Overview

This example shows how to get list of System alarms in Qt Maemo application. There is now direct Qt classes for this operation - so using GTK functions.

Project .pro file

// Maemo specific config
maemo5 {
LIBS += libalarm.so
}

Packing in DEB - control file

// in source section add for Build-depends line
libalarm-dev

Header

#include <time.h>
#include <alarmd/alarm_dbus.h>
#include <alarmd/libalarm.h>

Source

// get the reference to QComboBox for filling
void SampleWidget::fillAlarmList(QComboBox* &aBox)
{
// clear the list
aBox->clear();
 
cookie_t *list, *iter; // cookie_t - alarm cookies from GTK
time_t now; // time_t structure from GTK
 
// set number of hours to search alarms
int timeFrame = 96;
 
now = time(NULL);
// get list of alarms
list = alarmd_event_query(now, now + timeFrame*3600, ALARM_EVENT_DISABLED, 0, NULL);
 
if (list[0] != (cookie_t) 0) {
// iterate through alarm list
for (iter = list; *iter != (cookie_t) 0; iter++)
{
// get alarm event by it's cookie
alarm_event_t * aevent = alarmd_event_get (*iter);
// check alarm recurrence
int recur = alarm_event_is_recurring (aevent);
// get time of alarm action
time_t ttime = alarm_event_get_trigger(aevent);
// convert GTK's ttime to Qt's DateTime
QDateTime qdtm = QDateTime::fromTime_t(ttime);
// get time part from DateTime variable
QTime qtm = qdtm.time();
// let's count day to current alarm triggering
int days = 0;
QDateTime currDate;
if (timeFrame > 24) // if we need to look forward for more then one day
{
// get current date from system
currDate = QDateTime::currentDateTime();
// calculate seconds from current time to alarm's trigger
int secs = currDate.secsTo(qdtm);
// get full days until alarm
days = secs / (60 * 60 * 24);
}
// here we will form alarm's string
QString sTime;
// using locale settings to convert time into string
sTime = qtm.toString(Qt::DefaultLocaleShortDate);
if (days > 0) // calc for more than 1 day alarms
{
sTime += " (";
sTime += QString::number(days) + tr("d");
sTime += " ";
// calc remaining time
// get current time
QTime currTime = QTime::currentTime();
// calculate seconds remaining to alarm trigger
int remain = currTime.secsTo(qtm);
// we need some fix if get negative result
if (remain < 0) remain += 86400;
// calc remaining hours
int h = remain/3600;
// calc minutes
int m = (remain - h*3600)/60;
// form hour + minutes into QTime to leter get formatted string
QTime remTime(h,m);
sTime += remTime.toString("H:mm");
sTime += ")";
}
// get the title of alarm
QString aTitle;
// each alarm can have Message, Title and AppId
// for the first check the Message
const char * cTitle = alarm_event_get_message(aevent);
aTitle = QString::fromUtf8(cTitle);
if (aTitle.isEmpty())
{
// next, check the title if message is empty
cTitle = alarm_event_get_title(aevent);
aTitle = QString::fromUtf8(cTitle);
if (aTitle.isEmpty())
{
// if message and Title both are empty - use AppID as alarm's title
cTitle = alarm_event_get_alarm_appid(aevent);
aTitle = QString::fromUtf8(cTitle);
}
}
sTime += ": " + aTitle;
aBox->addItem(sTime);
// free alarm event structure
alarm_event_delete(aevent);
}
}
free(list);
}
