The program outputs the following warnings: umbrello(9216)/kdeui (kdelibs): Attempt to use QAction "edit_undo" with KXMLGUIFactory! umbrello(9216)/kdeui (kdelibs): Attempt to use QAction "edit_redo" with KXMLGUIFactory! umbrello(9216) *UMLListView::findView: could not find "class diagram" in UMLListViewItem: "Logical View", type="lvt_Logical_View", id="Logical View", children=1 umbrello(9216) *UMLListView::findView: could not find "class diagram" in UMLListViewItem: "Logical View", type="lvt_Logical_View", id="Logical View", children=1 Trying to open a new window with the "File -> New..." menu outputs again the two last lines of the output (could not find "class diagram") Reproducible: Always Steps to Reproduce: 1.

Unfortunately, this does not change anything to the described behaviour. 1425847 3 celak.pande 2014-01-20 05:22:23 +0000 I am also affected by this bug on Archlinux Linux Qt: 4.8.5 KDE Development Platform: 4.12.1 Umbrello UML Modeller: 2.12.1 1426466 4 celak.pande 2014-01-23 13:40:32 +0000 This would probably solves this problem, apparently umbrello main window started with 0 width and height. So I added this parameter in umbrellorc [General Options] Geometry=800,600 https://bbs.archlinux.org/viewtopic.php?pid=1369652 1426498 5 nicos 2014-01-23 16:22:49 +0000 Great, I can confirm that changing these settings also solve the issue for me. To my understanding, the function: UmbrelloSettings::geometry() returns (-1, -1) as a size if no proper umbrellorc is present, and the values are returned/used without being checked. 1427193 6 ralf.habacker 2014-01-27 15:00:32 +0000 (In reply to comment #5) > Great, I can confirm that changing these settings also solve the issue for > me.

According to https://qt-project.org/doc/qt-4.8/qwidget.html#minimumSize-prop are these values checked against minimumSize(). On my development machine minimumSize() returns QSize(0, 0), before the call to resize() , which means resize will set the size to (0,0). The mentioned documentation says about this case: "Note: Setting the size to QSize(0, 0) will cause the widget to not appear on screen. This also applies to windows." 1427280 7 okellogg 2014-01-27 22:01:27 +0000 (In reply to comment #5) > Great, I can confirm that changing these settings also solve the issue for > me. To my understanding, the function: > UmbrelloSettings::geometry() > returns (-1, -1) as a size if no proper umbrellorc is present, and the > values are returned/used without being checked. Looking at the code, it seems the values are really being used without being checked. See UMLApp::readOptions() in umbrello/uml.cpp:1022 resize(UmbrelloSettings::geometry()); When UmbrelloSettings::geometry() returns unexpected values such as (0,0) we should perhaps fall back to some sensible values? 1427840 8 ralf.habacker 2014-01-30 14:01:36 +0000 Git commit c6640aa458af39b1a31fb04ae6de26f0084f7758 by Ralf Habacker.
