Invoke constraint popup on constraint creation

[hlorus]

Allows to quickly enter a dimension value when adding a dimensional constraint. Ideally allows to directly enter a number.

A question about this; I can see a smal dialog that shows on the bottom of the screen when creating a constraint.

Which part of the code is responsible for creating it? Would that window qualify for punching in the numbers if we can give focus to it?

[hlorus]

Afaik that's called the operator redo panel. An operator can define a draw method which will be used to draw that panel. There's likeley no support to give it focus, therefor i don't think that's the right approach.

So we we want a pop up right next to the entity/constraint we create in the 3D view?

Example from fusion 360

Yep, well basically just invoke the menu that appears when you click on a constraint.

Founds the proper thing we want to use from the documentation: Panels (and not menus)

https://docs.blender.org/api/current/bpy.types.Panel.html

Which you can spawn using Operator.draw(), and we can even pass the UILayout element to my_constraint.draw_props(layout) to reuse the menu items from the right-click menu :smile:

I'll try making a prototype this weekend if nobody else is tackling this :)

I've tried implementing the functionality already, spawning the menu isn't a big deal, the bigger problem is to activate the value property so users could directly enter a number. IMO that's needed otherwise it just feels annoying.

The layout type has some attributes which i though would work for this, "active_default" and "activate_init" but that doesn't seem to be the case... https://docs.blender.org/api/current/bpy.types.UILayout.html

I've posted a bug report at blender regarding the activate_init issue: https://developer.blender.org/T101113

I guess we could do a basic text parser for now if only text input work with activate_init, might also be helpful for people who want to put units in the input, but that would be secondary .

True but i wouldn't recommend such a workaround, this task is really just a quality of life improvement.

That's already supported with Integer/Float properties.
