[Closed] dotNet UI

You need to read about string representations:

Yes, I think you are right. I will look into this as it has the functions/syntax that I need. Still quite new to dot net in max, but its already proving to be a good move.

Thanks again.

Ok, so have been flapping about and eating pizza and M&Ms for a day, so my sugar levels have hit euphoric levels. I have resolved a lot of the areas I was looking to develop, due largely in part to the help I have been given here, Paul Neale, LoneRobot and others, so thanks very much. I wanted to create a dot net form with a treeview, much like the Paul Neale version, but using just a dot net form. As others who are learning will no doubt want to try this, I have added some code below that is a simple form, a treeview and a button which populates the treeview when clicked. There needs to be a hierarchy/hierarchies in the scene prior to clicking the button. It is mostly a reinterpretation of the Paul Neale example, so 97% of the credit must go to him.
I am going to develop it further as I need to add some mouse actions to the items in the treeview, butthat is fun for another day.

Thanks again everyone. :buttrock:

Thanks for the organization but the reason I laid it out like that is so that other people who are new to this would be able to see it laid out in a way that is more conducive to their learning. The format originally included indentation, but pasting it in from my script removed this. As with all things though, one persons way of learning will differ from others, so its good to now have both versions for people to refer to.

A more complete version will soon be coming.

Thanks again

All is good in the dot net form but having a little issue with the population. When I make the objects that I need via the other controls, the treeview is populated. If I then append the objects, another hierarchy is mde in the treeview, so I want the treeview to only have one version of the hierarchy when I add or subtract items from it. I am sure it will be a case of clearing the view and rebuilding it, but my brain is full at the moment and I cannot see the woods for the tree (view).

Hahah. I am a comedian. Not.

Cheers

Good evening chaps, the dot net form is going great, amended script below. I have been looking at creating a rclick menu and have the code for creating the control, but am having a little trouble getting the rclick to work on the treeview nodes.

aContextMenu = dotNetObject “System.Windows.Forms.ContextMenuStrip”
aContextMenu.RenderMode = aContextMenu.RenderMode.system
mySep1 = dotNetObject “System.Windows.Forms.ToolStripSeparator”

deleteSel = dotNetObject “System.Windows.Forms.ToolStripMenuItem” “Delete item”

aContextMenu.Items.Add deleteSel
aContextMenu.Items.Add mySep1

The above is what I want the menu to contain (at this time) but I am unclear about where it I need to refer to it when the nodes are made. I thought it would need to go in the populate function, but I think I may be calling it incorrectly.

The UI has two buttons, make tree will populate the treeview with existing scene hirarchies, the other button will delete the selected items, but its currently not working, but I am not bothered about that at this time, I have it working in my full script. If anyone can shed some light on this, as always, I would very much appreciate the pointers.

Thanks

Is there a way to make it so I can select multiple items in the treeview?

The only way I believe is to use the checkbox property of a tree node. You can set multiple tree nodes to be checked.

There’s no built-in way, you’ll have to create your own treeview.

That’s a bummer. I was hoping that would not have to be the route. Does anyone have examples of how to do something like this?
