All applications are available in the official repository and no third-party sources required. Now, let's start exploring them!

Alternatives to Visual Basic

This is a list of free/libre open source software (FLOSS) alternatives to Visual Basic (part of Microsoft Visual Studio) computer programming platform. If your school is still teaching VB 6, or if you now use Ubuntu for programming classroom, we strongly suggest you to switch to either one of these alternatives. With these, one can create computer programs visually by drag and drop as well as coding just like what one can do with VB.

Comparison of File Chooser Dialogs

Hello, convenience lovers! We are all using GNU/Linux technologies. Ever dissatisfied when doing open/save in your application? Perhaps you want it to show you thumbnails preview but not, allows modes other than list view but not, provide search but not, display recent files but not, or you expect it puts all storage disks right at the front but not. I will help you choose a technology you can see below between KDE, GNOME, Elementary OS, Deepin, and LXDE so you can decide which distro you will use or even share with family later.

(File dialog from Deepin is the best file dialog in all GNU/Linux techs today)

Setup Complete Qt SDK on Ubuntu Eoan Ermine

Qt Software Development Kit (Qt SDK) includes Qt Creator IDE & Qt Framework Libraries with Full Code Examples among other things. On Ubuntu 19.10, if you want to develop GUI applications with Qt, you need to install that Qt SDK first with a C++ compiler. Installing it on 19.10 is slightly different to different to 18.04 as this involves configuring GNU GCC C++ compiler on 19.10. After setup, you will have a ready, complete Qt SDK with Creator, Designer, Linguist, and Assistant works with G++ compiler. I hope this will be useful for you all. Happy hacking!

(Qt Creator works perfectly on Ubuntu 19.10)

Setup Complete Qt Development Tools on KDE Neon

(Qt Creator IDE showing user interface design of a program)

Neon GNU/Linux recently gained more popularity and it is good to start Qt5 application development on it because Neon is an operating system built upon both latest Qt and KDE. With Qt5, you can create perfect and cross-platform GUI applications working on GNU/Linux and other OSes. Qt5 development here uses C++ language by default and gives you advanced user interface designer. And with Neon you can easily install and update latest Qt Software Development Kit (SDK) to support your development. This setup tutorial includes the IDE, framework (libraries), C++ compiler & debugger, complete documentation and examples, as well as other necessary programs. If last January I presented you Neon for Designers, then now is the time for Neon for Programmers. I hope this tutorial helps every new programmer in Qt. Happy hacking!

Fix "Cannot mix incompatible Qt library" on KDE Neon 5.10

Subscribe to UbuntuBuzz Telegram Channel to get article updates directly.

I found that after installing KOrganizer on KDE Neon 5.10, the system experienced error in which I cannot login properly to desktop. The only clue is an error message saying that there is incompatibility in Qt library versions. The solution in my case is by apt-get upgrade:

Problems

KOrganizer failed to start.
KDE applications failed to start (Spectacle and Dolphin).
After reboot, it failed to login to desktop. It shows only blank screen (except I still can login to tty).

My specification: Neon 5.10 operating system on a 64bit laptop.

Error Message

Cannot mix incompatible Qt library (version 0x50701) with this library (version 0x50900)

Solution

Previously, I reinstalled KDE Neon 5.10 just because of this problem. Once installed, I encountered this problem again! But finally I recognize that I just need to upgrade all packages to solve it:

Note: I didn't do apt-get dist-upgrade and it's OK. So in this case, dist-upgrade command is not needed.
