘.littleme’).css(‘visibility’,’visible’).hide().fadeIn(‘slow’); This will change it to display:none for 1 frame before fading in, occupying the area again.
The constructor of PetStore will call a constructor of Farm; there’s no way you can prevent it. If you do nothing (as you’ve done), it will call the default constructor (Farm()); if you need to pass arguments, you’ll have to specify the base class in the initializer list: PetStore::PetStore() : Farm( neededArgument ) , idF( … Read more
The difference is that Visibility.Hidden hides the control, but reserves the space it occupies in the layout. So it renders whitespace instead of the control. Visibilty.Collapsed does not render the control and does not reserve the whitespace. The space the control would take is ‘collapsed’, hence the name. The exact text from the MSDN: Collapsed: … Read more
