New Virtual Keyboard for Qt Enterprise

Published Tuesday February 4th, 2014 | by

One of the items those who create embedded touchscreen devices with Qt often request is a good, extensible virtual keyboard. We have listened, and I am extremely happy to announce that a Technology Preview of the new Qt Virtual Keyboard is available as a value-add component for Qt Enterprise customers.

There is already a simple virtual keyboard available for Qt Enterprise Embedded, but now we are releasing a Technology Preview of a new and completely re-implemented virtual keyboard. It provides a solid base to be used in various different embedded devices, especially ones with a touchscreen user interface. Because the virtual keyboard is fully licensed under Qt Enterprise, it can easily be included into all kinds of embedded devices without concerns for 3rd party license compatibility, as well as extended with both commercial and open-source spell checkers and word prediction engines. The new virtual keyboard allows for a fully custom visual appearance. We provide two example styles with the Technology  Preview: one modern and one retro style.

English keyboard layout:

Arabic keyboard layout:

Retro style:
vkb3

 

Highlights of the virtual keyboard Technology Preview include:
  • Solid C++ backend and versatile Qt Quick UI
  • Fully customizable graphics and styling
  • Scalability to different screen sizes and resolutions
  • Support for different keyboard layouts – English, Finnish and Arabic included in the technology preview
  • Automatic capitalization, character preview and alternate keys list (e.g. for accents and additional characters)
  • Can be included into a Qt application or used as a system’s default input method
  • Word prediction support with reference implementation using Hunspell, with selection list support for choosing the right suggestion
  • Possibility to extend with other input methods using C++ or Qt Quick APIs

The following video contains a short overview of the key functionality of the new virtual keyboard as well as a demonstration of how nicely it integrates with Qt Enterprise Embedded:

The virtual keyboard technology preview is available for download from the Qt Enterprise Customer Portal, or via the Qt Enterprise online installer. The technology preview is intended for Linux, embedded Linux and embedded Android on top of Qt 5. The virtual keyboard will also be a pre-integrated component in the upcoming major update of Qt Enterprise Embedded. For more information, please check out the virtual keyboard product page.

If you are not already a Qt Enterprise customer, check out our free 30-day evaluation.

 

As always, we are eager to hear how we should improve the virtual keyboard to better match the needs of our customers. We encourage you to have a look at the Technology Preview and tell us what you think. You can contact us via email at Qt.Enterprise-Controls@digia.com, or via the contact us form.

I appreciate the most in touch keyboards the swipe feature…
It’s really helpful to compensate for slow typing.

Tuukka Turunen says:

@Lilian: It is possible to integrate this with 3rd party prediction engines such as swype, if needed.

J says:

This feature is really great for embedded.

Sylv says:

Thank you for this component, will it be available on other platforms (Windows) ?

Tuukka Turunen says:

@Sylv: Yes, it is our intention to have it available also for other platforms, including Windows. Main use case is in embedded, thus the focus has been in eLinux and eAndroid first.

Martin says:

That’s nice to hear! Thank you!
