Couple of Qt Questions.

[keithsloan52]

I am trying to control the size of a LineEdit box

I am trying

Code: Select all

self.value = QtGui.QLineEdit()
self.value.setMaxLength = len
self.value.setGeometry(QtCore.QRect(0,0,10,5))

But the setGeometry does not seem to have any effect.

I would also like to drive a FocusOutEvent on when the mouse moves outside of the dialog
the c++ doc has

Code: Select all

void QLineEdit::focusOutEvent(QFocusEvent *e)

But how do I do it in python

I tried adding to the class that defines the task and to. the panel widget

Code: Select all

       def focueOutEvent(self, event) :
              print('Went out of focus')

But did not seem to be driven.

setMaxLength is a function, not an attribute.
Also geometry is quite complex as real effects mainly depend on SizePolicy.

Did you try without making a typo in the function name?

Changed it but still no effect on the size of the box. Think MaxLength applies to amount of
text that can be entered. setGeometry did not seem to work.
added a function

Code: Select all

      def sizeHint(self) :
           return(Qtcore.QSize(10,5))

But that did not help either

Yes, cut and pasted from code this time

Code: Select all

def focusOutEvent(self, event) :
        print('Out of Focus')

Can you share full code?

[keithsloan52]

Okay by reading the docs worked out that I needed a leaveEvent rather than a focusOutEvent .

Which gets driven when I Ieave the Task panel, but if I try closeDialog it crashed FreeCAD

Code: Select all

def leaveEvent(self, event) :
        print('Leave Event')
        FreeCADGui.Control.closeDialog()

Is there a way to close the panel from one of its events?

Widget code

Code: Select all

class oField(QtGui.QWidget) :
    def __init__(self,label,len, value,parent=None) :
        super(oField, self).__init__(parent)
        self.label = QtGui.QLabel(label)
        self.value = QtGui.QLineEdit()
        self.value.setMaxLength(len)
        self.value.setGeometry(QtCore.QRect(0,0,10,5))
        self.value.setReadOnly(True)
        self.value.setText(value)
        self.label.setBuddy(self.value)
        layout = QtGui.QHBoxLayout()
        layout.addWidget(self.label)
        layout.addWidget(self.value)
        self.setLayout(layout)

    def sizeHint(self) :
        return(QtCore.QSize(10,5))

I'm with a mobile now but something like

Code: Select all

QtCore.QMetaObject.invokeMethod(Gui.Control, 'closeDialog', QtCore.Qt.QueuedConnection)

Had to change the Gui.Control to FreeCADGui.Control to get further but then got

Hmm IIRC I had this in C++ too but I don't think we can qobject_cast in Python. I'll eventually have a look at this, but in between maybe the dirty method may work

Code: Select all

QtCore.QTimer.singleShot(0, FreeCADGui.Control, SLOT('closeDialog()'))

Not urgent but would be good to have a vanilla solution
