Clip and ellipsize GTK labels - #4451
Merged
Merged
Conversation
Fixes beeware#3780. GTK labels are not clipped to their bounds; there is a native ellipsize option on the widget we should enable to automatically put ellipsis at the end of the text if necessary. Enabling this changes the way we use native functions to rehint, and the rehint code is modified accordingly. We should still clip the widget to bounds, however, because the user may set a very very tiny label that can't even fit a single ellipsis, but still we have to clip the label properly to avoid overflow. A drive-by fix to the example app involves bumping the width for the button box, as the buttons were hinted to >120px wide and was overlapping with the text.

FWIW: I wasn't being very careful with PR management, and it turns out that with the current timeline, I'm exceeding the 2 PRs for review expectation. Drafting this again... |

There was a problem hiding this comment.
Nice work. I've made a slight tweak to the example so that it's more clear when truncation isn't working; but otherwise, this is a nice improvement.
