I want to revive this conversation.
I converted the code to PySide2 and its all working fine, but the
event.child() has no object name most of the time.
When I open the Render View for example, the ChildPolished and ChildRemoved
events are triggered but the object name of the child is empty. I tried to
get more information about the child but the child is a QWidget that doesnt
look like the Render View at all.
Is there another way how I can identify which window got opened or close
through the event or event.child?
Here is the code I use. I hooked the eventfilter to a window to remove it
when I close it.
from PySide2 import QtCore, QtWidgets
from shiboken2 import wrapInstance
import maya.OpenMayaUI as mui
def maya_main_window():
main_window_ptr = mui.MQtUtil.mainWindow()
return wrapInstance(int(main_window_ptr),QtWidgets.QWidget)
class RenderViewFilter(QtWidgets.QDialog):
def __init__(self, parent=maya_main_window()):
super(RenderViewFilter, self).__init__(parent)
self.setWindowTitle("Test OnRenderViewOpen")
self.setMinimumSize(200, 100)
self.maya_main_window = parent
self.maya_main_window.installEventFilter(self)
def closeEvent(self, event):
self.maya_main_window.removeEventFilter(self)
def eventFilter(self, obj, event):
if obj == self.maya_main_window:
if event.type() == QtCore.QEvent.Type.ChildPolished:
child = event.child()
print(child)
print("ChildPolished")
print(child.objectName())
if 'renderViewWindow' in child.objectName():
print("OPEN Render View")
if event.type() == QtCore.QEvent.Type.ChildRemoved:
child = event.child()
print(child)
print("ChildRemoved")
print(child.objectName())
if 'renderViewWindow' in child.objectName():
print("CLOSED Render View")
return False
if __name__ == "__main__":
x = RenderViewFilter()
x.show()
I have a script that uses a scriptJob that gives me the hook to the close
and open event on a window, but I also want to make it work with
EventFilters. Here is the code with the scriptJob:
import maya.cmds as cmds
import pymel.core as pm
class WindowWatcher():
def __init__(self):
self.window_name = "renderViewWindow"
self.window_opened = False
def check_for_window_open(self):
if not self.window_opened:
if self.window_name in cmds.lsUI(windows=True):
self.window_opened = True
print("Render Window opened!")
else:
if not self.window_name in cmds.lsUI(windows=True):
self.window_opened = False
print("Render Window Closed!")
if __name__ == "__main__":
render_window_watcher = WindowWatcher()
cmds.scriptJob(event=["idle",
pm.windows.Callback(render_window_watcher.check_for_window_open)])
Sorry if the code is not highlighted I dont really know how to format it :/
