[Gretl-devel] tooltip for right-clicking variables in model chooser

Hi, related to a request for more intuitive variable selection (https://sourceforge.net/p/gretl/feature-requests/211/) we talked about adding a tooltip that informs users that you can do a right-click on a listed variable (e.g., in the OLS model spec dialog). I looked at the code and found a kind of similar example related to the Midas dialog, in gui/selector.c. In the function <static GtkWidget *var_list_box_new> there is the statement:  if (locus == SR_RVARS2 && sr->ci == MIDASREG) {         gretl_tooltips_add(view, _("Select and right-click to edit specification")); Obviously, we need a different "locus" for our purpose, and we don't want to be restricted to midas; so how about adding the following to an already existing if-block in the mentioned function: if (locus == SR_LVARS) {     /* left-hand box with the selectable vars */   ... other instructions...     gretl_tooltips_add(view, _("Select and right-click to add to regressor list")); } ... Would that already do the trick? thanks sven
