    <p><strong>Updated: to make it much clearer.</strong></p> <p>In the following code snippets, making use of Maya widgets through <code>pymel</code>, there is an error highlight on the right of Command Line.</p> <pre><code>import pymel.core as pm def raiseError(): pm.select("ooxx") # ooxx doesn't exist print "Something after the exception." class pymelWindow(object): def __init__(self): self.mainWin = pm.window("test") with self.mainWin: mainForm = pm.formLayout() with mainForm: btn = pm.button(label='show error',command=pm.Callback(raiseError)) mainForm.redistribute() def show(self): self.mainWin.show() win = pymelWindow() win.show() </code></pre> <p>Here attached is an snapshot of Maya 2011 (the same issue in Maya2014) with an error highlight (<strong>in red</strong>).</p> <p><img src="https://i.stack.imgur.com/FKV2g.jpg" alt="Maya with error highlight to the right of Command Line."></p> <p>and here is the Stack Trace:</p> <pre><code># Error: Maya Node does not exist: u'ooxx' # Traceback (most recent call last): # File "/usr/autodesk/maya2014-x64/lib/python2.7/site-packages/pymel/internal/factories.py", line 778, in callback # res = origCallback( *newargs ) # File "/usr/autodesk/maya2014-x64/lib/python2.7/site-packages/pymel/internal/factories.py", line 701, in __call__ # return self.func(*self.args, **self.kwargs) # File "/dept/rdworks/drake/Desktop/pyqt_issues/testPyQtSpitError.py", line 119, in raiseError # pm.select("ooxx") # File "/usr/autodesk/maya2014-x64/lib/python2.7/site-packages/pymel/core/general.py", line 151, in select # raise TypeError, msg # MayaNodeError: Maya Node does not exist: u'ooxx' # </code></pre> <p>However, when I switch to use PyQt/PySide for widgets with the following code snippets, there is no any visible <em>error highlight to the right of Command Line</em>! Does anyone know how to make PyQt/PySide version have the same GUI behaviours?</p> <pre><code>import pymel.core as pm from PyQt4 import QtGui def raiseError(): pm.select("ooxx") # ooxx doesn't exist print "Something after the exception." class pyQtWindow(QtGui.QMainWindow): def __init__(self, parent = None): # init our ui using the MayaWindow as parent super(pyQtWindow, self).__init__(parent) self.centralWidget = QtGui.QWidget(self) self.setCentralWidget(self.centralWidget) self.centralLayout = QtGui.QVBoxLayout() self.centralWidget.setLayout(self.centralLayout) self.errorBtn = QtGui.QPushButton('show error') self.errorBtn.clicked.connect(raiseError) self.centralLayout.addWidget(self.errorBtn) win = pyQtWindow() win.show() </code></pre> <p><img src="https://i.stack.imgur.com/1YNKl.jpg" alt="Maya without error highlight to the right of Command Line!"></p> <pre><code># Traceback (most recent call last): # File "/usr/autodesk/maya2014-x64/lib/python2.7/site-packages/pymel/internal/factories.py", line 701, in __call__ # return self.func(*self.args, **self.kwargs) # File "/dept/rdworks/drake/Desktop/pyqt_issues/testPyQtSpitError.py", line 119, in raiseError # pm.select("ooxx") # File "/usr/autodesk/maya2014-x64/lib/python2.7/site-packages/pymel/core/general.py", line 151, in select # raise TypeError, msg # pymel.core.general.MayaNodeError: Maya Node does not exist: u'ooxx' </code></pre>

    3. CO@BleedingFingers I'm sure there is nothing printed after the exception. The testing is just that simple in question without any further stuff.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
