From: Bowon Ryu Date: Wed, 10 Jul 2024 05:38:23 +0000 (+0900) Subject: Add RequestAsyncRenderWithConstraint to text label X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a7cb948e46e3531a1bf12bb681c0d2dc595b5183;p=platform%2Fcore%2Fuifw%2Fdali-toolkit.git Add RequestAsyncRenderWithConstraint to text label Requests asynchronous rendering with the maximum available width using the given widthConstraint. If the width of the text content is smaller than the widthConstraint, the width will be determined by the width of the text. If the width of the text content is larger than the widthConstraint, the width will be determined by the widthConstraint. The height is determined by the content of the text when rendered with the given width. In this case, the result will be the same as the height returned by GetHeightForWidth.
