  • Is it possible to add a menu bar to a widget

    - by yan bellavance
    I would like to add a QMenuBar to a window of my program (not the QMainWindow) from QtDesigner but I do not see this widget in there and it seems the only way to do this from designer is to use a mainwindow. Would I absolutely need to create this QMenu by hand coding it. Is it possible/ok to instead add a QMainwindow that is actually declared inside my main QMainwindow?

  • Javascipt or jQuery "Are you sure?" dialog for <A> link?

    - by Andrew Tomazos - Fathomling
    I have a link in my HTML: <a href="/DoSomethingDangerous">do something dangerous</a> Visiting the DoSomethingDangerous link causes a not easily reversable action to occur. So after the link is clicked on I would like a dialog box (eg "Are you sure?" "OK" "Cancel") to be displayed and if the user clicks Cancel the link is not visited and the browser remains at the same page. What is the cleanest technique using either Javascript or jQuery to implement this?

  • Making a python script run at a set rate.

    - by Matt1024
    How can I make a python loop run at a set rate regardless of how long it takes to execute commands in the loop (providing the commands take less time to run than the loop is allowed)? How can I make this run every 0.25 seconds, for example? while True: print("OK")

  • How does timezone really work in relation to PHP and MYSQL?

    - by Rick
    I am getting very strange results in terms of timezones. I am currently using Wordpress and everytime I register a new user, I see the wrong datetime in the database. Ok so I am suspecting it is picking up the server time. So then I then set in php.ini to have date.timezone = "America/Los_Angeles" but again the time is still not correct in the database...And yes I have also set the timezone in Wordpress correctly. So how can this be done?

  • Resizing of AS-based Flash app from FireFox vs. IE...

    - by bferster
    I have put in some controls to allow users to resize my Flash app via Javascript: document.getElementById("flashApp").height*=1.25; document.getElementById("flashApp").width*=1.25; This works great in IE/Safari, but is ignored in Firefox. I know it's talking the the flash app and gets and sets the height/width vars ok, but the same code run in FireFox ignores the scaling. (It's not the DOC spec issue) Any thoughts? Bill

  • Are classes in Python in different files?

    - by Asaf
    Much like Java (or php), I'm use to seperating the classes to files. Is it the same deal in Python? plus, how should I name the file? Lowercase like classname.py or the same like ClassName.py? Do I need to do something special if I want to create an object from this class or does the fact that it's in the same "project" (netbeans) makes it ok to create an object from it?

  • Android: How to properly exit application when inconsistent condition is unavoidable?

    - by Bevor
    First of all I already read about all this discussion that it isn't a good idea to manually exit an Android application. But in my case it seems to be needed. I have an AsyncTask which does a lof of operations in background. That means downloading data, saving it to local storage and preparing it for usage in application. It could happen that there is no internet connection or something different happens. For all that cases I have an Exception handling which returns the result. And if there is an exception, the application is unusable so I need to exit it. My question is, do I have to do some unregistration unloading or unbinding tasks or something when I exit the application by code or is System.exit(0) ok? I do all this in an AsyncTask, see my example: public class InitializationTask extends AsyncTask<Void, Void, InitializationResult> { private ProcessController processController = new ProcessController(); private ProgressDialog progressDialog; private Activity mainActivity; public InitializationTask(Activity mainActivity) { this.mainActivity = mainActivity; } @Override protected void onPreExecute() { super.onPreExecute(); progressDialog = new ProgressDialog(mainActivity); progressDialog.setMessage("Die Daten werden aufbereitet.\nBitte warten..."); progressDialog.setIndeterminate(true); //means that the "loading amount" is not measured. progressDialog.setCancelable(false); progressDialog.show(); }; @Override protected InitializationResult doInBackground(Void... params) { return processController.initializeData(); } @Override protected void onPostExecute(InitializationResult result) { super.onPostExecute(result); progressDialog.dismiss(); if (!result.isValid()) { AlertDialog.Builder dialog = new AlertDialog.Builder(mainActivity); dialog.setTitle("Initialisierungsfehler"); dialog.setMessage(result.getReason()); dialog.setPositiveButton("Ok", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { dialog.cancel(); //TODO cancel application System.exit(0); } }); dialog.show(); } } }

  • Would a pointer to a pointer to nil match against NULL?

    - by dontWatchMyProfile
    Example: A validation method contains this check to see if an NSError object shall be created or not: - (BOOL)validateCompanyName:(NSString *)newName error:(NSError **)outError { if (outError != NULL) { // do it... Now I pass an NSError object, like this: NSError *error = nil; BOOL ok = [self validateCompanyName:@"Apple" error:&error]; I'm not sure if this matches the check for not NULL. I think it's not NULL, since I believe NULL is not nil. Maybe someone can clear this up?
