xtd::forms::style_sheets::length xtd::forms::style_sheets::lengths::all ( ) const

noexcept

Gets the xtd::forms::style_sheets::lengths value for all the edges.

Returns

The xtd::forms::style_sheets::lengths, in pixels, for all edges if the same; otherwise, -1.

Remarks

When retrieving this property, if all the edges use the same xtd::forms::style_sheets::lengths value, then this common value is returned. Otherwise, -1 is returned to indicate that all the xtd::forms::style_sheets::lengths values are not equal.
