Add support of refreshing time in widgets
Issue #260
new
Implementation reason
Actually it is not possible to update progress bar value in asynchronous mode. It is only possible by calling oC_WidgetScreen_SetValue
but to do it, we have to run another thread.
Generic Description
The goal of the task is to add possibility to set a handler in the widget screen module, that allows for update value in some other way, for example by requesting a value in each 500 ms.
// Type for storing pointer to the function that should be called when widget is redrawn and value for the widget has to be updated
typedef oC_WidgetScreen_Value_t (*oC_WidgetScreen_GetWidgetValueHandler_t)( oC_WidgetScreen_t Screen, oC_WidgetScreen_UserContext_t Context, oC_WidgetScreen_WidgetIndex_t Index );
typedef struct
{
oC_WidgetScreen_WidgetType_t Type;
oC_Pixel_Position_t Position;
oC_Pixel_ResolutionUInt_t Height;
oC_Pixel_ResolutionUInt_t Width;
oC_WidgetScreen_ZPosition_t ZPosition;
const oC_WidgetScreen_Palette_t * Palette;
const oC_WidgetScreen_DrawStyle_t * DrawStyle;
oC_DefaultPathString_t ImagePath;
oC_WidgetScreen_WidgetHandlers_t Handlers;
oC_WidgetScreen_GetWidgetValueHandler_t GetValueHandler; // Called when value should be updated
} oC_WidgetScreen_WidgetDefinition_t;
typedef struct
{
oC_Pixel_Position_t Position;
oC_Pixel_ResolutionUInt_t Height;
oC_Pixel_ResolutionUInt_t Width;
oC_Color_t BackgroundColor;
oC_ColorFormat_t ColorFormat;
oC_WidgetScreen_ScreenHandler_t PrepareHandler;
oC_WidgetScreen_ScreenHandler_t Handler;
const oC_WidgetScreen_WidgetDefinition_t * WidgetsDefinitions;
uint32_t NumberOfWidgetsDefinitions;
oC_Time_t RefreshPeriod; // Maximum time after which the screen should be refreshed and redrawn
} oC_WidgetScreen_ScreenDefinition_t;
