GTK4: Finding a row/data on GtkColumnView

[Osmo_Antero]

Hello,
I have two (2) questions about the GtkColumnView on GTK4.

Question 1:
How do I find the data/row when right-clicking on the GtkColumnView listing?
Meaning, how do I find the clicked GListStore item at mouse (x, y) position?

My example program creates a popup-menu at the right-click (x,y) location, but I cannot find the corresponding GtkColumnView data. I want to delete the row and data.
See the example code (colview1.c).

Notice:
In GtkTreeView widget on GTK3/GTK4 I can find the clicked GtkTreePath with these lines:
gtk_tree_view_convert_widget_to_bin_window_coords(tv, … x, y, …&xx, &yy…)
gtk_tree_view_get_path_at_pos(tv, xx, yy…)

But the new GtkColumnView widget has no equivalent option, or does it have?

Question 2:
Problem with sorting when clicking on the headers (GtklColumnView).
My example program (colview1.c) has column headers, but the code does not sort data when clicked on the column-header. It displays and changes a small arrow on the headers, but does no sorting.
I have added my own sort-function on column headers !
Why does’t it work?
See the example code (colview1.c).

The code colview1.c:

colview1.c

Compile it by:
gcc pkg-config --cflags gtk4 -lm -o colview1 colview1.c pkg-config --libs gtk4

( It shows directory listing of the current directory. Copy some files into it.)
Run it:
./colview1

Hello,

GtkColumnView:
I found a GRAZY way to find the clicked row.
I do not mean the selected row here. I mean the RIGHT-MOUSE clicked row. That is a different thing.

I find the position (clicked row and item) by counting Widget heights and Y-positions.
LOOL, I MUST BE GRAZY … OR THIS TOOL-KIT IS IT. SURELY IT IS !

    static void button_pressed_cb(GtkGestureClick *gesture, gint n_press, gdouble x, gdouble y, MainData *main) {
    	GtkWidget *colview = gtk_event_controller_get_widget(GTK_EVENT_CONTROLLER(gesture));
    	const gchar *colview_type_s = G_OBJECT_TYPE_NAME(colview);

    	if (strcmp(colview_type_s, "GtkColumnView") != 0) return;

    	gint line_no = -1;

    	GtkWidget *child = gtk_widget_get_first_child(colview);
    	GtkAllocation header_alloc = {0, 0, 0, 0};
    	while (GTK_IS_WIDGET(child)) {

    		if (strcmp(G_OBJECT_TYPE_NAME(child), "GtkListItemWidget") == 0) { 
    			gtk_widget_get_allocation(child, &header_alloc);
    		}	

    		//if (G_OBJECT_TYPE(child) == GTK_TYPE_COLUMN_LIST_VIEW) {
    		if (strcmp(G_OBJECT_TYPE_NAME(child), "GtkColumnListView") == 0) { 
    			line_no = check_list_widgets(child, y, header_alloc.y + header_alloc.height);

    			// Break out the loop
    			break;
    		}

    		child = gtk_widget_get_next_sibling(child);
    	}

    	if (line_no > -1) {
    		GFileInfo *finfo = g_list_model_get_item(G_LIST_MODEL(gtk_column_view_get_model(colview)), line_no);
    		if (!G_IS_FILE_INFO(finfo)) {
    			g_warning("Cannot read GFileInfo at row #%d\n", line_no);
    			return;
    		}

    		const gchar *name = g_file_info_get_name(finfo);	
    		
    		g_print("You clicked on %s\n", name);
    		
    		g_object_unref(finfo);

    	}	
    }

And the function:

gint check_list_widgets(GtkWidget *w, gint y, gint header_height) {

	GtkWidget *child = gtk_widget_get_first_child(w);
	gint line_no = -1; 

	gint curr_y = header_height; 
	
	while (GTK_IS_WIDGET(child)) {
		//if (G_OBJECT_TYPE(child) ==  == GTK_TYPE_LIST_ITEM_WIDGET)
		if (strcmp(G_OBJECT_TYPE_NAME(child), "GtkListItemWidget") == 0) { 
			line_no++;

			GtkAllocation alloc;
			gtk_widget_get_allocation(child, &alloc);

			if (y > curr_y && y <= header_height + alloc.height + alloc.y ) {
				return line_no;
			}
			
			curr_y = header_height + alloc.height + alloc.y;
			
		}

		child = gtk_widget_get_next_sibling(child);
	}
	return -1;
}
