I'm having trouble in testing an RCP application with Sleak because it does not display anything, it only shows the message "WARNING: Device is not tracking resource allocation".
I've setup Sleak from this tutorial and I don't know what's wrong.
Does anyone know a solution for this? Thanks in advance.
Do you have the correct version? Can you see the sleak view in your RCP-application? If not make sure it's in your launch configuration. Also double check that you have set the
org.eclipse.ui/debug=true
org.eclipse.ui/trace/graphics=true
correct in the tracing tab. There are properties with similar names.
You can write
org.eclipse.ui.internal.misc.Policy.DEBUG_SWT_GRAPHICS = true;
org.eclipse.ui.internal.misc.Policy.DEBUG_SWT_DEBUG = true;
before
Display display = PlatformUI.createDisplay();
This will create in Workbench.createDisplay() method
new Display with data tracking.

I have some extensions code in extension.ts
const item = vscode.window.createStatusBarItem(
vscode.StatusBarAlignment.Right
);
item.command = "codevids-auth.pushToWebview";
item.text = "$(record) codevid";
item.show();
I can't figure out how to place the statusBatItem in automatically without having to fire the command. Is this possible since some plugins as soon as they are installed they show up in the statusbar. I would like to know how to do this.
Thanks for the help ahead of time. And please let me know if you need more details I am happy to explain further.
It sounds like you may not be using an activationEvent which would trigger your extension's activate function immediately after startup is finished. Try this:
"activationEvents": [ "onStartupFinished" ]
Then your code, which includes .show(), should be sufficient to show the StatusBarItem soon after vscode is reloaded or started. It is typical that installation of an extension is not enough to activate it, the user should get a badge on the Extension view that reload is required. If that is what you are trying to avoid, I don't think it is possible.
I need a way to make my app close and opens again. Or just restart everything inside of it.
Since the issue with my app can be fixed by closing app and opening again (When creating user the loading function to firebase the collection inside user document does not load for some reason)
Below code can do it:
val context = LocalContext.current
val packageManager: PackageManager = context.packageManager
val intent: Intent = packageManager.getLaunchIntentForPackage(context.packageName)!!
val componentName: ComponentName = intent.component!!
val restartIntent: Intent = Intent.makeRestartActivityTask(componentName)
context.startActivity(restartIntent)
Runtime.getRuntime().exit(0)
So... you could write ways to "restart everything", but I am going to strongly suggest not doing that. When building an app, you will run into edge cases. You will hit some failure states that you can't recover from. That happens. But, solving these cases by just "restarting" doesn't actually address the issue and will probably result in wonky and undesirable UX.
I would instead suggest you post here some steps to reproduce and debugging results.
Under what circumstance/flow does this document stop loading?
When it does happen, can you capture the call to Firebase where it is trying to load the document?
If so, what does that call look like?
Is it looking for the document in the correct place?
Can you show an example of the call when it fails and also what the database hierarchy looks like?
Can you show us a snippet of code where this is failing?
Without more information, this sounds more like a race condition - you might be trying to find the document before it is actually created and not handling the error path for when the document is not found. However, we would need to do some debugging to verify.
Question
How to use these private functions on other windows? It would be nice to have this knowledge back in the wild. I am specifically trying to get CGSOrderWindow and CGSSetWindowLevel to work.
I was trying in the direction of:
temporarily register as the dock and then register the dock as the dock again immediately afterwards
or
code injection into the Dock process per this comment:
Also, the author of the above project seems determined to make all core functionality available as a framework. It seems to be implemented as code injection into the Dock process.
Reason I know this is possible
I have been doing work on trying to setLevel on window of another app, and focus window of another app if focused. I am posting this again with the info I learned because from my searching online, I know this was done in the past, its just the knowledge is not publicly out there anymore. The sourceforge pages are no longer there. So I was wondering if you could help me make this information public again.
This is the topic I read that gave me this information - http://cocoadev.com/HowtoControlOtherAppsWindows
Here you see comments like:
You cannot control an another app's windows from a user-level process, unfortunately.
SlavaKarpenko
You can, Slava, you just need to register as the Dock. It might be possible to temporarily register as the dock and then register the dock as the dock again immediately afterwards, not sure. I think the call you'd be wanting to investigate as CoreDockRegisterDockOwner in HIServices.framework.
FinlayDobbie
You could also use APE or similar to do control the windows, or (as mentioned above) register as the Dock (look for the private APIs with Universal Connection in their name). Has anyone found a polite way of getting the Dock to give up its universal connection? The only way I can find is to force quit the Dock and grab the universal connection when it's not looking (which prevents the dock reloading).

