In Eclipse CDT at DefaultBinaryFileEditor class, in the method getStorage there is a comment that tells the line objdump.getOutput(limitBytes) is a UI blocking call...
How can I make it run in background without UI Blocking to process longer files than it is stated with parameter int limitBytes = 6*1024*1024;
I can access org.eclipse.cdt.utils.Objdump class' getOutput method via plugin.xml extension point "org.eclipse.cdt.core.BinaryParser"...
I tried to replace the class that is used in extension point "org.eclipse.ui.editors" in editor tag with id "org.eclipse.cdt.ui.binaryEditor" via my plugin.xml, but this did not worked.
I put a boolean flag to outer class and in inner class BinaryFileEditorInput in method getStorage I put a Job and before this job works I created an empty fStorage = new FileStorage. I return this empty fstorage. So first the editor gets blank. Then when the objdump.getOutput(limitBytes) method returns in job, I set the fStorage to the returned output. I simply call the outer class'es refresh method. I put a reference of created outer class to inner static class in outerclasses constructor. This way I can access the refresh method. Also I moved fStorage varible to outerclass because refresh method triggers creating a new inner class so it overrides the valuable fStorage variable.
Finally If you want to update the opened elf file editor when you build the project again, assign the boolean variable and fStorage to first values in method resourceChanged before calling refresh method.

I am trying to create a button within a for loop as the loop is connected to the main dart. Everything else is running fine but then I try to put in the raisebutton I seem to get these errors depending on the dart package I am using stating:
package:path/path.dart Context context Type: Context
The system path context.
This differs from a context created with new Context in that its Context.current is always the current working directory, rather than being set once when the context is created.
or
dart:js JsObject get context
The JavaScript global object, usually window.
I don't know if what I am doing is right or not, please help.
Here is part of my main dart where the for loop is suppose to go inside as the for loop is within a different dart file
I'm not sure why you are instantiating MyMenu so often or why you are passing MyMenu instance variables into a MyMenu instance method. You may want to look at a better way to structure your code.
But to answer your question, you have no access to the current BuildContext within your MyMenu class. Quickest remedy: pass the BuildContext as a parameter to buildMenuItemsList.
buildMenuItemsList(Section section, BuildContext context) { ... }
MyMenu().buildMenuItemsList(MyMenu().getSections()[index], context),
Is it possible to dynamically create objects or modify them on run-time ?for example,on button click,another button created or change number of lines of a road?
When I write this code for a button Action,in run-time
road123.setBackwardLanesCount(3);
I get error below:
root:
road123: Markup element is already initiated and cannot be modified.Please use constructor without arguments,perform setup and finally call initialize() .function
You'll get that error with any object you attempt to create at runtime using a parameterized constructor. If you create the object with a simple constructor (just "()") and then set all of the parameters individually, you won't run into that issue. Check the Anylogic API for specific information about the object you are using, because some require you to call .initiliaze() on that object after setting all of it's parameters if you created it using a simple constructor. Furthermore, if you want to add the object to the screen at runtime you'll need to add this code to the function that creates it:
#Override
public void onDraw( Panel panel, Graphics2D graphics) {
obj.drawModel(panel, graphics, true);
}
where obj is replaced with the name of the object you created dynamically.
Trying to view specific portions of the parse tree inside of methods generated by ANTLR4 inside Eclipse Kepler Release. For instance ANTLR generates an 'enter/exit' method for a grammar rule created called FunctionDefinition.
Inside the FunctionDefinition method I'm able to getText from the child nodes inside context. Is there a way to graphically represent this context and it's child nodes, via a plugin etc.?
The FunctionDefinitionContext object returned from the parser extends RuleContext, so you can call inspect() on the object to view the result graphically.
FunctionDefinitionContext ctx = parser.functionDefinition();
Future<JDialog> futureDialog = ctx.inspect(Arrays.asList(parser.getRuleNames()));
// wait for the dialog to close (if you want)
Utils.waitForClose(futureDialog.get());
I currently have an event trigger firing a custom trigger action.
The action passes back a EventArgs type of object to the view's view-model.
This is all well and good when I run the code it works perfectly. However, when I come to test this portion of code it all goes a bit rubbish.
As stated We are using an MVVM type pattern so I'm testing the 'Doing' end of the event trigger in my view-model and what I want to do is create a 'mocked' EventArgs object to pass into the execute method of my command under test. However it requires a RoutedEvent as it's ID property as stated above and I don't have access to it's constructor!
Cannot Access Internal Constructor for 'RoutedEvent' here.
Has anyone got any ideas? The code converage in test is more important than the current implimentation so if this is thought to be 'untestable', then I can make changes.
I have answered my own Question I think.
Casting the object passed back from the view at an earlier point means that the object I am passing to the methods under test is more easily created.
This is what I have now for the method under test.
public void DoItemsChanged(IList param)
Before I had
public void DoItemsChanged(object param)
Where the param is a SelectedItemCollection (previously a RoutedEventArgs, but now I use the IvokeCommandAction on the event trigger in the view, passign the SelectedItems). The param is now more easily passed into the method for the test and the code it much more descriptive as well. So it's all good for everyone.
"core" refers to the initial piece of the application that is loaded.
In order to bind url to places, GWT uses PlaceTokenizer<P extends Place>. When loading the application from the url, it calls the method P getPlace(String token) to retrieve a new instance of the place to call.
due to the asynchronous nature of code splitting, I can't create the place inside a runAsync in this method. So I have to put all the places of my app in the core.
To link places to activity, GWT callsActivity getActivity(Place place) (from com.google.gwt.activity.shared.ActivityMapper) to retrieve a new instance of the activity.
Once again, i have to put all my activities in the core.
Here's what I want to try: Write a custom com.google.gwt.place.shared.Delegate that
bind itself on PlaceChangeRequestEvent. If the AppPiece corresponding to the requestedPlace isn't loaded, it calls event.setWarning(NEED_TO_LOAD_MODULE)
in the confirm(String message) method, always return false when the message equals NEED_TO_LOAD_MODULE (so it doesn't bother the user), and load the module via RunAsync.
Once the module is loaded, call goTo(requestedPlace)
Each AppPiece of my application contains a bunch of activies and the corresponding views. Since the mappers are only called when PlaceChangeEventis fired, i could generate a new instance of my activity via AppPiece.getSomeActivityInstance().
I'm pretty sure this will work, but what bother me is that
Finding wich AppPiece to load depending on the requestedPlace will force me to write code that will be very similar to my mappers
I would like to have my places inside the corresponding AppPiece
Overriding Delegate for this purpose is tricky, and I'm looking for a better solution
You don't have to put all your activities in the core (as you call it): while an Activity instance is retrieved synchronously, it's allowed to start asynchronously. This is where you'd put your GWT.runAsync call.
