Function
void GFX_GOL_MeterDecrement(
GFX_GOL_METER *pObject,
uint16_t delta)
1.6.2.1.7.11 GFX_GOL_MeterDraw Function
This function renders the object on the screen based on the current state of the object.
File
gfx_gol_meter.h
Syntax
GFX_STATUS GFX_GOL_MeterDraw(void * pObject);
Returns
GFX_STATUS_SUCCESS - When the object rendering is finished. GFX_STATUS_FAILURE - When the object rendering is
not yet finished. Application needs to call this rendering function again to continue the rendering.
Description
This function renders the object on the screen based on the current state of the object. Location of the object is determined
by the left, top, right and bottom parameters. The colors used are dependent on the state of the object. The font used is
determined by the style scheme set.
When rendering objects of the same type, each object must be rendered completely before the rendering of the next object
is started. This is to avoid incomplete object rendering.
Normally, application will just call GFX_GOL_ObjectListDraw() to allow the Graphics Library to manage all object rendering.
See GFX_GOL_ObjectListDraw() for more information on object rendering.
Preconditions
Object must exist in memory.
Example
None.
Parameters
Parameters Description
pObject Pointer to the object.
Function
GFX_STATUS GFX_GOL_MeterDraw(void *pObject)
1.6.2.1.7.12 GFX_GOL_MeterIncrement Function
This function increments the meter value by the delta value set.
File
gfx_gol_meter.h
Syntax
void GFX_GOL_MeterIncrement(GFX_GOL_METER * pObject, uint16_t delta);
Returns
None.