There's an open source project up on sourceforge.net that looks much more like the window managers I've used on Unix boxes than Space.app (or Space.dock): http://wsmanager.sourceforge.net/

Verifying things work
This is what I learned, from the sources at bottom of this post, we see all these functions work with CGWindowIds, so how do I get that, this is how:
Get all windows with CGWindowListCopyWindowInfo. Then access each element from that array with CFArrayGetValueAtIndex and then get the CGWindowId with objectForKey:, kCGWindowNumber, and then integerValue.
Now if I try to focus or set level of a window that is OWNED by the app running the code, it works fantastic. For instance:
MY_TARGET_CGWINDOW_ID = 179;
rez_CGError = CGSOrderWindow(_CGSDefaultConnection, MY_TARGET_CGWINDOW_ID, kCGSOrderAbove, 0);
Will focus it, rez_CGError is 0. Even if the window is minimized, it is unminimized, without animation, and shown.
Now however, if I try this on a window of a different app we get some errors:
MY_TARGET_CGWINDOW_ID_of_other_app = 40;
rez_CGError = CGSOrderWindow(_CGSDefaultConnection, MY_TARGET_CGWINDOW_ID_of_other_app, kCGSOrderAbove, 0);
This fails and rez_CGError is 1000, which I suspect means "cid (CGSConnection) used does not have permission to modify target window". The same happens if I first do [app activateWithOptions: (NSApplicationActivateIgnoringOtherApps | NSApplicationActivateAllWindows)] before making the call above.
So I first get the cid of that owning window like this:
var rez_CGError = CGSGetWindowOwner(_CGSDefaultConnection, MY_TARGET_CGWINDOW_ID_of_other_app, &ownerCid);
This works good and I get ownerCid is set to a value. Then I do the focus command with this new connection:
rez_CGError = CGSOrderWindow(ownerCid, MY_TARGET_CGWINDOW_ID_of_other_app, kCGSOrderAbove, 0);
However this gives rez_CGError of 268435459, which I suspect means "current app does not have permission to use this ConnectionId (cid)". (Same happens if I call activateWithOptions first.
My Sources for the Private Functions
Here is the sources for some private functions I found - https://code.google.com/p/undocumented-goodness/source/browse/trunk/CoreGraphics/CGSPrivate.h
This one source here contains a function that is not in the above link - CGSGetConnectionIDForPSN - i test it and it exists - from - https://github.com/mnutt/libqxt/blob/767498816dfa1742a6f3aee787281745afec11b8/src/gui/qxtwindowsystem_mac.h#L80
is it possible to for example - write a background service, which randomly changes the windows phone theme, I mean is it possible to access the windows phone theme under settings via code? and change it?
if so can you please give me an example of the API's I can use or additional libraries I can dl
thank you
Unfortunately you can't. It is not possible to change the Windows Phone theme by code. The only one who can is the user. This is part of the Windows Phone concept.
The only thing you can do is defining themes that are used in your own apps.
Sorry for the bad news...
You are allowed to change the theme for your application. There is a Nuget package available that makes this even easier. You could accomplish changing it in a background task by setting a property that you check when the app opens.
// background agent code
// get random value
IsolatedStorageSettings.ApplicationSettings["Theme"] = randomValue; // this is just a string or something simple
IsolatedStorageSettings.ApplicationSettings.Save();
When your app opens, you would check this value
var theme = "Standard";
if(IsolatedStorageSettings.ApplicationSettings.ContainsValue("Theme"))
{
theme = IsolatedStorageSettings.ApplicationSettings["Theme"];
// Set the theme
}
You can modify the source of the Theme Manager by downloading the source from github. Here is some more info on the Theme Manager. If you would like to change values yourself, you can accomplish this by setting the resource values when the papp starts
((SolidColorBrush)Resources["PhoneAccentBrush"]).Color = myAccentBrush;
((SolidColorBrush)Resources["PhoneBackgroundBrush"]).Color = myBackgroundBrush;
((SolidColorBrush)Resources["PhoneChromeBrush"]).Color = myChromeBrush;
((SolidColorBrush)Resources["PhoneForegroundBrush"]).Color = myForegroundBrush;
I would like to be able to gather info like how often certain windows are opened, what types of user data are accessed, how often menu items are clicked, etc. Does anyone know of a 3rd party (open source or commercial) Cocoa/Obj-C library or plugin that would allow me to gather this info?
I have used pinch media in the past, and they merged with Flurry. Library was simple to use and was setup in around 40 minutes.
I don't know any library for that but at least to get informed about when the user switches the front application you can install an event handler like this:
EventTypeSpec eventType;
eventType.eventClass = kEventClassApplication;
eventType.eventKind = kEventAppFrontSwitched;
EventHandlerUPP handlerUPP = NewEventHandlerUPP(FrontAppSwitchedDetector_callback);
OSStatus status=InstallApplicationEventHandler(handlerUPP,1,&eventType,self,&_eventHandlerRef);
... and when receiving an callback you may get the current front application process:
pascal OSStatus FrontAppSwitchedDetector_callback(EventHandlerCallRef nextHandler,EventRef theEvent,void* userData)
{
ProcessSerialNumber newSerial;
GetFrontProcess(&newSerial);
//to something with that ....
return (CallNextEventHandler(nextHandler, theEvent));
}
