hiCreateTreeItem

Davender,

I wasn't 100% sure what you wanted, but I modified your example above (probably wise to change the variable names, since they are not exactly meaningful). I've put in bold the bits I changed. I also changed the tree callback from treeCB to MYtreeCB as this clashes with a Cadence function which unfortunately has had the prefix omitted (I've filed a CCR to get that fixed).

I also added a context menu - you mentioned a "dropdown list" - wasn't sure if that is what you wanted either.

;;----------------------------------------------------------------------------------------------

; example of adding a context menu
hiCreateSimpleMenu('MYcontextMenu "Context Menu" list("Item 1" "Item 2") list("println('item1)" "println('item2)"))

 indexTree=hiCreateTree('index)
; create two tree items and append them to the root tree
dow=hiCreateTreeItem('dow list("TD_CORE"))
hiTreeAppendItem(indexTree dow)
; create two sub-trees
dowTree=hiCreateTree('dows)
; put the two sub-trees into the two items created earlier
hiItemInsertTree(dow dowTree)
TdDigitalTree=hiCreateTree('TdDigitalTree)
TdDigitalTreeItem=hiCreateTreeItem('TdDigitalTreeItem list("TD_DIGITAL"))
hiItemInsertTree(TdDigitalTreeItem TdDigitalTree)
hiTreeAppendItem(dowTree TdDigitalTreeItem)
; add a few leaves for the dowTree and nasTree
hiTreeAppendItem(TdDigitalTree hiCreateTreeItem('cdn list("TD_DIGITAL" "XTD_DIGITAL" "verilog wreal veriloga schematic" "verilog")))
hiTreeAppendItem(dowTree hiCreateTreeItem('ibm list("VIO_SWITCH" "XVIO_SWITCH" "verilog wreal veriloga verilogams schematic" "wreal")))
hiTreeAppendItem(dowTree hiCreateTreeItem('rx list("RX" "XRX" "verilog wreal veriloga verilogams schematic" "schematic")))
hiTreeAppendItem(dowTree hiCreateTreeItem('ls list("TD_LS_CTRL" "XTD_LS_CTRL" "verilog wreal veriloga verilogams schematic" "schematic")))
hiTreeAppendItem(dowTree hiCreateTreeItem('bk list("BUCK" "XBUCK" "verilog wreal veriloga verilogams schematic" "veriloga")))
hiTreeAppendItem(dowTree hiCreateTreeItem('bo list("BOOST_3P0V" "XBOOST_3P0V" "verilog wreal veriloga verilogams schematic" "wreal")))

;hiTreeAppendItem(nasTree hiCreateTreeItem('orcl list("Oracle" 28.925 5 "Strong Sell")))
; create callback, which is called whenever any tree items are selected and which
; prints the selected item¿s description
procedure( MYtreeCB(name itemSymList)
   let(()
       while(itemSymList
            itemSym=car(itemSymList)
            println(hiGetTreeItemDescription(eval(itemSym)))
            itemSymList=cdr(itemSymList)
       )
   )
)

procedure(MYcontextMenuCB(menu form field item)
    printf("Context menu posted for item %L on form field %L\n" item field)
)


; create tree table and use indexTree as the value for ?choice
treeField = hiCreateTreeTable(
?name 'treeField
?title "TD_CORE"
?titleAlignment 'center
?headers list(list("CellName" 125 'left 'string)
list("instName" 125 'left 'string)
list("views" 250 'center 'string)
list("view" 125 'right 'string)
)
?choice indexTree
?callback "MYtreeCB"
)
; create a form
form = hiCreateAppForm(
?name 'form
?formTitle "MakeFile Configurator"
?fields list(
list(treeField 5:5 900:450 55)
)
?initialSize 500:750)

form->treeField->hiContextMenu=MYcontextMenu
form->treeField->hiShowContextMenuCallback='MYcontextMenuCB

hiDisplayForm(form)

Best Regards,

Andrew

Yes, that's possible.

Andrew.

Thanks Andrew. Can you point me to an example of how this can be done. Do i add this as an option when i am creating an item "hiCreateTreeItem" or is this option needs to be enabled when creating the TreeTable.

Thanks Andrew.

hiTreeAppendItem(dowTree hiCreateTreeItem('ls list("TD_LS_CTRL" "XTD_LS_CTRL" "verilog wreal veriloga verilogams schematic" "schematic")))

In this case on the menu if the user wants to change it from"schematic" to "schematic_edited" how can this be achieved.

hiCreateTreeItem does not have an editable option.  Appreciate if you can throw your idea on this.

If you want to be able to change it - one possibility is to have a type in field on the form which gets populated when you click on the item - and then you could type in that field to update it. There isn't a means of directly editing entries in the tree.

I don't have any good examples of dynamically changing tree forms (well I do, but I can't really post them because they're deeply embedded in other applications). In general it's just about calling the same functions based on (say) an expand callback.

Here's another simple example you might find useful to get some ideas from (written in LISP syntax, but that shouldn't matter);

Hi Andrew Beckett,

 Based on your last comment, I am doing a similar thing. When a tree item is selected, I want to update a text field in the form with the selected item's value.

The problem here is the tree table call back only returns the tree table field and selected item. How do you get the form and the rest of the field?

I do not want to use a context menu just to make the UI more intuitive.

Thanks,

Naveen

The forum guidelines ask you not to post on the end of old threads (this one is 4 years old) - because it tends to confuse the issue when multiple things get posted, plus it's much easier to get overlooked...

Assuming you're talking about the callback specified with ?callback of hiCreateTreeTable, then the simplest thing is to use a function object for the callback rather than just the name of the callback. More detail can be found if you search in the documentation for "Function object callbacks". This is a newer capability where more information is provided to the callbacks (plus it means that the callbacks can be locally scoped if you're using SKILL++). With a tree table, the callback gets passed  the field name, the form object, and the list of selected items.

If you're writing the code in SKILL language mode (rather than SKILL++), all you'd need to do is make your function take these three arguments, and then use

?callback getd('myCallbackFunction)

rather than:

?callback 'myCallbackFunction

Regards,

Andrew.

To be honest, the other way is just to call hiGetCurrentForm() inside your callback function - I should have mentioned that first!

Regards,

Andrew.
