Hi Dvora,
the open/close icons in a tree are part of its appearance theme. You can
change them by modifying "Appearance.js" in your application's "theme"
subfolder. E.g.:
qx.Theme.define("myApplication.theme.Appearance",
{
extend : qx.theme.modern.Appearance,
appearances :
{
"tree-item/open" :
{
include : "image",
style : function(states)
{
var icon;
if (states.selected && states.opened)
{
icon = "path/to/my-open-selected.png";
}
else if (states.selected && !states.opened)
{
icon = "path/to/my-closed-selected.png";
}
else if (states.opened)
{
icon = "path/to/my-open.png";
}
else
{
icon = "path/to/my-closed.png";
}
return {
padding : [0, 5, 0, 2],
source : icon
};
}
},
}
}
I hope this helps. Additionally, you should pay some attention to [1]
and [2].
Cheers,
Norbert

Hi,
In the demobrowser, under widget - Tree, the Desktop TreeFolder has 2
icons showing.
One is a triangle (facing down or to the right, depending if folder is
open or closed) and the second is user-desktop.png.
The latter appears because of the setIcon statement.
Could somebody please explain to me how the triangle appears?
I have used setIcon and setIconOpened statements - which allows one or
the other icon, but never two icons.
Thanks in advance!
Dvora
