How to select all items for a sub tree when I click its parent item?

iDave

Hi all

The following is the test code. 

root=hiCreateTree(‘root)

item1=hiCreateTreeItem(‘item1 list(“count”))

item2=hiCreateTreeItem(‘item2 list(“name”))

hiTreeAppendItems(root list(item1 item2))

tree1=hiCreateTree(‘tree1)

tree2=hiCreateTree(‘tree2)

hiItemInsertTree(item1 tree1)

hiItemInsertTree(item2 tree2)

for(i 1 1000

    count=concat(“num” i)

    hiTreeAppendItem(tree1 hiCreateTreeItem(count list(artMakeString(i))))

    name=concat(“name” i)

    hiTreeAppendItem(tree2 hiCreateTreeItem(name list(artMakeString(i))))

)

treeFiled=hiCreateTreeTable(

    ?name ‘treeField

    ?headers list(list(“info” 50 ‘center ‘string t))

    ?choice root

)

form=hiCreateAppForm(

    ?name ‘form

    ?fields list(list(treeField 5:5 300:300 0))

)

hiDisplayForm(form)

After the form pop-up, I click the item “name” , how to make all sub items for “name” selected?

Any help will be appreciated.

    Dave,

    This does it. Not sure it's a good idea though (it's rather slow - the slowness is when using hiTreeTableSelectItems with lots of items - if this is a problem in your real application, please contact customer support).

    root=hiCreateTree('root)
item1=hiCreateTreeItem('item1 list("count"))
item2=hiCreateTreeItem('item2 list("name"))
hiTreeAppendItems(root list(item1 item2))
tree1=hiCreateTree('tree1)
tree2=hiCreateTree('tree2)
hiItemInsertTree(item1 tree1)
hiItemInsertTree(item2 tree2)
for(i 1 1000
    count=concat("num" i)
    hiTreeAppendItem(tree1 hiCreateTreeItem(count list(artMakeString(i))))
    name=concat("name" i)
    hiTreeAppendItem(tree2 hiCreateTreeItem(name list(artMakeString(i))))
)
treeField=hiCreateTreeTable(
    ?name 'treeField
    ?headers list(list("info" 50 'center 'string t))
    ?choice root
    ;?callback "CCFselectTreeMembers(hiGetCurrentForm()->treeField)"
    ?callback "CCFselectTreeMembers"
)
form=hiCreateAppForm(
    ?name 'form
    ?fields list(list(treeField 5:5 300:300 0))
)

procedure(CCFselectTreeMembers(fieldName selection)
    let((tree newSelection field)
	field=get(hiGetCurrentForm() fieldName)
	newSelection=copy(selection)
	foreach(item selection
	    tree=hiGetTree(symeval(item))
	    when(tree
		newSelection=append(newSelection hiGetTreeItems(symeval(tree)))
	    )
	)
	; select items but don't trigger callback again
	hiTreeTableSelectItems(field newSelection nil)
    )
)

hiDisplayForm(form)
