Solution________________________________________________________________________
This sample code creates time out with the Photon PtAlert function.
Use PtTimer to destroy the Widget.
Example:
/* Standard headers */
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <string.h>
/* Local headers */
#include "ablibs.h"
#include "abimport.h"
#include "proto.h"
static PtWidget_t *FrontChild;
int BtnCb( PtWidget_t *widget, ApInfo_t *apinfo, PtCallbackInfo_t *cbinfo ) {
/* eliminate 'unreferenced' warnings */
widget = widget, apinfo = apinfo, cbinfo = cbinfo;
return Pt_CONTINUE;
}
int SetupCb( PtWidget_t *link_instance, ApInfo_t *apinfo, PtCallbackInfo_t *cbinfo ) {
char const *buttons[3] = { "Yes", "No", "Maybe" };
int btn;
/* eliminate 'unreferenced' warnings */
link_instance = link_instance, apinfo = apinfo, cbinfo = cbinfo;
/* Remember which widget (in base window) was originally in front */
FrontChild = PtWidgetChildFront( ABW_base );
switch ( btn = PtAlert( ABW_base, NULL, "title", NULL, "message", NULL, 3, buttons, NULL, 3, 2, Pt_CENTER | Pt_MODAL | Pt_RELATIVE ) ) {
case -1: printf( "Timeout!\n" ); break;
case 1:
case 2:
case 3: printf( "Button #%d: '%s'\n", btn, buttons[btn-1] ); break;
default: printf( "Unexpected: %d\n", btn ); break;
}
FrontChild = NULL;
return Pt_CONTINUE;
}
int TmrCb( PtWidget_t *widget, ApInfo_t *apinfo, PtCallbackInfo_t *cbinfo ) {
/* eliminate 'unreferenced' warnings */
widget = widget, apinfo = apinfo, cbinfo = cbinfo;
if ( ( NULL != ( widget = PtWidgetChildFront( ABW_base ) ) ) && ( widget != FrontChild ) ) {
PtDestroyWidget( widget );
FrontChild = NULL;
}
return Pt_CONTINUE;
}
