OK, Here is the full guide with the final 2 steps included (update icon cache and uninstall). It is supposed to be step by step guide onhow to take a (simple) Qt app and package and deploy it with an Icon using Madde.

The project I have is simple, 1 window called mainwindow.

Note: As a convention I like to keep all my code together, so I have created any extra files in the "src" folder.

Steps:

1. Create project through Madde

2. Edit and test with QT Creator

3. Once ready to deploy create a clean empty top level folder "<projectname>-0.x" where x is your revision number e.g. "c:\Madde\0.5\home\shep\wwcalc-0.1"...In the OS
Note: the following 3 steps apply each time you go to build.

3.1 ensure there is no "debian" folder at the same level as "src"
3.2 ensure there is no folder structure called "<projectname>-0.x-orig" left over from a failed compile
3.3 remove old compiles from the Madde\home\user (e.g. C:\Madde\0.5\home\Shep) folder.

4. Copy the "src" folder from the tested Qt project into the "<projectname-0.x" folder

5. Create (or obtain) an application Icon. This should be a 64x64 png. Call it <projectname>.png and place it in the "src" folder.

6. Again inside the "src" folder create a new file called "<projectname>.desktop"

Code:

[Desktop Entry]
Encoding=UTF-8
Version=0.x
Type=Application
Name=<Long Descriptive Project Name>
Exec=/usr/bin/<projectname>
Icon=<projectname>
X-HildonDesk-ShowInToolbar=true
X-Osso-Type=application/x-executable

7. Again inside the "src" folder create a new file called "<projectname>.service" which looks like this

Code:

[D-BUS Service]
Name=org.maemo.<projectname>
Exec=/usr/bin/<projectname>

8. Inside the "src" folder added a file called "src.pro". Getting this right is the key to getting the Makefile correct and hence the install working. At the end of this file there is a section called "INSTALLS += "...for every file you want installed in a location you need an entry here. I've colour coded the 4 installs below for clarity.

Code:

TARGET = wwcalc
TEMPLATE = app
SOURCES += qtmain.cpp \
    mainwindow.cpp 
HEADERS += mainwindow.h 
FORMS += mainwindow.ui 
PREFIX = ../debian/wwcalc/usr

unix {
BINDIR = $$PREFIX/bin
DATADIR =$$PREFIX/share

DEFINES += DATADIR=\"$$DATADIR\" PKGDATADIR=\"$$PKGDATADIR\"

#MAKE INSTALL

INSTALLS += target desktop icon64 service

  target.path =$$BINDIR

  desktop.path = $$DATADIR/applications/hildon
  desktop.files += wwcalc.desktop

  icon64.path = $$DATADIR/icons/hicolor/64x64/apps
  icon64.files += wwcalc.png
  
  service.path = $$DATADIR/usr/share/dbus-1/services
  service.files += wwcalc.service

}

9. Up one level and inside the new top level folder (i.e. "c:\Madde\0.5\home\<YOU!>\<projectname>-0.x" ) created a file called "<projectname>.pro" with the following exact contents

Code:

TEMPLATE = subdirs
SUBDIRS  = src

10. In Madde make sure the runtime is up and connectible (described here) and then execute

Code:

mad dh_make --createorig --single -e foo.bar@gmail.com -c gpl

11. Step 10 creates a debian folder at the root level, Go there and edit the "postinst.ex" file

Code:

#!/bin/sh
# postinst script for <projectname>
#
# see: dh_installdeb(1)

gtk-update-icon-cache -f /usr/share/icons/hicolor

#maemo-select-menu-location <projectname>.desktop

exit 0

12. Again in Madde

Code:

mad qmake
mad dpkg-buildpackage
mad remote -r org.maemo.<projectname> send ../<packagename>_0.x-1_armel.deb
mad remote -r org.maemo.<projectname> install <projectname>_0.2-1_armel.deb

13. Uninstalling - from an X_Terminal

Code:

sudo gainroot
dpkg -r <projectname>

I hope this helps/works!

Many thanks to many users who helped me understand this structure especially too, Salser and danielwilms.
