我在QFormLayout中获取QTreewidget全高度时遇到问题。我在Windows 10上并使用QT 5.7
我尝试的事情:

<?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">

请阅读有关布局的Qt教程。 我在你的ui文件中添加了两个布局和一个spacer。
<?xml version="1.0" encoding="UTF-8"?>
<ui version="4.0">

<widget class="QDialog" name="Dialog">
<property name="geometry">
<rect>

<y>0</y>
<width>489</width>
<height>215</height>
</rect>
</property>
<property name="windowTitle">
<string>Dialog</string>
</property>
<layout class="QHBoxLayout" name="horizontalLayout_2">
