Layouts

Definition

Layouts are defined in ".xeyegui" files in xml syntax. Minimal example of the content of such a file is given below:

<?xml version="1.0"?>
<layout>
  <circlebutton></circlebutton>
</layout>

The outer xml element must be "layout" and there must be exactly one inner element. This inner element could be a grid with multiple elements or only one as described in the example above. For a complete list of available elements take a look at Elements. The layout element in xml can have following attributes:

Attribute	Type	Description
stylesheet	string	Relative path to used stylesheet

More about stylesheets in Styling.

Usage

Adding a layout to a existing GUI is done by calling the addLayout function of the interface with the pointer to the GUI and the relative path to the xml file with the layout.

eyegui::Layout* pLayout = eyegui::addLayout(pGUI, "HelloLayout.xeyegui");

If any parsing errors or warnings appear, the previously defined callbacks are called with a message string describing the problem.
