programmatic way to determine if in a macro

[shevitz]

Howdy,

I have a custom model with undo/redo implemented via QUndoStack. Some of
my operations require macros with some complicated logic. Is there any way to
programmatically determine if you are currently inside an uncompleted macro?

thanks,
Danny

If you only create macros by creating commands with parents then your commands can check their contructor's "parent" argument to see if they are part of a macro. You can even access the parent's list of children to see if there are more commands to follow.

Thanks for the response. This doesn't work so well for me though. Currently, my macros are defined in the view, since that is where the composite actions happen (like copy/delete for DnD "move"). The atomic commands happen in the model.
They don't know anything about the view and the macros living there, so it is hard to set command parents.

There is another problem, too. I need to check whether there is macro underway at some point in the view code. I need to decide whether to end the macro or not. I have no handle to a command to see whether it is part of a macro.
Parents would let me if a command is part of a macro, but not whether a macro is underway or completed.

thanks again,
Danny

It's hard for me to imagine what is going on in your program. By the way, did you follow the QQ article on using undo/redo with the model-view architecture?
