QUESTION
I am trying to read xml tags from a document using QtXQuery. Works out fine besides a '\n'-char that is attached to each query-result. Moreover using the last()-statement on a collection returns the expected number of items in the collection with a trailing repetition + '\n'. Why QXmlQuery seem to add a ` \n` to results? (and how to solve it?) suggest to use a QStringList and only take the first item into account, yet this does not seem to work with my setup as using a QStringList on query.evaluateTo(&qsl) fails to return any results. So: my question is if this is a bug in libqt5xmlPatterns5 or if my implementation is the reason for this behavior? Am I missing some details on how to use QtXmlQuery? So here is the piece of code:

QUESTION
Sorry if it is duplicate but i can't find anything usefull to me regarding Qt5. Is there any way to embed Xterm into Qt application using c++? I did it with python, but there is problem with resizing xterm on (at least with PyQt5) widget's container resize, in other words xterm doesn't resize, which is not acceptable.
So i want to try with Qt using c++. Python code (simplified) that worked was:
...ANSWER
Answered 2020-Jun-03 at 17:23The problem is that xterm does not have the "-embed" command (I don't know if it did) but you must use the "-into" command as the docs point out.
On the other hand, it is not necessary to access the tabwidget or create a QProcess pointer unnecessarily.
Considering the above then the solution is:
QUESTION
I am new and trying to learn qt and qml but I cannot find a way to solve this problem.
I have a QSqlTableModel with only 4 rows of test data, but I would like to convert distinct values from 1 column (of which there is only 1 value) into a list for a qml ListModel.
I have this Q_PROPERTY(QStringList distinctSemesters READ getSemesterList NOTIFY semesterChanged) in my SqlDataModel.h file, with this in my sqldatamodel.cpp
ANSWER
Answered 2020-Jan-22 at 01:07Explanation:
In your case the QSqlTableModel loads all the rows of the table since there is no filter so it will have 4 rows so any view that uses it will also show those 4 rows so the ListView shows 4 rows. Why does each row show the same information? Well, because in each item you have the delegate show the different "Semester" that are always "Spring 2020".
Solution:
In this case it is not necessary to use a QSqlTableModel since a QSqlQueryModel is enough to allow filtering from QML, so for this you can use the model of my other answer. So it will only be enough to place it in export to QML and use it.
QUESTION
I am making a small program for my job (it has nothing to do with programming) to help them with the many measurements and efficiency of their job.
I have made most of the program in a Console App in C++ with Code::Blocks.
Would it be possible to yank the output of variables from my C++ and put them in certain cells in an Excel spreadsheet? I have looked around the internet for some forums but some do not work or have me use Visual Basics. Any clues or hints would help dramatically. Thanks.

I've written an image editing application. It has a couple of its own image formats; I'd like it to open them if they are selected to open in finder.

QUESTION
I have a button that whenever it is pressed is supposed to increment by one, which as a result will display a new string into a textfield. I have a Core Data manager class that contains a method which is supposed to retrieve my arrays, however whenever I press the button the app crashes. I'm left with an error stating ...
...ANSWER
Answered 2017-Apr-22 at 20:42Your fetchAllRecords method returns an array of UsefulCodes objects. So each element of array is a UsefulCodes object. You cannot therefore assign the element to the text property of a textfield. That's the cause of your error.
You need instead to extract the relevant string from the UsefulCodes object. From your other code, you store the presetList values in the codename attribute of the UsefulCodes objects:
QUESTION
I have 2 NSMutableArrays and they will be used to fill table cells, I'm not sure if Core data can handle NSMutableArrays but is there a way to save these arrays with pre-existing data already in them? Would it also be possible to also add to these arrays later? My goal is to allow the user to add a new code and description at the same time, thus resulting in a new table cell being added. Here is how I created my two arrays could anyone show me how to put these in Core data?

QUESTION
I have a textfield on my MainViewController that I'd like to pass a string into from my TableViewController. Specifically when I select a cell (didSelectRowatIndexPath) I'd like to take the text for that indexpath.row and dismiss the TableViewController passing the string into the textfield on my MainViewController. I have attempted to create a delegate to get this to work but all it says in the debugging window is that the correct string is passing but never appears in the textfield... Here is my code showing everything necessary for the delegation.
My TableViewController.h where the delegate is declared...
...ANSWER
Answered 2017-Apr-05 at 05:39Possibly you set delegate to one instance of TableViewController and display another one.

ADIF format is described here: http://www.adif.org/ I'm trying to make Adif parser. Here is portion of Adif file to be parsed:
...ANSWER
Answered 2017-Mar-18 at 11:03You're missing logic to handle the header. Basically the header seems to be allowed to contain text including : which means you have to add a check, it a tag is being parsed to the case where you get a : char.
Furthermore you need to handle data types appropriately, since otherwise the type is simply appended to the size.
Also you should use StringBuilder instead of StringBuffer, since the latter also does synchronisation which just decreases the performance in this case without providing any benefits.
The following code also replaces some of the ifs with switch statements.
For simplicity it uses another record for the header data...
