egui | Educational GUI library for Linux on embedded devices

I am using ag-Grid to create a grid within a grid using a cell renderer. This is the code for the cell renderer.

I have a Master-Detail ag-grid. One column has checkboxes, (checkboxSelection: true). The details grid have a custom status panel with a button. When the user clicks the button in any specific Detail grid, I don't know how to get the SelectedRows from just that one specific detail grid.

The problem is they might leave multiple details displayed/open, and then looping over each Detail Grid will include results from all open grids. I'm trying to isolate to just the grid where the user clicked the button.

I tried looping through all displayed/open detail grids to get the Detail grid ID. But I don't see any info in this that shows me which one they clicked the button in.

I tried in the button component to see if, in the params, there is anything referencing the detailgrid ID that the button is in, but I did not see anything there either.

This is the button component:

I previously upgraded my AG Grid package from an 18x to 20.0.0 (Community Version). In the previous version, I was simply able to pass an HTML string to the colDefs.headerName property and it would render HTML in the header.

This new version renders header and cell data as a string by default. So now the column headers are rendering like this:

I am a system administrator of a server/client environment that doesn't have SCCM and I want to check if computers in my organization have a file name using a batch file.

I want the script to check if the file egui.exe is in one of these directories:

I've written a code that terminates egui.exe. But my callback function doesn't run after the WM_CLOSE message is processed. Why?

I'm trying to build (in Windows) with GCC 4.9.2 the eGUI library by John Torjo, removing every dependence from boost.
In several files I find this typedef: typedef std::function1 func;
Compiling, I get the following error:
.. \ .. \ Egui \ core \ detail \ event_handler.hpp | 44 | error: 'function1' in namespace 'std' does not name a template type |
The boost documentation defines the Class template FunctionN: boost::FunctionN - A set of generalized function pointers That can be used for callbacks or wrapping function objects. Now, I ask: boost::function1 may be replaced by some standard class? In I don't seem to find anything that might serve the purpose.

I'm replicating the ag-grid Viewport example putting it in an object representing the table instead of a anonymous function. I cannot understand why it gives me the error in the title when trying to connect to the mockserver, given that it is exactly the same code.

Here it is the code that doesn't seem to work:
