[Interest] how to debug a Qt Designer plugin

[Graham Labdon]

Hi
It was a missing path to dependant libraries

Thanks for the hint

Hi Graham,

It could be several things:

- the plugin has been compiled with debug - it must be release build.
- supporting DLLs are not available in your path.
- the code in the plugin is relying on initialisation that only occurs in your main exe.

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

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
