Hi Igor, you actually need to fetch existing columns from the tree view one by one, until you find a match, something like the code below. Regards, Miroslav int current = 0; GtkTreeViewColumn *cur_column = gtk_tree_view_get_column ( while (cur_column != NULL) { if (clicked_column == cur_column) { break; //found it } current ++; cur_column = gtk_tree_view_get_column ( } if (cur_column != NULL) { // found the matching column, index stored in "current" } On 10/9/2018 3:00 AM, Igor Korot via gtk-list wrote: Hi, list, Does anybody know how do I get the information?

Maybe the thing to do is write a bit of code and see what happens--I've never needed to to know the column number.

But that's wrong, because folder1 is at row 2 column 2. By extension, folder5 would be indices[1,2,0] and folder6 [1, 2, 1] And folder5 should be at row 8 column 3. And what is the coordinate be for disk1? It should be row 1, column 1, right? So as you can see I'm trying to get a value of the column number. On top of that I will need to get a column 1 if I click where the "X" is on the diagram... Thank you. On 08/10/2018 18:25, Igor Korot wrote: Ok. Now let's get back.

Actually, my daughter speaks pretty good Russian--she was a competitive figure skater for a lot of years and both her principal coaches were Russian. The preferred Russian over English so my daughter learned Russian. Anyway, she translated the songs years ago just to practise.

No. They're from a recording made in London in about 1959. Once upon a time, back in the 60s, I had an LP version that had some translations printed on the liner, but that LP vanished decades ago. Other than Tipperary, Annie Laurie, and Oh no, John!, they're in Russian. I understand. And that's why I offer to translate them to English if you are interested. Thank you.

(You can get the depth of the tree--thus the number of entries in the vector--with: gint len = gtk_tree_path_get_depth (path); ) If it's a simple two-dimensional tree, the column number will be indices[1], but you might want to make sure that the tree depth is at least two before doing that or you might be pointing past the end of the indices array. BTW, what do you mean by saying: "simple 2-dimensional tree"? Is there going to be n-dimensional tree? How it will be represented on the screen? Do you have a screenshot? Thank you. By the way, don't try to free the indices array--it points to a GTK internal structure.

That function receives as a parameter column the GtkTreeViewColumn in which the activation occurred. The problem is (at least as I see it) is that it is not a simple integer for the column number. Is there a simple way to get a column number on which I activated the row from this signal?
