How would i get this so i could click anywhere within the grid with this functions?
void CGrid::cellHit(int x, int y, int &row, int &col)
{
//fix it so that we correctly know which item is hit
//you have access to the following member variables
m_rows, m_cols;
m_origin_x, m_origin_y;//left, bottom grid
m_height, m_width;
col = x;
row = y;
}
void CGrid::cellHit(int x, int y, int &row, int &col)
{
//fix it so that we correctly know which item is hit
//you have access to the following member variables
m_rows, m_cols;
m_origin_x, m_origin_y;//left, bottom grid
m_height, m_width;
col = x;
row = y;
}
not much information..
but taking a guess i would say
grid【row】【col】.m_origin_x=x；
grid【row】【col】.m_origin_y=y；
but taking a guess i would say
grid【row】【col】.m_origin_x=x；
grid【row】【col】.m_origin_y=y；
