Hallo
ich bin blutiger anfänger in sachen java.
ich habe ein problem, ich habe ein Programm das umgeschrieben werden muß damit ich mit Konfabulator darauf zugreifen kann.
Im moment sieht das Programm so aus daß auf dem Schreibtisch ein normales Programmfenster geöffnet wird.
(unwissend nehme ich an daß das mit swing gemacht wird oder?)
Naja jedenfalls ist das ganze nicht schön anzusehen und ich schreibe gerade ein Widget mit dem ich auf dieses Programm zugreifen möchte.
Die Beschreibung des Java Programms:
es ist wie eine Fernbedienung aufgebaut hiermit kann ich Fernseher DVD usw bedienen. zu dem Programm gehört eine HardwarePlatine die via Bluetooth angesprochen wird und die wiederum das Ir Signal an den Fernseher schickt.
nun im Konfabulator Widget würde ich das gerne so lößen
<img>
<onMouseDown>
HIER MÜSSTE DANN DER BEFEHL STEHEN DER AN DIE JAVA APPLICATION GEHT
</onMouseDown>
</image>
Ich werde auch die codes der App mal posten:
BlueRemote.java
BlueRemote.mf
BtParms.java
coke-cd.xml
dvd.xml
Makefile
Monitor.java
RemotePanel.java
XMLFile.java
XYLayout.java
Ich steig da nich durch und da ich nicht die Zeit habe Java zu lernen villeicht kann mir einer von euch helfen mein Problem zu lößen!?

}Ich steig da nich durch und da ich nicht die Zeit habe Java zu lernen villeicht kann mir einer von euch helfen mein Problem zu lößen!?
