Qt textEdit Window size

KeithSloan

Already tried

layout.addWidget(self.textEdit,2)
layout.addWidget(self.textMsg,1)

But no change.

Think as its a textEdit window there is a scrollArea attached and if I print out its height it is 480 pixels which what I am seeing, but no idea how to influence, tried changing various options on setSizePolicy but again no change.

@KeithSloan said in Qt textEdit Window size:

This is not clear.

Can you provide the full layout setup code ?

KeithSloan

The following code is in a FreeCAD workbench. I have no control over parent window, just want to size to what it makes available
which varies on how the user controls various windows.

class AddSCADWidget(QtGui.QWidget):
    def __init__(self,*args):
        QtGui.QWidget.__init__(self,*args)
        # Main text area
        self.textEdit=QtGui.QTextEdit()
        self.textEdit.setAcceptRichText(False)
        # Following line Made no difference
        self.textEdit.setMaximumHeight(4096)
        # Following made no difference also tried QSizePolicyExpanding
        self.textEdit.setSizePolicy(QtGui.QSizePolicy.Expanding, \
                   QtGui.QSizePolicy.MinimumExpanding)
        print(self.textEdit.sizePolicy())
        print(self.textEdit.sizeHint())
        print(self.textEdit.viewport())
        vp = self.textEdit.viewport()
        print(vp.maximumHeight())
        print(vp.height())
        print(vp.sizeHint())
        # following did not make any difference
        vp.setSizePolicy(QtGui.QSizePolicy.Expanding, \
                   QtGui.QSizePolicy.Expanding)
        print(vp.sizePolicy()
        # Message Area
        self.textMsg=QtGui.QPlainTextEdit()
        self.textMsg.setReadOnly(True)
        h = int(2.5 * self.textMsg.fontMetrics().height())
        self.textMsg.setMaximumHeight(h)
        self.textMsg.resize(self.textMsg.width(),h)
        self.buttonadd = QtGui.QPushButton(translate('OpenSCAD','Add'))
        self.buttonclear = QtGui.QPushButton(translate('OpenSCAD','Clear'))
        self.buttonload = QtGui.QPushButton(translate('OpenSCAD','Load'))
        self.buttonsave = QtGui.QPushButton(translate('OpenSCAD','Save'))
        self.buttonrefresh = QtGui.QPushButton(translate('OpenSCAD','Refresh'))
        self.checkboxmesh = QtGui.QCheckBox(translate('OpenSCAD','as Mesh'))
        layouth=QtGui.QHBoxLayout()
        layouth.addWidget(self.buttonadd)
        layouth.addWidget(self.buttonload)
        layouth.addWidget(self.buttonsave)
        layouth.addWidget(self.buttonrefresh)
        layouth.addWidget(self.buttonclear)
        layout= QtGui.QVBoxLayout()
        layout.addLayout(layouth)
        layout.addWidget(self.checkboxmesh)
        #layout.addWidget(self.textEdit, 6)
        #layout.addWidget(self.textMsg, 1)
        layout.addWidget(self.textEdit)
        layout.addWidget(self.textMsg)
        layout.setStretch(0,0)
        layout.setStretch(1,0)
        layout.setStretch(2,1)
        layout.setStretch(3,0)
        self.setLayout(layout)
        self.setWindowTitle(translate('OpenSCAD','Add OpenSCAD Element'))
        self.textEdit.setText(u'cube();')
        self.buttonclear.clicked.connect(self.textEdit.clear)

What do you get if you use just this:

class AddSCADWidget(QtGui.QWidget):
    def __init__(self,*args):
        QtGui.QWidget.__init__(self,*args)
        # Main text area
        self.textEdit=QtGui.QTextEdit()
        # Message Area
        self.textMsg=QtGui.QPlainTextEdit()
        self.textMsg.setReadOnly(True)
        h = int(2.5 * self.textMsg.fontMetrics().height())
        self.textMsg.setMaximumHeight(h)
  
        layout= QtGui.QVBoxLayout(self)
        layout.addWidget(self.textEdit, 2)
        layout.addWidget(self.textMsg, 1)

SGaist

It looks like you only have access to half a widget ?
That's strange, what if you add self.textEdit.setMinimumHeight(4096) ?

KeithSloan

Setting minimumHeight(4096) ( And removing message Window ) still does not expand the the textEdit![alt text]( image url)

SGaist

This is getting stranger and stranger... what if you use setFixedSize ?

KeithSloan

@SGaist My Bad minimumHeight gave me

So I have to some how get the parent window size and calculate the size? Or is there a better way?

SGaist

You shouldn't need to do that.

How are you integrating your code with FreeCAD ?

KeithSloan

It is a FreeCAD workbench so it exists in a subdirectory of Mod in the FreeCAD file structure and as FreeCAD finds a InitGui.py and Init.py file it gets invoked. When the user selects the workbench in this case OpenSCAD it gets started, which registers a number of icons. Press on one of these icons invokes code that creates the boxes in one of the FreeCAD windows, the window can vary in size depending on users monitor, whether is has the Combo View panel displayed and can adjust the size of the Combo window.

KeithSloan

class AddSCADTask:
    def __init__(self):
        self.form = AddSCADWidget()

class AddSCADWidget(QtGui.QWidget):
    def __init__(self,*args):
        QtGui.QWidget.__init__(self,*args)
        # Main text area
        self.textEdit=QtGui.QTextEdit()
        .... etc ...

class AddOpenSCADElement:
    def IsActive(self):
        return not FreeCADGui.Control.activeDialog()

    def Activated(self):
        panel = AddSCADTask()
        FreeCADGui.Control.showDialog(panel)

KeithSloan

Okay in AddSCADTask I added a print(dir(self.form) and got

Does that help at all?

Sorry don't know how to edit this so its not all on one line.

SGaist

Is there a documentation that describes the process to do that task ? I think you might be missing some minor details to get your widget rendered correctly.
