Subject: Auto-crop notification message in case it's longer than the window
X-Git-Tag: lulzbot-17.11~2
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?a=commitdiff_plain;h=5e459bf9f762ddb3618ea07e2844ee0d05047aaf;p=cura.git

Auto-crop notification message in case it's longer than the window

If the scene view is smaller than required for the notification message
we must crop the text and add elipsis to it so it fits, otherwise,
the message will simply disappear.
Fixes T254
