My sample ui

<?xml version="1.0" encoding="UTF-8"?>
<ui version="4.0">
 <class>MyDialog</class>
 <widget class="QDialog" name="MyDialog">
  <property name="geometry">
   <rect>

    </rect>
   </property>
  </widget>
  <widget class="QListView" name="listView">
   <property name="geometry">

     <x>210</x>
     <y>0</y>
     <width>191</width>

   </property>
  </widget>
 </widget>
 <resources/>
 <connections>
  <connection>
   <sender>buttonBox</sender>

  </connection>
 </connections>
</ui>

How :

1. I want my controls change size depend on dialog size
2. Tree and Listview should be possible change size by mouse

Hi,

Use layouts to position your widgets. They will also take care of resizing your widgets when you change your dialog size.

If you need some manual control, then QSplitter might be what you are looking for.

I try QHBoxLayout but not works.
QSplitter I can't find in Designer menu.

What does not work? How do you use it?

To use a splitter select both widgets which you want to separate with the splitter and then select "Lay Out Horizontaly in Splitter" (or Vertically) in top tool bar.
