Reload Picker

A developper hack to reload the Dreamwall picker without having to restart Maya each time.

# If the picker is not in a known PYTHONPATH.
import sys
sys.path.insert(0, "<dwpicker path>")

# Code to clean modules and relaunch a Dreamwall picker with updated code.
try:
    # Important step to not let some callbacks left behind.
    dwpicker.close()
except:
    pass

for module in list(sys.modules):
    if "dwpicker" in module:
        print("deleted: " + module)
        del sys.modules[module]

import dwpicker
dwpicker.show()

Create buttons to picker programmaticaly.

from maya import cmds
import dwpicker
from dwpicker.templates import BUTTON


def add_button(options, refresh_ui=True):
    """
    @param dict options:
        This is a dictionnary of the shape options. List of possible options
        are can be found here dwpicker.templates.BUTTON
        (too much very many long to be documented here ;) )
    @param bool refresh_ui:
        this update the ui. Can be disabled for loop purpose.
    """
    button = BUTTON.copy()
    button.update(options)
    picker = dwpicker.current()
    if picker is None:
        cmds.warning('No picker found')
        return

    picker.document.add_shapes([button])

    if refresh_ui:
        picker.document.changed.emit()


options = {
    'text.content': 'Button',
    'shape.left': 250,
    'shape.top': 150,
    'shape.width': 120.0,
    'shape.height': 25.0,
}
add_button(options)

Embeb custom picker widget.

Example for a TD who wants to include a picker in a custom UI: This is the simplest possible setup to make it functional without relying on the main application.

import json
from dwpicker.interactive import Shape
from dwpicker.document import PickerDocument
from dwpicker.picker import PickerStackedView
from dwpicker.qtutils import set_shortcut
from PySide2 import QtCore

with open('-picker_file_path-', 'r') as f:
    data = json.load(f)
document = PickerDocument(data)
view = PickerStackedView(document=document editable=False)
view.register_callbacks()
view.setWindowFlags(QtCore.Qt.Tool)
view.reset()
set_shortcut('F', view, view.reset)

view.show()
