class TGListTreeItem


TGListTree and TGListTreeItem

A list tree is a widget that can contain a number of items
arranged in a tree structure. The items are represented by small
folder icons that can be either open or closed.

The TGListTree is user callable. The TGListTreeItem is a service
class of the list tree.

A list tree can generate the following events:
kC_LISTTREE, kCT_ITEMCLICK, which button, location (y<<16|x).
kC_LISTTREE, kCT_ITEMDBLCLICK, which button, location (y<<16|x).

Function documentation

TGListTreeItem(TGClient* fClient = gClient, const char* name = 0, const TGPicture* opened = 0, const TGPicture* closed = 0, Bool_t checkbox = kFALSE)

 Create list tree item.

~TGListTreeItem()

Bool_t HasCheckedChild(Bool_t first = kFALSE)

 Add all child items of 'item' into the list 'checked'.

Bool_t HasUnCheckedChild(Bool_t first = kFALSE)

 Add all child items of 'item' into the list 'checked'.

void UpdateState()

 Update the state of the node 'item' according to the children states.

void CheckAllChildren(Bool_t state = kTRUE)

 Set all child items of this one checked if state=kTRUE,
 unchecked if state=kFALSE.

void CheckChildren(TGListTreeItem* item, Bool_t state)

 Set all child items of 'item' checked if state=kTRUE;
 unchecked if state=kFALSE.

void Rename(const char* new_name)

 Rename a list tree item.

void SetCheckBox(Bool_t on = kTRUE)

 Set a check box on the tree node.
