I have creating this treetable
Now I want to sum up th children values and show the result in the parent cell under the related column. For example for Function 7 in column 2 and row 2 I want to right 2.0, and for Function 11 column 4 row 4 right 1.0 (function 12 + function 13)
Here is the code which produces the treetable.
root.setExpanded(true);
Set<String> combinedKeys = new HashSet<>(dc.getCombiFunc().keySet());
Set<String> funcAllKeys = new HashSet<>(dc.getSortedfuncAll().keySet());
funcAllKeys.removeAll(dc.getCombiFunc().keySet());
for (List<String> value : dc.getCombiFunc().values()) {
funcAllKeys.removeAll(value);
}
for (String valueremained : funcAllKeys) {
ArrayList<String> tempNameId = new ArrayList<>();
tempNameId.add(dc.getSortedfuncAll().get(valueremained));
// all elements which are not in combined functions (They are all
// orphan)
root.getChildren().add(new TreeItem<String>(tempNameId.get(0)));
}
// Getting Keys that have children//////
Set<String> keyFromcombined = new HashSet<>();
List<String> valueOfCombined = new ArrayList<String>();
for (Entry<String, List<String>> ent : dc.getCombiFunc().entrySet()) {
for (int i = 0; i < ent.getValue().size(); i++)
valueOfCombined.add(ent.getValue().get(i));
}
List<String> rootKeyList = new ArrayList<>();
for (String key : combinedKeys) {
if (!valueOfCombined.contains((key))) {
keyFromcombined.add(dc.getFuncAll().get(key));
rootKeyList.add(key);
}
}
String[] rootKeys = rootKeyList.toArray(new String[rootKeyList.size()]);
// ////////////////treetable////////////////////////////
treeTable.setRoot(root);

TreeMap temp clones dc.getFuncTypeOrg(). In this TreeMap I have value for each child (color and the number). then in cellfactory i multiply value in color ( green = 1 and yellow = 0). Outside the loop I thought to make a treemap containg each parent as key and all it's children as value. Then I can sum up children values together and make a treemap in which first key is parent and as value the required value(or just string ArrayList ). After that I can check the name of cell in cellFactory and if it is a parent just right the value in the cell. I have been told how i can get treeitem values, and i am now here :
//after col loop ends
TreeMap<String, List<TreeItem<String>>> mytreemap = new TreeMap<>();
TreeMap<String, List<String>> parChild = new TreeMap<>();
for(TreeItem node: root.getChildren()){
if(!node.isLeaf())
mytreemap.put(node.getValue().toString(), node.getChildren());
}
for(Entry<String, List<TreeItem<String>>> ent: mytreemap.entrySet()){
for(TreeItem myItem : ent.getValue()){
// how can i fill parChild with parent as key and all its children as value?
System.out.println(ent.getKey()+" "+myItem.getValue());
}
}
treeTable.setPrefWidth(1200);
treeTable.setPrefHeight(500);
treeTable.setShowRoot(false);
treeTable.setTableMenuButtonVisible(true);
return treeTable; }
Here at setCellFactory
else if (item.contains("parent")) {
for (int i = 0; i < dc.getFuncTypeOrg().size(); i++) {
}
i can get the roots. Is there a way to do a recursion (up to the number of children and subchildren for that root cell) and add their value together and setText the parent cell to that value?
