Description

Gets the collapsed state of the branches from top to bottom in the control

Gets the collapsed state of given row

Syntax

int GetCollapsed( vector<byte> & vn, bool bOnlyTopLevelIsBranch = true )

int GetCollapsed( int nRow )

Parameters

vn

[output] contains 1(0) for each collapsed(expanded) branch

bOnlyTopLevelIsBranch

[input] when true, states of only consecutive top level branches are returned, otherwise states of all branches of all levels from top to bottom are returned.

nRow

[input]0-offset row index

Return

-1 if not applicable, otherwise return number of branches

-1 if not applicable, otherwise 1 = collapsed, 0 = expended
