The previous implementation of deletion from treeview was insignificant since a selector erased from treeview was saved to document because it was not removed from XML representation of the tree too.
Modification of content in the style node of XML tree is a complicated process. Tried it but not very efficient and accurate. Instead of modifying the content, I cleared the node’s content and set its value corresponding to the selectors left in the selectorVec. The vector and content are cleared using following lines:
Next I will be moving to adding and deleting objects to selectors using buttons at the beginning of every row in the treeview.
