Platform Package reference: Function EwSetStyles()

Description of the function EwSetStyles() available in all Platform Packages for C compatible target systems. This function is intended to be used when integrating the Embedded Wizard created GUI application with the underlying graphics subsystem, graphics hardware or other external GUI applications coexisting on the same system.

Declaration

void EwSetStyles( XStylesSet aStylesSet )

Parameters

aStylesSet

A set containing all desired style members to enable. Or 0 (zero) to disable all styles.

Discussion

The function EwSetStyles() changes the currently selected styles set to the value aStylesSet. To disable all styles pass 0 (zero) in the argument to this function.

This operation corresponds to the modification of the Chora built-in variable styles. Generally, the activation/deactivation of the styles affects the selection of multi-variant constants, resources, classes or autoobjects.
