I have a custom pyqt ui with a list widget in it. I'd like that list widget to update if the user changes context in the network view. e.g. from object to SOP to ROP (Driver) etc. I believe I can utilise the ContextEvent handler but I don't know how to initiate it. Can anyone help me out or point me to a script I can dissect? https://www.sidefx.com/docs/houdini/hom/network.html I briefly flirted with the pypanel nodepath hook but ideally I'd like to run this from a toolshelf too. https://www.sidefx.com/docs/houdini/examples/python_panels/nodepath.html

As the title suggests, how do you drag and drop Qt data on to a parameter? I was able to use this example as reference. But in my case the i couldn't make the drop event register. The code i have now kinda works, but the dropped text is wierd. What's the right way to do this....could use some help! I'm attaching an example code. from PySide2.QtWidgets import * from PySide2.QtCore import * from PySide2.QtGui import * import hou class TreeWidget(QTreeView): def __init__(self): super(TreeWidget, self).__init__() self.setDragEnabled(True) # def dragEnterEvent(self, event): # print "dragEnterEvent" # event.acceptProposedAction() def mouseMoveEvent(self, event): print "MoveEvent" mimeData = QMimeData() data = (self.selectedIndexes()[0]).data() mimeData.setText(data) drag = QDrag(self) drag.setMimeData(mimeData) drag.exec_(Qt.CopyAction | Qt.MoveAction, Qt.CopyAction) # def dropEvent(self, event): # print "dropEvent" # mime_data = event.mimeData() class Example(QWidget): def __init__(self): super(Example, self).__init__() self.build_ui() def build_ui(self): self.setGeometry(300, 300, 150, 250) self.setParent(hou.qt.mainWindow(), Qt.Window) mainlayout = QVBoxLayout() self.setLayout(mainlayout) self.tree_widget = TreeWidget() self.tree_widget.setRootIsDecorated(False) self.tree_widget.setHeaderHidden(True) model = QStandardItemModel() self.tree_widget.setModel(model) mainlayout.addWidget(self.tree_widget) for i in range(10): parent_item = QStandardItem('Example_{0} \nnew_line_{0} \n '.format(i)) model.appendRow(parent_item) def dragEnterEvent(self, event): event.acceptProposedAction() # def dropEvent(self, event): # print "dropEvent 2" # str = event.mimeData().text() # event.acceptProposedAction() ex = Example() ex.show()

Hi guys, I'm having a simple shelf tool in Houdini: from PySide2 import QtCore, QtGui, QtWidgets class PysideTest(QtWidgets.QMainWindow): def __init__(self, parent=None): super(PysideTest, self).__init__(parent) test = QtWidgets.QWidget() self.resize(800, 800) self.setWindowTitle("This is a test") hbox = QtWidgets.QHBoxLayout() edit = QtWidgets.QLineEdit() edit.setObjectName("QLineEditCustom") print edit.styleSheet() hbox.addWidget(edit) test.setLayout(hbox) self.setCentralWidget(test) #self.setBackgroundRole(QtGui.QPalette.ColorRole.Base) self.setBackgroundRole(QtGui.QPalette.Dark) self.setAutoFillBackground(True) self.show() def run(): mainWidget = hou.qt.mainWindow() css = mainWidget.styleSheet() css_filter_str = 'QLineEdit#QLineEditCustom\n{background: rgb(255, 255, 255); color: rgb(255, 0, 255); selection-background-color: red}' css = "\n".join([css, css_filter_str]) mainWidget.setStyleSheet(css) obj = PysideTest(mainWidget) run() When I press on the shelf tool button I get my UI popping up nicely. This only works if I give the class "PysideTest" the parent "mainWidget", otherwise the UI disappears immediately after clicking on the shelf tool. Now because I'm giving it the "hou.qt.mainWindow()" as a parent, the UI inherits the CSS from its parent. In order to override the CSS on the QLineEdit for instance, I can't just simply write edit.setStyleSheet(), this is being ignored. Instead, I apparently have to grab the CSS from the mainWidget (which is a string) and append my own line using the identifier "#QLineEditCustom". This way it's possible for me to adjust the text color (in my case pink) as well as the selection background color (in my case red), however I'm unable to change the background color of the QLineEdit, which is what I actually want to do. > background: rgb(255, 255, 255) does not work > background-color: rgb(255, 255, 255) does not work either What am I missing here guys? I really like the fact that I can just inherit the CSS from Houdini, but it would be great if there was a more straight forward way of customizing it. The other question I have, what if I wanted to change the background color based on the user text input from color A to color B dynamically, how would I approach that? Thanks in advance, Manu

I know the icons are stored here: hicon:/SVGIcons.index? and the short form to add one to a tool or shelf would be, for example, BUTTONS_add.svg. But how can I point to one of these icons from a pyside gui? Is there a fullpath I can use?

Hello everyone, i´m writing a tool in Pyside and i can´t figure out how to set the color of the individual cells in a QTableView. Here is an example, which demonstrates the problem: from PySide import QtCore, QtGui import hou class cellColor(QtGui.QDialog): def __init__(self): QtGui.QDialog.__init__(self) self.resize(297, 174) self.verticalLayout = QtGui.QVBoxLayout(self) self.tableview = QtGui.QTableView(self) self.verticalLayout.addWidget(self.tableview) # without parenting the ui to houdini, i can set the cell colors self.setParent(hou.ui.mainQtWindow(), QtCore.Qt.Window) model = QtGui.QStandardItemModel() item1 = QtGui.QStandardItem("Color Red") item1.setBackground(QtGui.QColor(240,10,10)) item2 = QtGui.QStandardItem("Color Green") item2.setBackground(QtGui.QColor(10,240,10)) model.appendRow([item1,item2]) self.tableview.setModel(model) testwindow = cellColor() testwindow.show() testwindow = cellColor() testwindow.show() Is there a way to set the color of the cells, when the window is parented to Houdini? Thanks for all replies

In the current tool I'm building for H16, I have a UI in which I would like to have different options available to the user depending on their selection. It would be ideal if these options can change without the user having to close and relaunch the UI every time. In short, I need a way to capture a signal emitted when the user selects node(s). I looked around the HOM and didn't see anything that looks like it gets called whenever a node is selected, just queries for currently selected nodes. Does anyone know how I could trigger something in my UI whenever the user selects different nodes? Thanks! Chris

Hi guys, This has boggled my mind for a while now. I have a OTL that has a tool script attached to it (Type Properties > Tool section), that evokes a PySide interface. The problem is that when I run the tool a few times, every single time a new instance of the interface is being opened, while the old one is still alive. So I'm ending up with lots of open windows of the same tool after a while which is super annoying. How can I prevent this from happening? I want to have only one single instance running at a time, basically close the old window if the tool is run again. Here's a really simple example that we could use as a test case. (Same problem if I run it as a shelf tool) from PySide import QtGui, QtCore class Window(QtGui.QWidget): """Simple Test""" def __init__(self): super(Window, self).__init__() self.setGeometry(50, 50, 500, 300) self.setWindowTitle("test") self.home() def home(self): btn = QtGui.QPushButton("Test Button") a_label = QtGui.QLabel("Test Label") qvbox = QtGui.QVBoxLayout() qvbox.addWidget(btn) qvbox.addWidget(a_label) qvbox.insertStretch(2) self.setLayout(qvbox) def run(self): self.show() main = Window() main.run() Some where I read that using the QEventLoop might help to detect running instances with hou.ui.eventLoopCallbacks(), but after trying some stuff for a few hours, I'm at my wits end. Help here would be much appreciated Thanks!!! -
