|
- bg_color == background_color() |
|
|
|
- widgets == this binary search tree contains every drawable that is in |
|
this window. It is a mapping of each drawable's z-order to a pointer |
|
to said drawable. |
|
- widget_set == a set that contains all the widgets in this window and |
|
want to receive events. |
|
|
|
- mouse_move == this is a set of drawables that are in this window and |
|
want to receive the mouse movement events. |
|
- mouse_wheel == this is a set of drawables that are in this window and |
|
want to receive the mouse wheel events. |
|
- mouse_click == this is a set of drawables that are in this window and |
|
want to receive the mouse click events. |
|
- window_resized == this is a set of drawables that are in this window and |
|
want to receive the window_resized event. |
|
- keyboard == this is a set of drawables that are in this window and |
|
want to receive keyboard events. |
|
- focus == this is a set of drawables that are in this window and |
|
want to receive focus events. |
|
- window_moved == this is a set of drawables that are in this window and |
|
want to receive window move events. |
|
|
|
- lastx == the x coordinate that we last saw the mouse at or -1 if the |
|
mouse is outside this window. |
|
- lasty == the y coordinate that we last saw the mouse at or -1 if the |
|
mouse is outside this window. |
|
|
|
- event_id == a number we use to tag events so we don't end up sending |
|
an event to a drawable more than once. This could happen if one of the |
|
event handlers does something to reset the enumerator while we are |
|
dispatching events (e.g. creating a new widget). |
