QFormLayout does not expand widget full height to maximum widget height

StormeNet

I have an issue with getting a QTreewidget full height inside a QFormLayout. I'm on Windows 10 and use QT 5.7

Things I tried:

all possible Vertical policy's without success.
Change the FieldGrowthPolicy of the layout to AllNonFixedFieldsGrow
Use another widget, all fail to make this work

That's all the options I found to possibly make this work.

Here's what I try to achieve:

Here's my ui file:

<?xml version="1.0" encoding="UTF-8"?>
<ui version="4.0">
 <class>Dialog</class>
 <widget class="QDialog" name="Dialog">
  <property name="geometry">
   <rect>
    <x>0</x>
    <y>0</y>
    <width>760</width>
    <height>747</height>
   </rect>
  </property>
  <property name="windowTitle">
   <string>Dialog</string>
  </property>
  <layout class="QFormLayout" name="formLayout">
   <item row="0" column="0">
    <widget class="QLabel" name="label">
     <property name="text">
      <string>Please grow the treeview:</string>
     </property>
    </widget>
   </item>
   <item row="0" column="1">
    <widget class="QTreeWidget" name="treeWidget">
     <property name="sizePolicy">
      <sizepolicy hsizetype="Expanding" vsizetype="MinimumExpanding">
       <horstretch>0</horstretch>
       <verstretch>0</verstretch>
      </sizepolicy>
     </property>
     <column>
      <property name="text">
       <string notr="true">1</string>
      </property>
     </column>
    </widget>
   </item>
  </layout>
 </widget>
 <resources/>
 <connections/>
</ui>

I think QFormLayout inserts a spacer at the bottom by default. Convert it to a QGridLayout to have the desired result

@VRonin Okay, that works better, thanks.
However, now the labels are center aligned vertically and the only way to change this seems to be in the AddWidget function.
Is there a way to do this in Qt Designer? Can't seem to select a QGridLayout's cell to set properties of that cell.

Just click on the label and set the alignment property

You should set the object in the last row of formlayout (see QTreewidget), its vertical expanding factor should not be 0.
