1. EuGrid question
I've started using EuGrid, and I want to be able to wipe out an entire grid
(data and display). I'm displaying tables in a database, and the fields,
size of the tables change, so it's easier to simply delete and restart
whenever I want to display another table. There doesn't seem to be a good
way to do this. Here's what I've done:
-- wiping out a grid:
cols = EGW_EnumCols( grid )
for i = 1 to length(cols) do
void = EGW_DeleteCols( grid, cols[i] )
end for
void = EGW_LoadData( grid, {}, EGW_REPLACE )
The catch is, EGW_LoadData() doesn't like it when you send an empty
sequence, though this seems pretty obvious to me what should happen with
EGW_REPLACE, right? So, I added this elsif block to EGW_LoadData():
if grid > 0 and rows > 0 then
-- ... do lot's of stuff
elsif grid > 0 and insert_position = EGW_REPLACE then
-- data = {}, so delete the whole thing...
GridData[grid] = data
GridFlag[grid] = data
GridCurrentCell[grid] = {-1,-1}
end if
The only alternative to this seems to be to use EGW_DeleteDataRow(), which
would be severely inefficient. Of course, now I have a non-standard version
of EuGrid. :(
Is there a better way?
