edit and use treeview cell
Friends, I am writing a gtk3(in C) code, that uses treeview. store = gtk_list_store_new (NUM_COLS, G_TYPE_STRING, G_TYPE_STRING, G_TYPE_STRING, G_TYPE_STRING, G_TYPE_STRING); tree = gtk_tree_view_new_with_model (GTK_TREE_MODEL (store)); cell = gtk_cell_renderer_text_new (); col_pub=gtk_tree_view_column_new_with_attributes ( Title, cell, text, COL_BIB_PUB, NULL); gtk_tree_view_column_set_sort_column_id( col_pub, ID_PUB); gtk_tree_view_append_column (GTK_TREE_VIEW (tree), col_pub); The problem is I want each cell of the treeview to be editable, so I need something like: g_object_set(cell, editable, TRUE, NULL); but I have no idea of how to connect the edited flag to file/buffer. It will be very helpful if someone kindly show the way...a very short example may be. Please help. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

i used something like that in gtk2 and it used to work,

Re: edit and use treeview cell
Thanks ZZ,
your code helped me making my code more general. Thanks a lot.
Now I can edit the cells well. But my final goal is to write them in a
file.
I will check a bit and come back if I need further help.

change treeview's cell height
Dear friends, How can I change cell (and hence row) height of a given row? In my treeview, I have cells of fixed width, and I want texts longer than that should be wrapped with height increased. Any solution anyone? ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

Get a pointer to the GtkCellRendererText for the column in question; depending on how you construct your TreeView there are different methods. When you have that you can experiment with changing different properties, such as wrap-mode and wrap-width.

Re: change treeview's cell height
Andrew, If I am not demanding to much, will you mind to have a look at the treeview defination that I posted? the problem is in treeview as written, store = gtk_list_store_new (NUM_COLS, G_TYPE_STRING, G_TYPE_STRING, G_TYPE_STRING, G_TYPE_STRING, G_TYPE_STRING); tree = gtk_tree_view_new_with_model (GTK_TREE_MODEL (store)); gtk_tree_view_set_rules_hint (GTK_TREE_VIEW(tree), TRUE); the rules_hint are not working, i.e. I am not getteing alternative color for each row.
