Ahh, thanks. It sounds like that might have fixed it. And this is the class I
made:
class MyTable : public Fl_Table
{
public:
MyTable( int x, int y, int w, int h, const char* l = NULL ) : Fl_Table(
x, y, w, h, l )
{
col_resize( 1 );
row_resize( 1 );
};
~MyTable() {};
void cell_dimensions( int r, int c, int &X, int &Y, int &W, int &H )
{
find_cell( CONTEXT_TABLE, r, c, X, Y, W, H );
};
protected:
void draw_cell( TableContext context, int R, int C, int X, int Y, int
W, int H )
{
if ( context == CONTEXT_STARTPAGE )
fl_font( FL_HELVETICA, 12 );
else if ( context == CONTEXT_RC_RESIZE )
{
int X, Y, W, H, index = 0;
for ( int r = 0; r<rows(); r++ )
{
for ( int c = 0; c<cols(); c++ )
{
if ( index >= children() )
break;
find_cell( CONTEXT_TABLE, r, c, X, Y,
W, H );
child( index++ )->resize( X,Y,W,H );
}
}
// tell group children resized
init_sizes();
}
};
};
Is there any reason why find_cell isn't public?
