Yea there are a few problems in your code, so I can see why it wasn't
working correctly.
Here is a modified version:
## No globals# camLs = []
class orientCameraUI(QDialog):
def __init__(self, parent=None):
super(orientCameraUI, self).__init__(parent)
# You have a class, so you should store state in the class
self.__camLs = []
self.setMinimumWidth(300)
self.setMaximumHeight(80)
self._initUI()
self._camMenu()
# self.createConnections()
def _initUI(self):
...
## Get rid of this. The QPushButton doesn't have aboutToShow()
# def createConnections(self):
# self.connect(self.setCameraBtn, SIGNAL('aboutToShow()'),
self._updateMenu)
def _camMenu(self):
menu = QMenu("menu", self.setCameraBtn)
self.setCameraBtn.setMenu(menu)
menu.aboutToShow.connect(self._updateMenu)
menu.triggered.connect(self._camSelected)
def _camSelected(self, action):
self.currentCamTxt.setText(action.text())
def _updateMenu(self):
## You were creating a brand new menu and clearing it
## each time, instead of clearing the one already set
## on the QPushButton. So nothing was really changing.
# menu = QMenu("menu", self.setCameraBtn)
menu = self.setCameraBtn.menu()
menu.clear()
cams = cmds.listRelatives(cmds.ls(cameras=True), parent=True)
if not cams:
return
allCams = [c for c in cams if not cmds.camera(c, q=True,
startupCamera=True)]
self.__camLs = allCams
if not allCams:
return
for item in camLs:
menu.addAction(item)
Some points about it:
- Get rid of the global list. You can just use an instance attribute if
you want to separately track the camera names
- You were duplicating code and only updating a new temporary QMenu that
you are actually leaking on every update. You never actually updated the
menu set on the button
- Just set up the empty menu once in your init. Then your aboutToShow()
can rebuild that menu every single time.
