When you add widgets to a layout, the layout process works as follows:

## Custom Widgets In Layouts
teleopanel/layouthtml1_46.txt
* A [ QHBoxLayout ](qhboxlayout.html) lays out widgets in a horizontal row, from left to right (or right to left for right-to-left languages).
teleopanel/layouthtml_28.txt
When you use a layout, you must insert each child both into its parent widget (done in the constructor) and into its layout (typically done with a function called addWidget()). This way, you can give layout parameters for each widget, specifying properties like alignment, stretch, and placement.

If you are making a one-of-a-kind special layout, you can also make a custom widget as described above. Reimplement [ QWidget::resizeEvent ](qwidget.html#resizeEvent) () to calculate the required distribution of sizes and call [ setGeometry ](qwidget.html#setGeometry) () on each child.

* **Execution Dependencies** specify which packages are needed to run code in this package. This is the case when you depend on shared libraries in this package (especially when these packages are declared as (CATKIN_)DEPENDS in _catkin_package()_ in CMake).
teleopanel/packagexml_35.txt
* **Build Tool Dependencies** specify build system tools which this package needs to build itself. Typically the only build tool needed is catkin. In a cross-compilation scenario build tool dependencies are for the architecture on which the compilation is performed.

If the built-in layout classes are not sufficient, you can define your own. You must make a subclass of [ QLayout ](qlayout.html) that handles resizing and size calculations, as well as a subclass of [ QGLayoutIterator ](qglayoutiterator.html) to iterate over your layout class.
