See also IupImage. If node is a branch it is used when collapsed. All images do NOT need to have the same size, but it is recommended that a branch expanded and collapse images to have the same size.
IMAGEEXPANDEDid (write only): same as the IMAGE attribute but used for expanded branches.
IMAGELEAF: the image name that will be shown for all leaves. Default: "IMGLEAF" (a bullet). Internal values "IMGBLANK" (blank sheet of paper) and "IMGPAPER" (written sheet of paper) are also available. If BGCOLOR is set the image is automatically updated.

VALUE (non inheritable): The focus node identifier. When retrieved but there isn't a node with focus it returns 0 if there are any nodes, and returns -1 if there are no nodes. When changed and MARKMODE=SINGLE the node is also selected. The tree is always scrolled so the node becomes visible. Additionally accepts the values:
"ROOT" or "FIRST": the first node (which is always expanded)
"LAST": the last expanded node
"NEXT": the next expanded node, one node after the focus node. If at the last does nothing
"PREVIOUS": the previous expanded node, one node before the focus node. If at the first does nothing
"PGDN": the next expanded node, ten nodes node after the focus node. If at the last does nothing
"PGUP": the previous expanded node, ten nodes before the focus node. If at the first does nothing
"CLEAR": clears the selection of the focus node.
CANFOCUS (creation only) (non inheritable): enables the focus traversal of the control. Default: YES.
PROPAGATEFOCUS(non inheritable): enables the focus callback forwarding to the next native parent with FOCUS_CB defined. Default: NO.
FOCUSFEEDBACK (non inheritable): draw the focus feedback. Can be Yes or No. Default: Yes.
HASFOCUS (read-only): returns the button state if has focus. Can be Yes or No.
MARK (write only) (non inheritable): Selects a range of nodes in the format "start-end" (%d-%d). Allowed only when MARKMODE=MULTIPLE. Also accepts the values:
"INVERTid": Inverts the specified node selected state, where id is the specified node identifier. If id is empty or invalid, then the focus node is used as reference node.
"BLOCK": Selects all nodes between the focus node and the initial block-marking node defined by MARKSTART
"CLEARALL": Clear the selection of all nodes
"MARKALL": Selects all nodes
"INVERTALL": Inverts the selection of all nodes
MARKEDid (non inheritable): The selection state of the specified node, where id is the specified node identifier. If id is empty or invalid, then the focus node is used as reference node. Can be: YES or NO. Default: NO
MARKEDNODES (non inheritable): The selection state of all nodes. It is/accepts a sequence of '+' and '-' symbols indicating the state of each node ('+'=selected, '-'=unselected. When setting this value, if the number of specified symbols is smaller than the total count then the remaining nodes will not be changed. Can be set only when MARKMODE=MULTIPLE, can also be get when MARKMODE=SINGLE.
MARKMODE: defines how the nodes can be selected. Can be: SINGLE or MULTIPLE. Default: SINGLE.
MARKSTART (non inheritable): Defines the initial node for the block marking, used when MARK=BLOCK. The value must be the node identifier. Default: 0 (first node).
MARKWHENTOGGLE (non inheritable): selects or clears the selection of a node when its toggle is changed. Works only if the node has a toggle. Default: No.
For these attributes "id" is the specified node identifier. If "id" is empty or invalid, then the focus node is used as the specified node.
ADDEXPANDED (non inheritable): Defines if branches will be expanded when created. The branch will be actually expanded when it receives the first child. Possible values: "YES" = The branches will be created expanded; "NO" = The branches will be created collapsed. Default: "YES".
ADDLEAFid (write only): Adds a new leaf after the reference node, where id is the reference node identifier. Use id=-1 to add before the first node. The value is used as the text label of the new node. The id of the new node will be the id of the reference node + 1. The attribute LASTADDNODE is set to the new id. The reference node is marked and all others unmarked. The reference node position remains the same. If the reference node does not exist, nothing happens. If the reference node is a branch then the depth of the new node is one depth increment from the depth of the reference node, if the reference node is a leaf then the new node has the same depth. If you need to add a node after a specified node but at a different depth use INSERTLEAF.
ADDBRANCHid (write only): Same as ADDLEAF for branches. Branches can be created expanded or collapsed depending on ADDEXPANDED.
COPYNODEid (write only): Copies a node and its children, where id is the specified node identifier. The value is the destination node identifier. If the destination node is a branch and it is expanded, then the specified node is inserted as the first child of the destination node. If the branch is not expanded or the destination node is a leaf, then it is inserted as the next brother of the leaf. The specified node is not changed. All node attributes are copied, except user data.
DELNODEid (write only): Removes a node and/or its children, where id is the specified node identifier. Possible values:
- "ALL": deletes all nodes, id is ignored.
- "SELECTED": deletes the specified node and its children
- "CHILDREN": deletes only the children of the specified node
- "MARKED": deletes all the selected nodes (and all their children), id is ignored
EXPANDALL (write only): expand or contracts all nodes. Can be YES (expand all), or NO (contract all).
INSERTLEAFid, INSERTBRANCHid (write only): Same as ADDLEAF and ADDBRANCH but the depth of the new node is always the same of the reference node. If the reference node is a leaf, then the id of the new node will be the id of the reference node + 1. If the reference node is a branch the id of the new node will be the id of the reference node + 1 + the total number of child nodes of the reference node.
MOVENODEid (write only): Moves a node and its children, where id is the specified node identifier. The value is the destination node identifier. If the destination node is a branch and it is expanded, then the specified node is inserted as the first child of the destination node. If the branch is not expanded or the destination node is a leaf, then it is inserted as the next brother of the leaf. The specified node is removed. User data and all node attributes are preserved.
RENAME (write only): Forces a rename action to take place. Valid only when SHOWRENAME=YES.
RENAMECARET (write only): the caret’s position of the text box when in-place renaming. Same as the CARET attribute for IupText, but here is used only once after SHOWRENAME_CB is called and before the text box is shown.
RENAMESELECTION (write only): the selection interval of the text box when in-place renaming. Same as the SELECTION attribute for IupText, but here is used only once after SHOWRENAME_CB is called and before the text box is shown.
SHOWRENAME (non inheritable): Allows the in place rename of a node. Default: "NO". F2 and clicking twice only starts to rename a node if SHOWRENAME=Yes.
SHOWDRAGDROP (non inheritable): Enables the internal drag and drop of nodes, and enables the DRAGDROP_CB callback. Default: "NO". Works only if MARKMODE=SINGLE. Drag & Drop attributes are NOT used.
DRAGDROPTREE (non inheritable): prepare the Drag & Drop callbacks to support drag and drop of nodes between trees (IupFlatTree only), in the same IUP application. Drag & Drop attributes still need to be set in order to activate the drag & drop support, so the application can control if this tree will be source and/or target. Default: NO.
DROPFILESTARGET (non inheritable): Enable or disable the drop of files. Default: NO, but if DROPFILES_CB is defined when the element is mapped then it will be automatically enabled. This is NOT related to the drag&drop of nodes inside the tree.
DROPEQUALDRAG (non inheritable): if enabled will allow a drop node to be equal to the drag node. Used only if SHOWDRAGDROP =Yes. In the case the nodes are equal the callback return value is ignored and nothing is done after.
Drag & Drop attributes are supported, but SHOWDRAGDROP must be set no No.
