Maya pcde2 UI 获取 cleanedit 值

Question

我开始使用 QtCreator 为 Maya 2017 创建一个 UI 小工具。QtCreator 给了我这个 .ui 文件：

<?xml version="1.0" encoding="UTF-8"?>
<ui version="4.0">
 <class>DockWidget</class>
 <widget class="QDockWidget" name="DockWidget">

我有这段代码显示我的 UI :

import maya.cmds as cmds 
from PySide2.QtWidgets import *
from PySide2.QtCore import *

if cmds.window(main_window, ex = True):
    cmds.deleteUI(main_window)

main_window = cmds.loadUI(uiFile = "C:/Users/thornydre/Desktop/attreditorui.ui")
cmds.showWindow(main_window)

def displayCommand(e):
    print(attr_name_textfield.text())
    print(attr_value_textfield.text())

def submitCommand(e):
    attr_name = attr_name_textfield.text()
    attr_value = attr_value_textfield.text()

    is_string = False

    try:
        new_attr_value = float(attr_value)
        if float(attr_value) % 1 == 0:
            new_attr_value = int(attr_value)
    except:
        is_string = True
        new_attr_value = attr_value

    print(new_attr_value)

    for name in cmds.ls(sl = True):
        if is_string:
            cmds.setAttr(name + "." + attr_name, new_attr_value, type = "string")
        else:
            cmds.setAttr(name + "." + attr_name, new_attr_value)

def cancelCommand(e):
    cmds.deleteUI(main_window, window = True)

如果我点击我的 display_button，我会出错：

# Result: dockWidgetContents|display_button # 
# Error: AttributeError: file <maya console> line 12: 'bool' object has no attribute 'attr_name_textfield' #

我尝试使用 QtWidgets.QWidget 的子类来实现它，正如我在互联网上的某个地方找到的那样，但我并没有真正找到任何关于如何正确构建它的教程：ui =15=]

from PySide2 import QtCore, QtGui, QtWidgets, QtUiTools

class Interface(QtWidgets.QWidget):
    def __init__(self, parent = None):
        super(Interface, self).__init__(parent)
        ui_filename = "C:/Users/thornydre/Desktop/attreditorui.ui"
        ui_file = QtCore.QFile(ui_filename)
        ui_file.open(QtCore.QFile.ReadOnly)
        self.ui = QtUiTools.QUiLoader().load(ui_file, parentWidget=self)
        ui_file.close()

    def connectInterface(self):
        QtCore.QtObject.connect(self.displayCommand, QtCore.SIGNAL("clicked()"), self.displayCommandWin)

    def displayCommand(self):
        print(self.attr_name_textfield.text())
        print(self.attr_value_textfield.text())

def main():
    global ui
    ui = Interface()

if __name__ == "__main__":
    main()

同样的事情，UI 出现了，但是点击 display_button

实际上没有任何反应

Answer 1

您第二次尝试 class 似乎不错，但无法执行 displayCommand 是完全正常的，您的按钮未连接到您的方法。

只需删除您的 connectInterface 方法，并在 ui_file.close() 之后立即复制： self.ui.display_button.clicked.connect(self.displayCommand)

它应该工作得更好 :)（而且您还必须使用 eyllanesc 解决方案来访问小部件值）
