category selection control

[Sorcerer]

Is there any method that can be used to count the number of categories present in a windowlist?

I would like to be able to resize the window so that all category tabs are always displayed when the containing window is opened - currently it is not always obvious that there are extra tabs that are hidden off the edge of the window.

How about looping through the database nodes using ipairs and count/comparing the category nodes e.g.



local count = 0;
for k,v in pairs (getDatabaseNode().getChildren()) do
if v.getName() == "category" then
count = count + 1;
end
end

Hi DrZ thanks for the reply.

I tried something similar before, but it appears category nodes are not counted as children. The above would return 0

if you do something like print(DB.findNode("encounter").getChildCount())
the number returned matches the number of encounters the categories appear to be ignored.

Hmm, not sure then. I guess you would have to request an API change. i.e. something like access methods for windowlists like

- getCategories() returns a table of strings
- getCategoryCount() returns integer count of categories

Yeah thats what I figured, but I think M_W probably has enough on his plate without working on something with such limited use.

I just wondered if anyone had found a workaround.
Its not really a big issue.

anyway thanks for your help.
