[Closed] Get all selected modifiers from stack

selected modifiers make sense only as UI solution. there is no flag (as i know) that indicates that a modifier selected in the stack.

so … the trick can be to find ListBox control of modifier stack, and check what items are selected. after that use these indexes to get modifiers from the currently selected object.

you have also check the command mode, number of selected nodes, etc.

but the idea is:

-- get "Command Panel" hwnd
hwnd = (windows.getChildHWND #max "Command Panel")[1]
-- get modifier stack listbox hwnd
list_box = for c in windows.getChildrenHWND hwnd where c[4] == "ListBox" do exit with c[1]
-- get listbox selected items
count = windows.SendMessage list_box LB_GETCOUNT 0 0
items = for i=0 to count-1 where (windows.SendMessage 0x001004F6 LB_GETSEL i 0) == 1 collect (i+1)
-- get modifiers
for k in items collect (if k > $.modifiers.count then $.baseobject else $.modifiers[k])

Awesome! Here’s a working version of it, only valid output when modify panel is active.

 LB_GETCOUNT= 0x18B
 LB_GETSEL = 0x187
 
hwnd = (windows.getChildHWND #max "Command Panel")[1]
list_box = for c in windows.getChildrenHWND hwnd   where  c[4] == "ListBox" do exit with c[1]
	 
count = windows.SendMessage list_box LB_GETCOUNT 0 0
 
items = for i=0 to count-1 where (windows.SendMessage  list_box  LB_GETSEL i 0) == 1 collect (i+1)
-- get modifiers

for k in items collect (if k > $.modifiers.count then $.baseobject else $.modifiers[k])

@DenisT – Genius! Could you use the same technique to find out which layers are selected in the Pre-Max2015 layer editor?

And for both scenarios, what happens when the list of items exceeds the height of the listbox? If the item isn’t currently being drawn on-screen does it still get flagged as selected?

technically it’s possible to read text of items. in case of layers it’s helpful because layers use unique names

I’m trying to find the HWND of the layer manager…

print (windows.getChildrenHWND #max)

Not finding it…

Cheers found it…

print (windows.getChildrenHWND 0)

#(6292968P, 65552P, 477026P, “#32770”, “Layer: 0 (default)”, 477026P, 6292968P, 477026P)

I can get the Hwnd of the SysListView32

(windows.getChildrenHWND 6292968P)[1]
#(1787606P, 6292968P, 6292968P, “SysListView32”, “List1”, 0P, 6292968P, 477026P)

I’m always a bit lost with the dark arts of the windows messages, how do you find out what messages to send???

for SysteListView32 you need another messages… i’ve googled “SysteListView32”.
the first i found http://www.codeproject.com/Questions/238246/Getting-Setting-SysListView-control-items

there i see that another messages have to be used

It might not be so simple if the object has references or if some sub object levels are expanded.

Weird find, if you rename a modifier to “RefObj” it makes its height half.
