combobox | regular combobox when you need suggesting values | Autocomplete library

For educational purpose I am using Python, Tkinter and Sqlite to create small prefabricated sentences, with small language templates like text.insert (tk.END, f "{City_Name} {is a city that owns} {Inhabitants} {inhabitants} {on a surface of} {Surface} "). The result should be (by way of example I remain the parentheses): {Paris} {is a city that owns} {2 229 095} {inhabitants} {on an area of} {105 km²}

The app starts with the selection of the Country in a combobox and then with the selection of the City in the combobox in the next combobox, for example "Paris", which in the database corresponds to City_Name. So the whole app focuses on city selection in the second combobox. So how can I retrieve from the row all the other data (Inhabitants, Name inhabitants, Surface, Language of the database) corresponding to "Paris", in order to automatically display them in the textobox, replacing them when requested?

To replace them when prompted automatically when prompted, I mean the curly brackets in text.insert, i.e. {Inhabitants}, {Surface}, etc.

IMPORTANT: In this way, I don't have to write the code for every single city, but I can write only one code that is valid for all the cities, because they automatically change {City_Name}, {Inhabitants}, {Surface}

P.S: I don't want to focus on a specific city, but obviously when you change the name of the city in the Combobox City, the data also changes (the row of data in the database), taking those corresponding to the selected city.

Can you please help me and show me the part of the code I need? Thank you

Everyone, I have made my own style and add this to qml.qrc then I calling it in main.cpp:

I have searched a lot for this topic and already found some approach but I get some errors I can't find the reason of it.

Idea is to read the keys from the enum with QMetaEnum to fill the strings in a combobox later.

I have already the enum and also setup Q_Object and Q_Enum Macro in the class where the enum is. But I am getting "undefined reference to 'Planet:: metaObject() const'" error message by using the QMetaEnum.

Here is the planet.h

I am new to Python. I'm having trouble executing an IF with a function inside. I enclose the code, including the graphic interface in Tkinter. In the same algorithm, I was wrong and i have difficulty in 2 things: write the correct IF conditions, and correctly call the Function inside IF, that is:

In vba, i read value from combobox but for decimal values it gets the 10 times of amount. It works fine for integers and it works on other peoples computers, im guessing something is wrong in my settings. Does anyone know how can i fix?

Here is the related code parts:

I ran the instructions from this question on stackoverflow. Credo di aver fatto tutto (o quasi) correttamente. I cannot understand what is wrong. No error in console/terminal. The problem is that the Combobox2 remains empty, after selecting the Combobox1.

Why does the combobox2 (City) remain empty, when I select a nation in combobox1 (Nation)? I would like the different names of each city for each selected nation to appear in combobox2 Thank you

In this minimal reproducible example, I have a comboBox and a pushButton. I am trying to activate buttons on the basis of current text selected from the comboBox, but I can't able activate buttons when I tried to verify it first inside if elif else condition, how to activate right function on the basis of current text.

I'm writing a GUI script to mapp network shares as drives. I have created (with the help of other SO users) a working combobox listing unused drive lettes. What I'd like to do now is to capture, after button click, selected combobox item into a variable to be used in another, not yet implemented part of script. So far I've managed to get the script to 'write-host' the selected item. Please help

In my code, I'M trying to filter a list of elements when an option is selected from a combobox. My code is below. Right now, the code doesn't have any errors, but I couldn't succeed on filtering the list. What should I do?
