qmap | Goals Updates in Reinforcement Learning Using Convolutional | Machine Learning library

I have huge data that consist of points(x,y) and need to present in a scatter plot.

To find overlap and remove invisible differences between the same point, I wrote bellow code :

I try to define a QMap which it's key is a C++ structure.

for a project I need to integrate a lot of data in a QListView, I get the data from a QThread and store it in a QMap, until then I have no problem of crash or freeze. But when in my QThread I browse my QMap to call for each element the function that will add the QString in the QListView, then I have a freeze. I searched a lot but I didn't find or understand how to do it. I add you a part of the simplified code to show you my problem :

exemple.h

My Compressor class has field QMap &> *techniques; and static method static DataList & sndStep(DataList &l);. Their type definitions:

This is a simplified working representation of my code. I have two collections of locations of points. One is automobiles and the other is dealers. There is a slider of distance in miles. If a user clicks on the dealer location and selects the distance on the slider, only the auto locations within the distance from the dealer selected will be visible on the map. I have a another picklist of city which works well. However, when I pick a dealer the display goes to an error and I get Warning: Error in .pointsToMatrix: points should be vectors of length 2, matrices with 2 columns, or inheriting from a SpatialPoints object* I have looked at some other questiosn with the same error bu they are very different problems. Thanks in advance !

I have made a very simplified version of a problem I had asked two days ago in another post (Getting Leaflet to work with Datatable selection in R shiny) and I am much closer to a solution. There is an R dataframe with 12 locations in 4 cities in MA. The dataTable lets the user select the City and the leaflet map will only display the locations in the City chosen.

I've used an example code (source: https://forum.qt.io/topic/11390/increasing-contrast-of-qimage/4) to change contrast of a QImage (I've also edited it a little) :

I have a UI with dynamically created Custom widgets. Each custom widget has 2 QLineEdits from which user input has to be parsed.

Information from a each one of these Custom Widgets through its 2 QLineEdits has to be read and processed within my application. Each CustomWidget directs one specific action of a machine for a determined period of time, so I'm trying to get a "todo list" for my machine like so:

On a subclassed QListWidget I have several items. Every QListWidget item (e.g. "ROS Init", "Images" etc) that is shown below is associated with a specific icon.

The problem I have is that I am trying to drag and drop the specific icon corresponding to that QListWidget item, but nothing happens.

Below the function responsible for the dragging:
