I am new in QGIS plugin development using Python and Qt designer. Previously, I did lot of AddIns development for ArcMap using C#. I am using Plugin builder to develop the plugin.
Is there any way I can create a basic 'Hello World' plugin using windows form not the dialog with button template provided by the plugin builder?
QMainWindow
instead of a dialog or dockwidget. You could try installing this and have a look at the source code =)
