| Issue |
We are developing a hand writing program. We need to send a character from hand writing program to PED.
How can we inject character to PED, text widget, or browser?

| Solution |
If you want to inject a key to the widget that currently has focus, you can create a key event and emit from any region.
e.g.
x09PhEvent_t event;
x09PhKeyEvent_t key;
x09
x09PhRect_t rect = {SHRT_MIN, SHRT_MIN, SHRT_MAX, SHRT_MAX);
x09memset(&event, 0, sizeof(event));
x09memset(&key, 0, sizeof(key));
x09event.type = Ph_EV_KEY;
x09event.emitter.rid = fep_ff->rid;
x09event.num_rects = 1;
x09event.data_len = sizeof(key);
x09event.input_group = ig;
x09key.key_flags = Pk_KF_Key_Down | Pk_KF_Cap_Valid;
x09key.key_cap = key.key_sym = c;
x09PhEventEmit(&event, &rect, &key);
The rid is the region id of where you want to emit from. |
