I'm using a QLineEdit widget to enter email addresses and I set up a QRegExpValidor to validate the entry.

The validator is working as far as preventing the input of characters not allowed in the QRegExp, but funny enough, it allows to enter intermediate input, either by pushing the enter key or by firing the "editingfinished" signal.

I verified the return of the validator which is correct (Intermediate or Acceptable).

Checking the PyQt5 documentation it seams that an intermediate state of the validator does not prevent the focus to change to another widget. Furthermore, it stops the firing of the editingFinished and returnedPressed signals so the user may enter wrong address as far as it marches partially the RegExp. Ref: https://doc.qt.io/qt-5/qlineedit.html#acceptableInput-prop

I was able to solve my needs by removing the validator from the QLineEdit widget, and placing a method "checkValidator" linked to the cursorPositionChanged of the QLineEdit widget discarting the last character entered when nonacceptable, and setting the focus back to the QLineEdit when it validats intermmediate. It works just fine but when the the focus was reset, the others signals on other widgets were fired one at a time. Momentarily, I handle this by checking if the sender has focus at the start of the methods (see lookForFile)

Even though I could handle the issue, I appreciate very much anybody explaining me the proper way to use the RegExpValidator and or why resetting the focus fires the other signals out of the blue.

I need to find some image on screen. I decided to make a simple comparing loop.

I found this answer that seems to be helpfull and wrote the next code:

...

I want the send-button (id="Button1") to send a mail only when the caption is correct (string1 === string2). How and were, do I get this to work, in the button itself or in the script?

I also not want the popup to show telling me "TRUE", same with false, I do want the "alert" to open and tell me when its wrong, but not sign after that telling me "FALSE". I have tried without the "return false;" and "return true;", but that only gives me "undefined". EDIT: Just fixed this, I didn't realised I had "alert(ValidCaptcha());" it should be "ValidCaptcha();". But still need help with the first question.

This question seems hard to phrase, but after explaining my situation it should be easy to understand. I have two tables: one called INSTRUCTORS that holds instructor data and another called LIST_OPTION_ITEM that holds the ID values of different ID columns stored in the INSTRUCTORS table. A third and possibly important table to include is LIST_OPTION_TYPE, which contains the IDs of whatever ID column there is in INSTRUCTORS. Perhaps it would be easier to explain by showing sample data and my desired output.

INSTRUCTORS

RANK_ID SPECIALTY_ID DUTY_TITLE_ID SERVICE_BRANCH_ID STATUS_ID UNIT_ID OFFICE_SYMBOL_ID 1354 319 931 2604 1378 1406 1429

LIST_OPTION_ITEM

OPTION_ITEM_ID OPTION_TYPE_ID ITEM_VALUE 1354 22 CAPT 319 20 CBRN TRAUMA NURSE 931 21 IDMT-Squadron Medical Element 2604 128 46N NURSE 1378 23 USA 1406 24 Guard 1429 126 CERFP

LIST_OPTION_TYPE

OPTION_TYPE_ID OPTION_TYPE 20 Specialty 21 Duty_Title 22 Rank 23 Service_Branch 24 Status 126 Unit 128 Office_Symbol

It is important to note that I cannot join INSTRUCTORS and LIST_OPTION_ITEM, as there is no common column. However, LIST_OPTION_ITEM and LIST_OPTION_TYPE can join on OPTION_TYPE_ID. My desired output from a SELECT query:

Rank Specialty Duty Title Service Branch Status Unit Office Symbol CAPT CBRN TRAUMA NURSE IDMT-Squadron Medical Element 46N NURSE USA Guard CERFP

I've tried some solutions but can't come up with anything. Do I need a cross join or something? Help would be much appreciated.

I have a PyQt5 app. The app is bigger than the example which I am sharing now. I am sharing the following code for convenience.

Example application consisting of a GUI class, a FlaskAPI class, a class that provides a video stream. The GUI class uses the class that inherits QLabel class and called ImageLabel and this part is not related to my question. While displaying the video stream on the GUI, I want to enable a C# application to interact with my Python application. So I decided to use Flask to provide a REST interface for the C# application. However, I have a problem now. Because of the collision of the PyQt5 main thread and the FlaskAPI, I am trying to apply multithreading but I faced with a problem.

My problem is that I can't display GUI if I start FlaskAPI threading. How can I run the Flask API with GUI and communicate a method in GUI class?

I want to switch between cameras connected to the computer. I have PyQt5 list item and all cameras listed in there. So I also have camera indexes. However, I couldn't success switch between cameras interactively. When a new camera selected in the list I press the "REFRESH" button to display the selected camera stream on the PyQt label. How can I switch between cameras?

I use the following code to display stream and switch between them:

I'm new to the aggregate feature with mongodb and mongoose and have been having difficulty getting the desired results after passing data through my pipeline.

Below I have simplified the using a fictional example models

The scenario

I have 3 Models (Ship, Yatch, and Sailboat) that share the interface and extend from a base class. A 4th model, Captain, which has an array watercraftContexts that contain objects used to reference the types of watercrafts associated to each Captain.
