The correct answer with Qt is to use signals and slots (http://qt-project.org/doc/qt-4.8/signalsandslots.html) so you will need to add to the form1 a signal with a QString parameter (this will be emitted in the slot that is connected to clicked signal of the button you use to submit the data obviously with the parameter you need) and to the form2 you add a slot with a QString parameter (that sets the QString wherever you need it in form2) and connect those two where you have access to both forms.

Or a second method is to do it with a simple call to a member function of form2 (if you don't already have a pointer to form2 you will need one) - the first solution involves more coding, but that is the recommended way to do it.

For using a virtual keyboard you should implement an input context plugin.

You can type in "Qt input context plugin" into your favourite web search engine or type in "Input panel example" into your Creator/Assistant help panel.
