kai mou bgazei to eksis error

 

Demo.java [72:1] incompatible types

found : java.awt.geom.Rectangle2D

required: java.awt.Rectangle

Rectangle b = GraphConstants.getBounds( attr );

^

Any help?

εισαι σιγουρος οτι αυτο σου βγαζει μονο..εκτος και μας διχνεις μερος του ολικου project καταρχην πρωτου φτασουμε στο προβλημα του τι γυρναει η

>
Rectangle b = GraphConstants.getBounds( attr ); 

 

οπου ειναι καθαρο το μυνημα οτι αλλο τυπο γυρναει η μεθοδος αλλο τυπος εχει γινει assign. H Rectangle ειναι υποκλαση της Rectangle2d ..(εχε το υποψιν σου)

 

 

ΑΛΛΑ!

>
private void adjustDisplaySettings( jg ) { 

 

αυτο δεν κανει compile ουτε του χρονου εκτος αν βαλεις και καποιο τυπο μπροστα..και υποψιαζομαι οτι αυτο ειναι το

JGraph ...με την βιβλιοθηκη του!

Javanidh, prospa8w na kanw kati me to jgraph kai den h8ela na mperdepsw kosmo ama eblepan ta import org.jgraph.JGraph kai diafora alla sxetika me to jgraph, ama 8es mporw na symperilabw kai tis ypoloipes grammes gia na boh8hsei sthn epilysh tou problhmatos.

 

Dokimasa kai me Rectangle2D alla tipota.

 

Me to jgraph kai thn biblio8hkh tou exeis asxolh8ei ka8olou?

Prepei na mhn exw kanei swsta to install tou, exw koita3ei oti exei gia download apo to site alla den ta exw kataferei akoma
