IC Python API:File Path
- Main article: Python of the Month.
Oftentimes, you'll need to handle external files in the form of loading, writing and reading. This article will go over doing just that with Python scripting.
Required Modules
Besides the rudimentary Reallusion Python API, we'll need to use Qtwidgets to build our user interface and shiboken2 to convert the dialog window to something Python can understand.
import RLPy
from PySide2 import QtWidgets
from PySide2.shiboken2 import wrapInstance
User Interface
We'll need to create a user interface with a line at the top that shows the directory location, a button for opening the file browse dialog, and a text input to display the contents of the file.
window = RLPy.RUi.CreateRDialog()
window.SetWindowTitle("Python Path & File")
dialog = wrapInstance(int(window.GetWindow()), QtWidgets.QDialog)
dialog.setFixedWidth(500)
layout = QtWidgets.QHBoxLayout()
dialog.layout().addLayout(layout)
pathText = QtWidgets.QPlainTextEdit(readOnly=True, maximumHeight=25)
contentText = QtWidgets.QPlainTextEdit(minimumHeight=250)
button = QtWidgets.QPushButton("....", minimumHeight=25, minimumWidth=25)
layout.addWidget(pathText)
layout.addWidget(button)
dialog.layout().addWidget(contentText)
File Dialog Request
Next we'll need a definition for the file dialog procedure to populate the directory field and the contents text field.
def open_file():
file_path = RLPy.RUi.OpenFileDialog("Python Files(*.py)")
if len(file_path) > 0:
pathText.setPlainText(file_path[0])
f = open(file_path[0], "r")
contentText.setPlainText(f.read())
f.close()
button.clicked.connect(open_file)
window.Show()
Using QT only
This was the previous code for open file dialog. It's been deprecated for Reallusion's more convenient API and kept here for posterity.
def open_file():
file_dialog = QtWidgets.QFileDialog()
file_dialog.setNameFilter("*.py")
file_dialog.exec()
if(len(file_dialog.selectedFiles()) > 0):
pathText.setPlainText(file_dialog.selectedFiles()[0])
f = open(file_dialog.selectedFiles()[0], "r")
contentText.setPlainText(f.read())
f.close()
button.clicked.connect(open_file)
window.Show()
-
File request dialog is a standard Window's file browser. Notice that we are restricting the search to .py files with the filter attribute. -
The top field is populated with the file location and the bottom field for the contents of the file.
Everything Put Together
You can copy and paste the following code into a PY file and load it into iClone via Script > Load Python.
import RLPy
from PySide2 import QtWidgets
from PySide2.shiboken2 import wrapInstance
window = RLPy.RUi.CreateRDialog()
window.SetWindowTitle("Python Path & File")
dialog = wrapInstance(int(window.GetWindow()), QtWidgets.QDialog)
dialog.setFixedWidth(500)
layout = QtWidgets.QHBoxLayout()
dialog.layout().addLayout(layout)
pathText = QtWidgets.QPlainTextEdit(readOnly=True, maximumHeight=25)
contentText = QtWidgets.QPlainTextEdit(minimumHeight=250)
button = QtWidgets.QPushButton("....", minimumHeight=25, minimumWidth=25)
layout.addWidget(pathText)
layout.addWidget(button)
dialog.layout().addWidget(contentText)
def open_file():
file_dialog = QtWidgets.QFileDialog()
file_dialog.setNameFilter("*.py")
file_dialog.exec()
if(len(file_dialog.selectedFiles()) > 0):
pathText.setPlainText(file_dialog.selectedFiles()[0])
f = open(file_dialog.selectedFiles()[0], "r")
contentText.setPlainText(f.read())
f.close()
button.clicked.connect(open_file)
window.Show()
