DCOP Widgets ideas

DCOPWidgets are widgets that are accessble via dcop. You can load a UI file that was built in designer and then access it from any lanuage that can talk via dcop.

User Interface File: The first step is to create a UI file for use with your program in Qt designer. Every widget you wish to access from dcop should have a name so KDE can build the interface for you.

Shell Script:
Next you write your script to manipulate the UI, and interact with your system. DCOPWidgets mapps most common Qt signals to events that you can handle from a case statement in the event loop.

#!/bin/bash
UI="file:///home/geiseri/dcopwidgets/src/test.ui"
WIDGET="Test"
ID=""
./dcopwidgets --name $WIDGET --file $UI | while read line
do
        case $line in
        exit.Released)
                dcop $ID $WIDGET exit
        ;;
        Starting.*)
                ID=`echo $line | awk -F. {'print $2'}`
        ;;
        go.Released)
                USER=`dcop $ID $WIDGET lineInput`
                proc=`ps -x -U $USER`
                dcop $ID $WIDGET setmlEdit "$proc"
        ;;
        MyChoice.Released.1)
                dcop $ID $WIDGET setlineInput "root"
        ;;
        MyChoice.Released.0)
                dcop $ID $WIDGET setlineInput "geiseri"
        ;;
        *)
        ;;
        esac
done

DCOPWidget in action:
Once it is all in place, run the script and the form comes to life. As you can see from the UI file above each Qt widget has a dcop interface so that you can manipulate it just like you can from C++.

This is only the crude begining. Im still adding more support for more widgets and building documentation. Stay tuned for more power from DCOP.
