How best to make Undo?

[pietro_72_]

I'm trying to add an Undo method to my program to correct errors made by the user in the construction of the 3D object, should I create a sort of log of the operations performed in order to possibly cancel them?

Currently it does not have a log of the operations performed

If you are using operations (e.g. RAddObjectsOperation), undo / redo is automatically built in.

Thank you

I had used 3

Code: Select all

op = new RModifyObjectsOperation ();

starting at line 1837
in

Code: Select all

OrthogonalProjections.prototype.slotUndo = function () {

in line 1800
to cancel the 3 graphic representations in orthogonal projections of a 3D vertex
you mean in this sense?
But I don't think that the operations can operate on the multidimensional array that I made in which I save the 3D data, or am I wrong? (for example see line 1816)

A ... another thing how can I get the name of the path and the dwg / dxf file the user is working on? I thought of making a nearby file with the same name in which to save the data of the 3D entities under construction

Operations keep track of the changes they make on a document. These changes can be undone / redone. If you change things other than the document, that is not covered.
