Prevent computer sleep

[mdalacu]

Hi. I need help to modify my application to prevent computer entering sleep state while the app is doing something....
On windows i achieve this like so:

Code: Pascal  [Select][+][-]

1. {$IFDEF Windows}
2.    SetThreadExecutionState(ES_CONTINUOUS OR ES_SYSTEM_REQUIRED OR ES_AWAYMODE_REQUIRED);
3. {$ENDIF}

Any ideea on how can i do this on Linux..manly Ubuntu 18.04 x64.
Thank you very much.

No one? Any hint is appreciated...

What I can find is this, where FPC should be capable of doing both, however I prefer the dbus way as X may not be available in the future when wayland finally takes over. See: http://wiki.freepascal.org/FPC_and_DBus

Yes, I agree, but the wiki entry is not finished and a bit marginal. There is far better code however:
If you are new to dbus programming maybe these articles by Michael can Canneyt can help:
https://www.freepascal.org/~michael/articles/#dbus1
https://www.freepascal.org/~michael/articles/#dbus2
sources: https://www.freepascal.org/~michael/articles/dbus2/dbus-code.zip

Thank you both! :-)
@Thaddy The sorces posted for dbus does not compile anymore so i will try using dbus-sent in a Tprocess
Thank you again.

Yes i Saw that. A quick Fix is to make the property a VAR

@Thaddy Please, can you be more specific?
What did you changed in order to compile the 2 bundled examples? Thank you.

[mdalacu]

Me again...i am unable to sort this out... :/ It is beyond my skills.
Could someone provide an quick example how to call a dbus method using dbus unit from fpc? "dbuscomp" i am unable to make it to compile.
Thank you very much.

check if  the dbus shared libraries have the extension .so and not so.1 or something. If so, create a symlink or copy.

This is not the problem.
I need an working examle using dbus unit as the wiki is incomplete or an updated dbuscomp unit which i could compile. The posted one has methods which are no longer available in dbus.
Thanks again.

[Thaddy]

OK I will come up with something new (but these calls are still available afaik AND tested!) Not based on the wiki but based on the article.

[mdalacu]

Thank you @Thaddy.  I am waiting eagerly for your example.

[mdalacu]

Please, just an working example of using dbus...it's all i need... i hope... :-)

I do not always have time to do it right away.
