Branch: refs/heads/master Author: Colomban Wendling <ban(a)herbesfolles.org> Committer: Colomban Wendling <ban(a)herbesfolles.org> Date: Sat, 13 Apr 2024 23:58:17 UTC Commit: 3bc2cf5efb0e6d71dccc88105658656e70282a61 https://github.com/geany/geany/commit/3bc2cf5efb0e6d71dccc88105658656e70282… Log Message: ----------- Fix search entry after editing the toolbar According to b0b0ebb469a6b7eb74d321e6f5d7fe6f0bfcf6ba we guard against proxying the widget more than once for some Windows reasons, but this breaks the case where the same GeanyEntryAction has to re-create a fresh proxy, like when moving the item around. So, move the guard value to the proxied widget, not the action. Fixes #3831.
