Qt Quick Component S60v5
I have a QML-based application which is deployed on my Nokia 5230 phone, there are several TextInput components, when the component takes the input focus, input method status indicator changed, but virtual keyboard does not appear.

The Symbian OS platform is formed of two components: one being the microkernel-based operating system with its associated libraries, and the other being the user interface (as middleware), which provides the graphical shell atop the OS. The most prominent user interface was the S60 (formerly Series 60) platform built by Nokia, first released in 2002 and powering most Nokia Symbian devices. UIQ was a competing user interface mostly used by Motorola and Sony Ericsson that focused on pen-based devices, rather than a traditional keyboard interface from S60. Another interface was the MOAP(S) platform from carrier NTT DoCoMo in the Japanese market. Applications of these different interfaces were not compatible with each other, despite each being built atop Symbian OS. Nokia became the largest shareholder of Symbian Ltd. in 2004 and purchased the entire company in 2008. The non-profit Symbian Foundation was then created to make a royalty-free successor to Symbian OS. Seeking to unify the platform, S60 became the Foundation's favoured interface and UIQ stopped development. The touchscreen-focused Symbian^1 (or S60 5th Edition) was created as a result in 2009. Symbian^2 (based on MOAP) was used by NTT DoCoMo, one of the members of the Foundation, for the Japanese market. Symbian^3 was released in 2010 as the successor to S60 5th Edition, by which time it became fully free software. The transition from a proprietary operating system to a free software project is believed to be one of the largest in history. Symbian^3 received the Anna and Belle updates in 2011.
However, some important components within Symbian OS were licensed from third parties, which prevented the foundation from publishing the full source under EPL immediately; instead much of the source was published under a more restrictive Symbian Foundation License (SFL) and access to the full source code was limited to member companies only, although membership was open to any organisation. Also, the Free software Qt framework was introduced to Symbian in 2010, as the primary upgrade path to MeeGo, which was to be the next mobile operating system to replace and supplant Symbian on high-end devices; Qt was by its nature free and very convenient to develop with. Several other frameworks were deployed to the platform, among them Standard C and C++, Python, Ruby, and Adobe Flash Lite. IDEs and SDKs were developed and then released for free, and application software (app) development for Symbian picked up.
With market share sliding from 39% in Q32010 to 31% in Q42010, Symbian was losing ground to iOS and Android quickly, eventually falling behind Android in Q42010. Stephen Elop was appointed the CEO of Nokia in September 2010, and on 11 February 2011, he announced a partnership with Microsoft that would see Nokia adopt Windows Phone as its primary smartphone platform, and Symbian would be gradually phased out, together with MeeGo. As a consequence, Symbian's market share fell, and application developers for Symbian dropped out rapidly. Research in June 2011 indicated that over 39% of mobile developers using Symbian at the time of publication were planning to abandon the platform.
Despite these efforts to be generic, the UI was clearly split between competing companies: Crystal or Sapphire was Nokia, Quartz was Ericsson. DFRD was abandoned by Symbian in late 2002, as part of an active retreat from UI development in favour of headless delivery. Pearl was given to Nokia, Quartz development was spun off as UIQ Technology AB, and work with Japanese firms was quickly folded into the MOAP standard.
If you got an error message while installing AppList that any Qt-related components or libraries are missing or see only a black screen when launching the app you may need to install or update your Qt libraries.
