- XExposeEvent - Expose event structure
-
- SSSSTTTTRRRRUUUUCCCCTTTTUUUURRRREEEESSSS
- The structure for _E_x_p_o_s_e events contains:
-
- typedef struct {
- int type; /* Expose */
- unsigned long serial; /* # of last request processed by server */
- Bool send_event; /* true if this came from a SendEvent request */
- Display *display; /* Display the event was read from */
- Window window;
- int x, y;
- int width, height;
- int count; /* if nonzero, at least this many more */
- } XExposeEvent;
-
- When you receive this event, the structure members are set
- as follows.
-
- The type member is set to the event type constant name that
- uniquely identifies it. For example, when the X server
- reports a _G_r_a_p_h_i_c_s_E_x_p_o_s_e event to a client application, it
- sends an _X_G_r_a_p_h_i_c_s_E_x_p_o_s_e_E_v_e_n_t structure with the type member
- set to _G_r_a_p_h_i_c_s_E_x_p_o_s_e. The display member is set to a
- pointer to the display the event was read on. The
- send_event member is set to _T_r_u_e if the event came from a
- _S_e_n_d_E_v_e_n_t protocol request. The serial member is set from
- the serial number reported in the protocol but expanded from
- the 16-bit least-significant bits to a full 32-bit value.
- The window member is set to the window that is most useful
- to toolkit dispatchers.
-
- The window member is set to the exposed (damaged) window.
- The x and y members are set to the coordinates relative to
- the window's origin and indicate the upper-left corner of
- the rectangle. The width and height members are set to the
- size (extent) of the rectangle. The count member is set to
- the number of _E_x_p_o_s_e events that are to follow. If count is
- zero, no more _E_x_p_o_s_e events follow for this window.
- However, if count is nonzero, at least that number of _E_x_p_o_s_e
- events (and possibly more) follow for this window. Simple
- applications that do not want to optimize redisplay by
- distinguishing between subareas of its window can just
- ignore all _E_x_p_o_s_e events with nonzero counts and perform
- full redisplays on events with zero counts.
