Re: [Java-gnome-developer] Using TreeView isgnals with Glade

[Khiraly <khi...@gm...>]

Finally I have a working code. But I have questions too.

Here is the example code:
-------------------- 
userlistTree = (TreeView) puliApp.getWidget("userlistTree"); // userlist tree
userlistTree.addListener(new TreeViewListener() {
	public void treeViewEvent(TreeViewEvent event) {
		 System.out.println("DoubleClick "+event);
	}
});
DataColumn[] dc = new DataColumn[3];
dc[0] = new DataColumnBoolean();
dc[1] = new DataColumnPixbuf();
dc[2] = new DataColumnString();
ListStore ls = new ListStore( dc  );
userlistTree.setModel( ls );
userlistTree.setHeadersVisible( false ); /* true by default */

TreeViewColumn col0 = new TreeViewColumn();
 CellRendererToggle render0 = new CellRendererToggle();
   col0.packStart(render0, true);
   col0.addAttributeMapping(render0,CellRendererToggle.Attribute.ACTIVE,(DataColumnBoolean)dc[0]);
 TreeViewColumn col1 = new TreeViewColumn();
 CellRendererPixbuf render1 = new CellRendererPixbuf();
   col0.packStart(render1, true);
   col0.addAttributeMapping(render1,CellRendererPixbuf.Attribute.PIXBUF,(DataColumnPixbuf)dc[1]);
 TreeViewColumn col2 = new TreeViewColumn();
 CellRendererText render2 = new CellRendererText();
   col0.packStart(render2, true);
   col0.addAttributeMapping(render2,CellRendererText.Attribute.TEXT,(DataColumnString)dc[2]);

userlistTree.appendColumn(col0);
userlistTree.appendColumn(col1);
userlistTree.appendColumn(col2);
		
TreeIter it = null;
boolean bool = true;

it = ls.appendRow();
ls.setValue(it, (DataColumnBoolean)dc[0], Boolean.valueOf( bool ).booleanValue() );

try {
	ls.setValue(it, (DataColumnPixbuf)dc[1], new Pixbuf("images/me.jpg") );
} catch(JGException e) { 
	System.err.println( "image not found : "+e.getMessage() );
}
ls.setValue(it, (DataColumnString)dc[2], "[HUN]Khiraly" ); 
------------------------------

My question is about the above code example is this three lines:
userlistTree.appendColumn(col0); 
userlistTree.appendColumn(col1);
userlistTree.appendColumn(col2);

All this three line generate an treeViewEvent(TreeViewEvent event) method call.
My program start to print three times the method's output:

DoubleClick org.gnu.gtk.event.TreeViewEvent[source=org.gnu.gtk.TreeView@17471e0,id=COLUMNS_CHANGED]
DoubleClick org.gnu.gtk.event.TreeViewEvent[source=org.gnu.gtk.TreeView@17471e0,id=COLUMNS_CHANGED]
DoubleClick org.gnu.gtk.event.TreeViewEvent[source=org.gnu.gtk.TreeView@17471e0,id=COLUMNS_CHANGED]

Of course, after if I double click on the item of treeview, It prints the above message.

Why userlistTree.appendColumn generates a doubleclick signal?
All the appendColumn will generate a doubleclick signal in the future?
