How to programmatically set "Max Entry Length" for a tree cell

[vix]

I want to specify a N_MAX maximum length for the cell names of a tree, so that when the user press F2 key to rename it, he's not allowed to enter more than N_MAX characters.

For the items already existent in the uir file, I'm able to get this behaviour setting Edit Tree >> Edit Columns/Cells >>Edit Cell >> Max Entry Length to 5 (see attached img03.png).

When the user tries to rename this item, he's not allowed to enter more than 5 characters (see attached img02.png).

But how can I set this attribute for the items programmatically added (for example through InsertTreeItem( )).

I haven't been able to find the right attribute, because the cell attribute ATTR_LABEL_TEXT_LENGTH (that seems more or less what I'm looking for) is "not settable"

I suppose there is no way other then preprocess the item name and issue InsertTreeItem only if correct, passing the correct label to it.

You could for example have a small panel for the user to insert the name fro the new cell, with a string control limited to 5 characters or something like this.

You found an omission in the documentation. You can use ATTR_MAX_ENTRY_LENGTH and ATTR_MAX_ENTRY_CHARS with SetTreeCellAttribute and SetTreeItemAttribute to set the max entry for a tree cell.

Thanks for reporting this and sorry for the inconvenience.
