Peripheral and Interface Components
Verification and testing
The GUIPoll component has been tested as part of the PhoneSkin example platform, confirming
that the GUI continues to be refreshed even when the simulation is stopped.
Performance
The GUIPoll component is not expected to significantly affect the performance of a PV system.
Library dependencies
The GUIPoll component has no dependencies on external libraries.
5.5.5 C++ classes
This section describes the C++ classes and structures that are made available to you through the
Visualisation library. To make use of these classes, you must ensure that your LISA component
begins with:
includes
{
#include “components/Visualisation.h”
}
Classes and structures described in this section are:
• Class Visualisation
• Class VisRegion on page 5-154
• Class VisPushButtonRegion : public VisRegion on page 5-154
• Class VisRenderRegion : public VisRegion on page 5-154
• Struct VisRasterLayout on page 5-155
• Struct VisPixelFormat on page 5-156.
Class Visualisation
The Visualisation class provides access to the API for creating a custom LISA visualization
component.
A component obtains an instance of this class by calling the global function
createVisualisation(). The component can then use this instance to control the size and layout
of the visualization window.
The Visualisation library is currently implemented using the Simple DirectMedia Layer (SDL)
cross-platform rendering library.
Global functions
Visualisation *createVisualisation()
This generates an instance of the Visualisation library. You can only call this
function once, as SDL only supports opening a single display window.
Class Visualisation
~Visualisation()
Destructor for the Visualisation library. You must only call this method when your
simulation is shutting down, after all allocated resources (VisRenderRegions,
VisPushButtonRegions, VisBitmaps) have been deleted.
