EvntWindom()

NAME

EvntWindom - GEM events handling.

PROTOTYPAGE

int EvntWindom( int event);

PARAMETRES

event:

bit field of event to handle,

return:

bit field of occured events.

DESCRIPTION

This function is the heart of WinDom. It replaces the AES evnt_multi() function (the EvntMulti() is already used by the Pure C AES bindings).

EvntWindom() is a little bit complex:

• it calls the evnt_multi() function,

• it handles the color palette depending of the topped window or the desktop palette if no topped window,

• it calls the good event function depending the event occured (MU_MESAG, MU_BUTTON, ...),

• window menu window, toolbar, keyboard shortcuts, specific WinDom features are handled. If needed, the AES special features (iconfications, bottom windows, untoppable and modal windows) are emulated,

• some new messages are eventually sent.

EvntWindom() can be parametrized (as evnt_multi()). The parametrization is performed in the gobal variable evnt. Some events return some additional informations. These informations are stored in the evnt variable too. This variable is a C-struct which have the following compostion:

         typedef struct {
           /* parametrization variables
            *****************************/
             /* MU_TIMER parameters - see evnt_timer() */
             int lo_timer, hi_timer;
             /* MU_BUTTON parameters - see evnt_button() */
             int bclick, bmask, bstate;
             /* MU_M1  parameters */
             int m1_flag, m1_x, m1_y, m1_w, m1_h;
             /* MU_M2  parameters */
             int m2_flag, m2_x, m2_y, m2_w, m2_h;
           /* result variables
            ********************/
             /* MU_MESAG result */
             int buff[8];
             /* MU_BUTTON result - see evnt_button()*/
             int mx, my, mbut, mkstate;
             /* MU_KEYBD result - see evnt_keybd() */
             int keybd, nb_click;
     } EVNTvar;
