Change expand and collapse image TreeView JavaFX 2.2

expand, image, java, javafx-2, treeviewitem

Solution

Sure, this is possible with a little bit of css. The CSS looks like this:

.tree-cell .tree-disclosure-node .arrow {
    -fx-shape: null;
    -fx-background-color: null;
    -fx-background-image: url("plus-arrow.png");
}
.tree-cell:expanded .tree-disclosure-node .arrow {
    -fx-shape: null;
    -fx-background-color: null;
    -fx-background-image: url("minus-arrow.png");
}
