Subject: Extract function to grab buttons when managing a window.
X-Git-Tag: 4.12~103^2~1
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=66882bf445970588c6c7a6a2c2e08a38ad0b9536;p=i3%2Fi3

Extract function to grab buttons when managing a window.

We refactor the button grabbing into a function to allow the next patch
both to
  - conditionally grab different sets of buttons
  - grab the buttons again when reloading the config.

relates to #2049
