An Extension Dialog Example

+ + + +

This example demonstrates how to create an extension dialog. +

Essentially all that is necessary is to create a standard dialog +and then create a QWidget form to be used as the extension. See +the article in Qt + Quarterly issue #3. +

Project file: +

TEMPLATE        = app
+LANGUAGE        = C++
+
+CONFIG          += qt warn_on release
+
+REQUIRES        = full-config nocrosscompiler
+
+SOURCES         += main.cpp
+FORMS           = mainform.ui \
+                  dialogform.ui \
+                  extension.ui
+DBFILE          = extension.db
+
