DefaultDrawingsLineWidthRepo

Stores information about the current global line width / text size value for new drawings, provides data about the minimum (minLineWidth) and maximum (maxLineWidth) line length / text size.

Default implementation:

/**
* Default implementation of [com.devexperts.dxcharts.lib.data.repo.DrawingsLineWidthRepo].
*
* This class provides a default implementation of the [DrawingsLineWidthRepo] interface.
*
* @property getLineWidthCallback Callback function to get the line width for new drawings.
* @property setLineWidthCallback Callback function to set the line width for new drawings.
* @property minLineWidth Minimum line width. Default value is 1.
* @property maxLineWidth Maximum line width. Default value is 5.
*
* @see DrawingsLineWidthRepo
