BroTools Snippets #03 – PySide context menu for QLineEdit and other elements…

Well, some time ago I decided to go with PySide code for all my UIs instead of native maya.cmds functions for menu-building. I was attracted to the freedom in creating and styling of those menus, and the fact that Jeremy Ernst did a lot of menus with PySide. And another fact that knowing PySide I can not only write UIs for maya, but also for different standalone python tools. Which is cool. But if you just need a menu – go with cmds. Don’t bother with PySide.

Anyway, with that said, I still prefer to use PySide. And recently I was banging my head against the wall, trying to add a simple context menu to QLineEdit. To allow pasting some preset text into QLineEdit, for BroSelector tool.

And Finally, it worked!

Here is the full code related to it. I skip imports and window creation. Just the relevant stuff.

 

#Creating the actual QLineEdit. I use from QtGui import *, so I don't need to write QtGui.QLineEdit, just QLineEdit, mind that.
self.type = QLineEdit("transform")
# Adding context menu to line edit
# Creating action. Make as many as you like
self.actionHello = QAction(self)
self.actionHello.setText("Hello")
self.actionHello.triggered.connect(yourFunctionHere)

# Creating Menu
self.menu = QMenu(self)
# Adding action to menu. Add as many as you like
self.menu.addAction(self.actionHello)

# First we need to change our element's Context Menu Policy to Custom.
self.type.setContextMenuPolicy(Qt.CustomContextMenu)

# Now we catch basically the right-click event, the customContextMenuRequested event, and assing our own handler (function) for it.
self.type.customContextMenuRequested.connect(self.contextMenuRequested)

#And here goes the handler function.
def contextMenuRequested(self, point):
    # the point variable (which you can call whatever you like actually) is passed to this function as first arg, so we can use it in the next line.
    self.menu.exec_(self.type.mapToGlobal(point))

And thats it. YAY! Saving it here, so I won’t lose it, and in case it is useful to someone.

BroTools Snippets #02

Saving another couple of clicks in routine work, simple script to select joints influencing skinned mesh. Could not find a 1-click solution for this in Maya. Maybe I just missed something? Anyway, maybe this will be useful for someone. Will just leave it here.

It will select joints influencing all shapes of all selected objects.

In a form that can be used in a shelf:

import maya.cmds as cmds
def selectInfluenceJoints (meshes=None):
    if meshes == None:
        meshes = cmds.ls(sl=1)
    if not isinstance(meshes, list):
        meshes = [meshes]
    cmds.select (cl=True)

    for mesh in meshes:
        shapes = cmds.listRelatives(mesh, c=True, s=True)
        for shape in shapes:
            sk = cmds.listConnections(shape, et=True, t='skinCluster')
            if sk != None:
                for s in sk:
                    influences = cmds.skinCluster (s, q=True, inf=True)
                    cmds.select (influences, add=True)
selectInfluenceJoints()
