Found a free Book for Qt3
by Dr. Nikolaus Klepp 02 Jan '23

02 Jan '23

Hi all! The 2004 book "C++ GUI Programming with Qt 3 (ISBN 0-13-124072-2)" that's mentioned in http://trinitydesktop.org/docs/qt3/how-to-learn-ntqt.html is available for free now at https://www.researchgate.net/publication/245591968_C_GUI_Programming_with_Q… Things to note: - Names changed from "Qt..." to "TQt..." - compiling by hand needs something like "g++ a.cpp $(pkgconf tqt --cflags --libs) -lstdc++" - "qmake -project ..." will not include the TDE folders, so you'll have to add them manually to the *.pro file - When in doubt: http://trinitydesktop.org/docs/qt3/ Nik -- Please do not email me anything that you are not comfortable also sharing with the NSA, CIA ...

Direct shutdown of Block screen (feature request)
by Christian Schmitz 01 Jan '23

01 Jan '23

Hi everyone: First, happy new year. I have a notebook with opensuse tumbleweed and trinity desktop. I configure it to enter on sleep when the lid is closed. I found that several times i open lind and as there is no led or signal that the system is on sleep i press the power button. Actually the system trap the power request, show the unlock screen. But when i write the password the system shutdown. This trigger 2 question/suggest/ideas: 1) The system must allow shutdown even on unlock screen ( or be configurable), is no sense request the password to shutdown the computer because never is required in normal use. ( the login is automatic, and i can shutdown from TDE without password). About software active we can look windows 10 that: Send the shutdown signal and open a "waiting for XXX to close" 2) Normally if the screen is off when the uthe user press power, mean that the user want turn on the computer (only that dont know that already is on). So the user don't want shutdown that is the actual behavior. So i suggest that if the screen is off when the user push the button appear the shutdown options (off, hibernate, suspend ) Best regards Christian -- Be Free, Be Linux

tdevelop

Hi all! I just played around with tdevelop to build a simple test-application. However, I did not succeed. Is there anybody on the list who has actually used tdevelop to build a TQT3 or QT3 application that actually compiled and worked?

2 login sessions at once?
by Michael 17 Dec '22

17 Dec '22

Maybe an odd question? Can you run two, or more, logins for the same user at the same time? (Say the normal one on Crtl-Alt-F7 and an extra one on Crtl-Alt-F5?) I have an app that behaves badly that I’d like to isolate to its own instance of TDE. (There’s no fix for it and when it it goes bad it requires a desktop restart.) Doable? Or anyway to do something equivalent? Thanks all, Michael

Plymouth error
by Thierry de Coulon 17 Dec '22

17 Dec '22

Hello all, As I allready mentioned, I am using MX-Linux at school. I have now installed it on my laptop because it's the only Debian-based distribution I've found where Gnome-Display-Networks is working - which let's me connect my machine with a Microsoft Wireless dongle. To stop any discussion: no, I won't use Ubuntu or Mint, so I haven't tested those. I have installed Trinity on MX and it works well, with one glitch: - If I use TDM (dpkg-reconfigure tdm-trinity) there seem to be some problem at shutdown, wich leads to - sometime, not always - a failure of X to start at boot (I did not write down the message but it's something about a Plymouth failure). If I log in (cli) and then start X it works. - If I use lightdm there is no problem (except the less friendly greeter). From all this, I have concluded that the problem is linked to the use of Trinity's login screen. While I can live with lightdm, does anyone understand what the problem with plymouth is, and/or if it's possible to get TDM's greeter without plymouth? I seem to remember a time where plymouth had to be installed only for some versions of the greeter - maybe I'm wrong. Thierry

Replace <enter> with <shift>+<enter> for OpenSCAD ?
by Dr. Nikolaus Klepp 10 Dec '22

Hi all! Does anybody know if there's a TDE way to replace <enter> with <shift>+<enter> for just one specific application windows? Reasomn is, that the last update broke OpenSCAD input: to vreate a new line it now requires <shift>+<enter> instead of <enter>, which is kind of strange.

However, I do sometimes cheat and use nitter.org, just to read what somebody posted, if it actually gets my attention. Twitter never seemed worth the time, effort, or emotional investment, to participate. I doubt Mastodon can be much better. Life is short. And yet there are people who do use it, so it must be worthwhile to somebody out there. My question is, Why not just have our cake and eat it, too? If we establish "an official communication channel for our project on Mastodon" (quoting Slavek), does that mean that we must choose between them - one or the other? Are they mutually exclusive? We could have, say, an "unoffical communication channel" on Twitter; maybe not the devs themselves, but there are lots of TDE users out there, and they could take the message to the people on Twitter, the good news that there really is a Linux desktop that is actually worth using.

Speaking of this, is it possible to get thumbnails in the "tree" or "detailed list" views? I primarily use these and it only shows an image of the MIME type (a picture, a video)
