The GDI Sprite is a rectangular display that can display any OpenGL user code.
It can be used to represent any specific gauge or graphic that is not supported by the actual given Sprites.
getWidth(): return the width of the GDI (horizontal), same as db->width
getHeight(): return the height of the GDI (vertical), same as db->height
getCenter(): return a Coord2D for the center of the GDI
On the HMI grid, add a GDI:
or
In the Runtime panel, put the following code:
|
ogl->drawCircle(db->width/2,db->height/2,10);
|
This will draw a circle of 10 pixels centered in the middle of the GDI
