Because of the first point, you can't run Designer and debug the plugin. Also note that a single plugin can contain all of your widgets, you don't need a separate plugin for each. See QDesignerCustomWidgetCollectionInterface. Hope that helps, Tony From: interest-bounces+tony=rightsoft.com...@qt-project.org<mailto:interest-bounces+tony=rightsoft.com...@qt-project.org> [mailto:interest-bounces+tony=rightsoft.com...@qt-project.org] On Behalf Of Graham Labdon Sent: Thursday, 11 December 2014 3:28 AM To: Interest@qt-project.org<mailto:Interest@qt-project.org> Subject: [Interest] how to debug a Qt Designer plugin Hi I have developed some designer plugins that are working nicely. Now I have created another but cannot get it to work. Within designer I see the following when I do Help->about Plugins - Failed Plugins C:\Qt\Qt5.3.0\5.3\msvc2012_opengl\plugins\designer\QtDesignerWidgets.dll Cannot load library C:\Qt\Qt5.3.0\5.3\msvc2012_opengl\plugins\designer\QtDesignerWidgets.dll The specified module could not be found Can anyone give me some idea as to how to debug this thanks
