Created attachment 97866 [details] signed-testcase-for-stretches.eml I've been getting this for "quite long", but I suspect that it's been mostly on the gpg branch, but definitely prior to the massive change to MessageView [1]. Opening a certain message leads to a rendering where the enclosed widget has height() == 0px, as confirmed by GammaRay. [1] https://gerrit.vesnicky.cesnet.cz/r/660
Created attachment 97867 [details] initial rendering -- see that nothing is really shown
Created attachment 97868 [details] After pressing the "show details", the view expands a bit
Created attachment 97869 [details] After manually resizing the area which is for the whole MessageWidget's height Also, I can select by mouse within the too-small part widget, and the text scrolls. This picture shows the end result of that after I forced it to redraw by resizing the MessageWidget's area. Thomas, patches or suggestions are welcome :). Preferably on top of https://gerrit.vesnicky.cesnet.cz/r/660 .
Git commit f90a8ff7c25ea2825c3d2cb714ba6843058f2793 by Thomas Lübking. Committed on 13/03/2016 at 22:52. Pushed by gerrit into branch 'master'. show widget after reparenting it ::addingOneWidget creates an unparented or foreign widget, QLayout::addWidget() will implicitly reparent it to the layouts parenting widget and reparenting widgets implicitly hides them (don't ask - it's always been like that) ::adjustSize() simply skips hidden children and whatever finally shows the widget does not activate the layout Change-Id: Ia7f7af4efd2c631bb3a5a9c0ad7f8e67d426138f M +1 -0 src/Gui/PartWidget.cpp http://commits.kde.org/trojita/f90a8ff7c25ea2825c3d2cb714ba6843058f2793
