Subject: Allow configuring the resizing mode for StyledLabel
X-Git-Tag: 0.5-rc2~82
X-Git-Url: https://git.quassel-irc.org/?p=quassel.git;a=commitdiff_plain;h=67a12e19088282f2218b602463cae3de5bb5baad

Allow configuring the resizing mode for StyledLabel

We now allow either no auto-resize (e.g., always one line with tooltip), always adjust
to contents, or resize only on mouse hover.
