Toolbars

To attach a toolbar to a window, simply call wind_set with the following parameters:

OBEJECT *tree=rsrc_gaddr(TOOLBAR);

wind_set(window_handle,WF_TOOLBAR,((long)tree & 0xffff0000) >> 16,(long)tree & 0xffff);

When an object which is flagged as 'touchexit' is clicked on, the AES sends a WM_TOOLBAR message to your program, with the window handle in msgbuf[3], the object index in msgbuf[4] and the number of clicks in msgbuf[5]. Note that the object is not automatically set to 'selected'.

To redraw parts of the toolbar, you will need to write a function such as the one below, which uses the new wind_get() flags. The function below will redraw the part of the toolbar indicated by pclipbox.

void redraw_bar(int windowhandle, OBJECT *tree, int obindex, GRECT *pclipbox)
{
 GRECT windbox;
        
 // walk the rectangle list with WF_TOOLBAR as the first rectangle, and WF_NTOOLBAR as the next
 wind_get(windowhandle,WF_FTOOLBAR,&windbox.g_x,&windbox.g_y,&windbox.g_w,&windbox.g_h);

 while (windbox.g_w && windbox.g_h)            // while the rectangle covers something
   {
    if (rc_intersect(pclipbox,&windbox))
        objc_draw(tree,obindex,MAX_DEPTH,windbox.g_x,windbox.g_y,windbox.g_w,windbox.g_h);
    wind_get(windowhandle,WF_NTOOLBAR,&windbox.g_x,&windbox.g_y,&windbox.g_w,&windbox.g_h); 
   }
}
