| void vgui_soview::attach | ( | vgui_observer * | o | ) | [inherited] |
Attach given observer to this soview.

| float vgui_soview2D_infinite_line::distance_squared | ( | float | x, |

Definition at line 230 of file vgui_soview2D.cxx.
| void vgui_soview2D_infinite_line::draw | ( | ) | const [virtual] |
Render this 2D infinite line on the display.
Implements vgui_soview.
Definition at line 225 of file vgui_soview2D.cxx.
| void vgui_soview::draw_select | ( | ) | const [virtual, inherited] |
Render this soview for selection purposes.
By default, this will call draw(). However, some objects take time to draw, especially in GL_SELECT mode. The routine allows such objects to render a simplified version for the selection process. Note that during selection, the object is not rendered on screen. The "rendering" is used by OpenGL internals to determine if the object is in the selection region (e.g. area around mouse pointer).
Reimplemented in vgui_soview2D_group, and vgui_soview2D_point.
