Howto implement a multi-tap input method for qt5?

jackylau

Hi, all.
I'm working on a embedded project which has only one qt5 app running in frontend. The device we using has a 3x4 number keypad, and we want to implement a multi-tap input method for qt5. Can anyone tell me that how can we do that? Are there any document and example?

Did you get the answer for your question?

as long as the touchscreen and OS supports it, Qt will also support it.

Hi Raven,
I dont think so if Jacky is speaking about "touch screen" application.

What i understand is, he has a "numpad" keyboard in his device. Something like low-end mobile phone. Where, each key is mapped to "three" alphabets.

And he want to know, if Qt has a facility to take input as "multi-tap"

I have a the same scenario in my case.

I know that there are some input methods hints

Qt::ImhHiddenText
Qt::ImhNoAutoUppercase
Qt::ImhPreferNumbers
Qt::ImhPreferUppercase
Qt::ImhPreferLowercase
Qt::ImhNoPredictiveText

For example, if we want to allow entering only numbers , we can set the method hint as Qt::ImhPreferNumbers. What i think is, Qt will open "numpad" for entering numbers.

Is there any way, where i can get "multi-tap" keyboard on screen or dont show the keyboard but take the input as "multitap"?
