[Closed] updating object names in listbox or listview

thanks for the speedy reply Bobo! i’m am not yet an advanced scripter and i’m unfamiliar with the concepts you mentioned. I quickly checked the maxscript refererence and it looks like callbacks might be easier to get into at this stage but which would you recommend using?

Also, a bit off topic but are you planning anymore maxscript dvds anytime soon?

thanks again bobo you’ve been most helpful as always

gravey i thought i will reply to this thread as you might have been working on listview…

the labeledit property of listview only allows u to edit the first cell of each column… whereas i want two subitem cells to be editable by user. cant find any such editable property in the reference. is this possible?

Unfortunately, subitems cannot be dynamically edited in mxs. C++ allows you to subclass the control allowing you to add all kinds of functionality to it, but this can’t be done using maxscript. The only way I know of is to use a standard editTest control. By querying the subitem’s position you could move the editText control to that location/size. Then, by using the editText control’s events (eg. onChange) you can update the subitem’s contents accordingly.

This gets tricky though when the cell is outside the listviews’ borders. Then you’d need to get the current scroll positions and add those to the location of the subitem.

If you need any help with this I’ll try to post an example of how this could be done.

Cheers,
Martijn

One would think this is a trivial thing to do, but unfortunately it’s not…

comeon u guys… u are elite… if you cant do it then who will

my listview gets all layer names in scene… i need two editable fields to enter some properties for each layer in the listview. those properties like a 1.material prefix will prefix all the materials in that layer and 2.mesh file name that gets written to the file i format to with each material…

now out of the topic i have another problem:
like i am checking each layer and going through each geometry object in that layer to get a list of unique materials… those unique materials are stored in a temp array called arrmultimaterial = multimaterial()… i used the code below to assign the unique materials found to a new slot in the temp arrmultimaterial array

arrmultimaterial.material[i] = g.material

everything was working fine until i tried to add a prefix to the material name right after it

arrmultimaterial.material[i] = g.material
   arrmultimaterial.material[i].name = "L1_" + arrmultimaterial.material[i].name

as soon as i add the prefix code the actual materials of scene also get updated with the prefix… at this stage this means everytime i run the script the materials will already have a prefix and keep adding more to it… like first time L1_materialname, secondtime L1_L1_materialname and so on

i dont understand how can they update now when i am not issuing any command to do so… because i am also sorting the arrmultimaterial and it doesnt update the actual materials when i sort it so why now?

The easiest way to do this is to add two text fields below the listview control. Whenever the user selects a row in the listview, the text fields can be used to edit that particular row. If you need any help with this, I can probably post an example script tomorrow.

This above command stores an instance of the original material in the array. So whenever you modify an item in the arrmultimaterial array, it will affect the original material as well. If you want to create a copy of the original material instead, you should use:

arrmultimaterial.material[ i ] = [b]copy[/b] g.material

This will create a copy instead of an instance, allowing you to modify its properties without affecting the original material.

Hope this helps,
Martijn

great one Martijn… thank you for that, now i feel a lot better after knowing that as i understand whats happening with it… it would be great if you can provide an example code because i am only about 1 week old to maxscript and the rollouts have taken me a lot of time, even more that doing the whole script itself.

this is my listview rollout code… i need to add editable text feature to the second and third column but after trying the fake textbox thing i cant seem to get it to work… please someone who knows how to do the move textbox to position on click give an example… and how to access its values when the listview item is clicked.

 
rollout layers_listview "Layer Options"
		width:325 height:155
(
	
	fn initListView lv =
	(
		lv.gridLines = true  
		lv.View = #lvwReport  
		lv.fullRowSelect = true 
		lv.backColor = color 224 224 224 --225 215 210
		lv.checkboxes = true
		lv.LabelEdit = #lvwManual
	
		layout_def = #(#("Layer Name",120), #("Input 1",60), #("Input 2",120))

			column = lv.ColumnHeaders.add() 
			column.text = i[1]
		)
	
		 LV_FIRST = 0x1000

					li.text = renderLayers[i] as string
					
				sub_li = li.ListSubItems.add()
					sub_li.text = "lod"

				sub_li = li.ListSubItems.add()
					sub_li.text = "mesh file" -- try((o.mesh.numverts) as string)catch("--")
			)
		)
	) 
	
	activeXControl lv_objects "MSComctlLib.ListViewCtrl" width:321 height:125 align:#left offset:[-10,0]
	on layers_listview open do

		initListView lv_objects
		fillInSpreadSheet lv_objects
	) 
)
createdialog layers_listview pos:[730,95] style:#(#style_sysmenu,#style_titlebar,#style_minimizebox)

the listview is updated on rolloutopen with all the layers in scene that start with “Tools_” so pls add a few layers called tools_XXX to see it work.
