Description

SetSelection will be used to do multiple selection on a given Grid

Syntax

BOOL SetSelection( vector<int> & vR1, vector<int> & vC1 = NULL, vector<int> & vR2 = NULL, vector<int> & vC2 = NULL, BOOL bData = true )

Parameters

vR1: vector of indices of the first rows in the selection
vC1: [optional] vector of indices of the first columns in the selection
vR2: [optional] vector of indices of the last rows in the selection
vC2: [optional] vector of indices of the last columns in the selection
bData: decides whether the selection would be in data region or Labels region in worksheet

Return

True for success; otherwise false.

Examples

EX1

// example select all rows in a worksheet where
// col(1) is between 0.2 and 0.6
// To test, fill col(1) with uniform random numbers
//col(1)=uniform(1000)
void Grid_SetSelection_ex1(string strPre = "range a=1", string strCond = "a>=0.2 && a<=0.6")
{
    Worksheet wks("Book1");
    vector<uint> vnRowIndices;
    int nn = wks.SelectRows(strCond, vnRowIndices, 0, -1, -1, strPre);
    if(nn == 0)
        out_str("no matching row");
    else
    {
       Grid gg;
       if(gg.Attach(wks))
       {
               vector<int> vnRows;
               vnRows = vnRowIndices;
            gg.SetSelection(vnRows);
            out_int("Number of rows =", nn);
       }
    }
}

Remark

SetSelection will be used to do multiple selection on a given Grid. The optional args maybe skipped under the following three situations

SetSelection(vR1); // Full rows selected;

SetSelection(vR1, vC1);// individual cells selected

SetSelection(vR1, vC1, vR2, vC2);// partial cols selected;
