Suppose if the push buttons are 'Cube' and 'Duplicate', and I checked
scale_x withthe min value being 1.0
while max value is 2.0, how should I write in `create_node()`?
Should I store such variables as a dictionary or some sort so that it will
be easier for me to call and use
the values?
I am not sure what is the best way for me to call such values..
FYI, I have quite some widgets in my ui in which I need them for my new
node creations
First, I would recommend repeating string literals as little as possible.
It is prone to error if you make a typo somewhere or change the naming.
TYPE_CUBE = "Cube"
ACTION_DUP = "Duplicate"
def which_geo(self):
if self.geo_btn.text() == TYPE_CUBE:
...
def which _cmd(self):
if self.cmd_btn.text() == ACTION_DUP:
...
In order to handle these types and actions more dynamically, as you
request, you could accomplish as simply as with a dictionary, or you could
organize things into classes.
TYPE_SPHERE = "Sphere"
TYPE_CUBE = "Cube"
ACTION_DUP = "Duplicate"
ACTION_INST = "Instance"
def sphere_duplicate(*args, **kwargs):
#...
action_map = {
TYPE_SPHERE: {
ACTION_DUP: sphere_duplicate,
ACTION_INST: sphere_instance,
},
TYPE_CUBE: {
ACTION_DUP: cube_duplicate,
ACTION_INST: cube_instance,
},
}
This creates a mapping of object types to actions and functions.
If you wanted to be more organized than this, you could do it with classes.
class ObjectActioner(object):
NAME=""
def callByName(self, name, *args, **kwargs):
name = name.lower()
fn = getattr(self, name)
return fn(*args, **kwargs)
def duplicate(self, *args, **kwargs):
raise NotImplementedError()
def instance(self, *args, **kwargs):
raise NotImplementedError()
class Sphere(ObjectActioner):
NAME = "Sphere"
def duplicate(self, *args, **kwargs):
#...
def instance(self, *args, **kwargs):
#...
class Cube(ObjectActioner):
NAME = "Cube"
#...
object_map = {
Sphere.NAME: Sphere,
Cube.NAME: Cube,
}
Once you have some kind of mapping, then it is just a matter of looking up
the correct object or function and passing it the arguments in your
create_node() function. This would be instead of having to do complicated
"if then" logic in create_node()
