I'm trying to get the position of the cursor by calling the mouse class and using the GetState method but the return value is always 0,0. I've searched everywhere and all the code looks the same on other examples. I've tried alternative ways of declare the class but I get the same results.
public void Update() {
var ms = Mouse.GetState();
cursorPos = new Vector2(ms.X, ms.y);
}
If you are using Mono, it's possible that Mouse.GetState method is extended. On some past versions there was problems Mouse.SetState method, could be that also problem was also in Mouse.GetState... so I suggest you take latest Mono framework.
Or you can try to access directly to that method.
var ms = Microsoft.Xna.Framework.Input.Mouse.GetState();
var mp = new Point(ms.X, ms.Y);

I recently switched to Java 11 for a rather big project, and would like to switch to using var class = new Class() instead of Class class = new CLass().
I tried using Intellij Structural Search (and replace) for this, but its turning out to be more complex than expected.
My first attempt was $Type$ $Inst$ = new $Constructor$($Argument$);, which also matches global variables (which don't allow var).
My second attempt is:
class $Class$ {
$ReturnType$ $Method$ ($ParameterType$ $Parameter$) throws $ExceptionType$ {
$Statements$;
final $Type$ $Inst$ = new $Constructor$($Argument$);
$Statements2$;
}
}
Which misses all calls inside e.g. try blocks (since they get matched by the expressions)
Any help would be greatly appreciated!
Use your first template
$Type$ $Inst$ = new $Constructor$($Argument$);
But add a Script modifier on the $Inst$ variable with the following text:
Inst instanceof com.intellij.psi.PsiLocalVariable
Alternatively you may want to try the Local variable type can be omitted inspection that is available in IntelliJ IDEA.
I am trying to implement 2 AutoCompleteTextView. First one holds the value, on click of one of them will populate the data in second AutoCompleteTextView, all works and data gets loaded correctly however when I try to call notifyDataSetChanged on the second adapter which populates the second field that does not get changed.
I also wrote that piece of code inside a Handler too, however that does not seems to work either.
branchAdapter = new ArrayAdapter(this,android.R.layout.simple_list_item_1,branchNames);
et7.setAdapter(branchAdapter);//et7 is the AutoCompleteTextView //branchname is the ArrayList
in some method I clean up the ArrayList and add the new data into it and then call notifyDataSetChanged like below
Handler handler = new Handler(Looper.getMainLooper());
handler.post(new Runnable() {
#Override
public void run() {
branchAdapter.notifyDataSetChanged();
}
});
Which is not updating the list. What should be the correct way here to update data?
#Saty, I guess i am a little late to the party. I am answering, keeping in mind that, it may help somebody in future.
Cleanup the adapter as well using branchAdapter.clear() method. Then add new items to the adapter using branchAdapter.addAll(String... items) method. Now, call branchAdapter.notifyDataSetChanged() method. This will work.
Try resetting listview instead.
ListView lv = (ListView)findViewById(R.id.lv);
ArrayAdapter adapter = new ArrayAdapter(/*with all parameters*/);
lv.setAdapter(adapter);
I'm trying to use a single controller to list multiple similar collections so I can call different templates with the same controller. In fact, right now I have 6 controllers for listing and another 6 for forms but they're all duplicates.
I've made a non-functional plunker just to show how I intend it to work. I've avoided declaring routeProviders because knowing it wouldn't work I tried to make it as straight to the point as I could.

I've seen on stackoverflow how to declare a class with a dynamic name:
var str = "MyClass";
var obj = new window[str];
But as I have not been able to find where it's stored I'm not able to retrieve it.
Does anyone have a hint on how to do this?
You can use Angular's injector to return the service instance you want. For example:
app.controller('NodeListCtrl', function($scope, $location, $injector) {
var modelName = $location.path().split("/")[1];
$scope.modelName = modelName.charAt(0).toUpperCase() + modelName.slice(1);
$scope.nodes = $injector.get($scope.modelName).query();
});
Note: Don't forget to add the $injector to the controller's function signature.

I am using RhinoMocks 3.6 and would like to use the multimock feature to implement both a class and a interface.
var mocks = new MockRepository();
var project = mocks.StrictMultiMock(
typeof(Project),
typeof(INotifyCollectionChanged));
using (mocks.Record())
{
((INotifyCollectionChanged)project).CollectionChanged += null;
LastCall.Constraints(Is.NotNull()).Repeat.Any();
}
The LastCall is working though. I get this message :
System.InvalidOperationException : Invalid call, the last call has been used or no call has been made (make sure that you are calling a virtual (C#) / Overridable (VB) method).
What am I doing wrong here??
Have you actually checked that the Project class has methods you can override as the error message indicates? I'll assume you have. :-)
I'd suggest you switch to using the AAA syntax instead of record/replay as shown here:
I assume you're wanting to know if the class under test reacts the right way when the CollectionChanged event is fired? If that's the case, you can do it something like this:
var project = MockRepository.GenerateMock<Project, INotifyPropertyChanged>();
project.Expect(p => p.SomeMethod())
.Repeat.Any()
.Raise(p => ((INotifyCollectionChanged)p).CollectionChanged += null,p,new NotifyCollectionChangedEventArgs());
when using a cellbrowser and adding that widget to a flowpanel (to be placed wherever, downstream), for some reason the end result is dead (a blank screen)...vs if I add directly to the rootpanel (or layout panel)
Also had the same problem. I had to use a <g:HTMLPanel> as the parent of the CellBrowser (as seen in the GWT Showcase).
Do you have some sample code that will reproduce this?
below is the code for the composite...essentially, what I'd like to do is in another class, attached this composite to a flowpanel and do whatever with it...but, the reality is, I have to attach is directly to the RootPanel (or RootLayoutPanel)...any other abstraction causes it to bail
for example
FlowPanel fp = new FlowPanel();
V2_M76Rolodex v = new V2_M76Rolodex();
fp.add(v); // not going to work
RootPanel.get.add(v) works
public class V2_M76Rolodex extends Composite {
/*
a bunch of code here for getting data and
populating the tree - works, not at issue or relevant
*/
public V2_M76Rolodex() {
TreeViewModel model = new CustomTreeModel();
CellBrowser browser = new CellBrowser(model, null);
browser.setKeyboardSelectionPolicy(KeyboardSelectionPolicy.ENABLED);
browser.addStyleName("rolodex_cell_browser");
initWidget(browser);
}
}
