From 4a13dbe3bb22ba47cf1ea5dfe0e9ffc9688b048a Mon Sep 17 00:00:00 2001 From: flow Date: Thu, 14 Jul 2022 22:23:41 -0300 Subject: feat: create delegate for project item views This allows us to define custom painting for list view items. In particular, this is applied to the mod downloader, in order to allow displaying both the mod name and mod description, and settings their effects (like bold or underline) independent of each other.
