LTS

Qt 5.6 is a supported LTS release. I think it deserves to be on the main page, especially if 4.8 is there.

  • Qt 5.9 is the current LTS release replacing Qt 5.6.
    • Qt 5.9 doesn't replace Qt 5.6. It is still supported. 5.6.3, and if the 3 year support promise is kept, also 5.6.4 and hopefully 5.6.5 will be released. So it needs to be in that table if Qt 4.8.7 is there and as long as there are releases to be made for 5.6. Just keeping 4.8 and 5.9 makes it like there is no other choice for users. This is a disservice to your users. Actually you shouldn't recommend 5.9 so eagerly, at least not until 5.9.2 is released, i.e. not until many regressions and P1 issues are resolved. Until that time, 5.6 remains a good recommendation for conservative users.
      • As the table says, it is current releases, for Qt4 that is 4.8.7, Qt5 is 5.9. Both 5.8 and 5.6 (5.7 support time ended 15.6.2017) are right now still both supported, but not listed on the frontpage, they are in the all releases table.


Q: Entry "Overview" on the Main page does not link to an existing page. Category General (to which this entry is linked) does not exist. Should this entry be deleted?

A: This seems gone now.

EOL version in tutorial

Is it OK to edit tutorials to eliminate references and instruction about EOL versions like 12.10 Ubuntu specific instructions (EOL since 2014) or Qt 4 specific instructions (EOL since 2015).

For example see

A: This should be fixed.

Still under active development?

Is this wiki (especialy the german part) under active development? It doesn't seems so...

Best regards

A: This wiki is community-maintained. It certainly could use some love.

QT Installer Framework

I was building source file qt-installer-framework but I have some issue when building. Help me step by step to build source qt-installer-framework on Windows.

A: Please ask in the Qt forum.

scrollbar issues in Qt Creator

(I am a new user to the forum and I am not sure if this should be here, but the bug is really annoying)

This bug concerns the Qt Creator IDE (17.0.0) and does not affect software using the Qt Framework.

When I edit my code in Qt Creator, I sometimes (most of the time) cannot reach the end by scrolling, the scrollbar appears to be at the end but there is still code in the file that has not been displayed. Then I have to press the down arrow on my keyboard to manually scroll downwards. If this is not frustrating enough, after using the down arrow to scroll downwards, scrolling upwards cause the scroll view to jump to random sections of the code, sometimes far beyond the end of the file.

This bug has made coding in Qt Creator very annoying (but still better than VS Code, at least Qt Creator does not crash). I would really appreciate if this bug could be fixed maybe in the next version. The previous version did not have this bug.

The description may not be clear to you, but you would know if you are experiencing the same issue. I am on Windows 10 64bit, using a copy of Qt Creator 17.0.0 that is built on Jun 17 2025 16:32:24 based on Qt 6.9.1 (MSVC 2022, x86_64), and it is from revision 4983f08c47

summary in Singlish: Qt Creator 17.0.0 scrollbar blur leh

A: The Qt Creator developers are aware of this issue and are working on it.

Industrial-Scale Prototyping and High-Fidelity Additive Manufacturing: Navigating the Fused Deposition Modeling (FDM) 3D Printing Market Forecast

The global educational and specialized small-to-medium enterprise (SME) landscape of early 2026 is defined by a rigorous focus on "democratized-innovation" and the maintenance of high-accessibility standards for rapid prototyping. FDM 3D printing has emerged as a foundational technology in this environment, offering a versatile solution for diverse sectors ranging from architectural modeling to consumer product design. Valued for its exceptional ease of use and the availability of low-cost, bio-based filaments like PLA, it is essential for the "safety-first" supply chain in STEM education and localized "maker-space" ecosystems. As global sectors face increasing pressure to foster domestic technical skills, the role of Desktop FDM Printers has become paramount for providing the structural and creative foundations of modern, high-cycle product design.

According to a recent report by Market Research Future, the Fused Deposition Modeling 3D Printing Market is witnessing a transformative era of growth driven by the expansion of the global consumer goods, fashion, and specialized research sectors. The global industry is projected to grow from USD 2.55 billion in 2025 to approximately USD 15.09 billion by 2034, exhibiting a steady compound annual growth rate (CAGR) of 21.8%. This trajectory is a central focus of the latest FDM 3D Printing Market Forecast, which identifies Prototyping as the primary application driver, while the Healthcare segment is recording the fastest gains due to the rising demand for customized anatomical models and surgical guides. Geographically, North America leads the market in terms of software and service integration, while the Asia-Pacific region accounts for the highest volume of desktop printer shipments.

Looking toward 2035, the market is poised to be redefined by "High-Resolution Multi-Material Extrusion" and the expansion of the "sustainable-filament-recycling" niche. We are seeing a significant move toward the development of FDM printers that utilize recycled plastics and bio-polymers, helping designers align with tightening global ESG mandates and "circular-design" principles. Additionally, the move toward "Cloud-Integrated Distributed Manufacturing"—where design files are sent to local FDM hubs for immediate production—is helping the industry achieve its long-term objective of reducing global logistics carbon footprints. By 2035, the market will likely be defined by Creative Integrity, providing the essential, low-impact, and high-fidelity hardware foundations required to support a more technologically advanced and ecologically responsible global design infrastructure.
