[GRASS-dev] question about potential enhancements to dbms

Martin,

I’ve been trying out your updates to the dbms module and fixing little odds and end. This is a fantastic tool. The ability to highlight vector features is really nice. I had a couple ideas for enhancements but wanted to run them by you before doing anything, since I don’t want to mess up any plans you already have.

  1. What about adding a “display selection” button? Currently, you need to double click a record for it to highlight (AFAICT). This is easy for a single record, but trickier for multiple selections. A “display selection” button would make this easier. It could also make it easy to display the results of an SQL selection.

  2. How about an “extract to new vector” button? This would take the current selection and run v.extract to create a new vector based on your sql or interactive selection.

Finally, I have a question (actually a group of questions). I can easily edit the first record in the browse list control, but can’t edit any other ones. Is this a setting? A bug? Is a button needed to turn on editing? Could it be with double clicks if we have a display selection button?

Also, there is a bug in an editable list control that I’ve reported and I’m wondering if you have it with Linux too. I can edit any field that is showing completely in the window, without scrolling to the right. If you have to scroll right to the field, and double click to edit it, it will edit some field to the left instead of the field you intended to edit. It shows up for me in the wxPython demo as well as in the dbms table.

1) What about adding a "display selection" button? Currently, you need to
double click a record for it to highlight (AFAICT). This is easy for a
single record, but trickier for multiple selections. A "display selection"
button would make this easier. It could also make it easy to display the
results of an SQL selection.

Highlighting selected features is accessible also from the contextual
menu. Select item(s), right click, "Display selected". I will add also
"Display all" (for SQL selection).

2) How about an "extract to new vector" button? This would take the current
selection and run v.extract to create a new vector based on your sql or
interactive selection.

Good idea. I can see you have already implemented this functionality. Great.

Finally, I have a question (actually a group of questions). I can easily
edit the first record in the browse list control, but can't edit any other
ones. Is this a setting? A bug? Is a button needed to turn on editing? Could
it be with double clicks if we have a display selection button?

Only first? Select item, right click, "Edit selected record". Seems to
work for me.

Also, there is a bug in an editable list control that I've reported and I'm
wondering if you have it with Linux too. I can edit any field that is
showing completely in the window, without scrolling to the right. If you
have to scroll right to the field, and double click to edit it, it will edit
some field to the left instead of the field you intended to edit. It shows
up for me in the wxPython demo as well as in the dbms table.

It was bug I just forgot to comment listmix.TextEditMixin for virtual
list. You can edit records from contextual menu ("Edit selected
record").
