HID keyboard Unhandled key code 10036 !

Hello all,

im developing android application to catch key strokes.
As far as im using real keyboard, all works fine...

However, if i use:

Code:

---

Keys.onPressed: { JS.keyboardListener(event.key); }

---

them im having the error:
W libInventory_armeabi-v7a.so: Unhandled key code 10036 !

so, does the application use some virtual keyboard which cant handle its keys?
is there a way to convert them into common ones so they will correcspond to real ascii keys?

Basicaly, im just low in c++, therefore what I tried is to install nativeEventFilter, exactly this way (just main.cpp simple approach):

Code:

---

#include <QAbstractEventDispatcher>
#include <QAbstractNativeEventFilter>
 
class MyAppNativeEventFilter  : public QAbstractNativeEventFilter
{
    virtual bool nativeEventFilter(const QByteArray &eventType, void *message, long *result) override;
};
 
int main(int argc, char *argv[])
{
    QGuiApplication app(argc, argv);
 
    // Native Filter
    MyAppNativeEventFilter filter;
    app.installNativeEventFilter(&filter);
 
    return app.exec();
}

but it just gives me thre errors while compile:

Code:

---

C:\Qt\Projects\Sources\Inventory\main.cpp:-1: error: error: undefined reference to 'vtable for MyAppNativeEventFilter'
:-1: error: the vtable symbol may be undefined because the class is missing its key function
:-1: error: linker command failed with exit code 1 (use -v to see invocation)

---

so I would very much kindly like to ask you if you can help me on this issue

Your code declares the existence MyAppNativeEventFilter and its nativeEventFilter() function but does not provide an implementation. The abstract class requires an implementation of the nativeEventFilter() function. A minimal implementation could just return false; something like:

Code:

---

// Declare
class MyAppNativeEventFilter  : public QAbstractNativeEventFilter
{
    virtual bool nativeEventFilter(const QByteArray &eventType, void *message, long *result) override 
};
 
// Implement
bool MyAppNativeEventFilter::nativeEventFilter(const QByteArray &eventType, void *message, long *result) override 
{
    return false;
}

---

Code:

---

expected function body after function declarator

---

on line:

Code:

---

bool MyAppNativeEventFilter::nativeEventFilter(const QByteArray &eventType, void *message, long *result) override

ChrisW67 forget to add a semicolon after the function declaration. Don't just blindly copy code and paste it into your application. Think about the answer before you use it.

Indeed, I originally inlined the implementation and then copy-n-pasted myself into the missing semicolon ;)
