BoxProgress

getColor

virtual colortype getColor()const

Gets the color of the Box.

Returns:

The color.

See also:

setAlpha

virtual void setAlpha(uint8_tnewAlpha)

Sets the opacity (alpha value).

This can be used to fade it away by gradually decreasing the alpha value from 255 (solid) to 0 (invisible).

Parameters:
newAlphaThe new alpha value. 255=solid, 0=invisible.
Note

The user code must call invalidate() in order to update the display.

See also:

Reimplements: touchgfx::AbstractProgressIndicator::setAlpha

setColor

virtual void setColor(colortypecolor)

Sets the color of the Box.

Parameters:
colorThe color.
See also:

setProgressIndicatorPosition

virtual void setProgressIndicatorPosition(int16_tx ,
int16_ty ,
int16_twidth ,
int16_theight
)

Sets the position and dimensions of the actual progress indicator relative to the background image.

Parameters:
xThe x coordinate.
yThe y coordinate.
widthThe width of the box progress indicator.
heightThe height of the box progress indicator.
See also:

Reimplements: touchgfx::AbstractProgressIndicator::setProgressIndicatorPosition

setValue

virtual void setValue(intvalue)

Sets the current value in the range (min..max) set by setRange().

Values lower than min are mapped to min, values higher than max are mapped to max. If a callback function has been set using setValueSetAction, that callback will be called (unless the new value is the same as the current value).

Parameters:
valueThe value.
Note

if value is equal to the current value, nothing happens, and the callback will not be called.
