forked from openlp/openlp
Fixes bug #1405260 "Slide controller title forces window width to grow" and adds the functionality to elide the text in the label. The tool tip is set to the full text.
As bug #1390236 "OpenLP locks up / crashes when preforming a text search on bible" is caused by bug #1405260 "Slide controller title forces window width to grow" this has also been fixed. Also fixes a third bug which affects making selections with the keyboard when "single click to preview" is selected. Tests added for the new InfoLabel Class and for the bible media manager build_display_results method bzr-revno: 2466
