Table 27 describes the SetIconImage function:

Example:

...

/* Declares and initiates a Page Object */

GL_Page_TypeDef page1;

Create_PageObj( &page1 );

/* Declares and initiates a Icon Object and add it with specified coordinates to a

Page Object */

GL_PageControls_TypeDef* MyIcon = NewIcon("MyIcon",(GL_uint8_t*)myImage1,90,90,

IconFunc);

AddPageControlObj((uint16_t)((LCD_Width/2)+45),(uint8_t)((LCD_Height/2)+45),MyIcon,

&page1);

...

void IconFunc(void)

{

if (page1.Page_Active == GL_TRUE)

{

GL_uint8_t* ptrBitmap = GL_NULL;

ptrBitmap = (GL_uint8_t*)myImage2;

SetIconImage( &page1, "MyIcon", ptrBitmap, 90, 90);

RefreshPage( &page1 );

}
