QT Designer Widget Reference

[ixjlyons]

A bit late but maybe this'll be helpful to others landing here trying to do the same thing.

This can be done with the "Promote to ..." menu when you right click on the placeholder widget. Add a promoted class like this (might be able to use a more specific base class, not sure if it matters):

Then Add, then Promote. Then when you load the UI, it'll have an attribute with the name you give that widget in Designer that is a QtInteractor you can re-use.

An example - assumes you at least have a QPushButton named button and a widget promoted to QtInteractor named plot:

from PyQt6 import QtWidgets, uic
import pyvista as pv


class Widget(QtWidgets.QWidget):

    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)

        uic.loadUi("example.ui", self)
        # self.plot is now a QtInteractor instance
        # self.button is a QPushButton

        self.x = 0
        self.button.clicked.connect(self.add_sphere)

    def add_sphere(self):
        mesh = pv.Sphere(center=(self.x, 0, 0))
        self.plot.add_mesh(mesh)
        self.x += 1


if __name__ == "__main__":
    app = QtWidgets.QApplication([])
    win = Widget()
    win.show()
    app.exec()

example.ui

<?xml version="1.0" encoding="UTF-8"?>
<ui version="4.0">
 <class>ExampleUI</class>
 <widget class="QWidget" name="ExampleUI">
  <property name="geometry">
   <rect>
    <x>0</x>
    <y>0</y>
    <width>400</width>
    <height>300</height>
   </rect>
  </property>
  <property name="windowTitle">
   <string>Form</string>
  </property>
  <layout class="QVBoxLayout" name="verticalLayout">
   <item>
    <widget class="QtInteractor" name="plot" native="true"/>
   </item>
   <item>
    <widget class="QPushButton" name="button">
     <property name="text">
      <string>Add Mesh</string>
     </property>
    </widget>
   </item>
  </layout>
 </widget>
 <customwidgets>
  <customwidget>
   <class>QtInteractor</class>
   <extends>QWidget</extends>
   <header>pyvistaqt</header>
   <container>1</container>
  </customwidget>

Hello @zoner72 sorry for jumping in so late, did you find a solution?

I think I have an idea of you want to accomplish but I am not quite sure I understand the issue. If I understand correctly, you embed the QtInteractor in a QtDesigner UI and you want to avoid re-creating the interactor everytime you upload a dataset? 🤔

Hi @GuillaumeFavelier

Ha, yeah its been a wee while, not a problem though. I put this part to the side and started focussing on other parts of the code.
Your description is correct, that was/is indeed what I am after. Somehow I couldn't get it to work.
