Protected Functions inherited from evab::ElementBase¶

See evab::ElementBase

Type	Name
virtual void	drawer (Screen * aScreen, Coor aPos, Coor aSize, unsigned char aIsFocused) = 0 Pure virtual method for drawing the element.
virtual void	freezer () Virtual method for freezing the element.
bool	isFrozen () Checks if the element is currently freezed.
void	redraw () Redraws the element on the current screen.

Detailed Description¶

This element displays an animated pictogram where the animation speed can be adjusted by the user. The animation cycles through available pictograms at a speed determined by the current value.

The element uses the eva::Tickable system for periodic updates. The speed value ranges from 0 (stopped) to tMaxSpeed (maximum animation speed). Animation is automatically paused when the element is hidden and resumed when it becomes visible again.

Redraws occur only on timer ticks to maintain consistent animation timing.

Template parameters:

TAlbum Album class providing pictogram data and count
tMaxSpeed Maximum speed value (must be > 0)

aValue Initial speed value (0 to tMaxSpeed)

function Select¶

Sets the animation speed.

inline void evab::InputAnimationPx::Select (
    unsigned char aValue
)

Parameters:

aValue Speed value (0 = stopped, 1..tMaxSpeed = animation speed)

function Selected¶

Gets the current speed value.

inline unsigned char evab::InputAnimationPx::Selected () const

Returns:

Current speed value (0 to tMaxSpeed)

function ~InputAnimationPx¶

Destructor - removes from Tickable list.

function drawer¶

Draws the animation on screen.

inline virtual void evab::InputAnimationPx::drawer (
    Screen * aScreen,
    Coor aPos,
    Coor aSize,
    unsigned char aIsFocused
) override

Resumes animation if element is visible and speed > 0.
