I have a question, on pie menus, when using pie.operator, the pie works normally, you can draw really fast in a direction and that works well.
If you use, row.operator, you need to be exactly on the button to activate it.
The direction doesn’t work anymore.
From what I understand, you are trying to do some custom layout inside a pie menu, instead of just providing a list of items? That’s not going to work, it’s undefined then which item corresponds to which area of the pie.
Maybe there can be some better heuristic, but I would not expect this to be supported now.
I added custom icons to my addon and it seems on 2.79, if we use custom icons and pie.operator and there is a report message, the pie wait for the report to disapeer.
if I use row.operator, it works fine.
I have the same issue with the screencast key addon, the pie wait and blender freeze.
I worked fine before 2.79.
So, my only way is to use row. operator, but I lose the fast workflow of the pie menus.
One approach that might work would be for the pie menu to automatically select the first operator in the first row or column of a slice, if you didn’t point inside the rectangle of any of the other items.
The OPEN LOOK user interface developed at Sun had menu buttons (buttons in a panel that pop up a menu, or the buttons within a menu that pop up submenus) that supported the notion of a “default item” that you could change by control-left-clicking on the desired default item. Clicking on the menu button with the left mouse button was a shortcut to select the default item from that button’s menu. The default item has an oval ring around it.
I think something like that would be a good way for pie menus to let the user select any of the multiple items in the same slice to act as the “default” item you get when you gesture into the slice quickly.
