Screen Shot


About this
First time, i prepared this project for continue my thread The way to E6/A1200 Native EZX Application
for show how can made the simple app with the qelib.
But since it may be the useful app, then i decided to sepearate it to this new thread.

Feature
Now work as Lap time only, coz i not known about function of real StopWatch enough ,
then you can modified the source code for made it suitable to you,
or let me know about other feature of the stopwatch.

Bugs
- Still not sure this can work on every firmware or not.
- Other bugs ?

Author note
About source code, Sorry if my source code ugly a lot

Attachment
Mpkg package: qestopwatch-0.0.1-dev-preview.pkg.zip
Source code: QEStopWatch-0.0.1-dev-preview.tar.gz.zip

I need to know about kind of StopWatch

Ok, in first show i have Lap time StopWatch already,
but Is there other kind ? and How does that kind work ?

And In game show or in any game which need to capture each time by person race,
What is kind (or name) of that stopwatch ?
Split Time, Rank Time .. or other ?

And other kinds....

Please suggest me.

Donga I'm sorry but I cant help you with the stopwatch there mate, but maybe a timer too can be incorporated within the same app?

Keep up the good work.

Not at all, Akshay

First time, I 'd designed for user select type of StopWatch before goto the Main screen of StopWatch but on this release i mark it as comment in the source code.
So, i think it can have more than one type of stopwatch.

My app use QTimer for displaying only (refresh every 10 millisecs.).
For accuracy time capture, i used QTime istead of QTimer. QTime can use more than one instance and claimed by Trolltech about accuracy on QT Documents

Detailed Description

The QTime class provides clock time functions. A QTime object contains a clock time, i.e. a number of hours, minutes, seconds and milliseconds since midnight. It can read the current time from the system clock, and measure a span of elapsed time. It provides functions for comparing times and for manipulating a time by adding a number of (milli)seconds.
QTime operates with 24-hour clock format; it has no concept of AM/PM. It operates with local time; it does not know anything about time zones or daylight savings time.
A QTime object is typically created either by giving the number of hours, minutes, seconds, and milliseconds explicitly, or by using the static function currentTime(), which makes a QTime object which contains the system's clock time. Note that the accuracy depends on the accuracy of the underlying operating system; not all systems provide 1-millisecond accuracy.
The hour(), minute(), second(), and msec() functions provide access to the number of hours, minutes, seconds, and milliseconds of the time. The same information is provided in textual format by the toString() function.
QTime provides a full set of operators to compare two QTime objects. A time is considered smaller than another if it is earlier than the other.
The time a given number of seconds or milliseconds later than a given time can be found using the addSecs() or addMSecs() functions. Correspondingly, the number of (milli)seconds between two times can be found using the secsTo() or msecsTo() functions.
QTime can be used to measure a span of elapsed time using the start(), restart(), and elapsed() functions.

Still wating for other suggestions .....

I have a package that i use has a stop watch and all sorts just not touch screen compatible. It's called mtoolbox. Its a java app though

[herambt]

tdry editing it with JAM (Java Adapter Machine). You will find it elsewhere in this site. If I get the link, I will post it.

Hi Donga,

I only just came accross this, but as someone who uses stop watches at motorsport events, it's not a bad start. I like it.

Here are my list of things to look for in a stop watch:

1) I like the fact that as each lap passes I am able to see the previous laps listed above.
2) It would have been nice if the 'Best Lap' could have been highlighted and stay in view all the time while the laps (race) is still in progress.
3) On the E6 the 'Best Lap' summary does not work. It would be nice if it did.
4) The ability to save a series of laps (a race), would be a plus also, even if just in some simple text form.
5) The ability to do splits (between 2 cars for instance) during a lap would also be helpful.
6) A big plus for stopwatches now is the ability of timing at least 4 cars at once. Maybe not all the features of the above for the other cars, but the ability to track them.

Hope this helps.
I'll be using it this raceweekend to see how it works.
