[Qgis-user] QCompleter in QGIS form

[Blumentrath, Stefan]

Hi again,

Now I spend some more thoughts on 2) and consider to write a Python macro for project start, which runs the query and writes results (completer items) kind of hard-coded into the form init function (meaning I will have to have a template for the form init function, which then is saved with the final name (overwriting earlier versions), while completer items are being injected).

Do you think such a solution will cause the form to open faster (depending on the connection speed to the data base probably)? Or is it almost equally costly to load a rather long init-function (python script text fie)?

Cheers,
Stefan

P.S.: Esp. help on 1) is still most welcome...

P.P.S.: If it is of interest for others I could publish / document my QCompleter solution on github...

>Yet there are two things I am struggling with:

Would it be possible to avoid this, I >mean that the query is only run once (e.g. when I open the project)? I hoped this could speed up the start of the form (even if the query gets cached in >PostgreSQL)...
