About GDI object?..

Answer / naviyr

GDI object (is a graphical device object) used to write on a
device context for graphical output.
GDI objects are: Pen, Brush, Font,Line, Rectangle etc.
These objects are created using their corresponding win32
function. For eg, CreatePen, CreatePenIndirect are used to
create a pen object.
After these objects are created they would need to be
selected to the device context before processing using
"SelectObject" function.
GDI objects are not associated with any device context
during its creation. SelectObject function does that
assocaition.
Once an object is selected into the device context it would
be available until the object is destroyed through
DeleteObject or the program exits.
