Maya PySide2 and QSlider with connectControl to object

[5inch]

Hello Together,

please can you support me with this...

I try to connect a QSlider with an easy QWindow with simple Attributes of an object. The slider should be connected with a QTextEdit to manually edit the values. everything should be updated in realtime. I found the Python command: "connectControl" which should do the Job, but I dont get evereything up and running.

Here is my code:

from PySide2 import QtCore, QtGui, QtWidgets
import maya.cmds as cmds


class Ui_Dialog(object):
    def setupUi(self, Dialog):
        Dialog.setObjectName("Dialog")
        Dialog.resize(400, 300)

        self.horizontalSlider = QtWidgets.QSlider(Dialog)
        self.horizontalSlider.setGeometry(QtCore.QRect(60, 60, 160, 22))
        self.horizontalSlider.setOrientation(QtCore.Qt.Horizontal)
        self.horizontalSlider.setObjectName("horizontalSlider")
        self.horizontalSlider.setTickInterval(1000)
        self.horizontalSlider.setSingleStep(0.1)
        self.horizontalSlider.setRange(0, 1000)
        

        self.textEdit = QtWidgets.QTextEdit(Dialog)
        self.textEdit.setGeometry(QtCore.QRect(230, 60, 41, 31))
        self.textEdit.setObjectName("textEdit")
        
        self.horizontalSlider.valueChanged.connect(self.print_it)

    def retranslateUi(self, Dialog):
        Dialog.setWindowTitle(QtWidgets.QApplication.translate("Dialog", "Dialog", None, -1))
        
        
    def print_it(self,x):
        try:
            print float(x)
            self.horizontalSlider.valueChanged[int].connect(self.textEdit.setText(str(x)))
            
        except Exception as e:
            print e

if __name__ == "__main__":
    if cmds.window("Dialog", q = True, ex = True):
        cmds.deleteUI("Dialog")

Dialog = QtWidgets.QDialog()
ui = Ui_Dialog()
ui.setupUi(Dialog)
Dialog.show()

and this is the code I found from the Maya docs:

import maya.cmds as cmds

sphereNames = cmds.polySphere()
sphereName = sphereNames[0]
window = cmds.window()
cmds.columnLayout()
cmds.text( l='X Value:' )
cmds.floatField( 'xx' )
cmds.connectControl( 'xx', '%s.tx' % sphereName )
cmds.text( l='Visibility' )
cmds.checkBox( 'vis' )
cmds.connectControl( 'vis', '%s.visibility' % sphereName )
cmds.floatFieldGrp( 'rot', l='Rotation:', numberOfFields=3 )
# index 1 would be the text label
cmds.connectControl( 'rot', '%s.rx' % sphereName, index=2 )
cmds.connectControl( 'rot', '%s.ry' % sphereName, index=3 )
cmds.connectControl( 'rot', '%s.rz' % sphereName, index=4 )
cmds.showWindow( window )

and the result:

Many thanks for any support on this.

I think that command is meant for maya ui such as one build by cmds, not raw pyside widgets.

Same effect could possibly be implemented using 

http://help.autodesk.com/cloudhelp/2018/ENU/Maya-SDK/cpp_ref/class_m_node_message.html#add4ee645b2ce...

wire the callback to your ui and you should be receiving updates.

Also this line here

self.horizontalSlider.valueChanged[int].connect(self.textEdit.setText(str(x)))

Shouldn't it be something like this?

self.horizontalSlider.valueChanged.connect(lambda x: self.textEdit.setText(str(x)))

Hello olarn,

sorry for the late reply, I was off for the last days.

Good points you are highlighting here, many thanks.

I want to build the UI now with Maya UI commands, may be better supported then pySide2.

Im looking for a good example for layouts for the UI. Any tip?

Best regards, 5inch

The laziest possible way is to build the whole ui in designer and load it by this command.

From maintainability standpoint I wouldn't recommend it but you be the judge.
