* Add card completion popups to chats and search fields Completes @mention and [[card]] in chat, and card names in the deck editor, EDHREC, Archidekt, card art rules, and user card settings searches. Pops up a styled list with mana pips and a card image preview, flipping the list order when the popup opens above the text field. --------- Co-authored-by: Lukas Brübach <Bruebach.Lukas@bdosecurity.de>

|
|
*
|
|
* The original row order is kept intact in the source model (row 0 is always the
|
|
* closest match). When enabled, the proxy maps the source rows in reverse so the
|
|
* popup shows the closest match in the row nearest to the text edit. Any change
|
|
* in the source model is forwarded as a full reset, which is all QCompleter
|
|
* needs to rebuild its completion list.
