"inherit qt4e" is enough, no need to add qt4-embedded to DEPENDS.

strange, demos and examples are packaged in ${QT_BASE_NAME}-demos and
${QT_BASE_NAME}-examples packages so if you find these directories on
your target, that means you requested qt4-embedded-demos and
qt4-embedded-examples to be installed in your image.
Are you installing packagegroup-core-qt4e in your image like in
qt4e-demo-image ? If yes, that's where you pull demos & examples.
To get a minimal image, you could simply have :
IMAGE_INSTALL += "\
${CORE_IMAGE_BASE_INSTALL} \
you_qt_app \
some qt4-embedded-fonts or qt4-embedded-plugin you may need
(check packagegroup-core-qt4e.bb for the exact names) \
"
inherit core-image
The Qt libraries your application is linked with will be automatically
installed and you won't get extra unwanted packages in your image.
Best regards,
Eric
